Biology Science Fair Projects for 10th Grade – Pique Your Students’ Interests

By the time that children reach 10th grade, they’ve usually begun to develop their own unique interests and academic preferences. That’s why we came up with a list of fun and engaging biology science fair projects for 10th grade students tailored towards a variety of different interests – whether your student is an environmental expert or a budding behaviorist, we’ve got you covered!

Related post: Simple Science Fair Projects for 3rd Grade

Environmental Experts

Does soil in your neighborhood contain high levels of lead.

Lead is a chemical element that occurs naturally in the environment including air, water, and soil. In large enough amounts, lead is also toxic to humans. While the government has made great efforts in the last several decades to reduce the amount of lead exposure among humans, lead still remains in our environments. Although lead generally occurs in low enough amounts that it does not negatively affect our health. 

In this project, students will be required to test lead levels in soil samples around their neighborhood or community. This is to determine if and where high levels of lead exist. To test soil samples, students will need a lead soil test kit. Kits can be purchased from the Carolina Biological Supply Company (item #181805). 

Before beginning the project, students should conduct background research into what levels of lead are considered safe and what levels are considered dangerous. Then, they can develop hypotheses regarding where they think the highest levels of lead will be found and what those levels will be. Finally, they can test soil samples taken from different areas in their neighborhood and compare their results to their original hypotheses.

Budding Behaviorists

Do betta fish habituate to repeated presentation of aggression-inducing stimuli.

This is a great project for a student who already has a betta fish as a pet, or for a student who has been begging to get one! For this project, all you need is a betta fish and a mirror. Betta fish can be purchased at your local pet store.

Betta fish are known to be aggressive fish, which is why they tend to be kept alone as pets. When these fish encounter another betta fish, they demonstrate an aggressive response. To experience this aggression response for yourself, you can place a mirror in front of a betta fish’s bowl to “trick” the fish into thinking it is looking at another fish. 

Many animals demonstrate a phenomenon known as habituation. Habituation refers to the reduction of a behavioral response to a stimulus following repeated presentations of that stimulus. For example, if I stand behind you and unexpectedly shout your name, you will likely demonstrate a startle response (e.g., jumping, screaming, or flinching). However, if I stand behind you and shout your name ten times in a row, by the tenth time, you will likely stop demonstrating a startle response. This process is known as habituation.

In this project, students are required to examine whether the betta fish demonstrates habituation to repeated exposure to a threatening stimulus by being presented with “another fish” by using a mirror.

For starters, students should come up with a set of testable hypotheses like the following: What do they think the aggressive response will look like? How many times can they place the mirror in front of the bowl until the betta fish stops showing aggressiveness? How long will habituation last if, for example, the fish habituates and then is left alone overnight? Will it demonstrate an aggressive response when the mirror is placed in front of the bowl again the following morning?

Does reaction time differ across genders? Does it differ across age groups?

This project is an easy one that requires a ruler. To test human reaction time, students should come in pairs. The “subject” will be tasked to hold his/her hand out with a gap between their thumb and index finger. The other should then hold a ruler above the gap in the subject’s hand with the “0” marking on the ruler lined up with the top of their hand. Then, the said student should drop the ruler without saying when they will drop it, and have the subject pinch their thumb and index finger together to catch the ruler. Take note of the number located at the top of the subject’s thumb. Now, t o get an average reaction time measure, the students should repeat this at least five times.

To calculate the reaction time, students will need to convert the numbers recorded from the ruler to reaction times using this table . Students can then get the results based on the trials they’ve gone through to calculate an average reaction time for the subject. After this, students can test females and males to determine if there are any differences in reaction time across genders. Alternatively, they can test people of different ages. 

Botany Buffs

How important are soil microorganisms for plant health.

For some of your students who have green thumbs, this science fair project will be perfect for them. In this project, they will need to examine the importance of microorganisms in plants by testing different rates of plant growth among plants grown in sterile versus non-sterile soil.

Heat is known to kill microorganisms in the soil. So keeping that in mind, students can then examine the importance of soil microorganisms by comparing growth among plants grown in soil that has been heat sterilized in the oven and soil that has not been heat sterilized. 

While the basic premise of this project is simple, it’ll also be a great opportunity for students to develop and test their own hypotheses. For example, students can test what temperature is most effective at killing microorganisms in the soil by placing different soil samples in the oven at different temperatures. Other possibilities include testing the effect of sterilization on different types of plants or adding other organisms, such as worms, to the soil. 

DNA Devotees

Which animals have their genomes sequenced.

Although hands-on experiments make for great science fair projects, secondary research can serve as an excellent low-budget alternative. Secondary research refers to compiling and summarizing already existing data – and all you need for it is a computer with internet access.

One interesting topic for secondary research is genome sequencing. Genome sequencing refers to the process of figuring out the order of all the thousands of nucleotides that make up an organism’s DNA.

For this project, students can gather information simply by searching through Google. Alternatively, the government also provides easily searchable databases containing a wealth of information on sequenced genomes. For example, the National Center for Biotechnology Information provides an easy-to-search genome sequence database .

To search this database, simply enter an animal’s common name (e.g. “dog”) and hit enter to search. Have your student put together a data table that includes genome sequencing details for each animal.

Frequently Asked Questions

I have budget restrictions. what projects can my student do for free.

Secondary research (described in the DNA section above) is a perfect no-cost option for a science fair project where your students would only need a computer with internet access. If they don’t have one at home, they can visit the school’s computer room or use the computers available local library (provided that their library has a makerspace ).

How to Choose Science Fair Projects

The hardest part of a science fair project can be getting started, so check out these steps!

• Think about what is interesting to you. Do you love food? Are you obsessed with cats or dogs? Are you curious about soil? You’ll find a wide range of fun topic ideas for your science fair on this list. 
• Pick a topic or project idea from this list.
• Brainstorm questions  about the topic. Check out this resource via Science Buddies . 
• Turn your idea into a science fair project . Steve Spangler Science explains that there are three steps for turning an experiment or demonstration into a science fair project. Once you find an idea you like, you must change something about it. Then, create  a new experiment. Finally, compare  results!
• Use the scientific method for kids to make sure you cover all the important parts of your chosen science fair project…

How to turn your Science Idea into Cool Science Fair Projects

Some of the ideas in this post are demonstrations  that you can turn into projects.

For example, consider making your own fire extinguisher . We know that baking soda and vinegar deprives fire of oxygen. This is what puts the fire out.

• Change  the ratio of baking soda to vinegar to  create  a new experiment and compare  results.
• Or see what changes  you can make to to cause your fire extinguisher to shoot the farthest . 

Make a Science Fair Poster

The next step is to create a science fair board or poster to present your project. This is an important step because it is the way you communicate your great ideas to those who will be attending the science fair…and judging it!

Tips for Easy Science Fair Projects

• Don’t overthink this! Start with a simple concept and explore it thoroughly.
• It is OK to choose a favorite project and add a twist or explore an additional angle.
• Demonstrate your project with bold images or a demonstration.
• Show results through a demonstration.
• Use your other talents. If you are an artist, integrate that. If you are interested in a certain subject, choose a project that shows it!

What are the top 10 science fair projects?

These are the traditional tried and true science projects that show up at every science fair…for a reason!

• Lemon or potato battery
• Homemade volcano

12 Award Winning Science Projects for 10th Graders

Published on march 8, 2018 at 7:58 am by sieni kimalainen in lists.

Here we are to find out which some award winning science projects for 10th graders are. If you’re out of ideas, we hope that you’ll pick something of the interest for you from the list.

So, you are a fresh high-schooler with huge ambitions, and science is the field you want to try yourself out. That’s great. But before considering award winning science fair projects for high school, you should first get some guidelines for conducting your project.

But if you already have experience from before, with award winning science fair projects for 9 th grade, then you can skip this introduction, because you are probably familiar with the topic. But, nevertheless, as the ancient Romans used to say – repetitio est mater studiorum (repetition is the mother of learning) it is not bad idea to go through it once more.

Anyway, starting any science fair projects means thinking about it in general, and the first thing is, of course, choosing your field of interest, whether it is any particular field of biology, physics, earth sciences or whatever else. For a winning science project, you should also pay attention to current hot topics in science (if, you are not a genius which can think of something revolutionary, which is not impossible either). Such topics include environmental issues, health issues, resolving problems of pollution, food, but also some things that would make everyday life easier. Now when you have gotten your topic the first thing you should think about is making of a hypothesis: why you are doing this particular thing, why is it important, in which way does it help the science? A good and cogent hypothesis actually helps a lot; both with making your task clear to yourself and making it interesting and clear to the audience.

Next steps include (depending on the topic of course) preparing and making the experiment and/or gathering the data, analysis, and a conclusion or a resulting product in the end. Sounds easy, but it does not necessarily need to be (once again depending on the subject you have chosen). But, no need to worry, that’s why you have here examples of the award  winning science projects for 10 th graders that will be your guide for a good experimentation procedure and other steps of your project.

Anyway, from this very short introduction on the basics of scientific research, we go closer to our list. There were plenty of places where we got really interesting ideas on science projects, and the info on which the award winning science fair projects for 10 th graders are. These were, among others, Education , Science Project Resources , Julian’s Science Fair , All Science Projects , and   Home Science Tools (psst, if you are too lazy there are some last-minute fair project ideas you can check out on this website). It was a hard choice, in the end, making a proper list for the award winning science projects for 10 th graders, but from all the suggestions we have tried to pick the best ones and cover as much scientific fields as possible. But in the end, if you are going to win an award with your project or not, depends mostly on your effort. You can also check 10 Winning Science Fair Projects for High School for high school in general, not only for 10 th graders, including 11th grade science fair projects or science fair projects grade 12 for example.

And in the end just one more thing. These 10th grade science fair projects are project examples of already existing ones. Instead of copying them, you should rather use them as guidelines and ideas for something of your own and original. Think about them as an inspiration, and let’s see which those award winning science projects for 10 th graders are:

12. What is the better method of learning: reading or listening?

Field: psychology

This is an interesting topic that people often are puzzled about. And in the end, there are opinions that some people are just better at reading and observing while others are better learners by listening. Well, in this project you are going to debunk some myths.

Browse hundreds of science fair project ideas to find the ideal project according to grade level.  Preschool Science Project Ideas Preschool is not too early to introduce children to science! Most preschool science ideas aim to interest kids in exploring and asking questions about the world around them. Play with silly putty and examine its properties. Look at flowers. How many petals does each flower have? What parts do flowers share in common? Blow up balloons. What happens when you release an open balloon? What happens when you rub a balloon on your hair? Explore color with fingerpaints. Blow bubbles and look at how bubbles interact with each other. Make a telephone with cups or cans and some string. Have preschoolers categorize objects into groups. Discuss similarities and differences between objects. Grade School Science Project Ideas Students are introduced to the scientific method in grade school and learn how to propose a hypothesis . Grade school science projects tend to be quick to complete and should be fun for the student and the teacher or parent. Examples of suitable project ideas include: Determine whether insects are attracted to lights at night because of their heat or their light. Does the type of liquid (e.g., water, milk, cola) affect seed germination? Does the power setting of the microwave affect how many unpopped kernels are in popcorn? What happens if you pour a liquid other than water through a pitcher-type water filter? What type of bubble gum produces the biggest bubbles? Middle School Science Fair Ideas Middle school is where kids can truly shine at the science fair! Kids should try to come up with their own project ideas, based on topics that interest them. Parents and teachers may still need to help with posters and presentations, but middle school students should have control of the project. Examples of middle school science fair ideas include: Examine food labels. How does the nutritional data for different brands of the same food (e.g., microwave popcorn) compare? Is laundry detergent effective if you use less than the recommended amount? How permanent are permanent markers? Are there chemicals that will remove the ink? Can a saturated solution of salt still dissolve sugar? Do green bags really preserve food longer? Are goldfish water chemicals really necessary? What shape of ice cube melts the slowest? High School Science Fair Ideas High school science fair projects can be about more than a grade . Winning a high school science fair can net some nice cash prizes, scholarships, and college/career opportunities. While it's fine for an elementary or middle school project to take hours or a weekend to complete, most high school projects run longer. High school projects typically identify and solve problems, offer new models, or describe inventions. Here are some sample project ideas: Which natural mosquito repellents are most effective? Which home hair color holds its color through the most washings? Do people who play car racing video games have more speeding tickets? Which high school sport is associated with the most injuries? What percentage of left-handed people use a computer mouse with their left hand? What season is worst for allergies and why? College Science Fair Ideas Just as a good high school idea can pave the way for cash and college education, a good college project can open the door to graduate school and gainful employment. A college project is a professional-level project that shows you understand how to apply the scientific method to model a phenomenon or answer a significant question. The big focus on these projects is on originality, so while you might build on a project idea, don't just use one someone else has already done. It's fine to use an old project and come up with a new approach or different way of asking the question. Here are some starting points for your research: What plants can detoxify gray water flowing from a home? How could the timing of a traffic light be changed to improve intersection safety. Which home appliances use the most power? How could that energy be conserved?

Have you begun the arduous task of looking for  science fair projects  that might pique your child’s interest? Or do you have a child who already has ten ideas they have been dying to try? The science fair is a great school tradition and a memorable experience for many children (I still remember the life size plaster penguin I made in 5th grade), and if your school doesn’t conduct one, consider starting it! This year if you are on the lookout for science fair projects I challenge you to think beyond the vinegar volcano (we have “Volcano Alley” at our school because there are so many volcano projects every year). I know, vinegar volcanoes are like a rite of childhood passage, but there are so many other amazing science ideas out there! I have compiled a list of 30+ science fair projects for kids based on their grade level below. Before we get started I wanted to share some tips for getting the most out of the science fair. This post contains affiliate links. Science Fair Tips Don’t do the project for your child! This is my number one tip. Many parents have a tendency to jump in and make children’s work “more presentable” or to assist their child so much in the project that it’s hard to know who actually did it. Listen I get it, science is fun and you want your child to have a wonderful presentation…but that’s not really what the science fair is about. It’s about your child learning how to do scientific research and present their findings in their own way. Think of yourself as a helpful guide NOT an assistant, and definitely not the boss. Choose something age  appropriate  When your child is choosing the science fair idea they want to try, make sure it’s age appropriate. Sure we’d all love to make a working robot but there’s nothing more frustrating than trying a project that may be too advanced for the skills of your child. And that’s when a lot of parents resort to doing the project instead. Not a good solution. So make sure your child is capable of completing the steps them self. Make a list of three ideas Have your child select three science fair project ideas and then go over the choices with them. Make sure they understand the steps involved in each project and wether or not they feel comfortable in executing those steps on their own with your guidance. Follow your child’s interests Encourage your children to explore some ideas based on interests they already have. Here’s a list of science books with projects based on things your child already loves! STEAM it up! STEAM projects rock the science fair!!! A great way to get kids to become more familiar with STEAM concepts it to pick science projects that crossover into art, math, engineering and more!  Two STEAM books to consider are  STEAM Kids Play and Learn (my book!) and   STEAM Kids ebook.  Both books will get you started with some great ideas! Read our Science Fair Mini Guide I created this mini guide to walk kids  through all the steps for completing their science fair project. You can check out the full guide here:  Speak like a scientist! Science Vocabulary to use in your presentation We’re almost ready to get to the projects! Before we begin, let’s review some science terms. In fact, using these terms in your science fair presentation will be sure to impress your friends and adults! When you watch, see, or notice something you are making an observation When you ask who, what, when, where, why, or how, you are forming a question   When you read a book or an article about your observation, you are doing research When you make a guess based on your observation, question, and research, you are forming a hypothesis When you test your hypothesis, you are conducting an experiment When you change one factor in your experiment at a time while keeping everything else the same, you are changing a variable When you take notes in your journal and write down what you see happening in your experiment, you are logging data   When you examine, or look at, your data, you are analyzing it When you are able answer your question, you are coming to a conclusion 30+ Science Fair Projects for Kids  Now let’s get on with the science fair projects! I have organized the projects by age/grade level. Click the titles to be taken to the project instructions, unless the instructions follow below.

Pin It on Pinterest Science Bob Experiments Science Fair Ideas Science Q&A Research Help Experiment Blog Okay, this is the hardest part of the whole project…picking your topic. But here are some ideas to get you started. Even if you don’t like any, they may inspire you to come up with one of your own. Remember, check all project ideas with your teacher and parents, and don’t do any project that would hurt or scare people or animals. Good luck! Does music affect on animal behavior? Does the color of food or drinks affect whether or not we like them? Where are the most germs in your school? ( CLICK for more info. ) Does music have an affect on plant growth? Which kind of food do dogs (or any animal) prefer best? Which paper towel brand is the strongest? What is the best way to keep an ice cube from melting? What level of salt works best to hatch brine shrimp? Can the food we eat affect our heart rate? How effective are child-proof containers and locks. Can background noise levels affect how well we concentrate? Does acid rain affect the growth of aquatic plants? What is the best way to keep cut flowers fresh the longest? Does the color of light used on plants affect how well they grow? What plant fertilizer works best? Does the color of a room affect human behavior? Do athletic students have better lung capacity? What brand of battery lasts the longest? Does the type of potting soil used in planting affect how fast the plant grows? What type of food allow mold to grow the fastest? Does having worms in soil help plants grow faster? Can plants grow in pots if they are sideways or upside down? Does the color of hair affect how much static electricity it can carry? (test with balloons) How much weight can the surface tension of water hold? Can some people really read someone else’s thoughts? Which soda decays fallen out teeth the most? What light brightness makes plants grow the best? Does the color of birdseed affect how much birds will eat it? Do natural or chemical fertilizers work best? Can mice learn? (you can pick any animal) Can people tell artificial smells from real ones? What brands of bubble gum produce the biggest bubbles? Does age affect human reaction times? What is the effect of salt on the boiling temperature of water? Does shoe design really affect an athlete’s jumping height? What type of grass seed grows the fastest? Can animals see in the dark better than humans? Didn’t see one you like? Don’t worry…look over them again and see if they give you an idea for your own project that will work for you.

Science Activities For Toddlers Preschool Science Experiments Kindergarten Science Experiments First Grade Science Projects Elementary Science Projects Science Projects For 3rd Graders Science Experiments For Middle Schoolers How To Teach Science Kids are curious and always looking to explore, discover, check out, and experiment to discover why things do what they do, move as they move, or change as they change! My son is now 13, and we started with simple science activities around three years of age with simple baking soda science. Here are great tips for making science experiments enjoyable at home or in the classroom. Safety first: Always prioritize safety. Use kid-friendly materials, supervise the experiments, and handle potentially hazardous substances yourself. Start with simple experiments: Begin with basic experiments (find tons below) that require minimal setup and materials, gradually increasing complexity as kids gain confidence. Use everyday items: Utilize common household items like vinegar and baking soda , food coloring, or balloons to make the experiments accessible and cost-effective. Hands-on approach: Encourage kids to actively participate in the experiments rather than just observing. Let them touch, mix, and check out reactions up close. Make predictions: Ask kids to predict the outcome before starting an experiment. This stimulates critical thinking and introduces the concept of hypothesis and the scientific method. Record observations: Have a science journal or notebook where kids can record their observations, draw pictures, and write down their thoughts. Learn more about observing in science. We also have many printable science worksheets . Theme-based experiments: Organize experiments around a theme, such as water , air , magnets , or plants . Even holidays and seasons make fun themes! Kitchen science : Perform experiments in the kitchen, such as making ice cream using salt and ice or learning about density by layering different liquids. Create a science lab: Set up a dedicated space for science experiments, and let kids decorate it with science-themed posters and drawings. Outdoor experiments: Take some experiments outside to explore nature, study bugs, or learn about plants and soil. DIY science kits: Prepare science experiment kits with labeled containers and ingredients, making it easy for kids to conduct experiments independently. Check out our DIY science list and STEM kits. Make it a group effort: Group experiments can be more fun, allowing kids to learn together and share their excitement. Most of our science activities are classroom friendly! Science shows or documentaries: Watch age-appropriate science shows or documentaries to introduce kids to scientific concepts entertainingly. Hello Bill Nye and the Magic Schoolbus! You can also check out National Geographic, the Discovery Channel, and NASA! Ask open-ended questions: Encourage critical thinking by asking open-ended questions that prompt kids to think deeper about what they are experiencing. Celebrate successes: Praise kids for their efforts and discoveries, no matter how small, to foster a positive attitude towards science and learning. What is the Scientific Method for Kids? The scientific method is a way scientists figure out how things work. First, they ask a question about something they want to know. Then, they research to learn what’s already known about it. After that, they make a prediction called a hypothesis. Next comes the fun part – they test their hypothesis by doing experiments. They carefully observe what happens during the experiments and write down all the details. Learn more about variables in experiments here. Once they finish their experiments, they look at the results and decide if their hypothesis is right or wrong. If it’s wrong, they devise a new hypothesis and try again. If it’s right, they share their findings with others. That’s how scientists learn new things and make our world better! Go ahead and introduce the scientific method and get kids started recording their observations and making conclusions. Read more about the scientific method for kids .
