15 Easy Kitchen Science Experiments (With Ingredients You Already Have)

Krystal DeVille

September 19, 2023

Kitchens aren’t just for parents and making meals!

Kids can use kitchen ingredients and tools to learn from kitchen science experiments. Check out the following ideas for fun kitchen science.

—–You can download our FREE ebook with 25 STEM Activities here——

Table of Contents

1. Rubber Egg Experiment

• White vinegar
• Glass or jar

Cover an egg in a container with vinegar to see the shell disappear and the resulting egg that feels like rubber. Children learn about the chemical reaction between the eggshell (calcium carbonate) and the vinegar (acetic acid). Bubbles on the egg and on top of the water are from carbon dioxide. 

2.  Shaking for Butter

• Heavy whipping cream
• Jar with lid
• Sealable plastic bags

Using heavy whipping cream at various temperatures, kids shake the cream in a jar to observe changes in color and texture. They learn about emulsification and the butter-making process of churning, in which cream is agitated and fat particles begin clumping together. They can see whipped cream form first, followed by butter, when the air is no longer held by the cream.

3.   Bread in a Bag

• Plain flour
• Granulated sugar
• Rapid rise yeast

Your children mix ingredients to make dough in the plastic bag, then knead the dough to bake. They discover how yeast is a dormant fungus that can be awakened with warm water and sugar as a food source for fermentation. Children also observe bubbles that form when the yeast eats the sugar and gives off carbon dioxide.

4. Growing Plants from Food Scraps

• Pineapple top
• Green onion white root sections
• Avocado pit
• Wide-mouthed, clear jars or glasses

Kids poke toothpicks into a pineapple top and avocado pit and prop over jars filled with water, while the white (root) ends of the onions are placed directly in water. They can see how roots grow on the pineapple and avocado and how the green ends of the onions poke from the top as the roots in the water continue to grow. 

5. Lemon Volcano

• Craft sticks
• Food coloring
• Baking soda

Your kids place cut lemons in the bowl with dish soap, food coloring, and baking soda poked in with craft sticks. They observe the reaction between the acid (lemon) and base (baking soda). Carbon dioxide is released and appears in the bubbles, made even more visible with the help of the dish soap that captures the gas.

6. Rock Candy

• Bamboo skewers or wooden sticks
• Large glass jar

Children squirt colors into the water you’ve heated and added sugar to melt. They roll moistened sticks in dry sugar to make the seed crystals, then place those in the jar of the cooled mixture. See how a saturated solution allows the sugar molecules to bump into each other and start sticking together.

7. Baked Potato Science

• Large potatoes
• Plastic wrap
• Baked potato pins

Kids predict which method of cooking a potato will be the fastest in the regular oven: plain potato, in foil, with baking pin, in foil with baking pin OR in the microwave plain or in plastic wrap. They explore how the wrappings may hold heat within to steam, whether the pin helps heat enter the potato sooner, and if a microwave is faster than a traditional oven.

8. Magic Milk

• Milk (whole or 2%)
• Cotton swabs

Your children squeeze colors into a shallow dish of milk and then touch the milk with a swab soaked with dish soap, to see the various colors of milk shoot away from each other. They learn that fat in milk is a nonpolar molecule, which doesn’t dissolve in water. The soap makes the fat separates from the water.

9. Solar S’Mores

• Small, low boxes, such as pizza boxes
• Black construction paper
• Foil & plastic wrap
• Long wooden skewers
• Graham crackers
• Marshmallows
• Chocolate bars

Kids make their own solar ovens with the first 4 items and then build s’mores with the food ingredients. On a sunny day, they observe the effects of solar energy to melt the chocolate and make the marshmallows puff. Discuss the purpose of the foil (reflection) black paper (heat absorption) and plastic wrap (heat retention).

10. Walking Water

• Test tubes with rack OR clear plastic cups/jars
• Paper towels cut into thin strips

Children add water and different colors to the containers and stir, then place the paper towel strips into the containers, with two ends in each. They can see how the colored water “walks” through the fibers and spreads to meet and mix. This is a capillary action, which is the same way that plants, such as celery, take in water.

 11. Cake Experiment

• Baking powder
• Cooking oil
• Ramekins OR other small baking dishes

Bake four different cakes with the kids, leaving one important ingredient out of three: oil, egg, or baking powder. Kids predict the various effects in looks and flavor related to each missing ingredient. They learn that eggs add color, flavor, and structure; oil adds moisture and tenderness; and baking powder makes the cakes rise with its release of carbon dioxide.

12. How Does Salt Affect Ice?

• 5 clean tin cans
• Coarse rock salt
• Measuring spoons
• Digital thermometer (no-contact type)

Have children add the same number of ice cubes to each can and then add a teaspoon or 2 tablespoons of either table salt or rock salt into each, shaking them a bit to spread the salt. They observe condensation on the bottoms of the cans as the reactions begin. Help them take temperature readings to compare the effects in each can.

13. Sandwich Bag Compost

• Food waste in small pieces (veggies are best)
• Cardboard egg carton pieces
• Sandwich bags

Kids add the first two items with a bit of water to individual bags with the tops zipped most of the way and a straw inserted into a gap for air. Mush it up a bit each day and add more water, if needed for moisture. They observe on a small scale how composting turns food waste into soil.

14. Explore the Density of Liquids with Salt

• Clear glass
• Vegetable oil

Children pour oil into water to observe what happens, adding a drop of color on top, followed by larger and larger sprinkles of salt. They offer ideas of why the various movements take place. They learn water is denser than oil and salt are denser than the liquids.

15. Ice Cream in a Bag

• Small zipper sandwich bag
• Gallon-sized zipper bag 

In the small zipper bag, your child adds the first 3 ingredients and zips closed. Add salt and ice to the large bag and place the small bag inside the larger one and seal. They shake to make ice cream! Children can learn that salt (sodium chloride) lowers the freezing point of water so it can become even colder .

These kitchen science experiments are easy and require little planning! They’re great activities to learn the scientific method and for some of these food experiments, you can enjoy a tasty treat afterward too!

Safety Considerations with Edible STEM Activities

When conducting edible STEM activities, it is essential to prioritize safety to ensure a positive and secure learning experience. You should always have adult supervision when conducting experiments with children, especially if the experiment involves heat or sharp objects. It’s also a good idea to have a basic first aid kit on hand for minor injuries like cuts or burns. Make sure adults know how to use it.

Before you begin any experiment where there are potential hazards, explain the risks and hazards associated with the experiment in a way kids can understand. Encourage them to ask questions about safety.

Maintaining a clean and hygienic environment is important. Participants should wash their hands thoroughly before handling food, and utensils, surfaces, and equipment should be cleaned properly to prevent cross-contamination and foodborne illnesses.

Consider any known allergies or dietary restrictions of the participants when planning your edible science experiments. Make sure to choose ingredients that are safe for all participants.

You also want to ensure that the ingredients used are safe for consumption and make appropriate substitutions when necessary. Only use food-grade ingredients that are safe for consumption. Check for expiration dates and quality of ingredients.

• 7 Food Science Experiments to Promote Healthy Eating
• After School Activities

Share This Activity

September is Childhood Obesity Awareness Month, and it’s an ideal time to teach students about the benefits of healthy eating.

The percentage of children with obesity has more than tripled over the past 40 years. In fact, about one in five school-aged children (ages 6–19) are considered obese, according to the Centers for Disease Control and Prevention (CDC).

The Effects of Childhood Obesity

Children with obesity are more likely to have hypertension, high cholesterol and asthma, among other health conditions. They also have an increased risk of developing serious health problems as adults, like heart disease or type 2 diabetes. Childhood obesity can also have emotional consequences, such as low self-esteem, anxiety and depression.

Obesity doesn’t only affect children’s physical and mental health; it also has an adverse effect on their academic performance. Past research found that obese students, especially girls, tend to have lower test scores than their peers, are more likely to be held back a grade and are less likely to go on to college.

Food Science Experiments for Kids

While many factors contribute to childhood obesity, like genetics, metabolism and lack of exercise, adopting healthy eating habits can be effective at preventing the condition. The following food science experiments explore concepts like calories and fat to encourage students to make healthier food choices:

Fatty Foods

Objective: Learn a simple way to test the amount of fat in different foods.

Overview: Students will use the paper bag test to compare the amount of fat in apples, butter, potato chips and other foods. The experiment also provides an opportunity for students to learn the difference between unsaturated (good) and saturated (bad) fat, plus the effects of eating too much “bad” fat.

Testing for Glucose and Starch

Objective: Use simple tests to determine the presence of glucose and starch in everyday foods.

Overview: All foods contain chemicals, and glucose and starch are among the most common ones. Before starting the experiment, use this article to explain the difference between starch and glucose, and their effects on the body. Then, conduct this experiment to find these chemicals in foods like marshmallows, peanut butter and applesauce.

Source: Discovery Education

Water Content in Fruits and Vegetables

Objective: Understand the nutritional value of the water content of fruits and vegetables; Encourage students to think about the properties of healthy foods.

Overview: Many fruits and vegetables contain water, but it doesn’t always mean they are filled with key vitamins and minerals. For this experiment, students will measure the water content of the fruits and vegetables, and compare the results to the food’s nutrient value. At the end of the experiment, they should know whether or not each food’s water content is associated with its nutritional value.

Source: education.com

How Greasy Are Your Potato Chips?

Objective: Investigate how much fat is in typical potato chips and potato crisps.

Overview: Potato chips is one of the most popular snacks, but some varieties contain an unhealthy amount of fat. In this experiment, students will look at four different kinds of chips and crisps to test how much fat each product contains. Be sure to explain how our body uses fat and the effects of consuming too much of it.

Source: Science Buddies

Energy Content of Food

Objective: Build a simple tool to determine the amount of calories in certain foods.

Overview: Designed for middle school students, this experiment explores concepts like calories, the caloric value of different foods and the amount of calories children should consume in one day. Students will build a simple calorimeter to measure the amount of heat given off when food is burned to determine the caloric value of bread, cheese and other food samples. This experiment requires students to burn the food using matches, so adult supervision is a must!

Demystifying the Sugar Buzz

Objective: Learn the different effects that sugar and starch have on the body.

Overview: Sugar enters the bloodstream faster than starch (found in foods like flour, potatoes and beans), causing a “sugar buzz.” This experiment will demonstrate how fast, or slow, sugar and starch pass into artificial blood.

Source: howstuffworks

Upcycling Food Scraps

Objective: Find low-cost, sustainable ways to grow and eat organic foods.

Overview: Buying healthy, or organic, produce can be expensive. This infographic from Whole Foods provides steps on using food scraps to easily regrow food. To demonstrate food upcycling, choose one of the foods listed in the infographic - like green onions, celery or sweet potatoes - and create a food garden in your classroom.

Using The Scientific Method With Kids

The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is tested with an experiment to prove or disprove its validity.

Sounds heavy… What in the world does that mean?!?

The scientific method can be used as a guide to help lead the discovery process. You don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.

As kids develop practices that involve creating, gathering data, evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation.

Even though the scientific method seems like it is just for big kids, it can be used with kids of all ages! You can have a casual conversation with younger kiddos or do a more formal notebook entry with older kiddos (free printable below).

Love the cookie cutter idea. My little preschooler loves this mini science experiment: milk in bowl, food coloring drops and swirl with toothpick. Entertains for a good 20-30 minutes every time.

it’s never too late to share this on #kidsinthekitchen 🙂 http://lookwhatmomfound.com/2014/05/peanut-butter-oatmeal-power-bites-kidsinthekitchen.html

These are so cute and fun! Science experiments are always a hit with the kids. Thank you for sharing!

I am always intimidated by doing science experiments with my boys. I know they’d love them… but science was not my thing. So I shy away from them. These look so easy though, we may have to give ’em a try! Thanks for sharing on Makeovers & Motherhood’s Welcome Party Wednesday Link-Up! I am featuring you this week!

It is great when we can use items we already have at home to help our children have fun learning! These are wonderful ideas that are easy to prepare. And I love that you contained each on a separate tray, should make clean-up a bit easier. Thanks for sharing at the Thoughtful Spot Weekly Blog Hop!

Everyone loves what you guys are up too. This kind of clever work and exposure! Keep up the terrific works guys I’ve added you guys to my blogroll.

Food Fat Test Kitchen Science Experiment

In this fun and easy kitchen science experiment for kids, we’re going to test and see which food contain fat. 

• A sheet of white printer paper
• Potato chip
• Peanut butter

Instructions:

• Draw six circles on the piece of paper.
• Label each circle with the name of the food you will be testing.
• Rub a tiny bit of food on each circle.
• Allow to dry for thirty minutes.
• Examine each circle. Some will be dry and some will be greasy. The greasy spots are residue from fats in the foods.

EXPLORE AWESOME SCIENCE EXPERIMENT VIDEOS!

How it Works:

Fats in the foods produce grease spots because fats are nonvolatile. Nonvolatile means that fats have a very high boiling point and do not evaporate easily. In contrast to water, fats that get absorbed by paper cannot get enough heat to evaporate at room temperature. These fats absorbed by the paper are easily visible and make it easy to identify which foods contain fats. 

Make This A Science Project:

Collect a large variety of food samples and hypothesize which ones may or may not contain fats and then use the food fat test to determine the results.

Many people think science is difficult and needs special equipment, but that’s not true.

Science can be explored at home using everyday materials. Everyone, especially children, naturally ask questions about the world around them, and science offers a structured way to find answers.

Misconceptions about the difficulty of science often stem from a lack of exposure to its fun and engaging side. Science can be as simple as observing nature, mixing ingredients or exploring the properties of objects. It’s not just for experts in white coats, but for everyone.

Don’t take my word for it. Below are three experiments that can be done at home with children who are primary school age and older.

Extract DNA from bananas

DNA is all the genetic information inside cells. Every living thing has DNA, including bananas.

Did you know you can extract DNA from banana cells?

What you need: ¼ ripe banana, Ziploc bag, salt, water, washing-up liquid, rubbing alcohol (from a pharmacy), coffee filter paper, stirrer.

What you do:

Place a pinch of salt into about 20ml of water in a cup.

Add the salty water to the Ziploc bag with a quarter of a banana and mash the banana up with the salty water inside the bag, using your hands. Mashing the banana separates out the banana cells. The salty water helps clump the DNA together.

Once the banana is mashed up well, pour the banana and salty water into a coffee filter (you can lay the filter in the cup you used to make the salty water). Filtering removes the big clumps of banana cells.

Once a few ml have filtered out, add a drop of washing-up liquid and swirl gently. Washing-up liquid breaks down the fats in the cell membranes which makes the DNA separate from the other parts of the cell.

Slowly add some rubbing alcohol (about 10ml) to the filtered solution. DNA is insoluble in alcohol, therefore the DNA will clump together away from the alcohol and float, making it easy to see.

DNA will start to precipitate out looking slightly cloudy and stringy. What you’re seeing is thousands of DNA strands – the strands are too small to be seen even with a normal microscope. Scientists use powerful equipment to see individual strands.

Learn how plants ‘drink’ water

What you need: celery stalks (with their leaves), glass or clear cup, water, food dye, camera.

• Fill the glass ¾ full with water and add 10 drops of food dye.
• Place a celery stalk into the glass of coloured water. Take a photograph of the celery.
• For two to three days, photograph the celery at the same time every day. Make sure you take a photograph at the very start of the experiment.

What happens and why?

All plants, such as celery, have vertical tubes that act like a transport system. These narrow tubes draw up water using a phenomenon known as capillarity.

Imagine you have a thin straw and you dip it into a glass of water. Have you ever noticed how the water climbs up the straw a little bit, even though you didn’t suck on it? This is because of capillarity.

In plants, capillarity helps move water from the roots to the leaves. Plants have tiny tubes inside them, like thin straws, called capillaries. The water sticks to the sides of these tubes and climbs up. In your experiment, you will see the food dye in the water make its way to the leaves.

Build a balloon-powered racecar

What you need: tape, scissors, two skewers, cardboard, four bottle caps, one straw, one balloon.

• Cut the cardboard to about 10cm long and 5cm wide. This will form the base of your car.
• Make holes in the centre of four bottle caps. These are your wheels.
• To make the axles insert the wooden skewers through the holes in the cap. You will need to cut the skewers to fit the width of the cardboard base, but leave room for the wheels.
• Secure the wheels to the skewers with tape.
• Attach the axles to the underside of the car base with tape, ensuring the wheels can spin freely.
• Insert a straw into the opening of a balloon and secure it with tape, ensuring there are no air leaks.
• Attach the other end of the straw to the top of the car base, positioning it so the balloon can inflate and deflate towards the back of the car. Secure the straw with tape.
• Inflate the balloon through the straw, pinch the straw to hold the air, place the car on a flat surface, then release the straw.

The inflated balloon stores potential energy when blown up. When the air is released, Newton’s third law of motion kicks into gear: for every action, there is an equal and opposite reaction.

As the air rushes out of the balloon (action), it pushes the car in the opposite direction (reaction). The escaping air propels the car forward, making it move across the surface.

Experiments in food science laboratory manual, introduction: what is food science.

This laboratory manual has two purposes. The first purpose is to describe what food science is and what food scientists do. The second purpose is to describe fun laboratory experiments that demonstrate practical applications of food science. Food science is all of the science involved in taking agricultural food products from the farmer’s gate to the grocery store, restaurant, or dinner table. Food scientists generally work with all sectors of agriculture. Food science includes both basic and applied biology, microbiology, chemistry, math, business, engineering, physics, and other disciplines. A food scientist’s goal is to make safe, high-quality food products that are profitable to all segments of agriculture.

Those who earn a bachelor’s degree in the food science discipline have starting salaries of $45,000 to $55,000 per year and work for some of the largest food manufacturing companies in the country. Food science students also have opportunities to compete in national competitions dealing with food, such as dairy judging, meats judging, new product development, and the Research Chefs Association’s Food Evolution Competition. These events offer participants networking and learning opportunities for future career growth.

It is also possible to pursue a career as a veterinarian through an option in the food science curriculum. This is an excellent opportunity for students interested in veterinary school to work toward an undergraduate degree while completing the pre-veterinary (pre-vet) required curriculum. The veterinary school’s acceptance rate for food science majors is very competitive compared to the acceptance rate for all pre-vet disciplines. However, students with food science backgrounds and degrees who were not accepted to veterinary school still have great job opportunities, making $45,000 to $55,000 a year to start, with room for rapid advancement. Such an annual income and opportunities may not be available to students who graduate from other programs with pre-v et curriculums.

Laboratory exercises in this manual demonstrate principles behind butter making (density, lipid chemistry); cheese production (acid precipitation, protein chemistry); processed meat production (use of salt in meats, protein chemistry); meat marination (use of vacuum in meat processing); sensory evaluation (principles of sensory science: appearance, taste, and smell); candy production (candy chemistry, carbohydrate crystallization); and bread production (bread texture, gluten proteins). These laboratory experiments demonstrate some simple scientific principles that apply to food and explain why and how it is possible to make certain food products.

Experiment 1: Butter

This experiment demonstrates the principles of butter making.

• 1/3 cu p heavy cream
• measuring cups
• clean jar with secure, ti ght-fitting lid
• salt (1/3 teaspo on or to taste)
• Pour 1/3 cup of heavy cream into a clean ja r. Cap the jar.
• Shake the jar. Take turns shaking; you may need to shake for 15 to 20 minutes. The cream will start looking like cottage cheese (whipped cream). Co ntinue shaking.
• You will note a separation of soli ds and liquids.
• The solid is butter, and the liquid is buttermilk.
• Pour off the buttermilk. Add salt to the butter for more flavor. Try the butt er on crackers.

Dairy milk is composed of 87 percent water, 3.2 percent protein, 3.9 percent fat, 4.8 percent carbohydrates, and roughly 1 percent minerals and vitamins. The fat in milk is a mixture of lipids. Triglycerides are the main type of lipid. Lipids have a lower density than water, so when raw milk sits for several hours, the cream (butter) will r ise to the top.

The density of cream is the basis for butter making. The cream is churned to separate the butter (solids) from the buttermilk (liquid). Butter contains at least 80 percent milk fat by weight. The butter can be salted and poured into molds for further processing. Butter remains solid when refrigerated but softens to a spreadable consistency at room temperature and melts to a thin liquid consistency at 90 to 95˚F. Butter is generally pale yellow but can vary from deep yellow to nearly white. The yellow color is the result of the b-carotene in the grass that dairy cows eat.

Homogenizing milk prevents the cream (butterfat) layer from separating from the milk. Homogenizing breaks down the fat beads into smaller beads and disperses them evenly in the milk. The smaller beads will not rise to form cream during normal stor age conditions.

Experiment 2: Casein (Milk Protein)

This experiment demonstrates (1) the precipitation of protein (casein) from milk with an acid (vinegar) and (2) the effectiveness of casein as a bonding agent to mak e casein glue.

• measuring cups and spoons
• 1/4 cup milk
• 400 mi lliliter beaker
• thermometer
• 1 t easpoon vinegar
• cheesecloth
• weigh boats
• 1/2 teaspoon ho usehold ammonia
• wood en craft sticks
• Pour 1/4 cup of milk into a 400 mL beaker. Place stir ba r into beaker.
• Measure the pH of the milk. Place a thermometer in the beaker.
• Heat the milk to 158˚F on a hot plate. Remove the beaker from the heat. Remove t he thermometer.
• Place the beaker with the warm milk on a stir plate and add 1 teaspoon vinegar. Stir for 2 minutes. Allow the milk to sit for a few minutes. The casein will precipitate into heavy white curds. The remaining liqu id is the whey.
• Measure the pH of the liquid portion again.
• Cover the top of the beaker with a piece of cheesecloth. Drain off the vinegar and whey over a sink. Carefully remove the cheesecloth and collect the curds (casein) in the cheesecloth. Rinse the cheesecloth containing the casein in cool water and squeeze the cheesecloth until the casein is almost dry. Spread out the cheesecloth to let the casein dry for a few minutes.
• After drying them, place the curds int o a weigh boat.
• Very carefully add 1/2 teaspoon ammonia solution to the curds. (Caution: ammonia is an irritant.) Slowly stir with a glass rod until the mixture becomes thick and cre amy in texture.
• Rub the casein glue onto two wooden craft sticks and join them together. Allow the glue to dry for a few minutes.

Milk is composed of many proteins. The main groups are casein and whey proteins. Caseins are very digestible when compared to other food proteins, making it a very important human food. Casein is negatively charged in its natural state. This negative charge permits the casein to disperse in milk. When you add an acid, the H+ concentration neutralizes the negatively charged casein. When you acidify milk, its pH is allowed to reach 4.6, which brings casein to its isoelectric point. The isoelectric point is the point at which all charges are neutral. When casein loses its negative charge, it precipitates as curds. This acid casein is the basis for the manufacture of cottage cheese and cream cheese. Acid casein is also used in the chemical industry to produce adhesive products, textiles, and cosmetics, and as a binding agent in food products.

Casein can also be precipitated with rennin, an enzyme found in calves’ stomachs. This rennin coagulum is made of casein, whey protein, fat, lactose, and minerals. It has a fluffier and spongier texture than the acid precipitate. This is the basis for manufa cturing cheese.

Experiment 3: Role of Salt in Meat Processing

This experiment demonstrates the importance of salt in me at processing.

• food pre paration gloves
• food scale that measures in metric units
• 100 grams raw ground beef, divided equally
• small food processor
• 20 milliliters water, divided equally
• 2 grams salt
• large white paper such a s butcher paper
• paper towels

Wear gloves when working with raw meat. Keep meat away from other food products. Wash hands and work station after completing the experiment.

• Place 50 g ground beef into a small food processor.
• Add 10 mL water. Chop the meat for 15 seconds.
• Remove the meat from the food processor. Form it into a ball. Flatten it like you are making a h amburger patty.
• Now, put the slightly flattened meat in the palm of your gloved hand (palm up). Turn your hand over (palm down). What happens? Does the meat stick to your hand, or doe s it fall down?
• Repeat step 1 in this procedure with the other half of the meat. In step 2, dissolve 2 g salt into the 10 mL of water before adding the water to the meat. Follow steps 3 and 4 with t he new mixture.
• Tape a piece of white (butcher) paper to the wall. Place plenty of newspaper on the floor below. Throw the two meat patties at the white paper. Does either one stic k to the paper?

In this experiment, ground meat without salt probably did not stick to your hand or to the target. When you added salt to the ground meat, it made the salt-soluble proteins come to the surface of the meat. In scientific terms, it extracted the salt-soluble proteins from the cellular structure. The proteins then a cted like glue.

Salt serves many purposes. It brings out natural flavors, slows growth of spoilage microorganisms, and enhances a food’s color, odor, and appearance. This experiment shows that salt also creates the protein structure necessary to make processed meats like hot dogs and deli meats. Salt helps bind meat by extracting its proteins, which “glue” together adjacent pieces of meat. Salt also increases water-binding properties, which reduce cook losses—the percentage of weight lost in meat during cooking—and contribute to enhanced texture. It also helps give a smooth, firm texture to processed meats. In addition, it helps with the color development of ham, bacon, hot dogs, and other processed muscle food products.

Did You Know?

Without salt, it would be impossible to make hot dogs, deli meats, and other processed meats. Can y ou explain why?

Experiment 4: Exploding Marshmallows

This experiment demonstrates (1) the principles of air pressure, (2) how changes in air pressure can affect food products, and (3)the principle behind applying a vacuum in m eat processing.

• vacuum pump
• glass jar suitable to be attached to the vacuum pump (The jar should have a rubber stopper with a hole in it to insert a tube. The tube connects to the vacuum pump. You could also use a capped Erlenmeyer flask with a side arm to attach a tube that will connect to th e vacuum pump.)
• marshmallows (d ifferent sizes)
• Place a marshmallow inside the glass jar.
• Cap the jar. Connect the tube from the rubber stopper to t he vacuum pump.
• Turn on the vacuum pump . What happens?
• Turn off the vacuum pump. Wh at happens now?
• Discus s your results.

Variations : You can place several marshmallows inside the glass jar or make a marshmallow man. You can also try expandin g chicken meat.

Marshmallows are a mixture of sugar, air, and gelatin. The sugar makes them sweet, the air makes them fluffy, and the gelatin is a protein that holds everything together. By volume, marshmallows are mostly air. When subjected to vacuum, the air from around the marshmallow is removed. This decrease in pressure causes the air trapped inside the marshmallow to push outward, expanding it. Eventually the vacuum is strong enough to pull air from inside the marshmallow, causing it to shrink. When the air in the jar returns to normal atmospheric pressure, you end up with a “mallow grape” because the air has been removed from inside t he marshmallow.

This same principle is used in the meat and poultry industry to marinate chicken and other pre-marinated meats. Vacuum meat tumblers marinate meat in a very short time. Under vacuum, the foods’ fibers stretch, becoming more porous. This allows the marinade to penetrate evenly throughout the product. Vacuum tumbling allows meat to absorb up to about 20 percent of its starting weight in marinade without extended preparation. There is an increased yield in the raw product, which means increased yield after cooking and a product that is j uicy and tasty.

Experiment 5: Food Flavors

This experiment demonstrates how appearance influences our perception of ho w foods taste.

Sports Drink Materials

• small sampling cups with lids (2 oz size is ideal)
• sports drinks (lemon-lime and orange flavors)
• re d food coloring
• Add a few drops of red food coloring to the lemon-lime flavored sports drink. Mix until the color resembles the orange of orange-flavore d sports drink.
• Pour the two orange-colored sports drinks, lemon-lime and orange, into sampling cups. Label each cup using a code to identify each type of drink.
• Give student s both samples.
• Ask students to pinch their noses and taste each sports drink sample. Recor d the response.
• Ask students to release their noses and taste each sports drink sample. Recor d the response.

Soft Drink Materials

• Sprite or o ther clear soda
• Coca-Cola or o ther brown cola
• caramel color
• Add a few drops of caramel color to Sprite until the color is similar t o that of Coke.
• Pour both drinks (Coke and colored Sprite) into labeled sampling cups. Each cup should have a code to iden tify its drink.
• Provide students wit h both samples.
• Ask students to pinch their noses and taste each soda sample. Recor d the response.
• Ask students to release their noses and taste each soda sample. Recor d the response.

Variation : If you cannot find caramel color, you can try a red-colored soda like cherry and an unflavored clear soda like club soda or seltzer water. Add a few drops of red color to the clear soda until it looks like the red soda, pour the sodas into the sampling cups, and ask the students to tas te both drinks.

Most of the time we assume things about a food’s flavor based on its color. Changing the color of a lemon-lime sports drink can makes it look like the orange-flavored sports drink, but it still tastes like lemon lime. However, your mind can play tricks on you and convince you that it is orange flavored. Similarly, the color of Sprite is changed so it looks like Coke, but it does not t aste like Coke.

Experiment 6: Determining Flavor with Your Nose?

This experiment demonstrates how your mouth and nose work together to perceive diff erent flavors.

• jelly beans of d ifferent colors
• smal l sampling cups
• Place two jelly beans of the same color in th e sampling cup.
• Ask a student to pinch their nose and taste a jelly bean from the cup. Recor d the response.
• Ask the student to release their nose and taste another jelly bean from the same cup. Recor d the response.

You cannot determine flavor without your nose. Without the sense of smell, foods would not be tasty. You would not be able to tell the difference between foods with the same texture. A food’s odor allow us to determine its flavor. About 80 to 90 percent of what we perceive as “taste” is actually due to the sense of smell. This is why foods taste bland when you have a cold or a stuffy nose.

There are four different types of true tastes: sour, sweet, salty, and bitter. The salty/sweet taste buds are near the front of the tongue, the sour taste buds line the sides of the tongue, and the bitter taste buds are at the very back of the tongue. Children are very sensitive to the flavors in foods. As people age, their taste buds become less sensitive.

Experiment 7: Candy Making (Hard-Crack Stage, 300˚F)

This experiment demonstrates (1) the chemistry of candy making and (2) the effect of temperature on the textu re of candies.

• shallow baking p an (8x8x2 inch)
• heavy dut y aluminum foil
• 435 grams (about 2 1/8 cups) sugar
• 1/2 cup l ight corn syrup
• 1/2 cup water
• 2-quart saucepan or 1,000 mL beaker
• ca ndy thermometer
• stove (for saucepan) or hot pla te (for beaker)
• food coloring
• 1/2 teaspoo n oil flavoring
• Line an 8x8x2-inch pan with heavy duty aluminum foil, extending foil over the edges of the pan. Oil t he pan lightly.
• Combine sugar, corn syrup, and water in a 2-quart saucepan or a 1,000 mL beaker. Place a candy thermometer in the pan. The thermometer should not touch the bottom of the pan or beaker. Stir the mixture over high heat until it boils.
• Reduce heat to medium. Continue cooking over medium heat. Do not stir the mixture while it is cooking. When the syrup reaches 260˚F, add food coloring. Do not stir; boiling action will incorporate color into the syrup. Remove from heat precisely at 300˚F. Remo ve thermometer.
• Once boiling has stopped, add flavoring. Pour syrup quickly but carefully into prepared pan. ( Caution: mixture is very hot .) Let it stand for 5 minutes.
• Using a broad spatula, mark candy surface in 1/2 inch squares. Retrace previous lines and press the spatula deeper each time until you can press the spatula to the bot tom of the pan.
• Cool completely. Use foil to lift candy out of the pan. Break candy into squares and store i n plastic bags .

Variation : You can use plastic molds for hard candy or lollipops. Lightly oil the molds before pouring the hot mixture. Twist the lollipop stick to make sure it is covered with the syrup. Let lollipops cool until hardened before remov ing from molds.

Sucrose, or table sugar, and other sugars are the main ingredients in candy. Sucrose is made of two simple sugars, glucose and fructose, that are bound together. Sugar crystals are solid at room temperature. When sugar crystals are dissolved in water, the sugar goes into solution. At a particular temperature, water can dissolve only a certain amount of a particular sugar. The solution reaches the point where no more sugar can be dissolved, and extra sugar will just sink to the bottom. This point is called the sat uration point.

Heating the sugar/water solution increases the amount of sugar that can be dissolved. The heat causes the crystals to break into smaller molecules. The sugar molecules move faster and farther apart, enabling the solution to dissolve more and more sugar molecules. The solution turns into a clear sugar syrup. As you add more sugar, the solution becomes super-saturated. This means that the solution has reached a delicate balance of just enough sugar molecules and enough heat to keep the sugar molecules dissolved, but in an unstable state. The sugar molecules begin to crystallize back into a solid at the least disruption of heat or action. In other words, the sugar comes back together as sugar crystals when th e syrup cools.

To make candy, you boil a mixture of sugar and water to create sugar syrup. The water evaporates, and the sugar concentrates. The higher the temperature, the more concentrated the sugar becomes. The texture of a candy (hard, soft, or chewy) depends on its cooking temperature and ingredien ts (Table 1).

Experiment 8: Gluten

This experiment demonstrates (1) what gluten is, (2) its importance in bread making, and (3) its presence in all- purpose flour.

• mixing bowls
• measuring c ups and spoons
• 1/2 cup + 2 teaspoons al l-purpose flour
• 1/ 2 cup soy flour
• 1/2 cup water, divided
• Measure 1/2 cup of soy flour into a bowl. Measure 1/2 cup of all-purpose flour into a different bowl.
• Add 1/4 cup of water to each bowl of flour and mix.
• If the all-purpose flour mixture is sticky, add up to 2 teaspoons of additional flour, 1 teaspoon at a time. Mix and knead after each flour addition. Do not add flour to the soy flour mixture.
• Knead dough mixtures for about 5 minutes each. Note texture, appearance, color, elasticity, and flexibility of each dough ball. The soy flour dough looks clumpy, yellowish, and has no elasticity. Why? The all-purpose flour is opaque, elastic , and flexible.
• Place the all-purpose dough ball under the faucet and run cool water over it. Squeeze the dough ball to drain white, starchy water. Continue doing this under running water for about 5 minutes. What happened? Note how the dough shrinks in size, changes color, and becomes thread-like. These are the gluten threads. The water that drains from the dough ball is white as the starch is washed out of the dough ball.

Gluten is a protein found in wheat, rye, and barley. All breads made with wheat flour have a certain amount of gluten, depending on the type of flour. For example, cake flour has the lowest amount of gluten (5 to 8 percent), while high-gluten flour has greater than 14 percent. All-purpose flour is 11 to 12 percent gluten.

Gluten is the substance that gives bread its structure, texture, and elasticity. Gluten is made up of two main groups of proteins: gliadins and glutenins. Without these proteins, it would not be possible to make bread with an acceptable texture. Gluten is developed in the dough when gliadins and glutenins absorb water and are pulled and stretched in the kneading process. As the proteins are worked, they become long, flexible strands. The yeast produces gases in the dough, mostly carbon dioxide. These strands trap the gas bubbles, and the dough rises befo re it is baked.

Without gluten, bread would be very dense or flat. Rice, potato, and oat flours do not have gluten, and bread made from these flours does not turn out well.

Some people are unable to eat gluten because of either a wheat allergy or celiac disease. Gluten causes damage to the intestines and stomach of a person with celiac disease.

Space beer may taste better than Earth beer

By Andrew Paul

Posted on Aug 16, 2024 1:19 PM EDT

4 minute read

Researchers are investigating how beer making may be affected by microgravity—not (just) for the prospect of one day sipping brews in space, but for ensuring humanity’s survival beyond Earth.

Virtually every civilization throughout history has relied on fermentation not just for their booze, but for making everything from bread, to pickles, to yogurt. As humanity’s technological knowledge expanded, we have adapted those same chemistry principles to pharmaceuticals and biofuels, among many other uses. And while it may not be the first necessity that comes to mind when planning for long-term living in a lunar base, or even on Mars, the process will be crucial to long-term mission success.

To explore how these concepts may change offworld, a team at the University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) first experimented with making beer in microgravity. Their results, published in the journal Beverages , indicate microgravity may not only speed up fermentation processes—it may also produce higher quality products.

“We are absolutely going to be conducting fermentations under microgravity in the future, as we continue space exploration, and there are going to be outcomes that will be very difficult for us to predict,” Andrew MacIntosh, study co-author and UF/IFAS associate professor of food science, said in an accompanying university announcement on August 14.

Getting a beer brewer’s starter kit up to the International Space Station, however, isn’t quite in the cards yet. Instead, the UF team led by undergraduate researcher Pedro Fernandez Mendoza created a tiny microgravity simulator here on Earth. After gathering locally grown barley and mashing it into wort (grain-derived sugary liquid necessary for beers and whiskey), Mendoza and colleagues portioned it out into six samples. They then added the yeast used in lagers , Saccharomyces pastrorianus , to each tube before leaving three of them to act as controls. The other trio were placed in a clinostat—a tool capable of simulating microgravity conditions by constantly rotating its contents around a horizontal axis. Over the course of three days, the team then assessed their fermenting baby-beers at regular intervals on the basis of density, yeast counts, and yeast viability.

After three days, researchers were able to confirm one of their initial hypotheses that microgravity doesn’t appear to harmfully affect fermentation. What’s more, the fermentation process actually sped up in the clinostat samples as compared to their controls. But there was one additional, unexpected result—microgravity yeast may allow for even higher quality products than simply fermenting here on Earth. Although further investigation is needed, researchers think this might relate to a particular gene in yeast that oversees the levels of ester—fermentation byproducts responsible for both good and bad beer flavors.

[Related: The science and history of the evolution of lager .]

Typically, the ratio between high alcohol groups and lager ester amounts ranges between 3-4:1, with higher ratios offering a drier, less aromatic beer. The team recorded their control samples as having a ratio of 1.4:1, while their microgravity beer measured 4.6:1, implying the latter was “less aromatic by this measure.”  Meanwhile, two esters in particular, isoamyl acetate and 2-phenethyl acetate, showed “significant differences” between microgravity and controls. Higher concentrations of these esters produce a fruity, banana-like flavor in beers that many drinkers often consider undesirable. In the microgravity brews, a “multiple-fold decrease” in ester concentration compared to the standard examples.

“Depending upon the brewery, these compounds may be desirable; however, the presence of these compounds above a detection threshold would usually be considered a defect,” the team writes. Given this, their microgravity results offered a final product  “that would be considered higher quality due to the reduced esters.

As for brewing in space, researchers now believe microgravity may actively help things along to create better beers, and may even “provide benefits not realized terrestrially.” MacIntosh and his team, however, can’t attest to any potential benefits just yet—they didn’t try their concoctions.

“Unfortunately when we make beer for science we use rather boring recipes,” he tells Popular Science while making sure to note “there are a few local collaborators who make very decent quality beer upon whom we rely for quality when it is deemed necessary…”

Japan Is the World’s No. 1 Hotspot for UFO Sightings. Officials Are Trying to Figure Out Why.

Are the reports really about aliens or could a national security threat be at play?

Throughout the 1970s, residents in and around the town of Iino, near Senganmori Mountain, began reporting frequent sightings that they credit to the region’s spiritual and magnetic forces. The town’s location in Fukushima Prefecture has continued to draw more UFO attention, especially over the last decade. In fact, a rash of recent UFO sightings in Japan have occurred around nuclear facilities. Online forums and YouTube accounts are stacked with descriptions and videos of moving lights and clustered Unidentified Anomalous Phenomena (the modern-day term for a UFO) in the skies over Fukushima following the nuclear disaster there in 2011.

When strange UAP reports begin to pour in from a country’s nuclear or defense facilities, it seems governments start to take the threat more seriously.

Japanese officials met on May 28, 2024 to announce the formation of an 80-plus-member, bipartisan look into increased UAP sightings within the country, especially in the Fukushima region. The new investigative body comes on the heels of last year’s U.S. Navy disclosures—detailing pilots’ accounts of aircraft capable of impossible maneuvers—and Congressional investigations into those reports. As a result, the U.S. Department of Defense created the All-Domain Anomaly Resolution Office (AARO) in July 2022 to trigger a more serious look into the threats UAPs may pose.

Similarly, Japan’s response to ongoing sightings in the Land of the Rising Sun demonstrate how those lights in the sky are now considered legitimate national security threats, worthy of official mainstream investigation. But that doesn’t mean it will be easy to uncover the truth.

Aliens, Drones, Birds, or Myths?

Avi Loeb, Ph.D., is a physicist and professor at Harvard University. In a landscape where people make up their minds about UAP incidents before a proper investigation, Loeb applauds the Japanese approach of looking at its sightings from a more serious perspective.

“In the UAP field, there are skeptics and there are believers,” Loeb says. “Unfortunately, none of them are doing the hard work. That’s why it’s important to see government efforts such as AARO and this body in Japan approach UAPs objectively. In both cases, they’re considering possible security threats, but they’re not trying to debunk them.”

Loeb understands that citizens reporting UAP sightings in Japan, the U.S., or elsewhere most likely want to believe that they’re spotting extraterrestrial spacecraft. However, official efforts emerging from Japan and the Department of Defense must consider every possible explanation.

“I lead the Galileo Project at Harvard [the systematic scientific search for evidence of extraterrestrial technological artifacts],” Loeb explains. “In our work, we must first consider if an object is naturally occurring like a meteor or a bird, or if it’s human-made like a drone or a balloon . I think that is the approach these government agencies must take.”

As for why Japan has become a recent hotbed for UAP activity, the human psychology of mass hysteria and confirmation bias could play a role.

Mick West is a science writer with the Center of Inquiry, an Amherst, New York-based organization that investigates pseudoscience. He took a look at the Japanese claims of UAPs around Fukushima and would credit the decade’s worth of reports to people watching the area and wanting to get in on the proverbial UFO flap.

“We see a lot of videos and reports coming out of Fukushima because it’s a world famous site of a nuclear plant disaster,” says West, who has analyzed hundreds of UAP sightings. “There are a lot of 24/7 webcams around the power station. It’s natural for there to be more eyes looking at the area, and it’s likely those webcams are occasionally going to capture something people can’t identify such as a bird or an airplane. Once the public reports any of those images or videos as a UFO, people start going back looking for more images and videos to report as UFOs.”

As for Japan’s ongoing status as a UAP hotbed, West credits the clustering of reports to the true believers wanting to participate in the action or translating local superstitions into alien legends.

“You also see a town like Kofu wanting to brand itself as the Japanese Roswell to boost tourism,” West adds, drawing a comparison to the small New Mexico town that built international fame out of media reports of a crashed flying saucer in 1947.

It does seem possible that Japan’s myths, legends, and rich narrative tradition could be driving the suggestion of UAP reports, according to Joshua Frydman, Ph.D., an associate professor of Japanese at the University of Oklahoma who also wrote The Japanese Myths: A Guide to Gods, Heroes and Spirits in 2022. He says the foundational tales of eras past can inspire everything from pop culture trends to new faiths to the latest craze—and UAPs can easily fall into any of those categories.

“Ancient mythology is not only deeply incorporated into popular culture, but actively known and discussed in popular books, including ones on ‘secrets’ of being Japanese,” Frydman explains. “It’s also the foundation of several ‘new religions’ or the Japanese idea of cults, like the one responsible for the sarin gas attacks by Aum Shinrikyo on the Tokyo subways in 1995.”

Frydman notes that the influence of centuries-old stories on Japanese culture is somewhat recent as he claims it was not known as widely before the 1890s. He paints a portrait of an ancient society struggling to incorporate a late-hour introduction of the past’s mythology—while driving much of the world’s 20th- and 21st-century technological evolution.

“The current widespread knowledge of the ancient myths is related to the pre-World War II government’s attempt to make Shinto into a modern national religion by teaching the myths as actual history in schools,” he adds.

A Matter of Science and National Security

Given that the Japanese Parliament’s early summer announcement of its new UAP probe followed right on the heels of America’s creation of AARO, it might seem that the U.S. applied a form of international peer pressure to make UAP investigations a global effort.

However, Loeb believes potential threats from nations like China and North Korea have actually forced Japan and the U.S. into this position.

“Obviously, confirming extraterrestrial intelligence would be massively important for science as it would prove that we’re not alone,” Loeb explains. “But, importantly for national security, it’s essential for officials to admit we need to know what these objects are. In the case of Japan, there are nearby countries who want to spy on that nation. That government needs to know if they’re spotting drones or other devices used for espionage.”

As UAP investigations become a matter of public record in the U.S., Japan, and elsewhere, the PBS series NOVA will dig into the international question of UAPs in the upcoming January 2025 program, “What Are UFOs?” Julia Cort and Chris Schmidt, co-executive producers on the project, agree that efforts around the world to study the nature of UAPs will help to move the field beyond folklore or hype—and perhaps truly make some discoveries.

“It’s not just a question of what’s happening in Japan or the U.S. with these new official investigations,” Cort says. “This is a topic so many people are curious about, and the time is right to tackle it because the tone of the examinations and discussions around it have changed. There’s different kinds of evidence now, and it’s being taken more seriously.”

Schmidt hopes that UAP policy developments don’t become the main focus of what’s really going on in our skies.

“It’s important to look at what science can tell us about what [UAPs] are, rather than watch what defense departments are doing about them,” Schmidt says. “If any of us anywhere in the world see something they can’t explain or read a report about a sighting, there are questions we can ask to wrap our heads around possible explanations.”

Back in Japan, as the new UAP investigative body ramps up, the current government’s opposition leader, Yoshiharu Asakawa, went on the record opposing any concept of serious study on the topic. Via interpreted reports, he called UAPs “an occult matter that has nothing to do with politics.”

However, investigation member and former defense minister Yasukazu Hamada echoed the thoughts of Loeb and other scientists, insisting both national security and scientific exploration make UAP studies essential.

“It is extremely irresponsible of us to be resigned to the fact that something is unknowable and to keep turning a blind eye to the unidentified,” Hamada said.

High-pressure processing (HPP) is recognized by the United States Department of Agriculture Food Safety and Inspection Service (USDA FSIS) as a post-lethality treatment to control Listeria monocytogenes in ready-to-eat (RTE) meat and poultry products. A scoping review of 603 journal articles, which ultimately was narrowed down to 16 articles, revealed that the efficacy of HPP varies with fat content. The studies demonstrated that L . monocytogenes inactivation by HPP tends to be lower in RTE meats with greater than 5% fat content, compared to products with lower than 5% fat. The wide range of HPP parameters used in these studies have made it challenging to estimate fat’s baroprotective effects. However, building on the results of the scoping review, an experiment was designed and conducted to assess the impact of fat content (5, 15 and 25%) and pressure levels (300, 450 and 600 MPa) on the inactivation of L . innocua in emulsified pork sausages. Two L . innocua strains were used to inoculate the samples, which were then treated with HPP at 18 °C for 3 min. Microbial counts were assessed using direct plate counts on TSYEA after incubation at 32 °C for 48 h. The results showed significant differences ( p p > 0.05), while at 600 MPa, L . innocua was reduced to below detectable levels in all samples. Three polynomial models were developed. Results showed there was a significant interaction between fat content and pressure and the model with the main and interaction effects, log 10 ( N 0 /N P ) F = β 0 + β 1 F + β 2 P + β 3 FP , had an adjusted coefficient of correlation ( R 2 adj ) and root mean square error ( RMSE ) of 0.971 and 0.365 log reduction. The bias factor ( B f ) after cross-validation showed this model is fail-safe. Its accuracy factor ( A f ) was 1.434, suggesting more data are needed to develop a robust model for practical application.

New climate and sustainability research efforts will focus on eight ‘Solution Areas’

The Stanford Doerr School of Sustainability will establish new research initiatives under topics including climate, water, energy, food, nature, and cities.

The Stanford Doerr School of Sustainability has selected eight interconnected Solution Areas to focus its research efforts over the next decade. This new research plan amplifies the school’s ability to translate Stanford research into large-scale solutions and inform key decision makers in policy and business.

Selected based on extensive faculty input and assessment of where Stanford can make the most meaningful impact, the eight areas are: climate; water; energy; food; risk, resilience, and adaptation; nature; cities; and platforms and tools for monitoring and decision making. 

“Solution Areas identify and leverage the critical junctions between the most pressing global sustainability challenges and the areas where Stanford has the talent and expertise to find solutions,” said Dean Arun Majumdar. “This collaborative all-campus approach expands and strengthens our commitment to using all the power we have – the knowledge, the education, the talent, the innovation, the resources, the influence – to build a thriving planet for future generations.” 

‘Integrative Projects’ and ‘Flagship Destinations’

In each Solution Area, the school plans to build two types of research initiatives. One type, called Integrative Projects, will be managed by the school’s institutes, including the Stanford Woods Institute for the Environment , the Precourt Institute for Energy , and a planned Sustainable Societies Institute. 

Integrative Projects will be organized around decade-long research themes and dedicated to creating solutions through interdisciplinary collaboration, engagement with partners beyond Stanford, identifying significant knowledge gaps, and understanding systems.

According to Chris Field , the Perry L. McCarty Director of the Stanford Woods Institute for the Environment and a professor in the Stanford Doerr School of Sustainability and the School of Humanities and Sciences , the new commitment to these areas “will provide both resources and coordination that expand Stanford faculty’s capacity to deliver sustainability solutions at scale.” 

A second type of research initiative, called Flagship Destinations, is managed by Stanford’s Sustainability Accelerator . Flagship Destinations are targets for the pace and scale of work to address challenges facing Earth, climate, and society. For example, the school’s first Flagship Destination, announced in 2023 , calls for enabling the removal of billions of tons of planet-warming gases annually from Earth’s atmosphere by the middle of this century. By working backward from sustainability targets in consultation with faculty and external experts, this initiative seeks to rapidly translate Stanford research into policy and technology solutions. Additional Flagship Destinations will be announced later this week.

Whereas Integrative Projects are designed to produce knowledge and evidence that can eventually lead to solutions, Flagship Destination projects are intended to help verify and demonstrate that well-studied solutions can succeed at large scale so they can be launched out of Stanford and implemented for the benefit of humanity and our planet. Scalable solutions nurtured and launched through these projects could take the form of policy frameworks, open-source platforms, nonprofit organizations, new for-profit companies, and ongoing collaborations all committed to addressing pressing sustainability challenges.

“By working together in these Solution Areas across disciplines and with collaborators beyond the university, we maximize our ability to have positive impacts on the timeframe and scale needed for the planet and humanity,” said Scott Fendorf , senior associate dean for integrative initiatives and the Terry Huffington Professor in the Stanford Doerr School of Sustainability. 

Workshops will be held with faculty and external experts to develop research strategies for each Solution Area on a rolling basis. Strategy workshops, opportunities to provide input on future Integrative Projects, and requests for proposals (open to all Stanford faculty) will be announced in the coming months.
