Top 5 physics experiments you can do at home

October 17, 2022 By Emma Vanstone Leave a Comment

Physics is key to understanding the world around us. While some aspects may seem tricky to understand, many fundamental physics concepts can be broken down into simple concepts, some of which can be demonstrated using basic equipment at home.

This list of 5 physics experiments you can try at home is a great starting point for understanding physics and, hopefully a source of inspiration for little scientists everywhere!

Physics experiments you can do at home

1. archimedes and density.

The story behind Archimedes’ discovery of density is that he was asked by the King of Sicily to work out whether a goldsmith had replaced some gold from a crown with silver. Archimedes needed to determine if the goldsmith had cheated without damaging the crown.

The crown weighed the same as the gold the King had given the goldsmith, but gold is more dense than silver, so if there were silver in the crown its density would be less than if it were pure gold. Archimedes realised that if he could measure the crown’s volume, he could work out its density, but calculating the volume of a crown shape was a tough challenge. According to the story, Archimedes was having a bath one day when he realised the water level rose as he lowered himself into the bathtub. He realised that the volume of water displaced was equal to the volume of his body in the water.

Archimedes placed the crown in water to work out its density and realised the goldsmith had cheated the king!

Density Experiment

One fun way to demonstrate density is to make a density column. Choose a selection of liquids and place them in density order, from the most dense to the least dense. Carefully pour a small amount of each into a tall jar or glass, starting with the most dense. You should end up with a colourful stack of liquids!

2. Split light into the colours of the rainbow

Isaac Newton experimented with prisms and realised that light is made up of different colours ( the colours of the rainbow ). Newton made this discovery in the 1660s. It wasn’t until the 1900s that physicists discovered the electromagnetic spectrum , which includes light waves we can’t see, such as microwaves, x-ray waves, infrared and gamma rays.

How to split light

Splitting white light into the colours of the rainbow sounds tricky, but all you need is a prism. A prism is a transparent block shaped so light bends ( refracts ) as it passes through. Some colours bend more than others, so the whole spectrum of colours can be seen.

If you don’t have a prism, you can also use a garden hose! Stand with your back to the sun, and you’ll see a rainbow in the water! This is because drops of water act like a prism.

3. Speed of Falling Objects

Galileo’s falling objects.

Aristotle thought that heavy objects fell faster than lighter objects, a theory later disproved by Galileo .

It is said that Galileo dropped two cannonballs with different weights from the leaning tower of Pisa, which hit the ground at the same time. All objects accelerate at the same rate as they fall.

If you drop a feather and a hammer from the same height, the hammer will hit the ground first, but this is because of air resistance!

If a hammer and feather are dropped somewhere with no air resistance, they hit the ground simultaneously. Commander David Scott proved this was true on the Apollo 15 moonwalk!

Hammer and Feather Experiment on the Moon

Brian Cox also proved Galileo’s theory to be correct by doing the same experiment in a vacuum!

While you won’t be able to replicate a hammer or heavy ball and feather falling, you can investigate with two objects of the same size but different weights. This means the air resistance is the same for both objects, so the only difference is the weight.

Take two empty water bottles of the same size. Fill one to the top with water and leave the other empty. Drop them from the same height. Both will hit the ground at the same time!

4. Newton’s Laws of Motion

Sir Isaac Newton pops up a lot in any physics book as he came up with many of the laws that describe our universe and is undoubtedly one of the most famous scientists of all time. Newton’s Laws of Motion describe how things move and the relationship between a moving object and the forces acting on it.

Making and launching a mini rocket is a great way to learn about Newton’s Laws of Motion .

The rocket remains motionless unless a force acts on it ( Newton’s First Law ).

The acceleration of the rocket is affected by its mass. If you increase the mass of the rocket, its acceleration will be less than if it had less mass ( Newton’s Second Law ).

The equal and opposite reaction from the gas forcing the cork downwards propels the rocket upwards ( Newton’s Third Law ).

4. Pressure

Pressure is the force per unit area.

Imagine standing on a Lego brick. If you stand on a large brick, it will probably hurt. If you stand on a smaller brick with the same force it will hurt more as the pressure is greater!

Snowshoes are usually very wide. This is to reduce the pressure on the snow so it sinks less as people walk on it.

Pressure and Eggs

If you stand on one egg, it will most likely break. If you stand on lots of eggs with the same force, you increase the area the force is applied over and, therefore, reduce the pressure on each individual egg.

That’s five easy physics experiments you can do at home! Can you think of any more?

80 of the Best Physics Projects for Clever Kids

February 21, 2020 by Ana Dziengel Leave a Comment

Physics projects are some of the most memorable science projects your kids will ever try. There, I said it even if you don’t believe it!

You see, physics is the branch of science that studies flying, launching, moving, and floating, as well as magnets, motors and electrical circuits, heat, light, and sound. Physics is fun! After you look over some of the projects in this collection I hope you’ll agree.

Now before we begin I want to address a common notion a lot of folks have about this branch of science: Physics is really hard! I completely understand this thought.

In fact the only class I ever almost failed in my entire academic career was physics. And I know why. Physics was presented to me as formulas about force, equilibrium, and momentum with not one single demonstration. Then I walked into a structural engineering class where we discussed the forces at work in designing buildings and my teacher told us he didn’t want us to open a book all quarter. Instead he told us to build models. He wanted us to experiment with how forces really interact in a structure by testing them in hands-on experiments. It was a profound experience for me and suddenly all the book learning “clicked.”

My goal with this collection of projects is to make physics more accessible and inviting to parents, teachers, and kids alike! But before we dive into the physics projects let’s get a bird’s eye view of what physics is all about!

What is the study of physics?

Physics is the branch of science that studies matter, how it moves and how it interacts. It is a HUGE topic and there is a lot of overlap with chemistry and biology. It’s really easy to hear the word physics and have your eyes glaze over, but in simple words physics is the study of how things move and interact with each other.

How do you explain physics to a child?

The best way to explain physics to kids is to skip an explanation and do a demonstration . Since physics encompasses the study of motion, light, electricity, magnetism, and aerodynamics, instead of trying to explain these concepts demonstrate them! I am a big believer in hands-on projects that give kids a chance to experience and experiment with a scientific concept rather than just hear or read about it. We all know an amazing project is memorable while a wordy explanation is forgettable. Kids are great visual learners so give them the chance to get excited about physics through projects!

What are main branches of Physics?

While I was assembling this post I realized scientists define the branches of physics in many different ways. The following is a list of the most commonly cited branches of physics compiled from both online and offline resources:

• Mechanics This includes force, motion, fluid and aerodynamics, and is the branch most people think of when they hear the word physics.
• Electromagnetism Electricity is physics!

Thermodynamics

• Sound and Waves
• Quantum Mechanics This is for the very serious! It’s the branch that studies atomic particles.

80+ Physics Projects for Kids

How to use this guide.

The physics projects for kids featured here are sorted by branches of physics and subcategories as follows (click on the topic to skip to that section) :

• Mechanics and Motion: Work & Energy, Newton’s Law’s of Motion, Radial Forces, Gravity, and Balance
• Electromagnetism & Electricity: Magnetism, Electricity

Optics & Sound

• Heat, Liquids, and Air: Thermodynamics, Hydrodynamics, & Aerodynamics

Some topics and categories were really easy to find great projects for (work and energy) some were more challenging (thermodynamics) and at least one impossible (Quantum mechanics, but that’s okay!). We tried to assemble as many as we could on this list!

Please note that many of these projects could fit in two or more categories as they demonstrate various principles and forces. I only classified them once on this list.

Mechanics and Motion

When most people think of physics they think about mechanics and motion. Mechanics refers to the motion of objects and motion is the position change of an object over time. Everything around us is constantly in motion. Even when we consider ourselves to be sitting still, the earth is rotating on its axis and moving around the sun.

Scientists have studied motion over the centuries and determined there are laws that can explain the motion of objects. These laws revolve around the idea of forces .

A force is something that pushes or pulls on an object to make it move. A force can make an object speed up (like kicking a ball) or or slow down (like friction) or hold an object in place (like gravity). Momentum is the force an object has based on its weight and motion. For a deeper look into forces go here .

In this section we’ll cover projects that focus on motion including 3 of the most famous laws of motion as outlined by Sir Isaac Newton.

Work and Energy Projects

Energy is defined as the ability to do work. Work refers to the amount of energy needed to move something over a distance using a force. The Law of Conservation of Energy states that energy is never created or destroyed it is simply changed from one state to another.

Potential Energy vs. Kinetic Energy

Two types of energy frequently disucssed in phyiscs are kinetic energy and potential energy. Kinetic energy is energy in motion. Potential energy is energy that is stored. An example of potential enrgy is a rubber band twisted up and held in place. Once the rubber band is released it unwinds quickly as kinetic energy.

Here are some projects that demonstrate work and energy:

Physics Project Idea: Rollback Can

Steam activity: stixplosions, how to build a catapult, transfer of energy science experiment, catapult stem project – diy catapult for kids, how to make a windmill model with a printable pattern, simple machines for kids: lego pulleys stem building challenge, power up your planes with a paper airplane launcher, featured work & energy videos:, newton's laws of motion.

Sir Isaac Newton was a mathematician and scientist who studied motion in the 1600's. He is credited with discovering the force of gravity as well as developing three laws of motion to describe how objects move. We'll look at each law of motion and some projects that highlight them below.

Newton's First Law of Motion is called the Law of Interia and states: An object at rest tends to stay as rest and an object in motion tends to stay in motion unless acted upon by an external force.

Newton's Second Law of Motio n states that the acceleration of an object depends on the force applied to the object and the object's mass. The relationship can be described with the following formula: F=ma

Force= Mass x Acceleration

Newton's Third Law of Motion states: For every action there is an equal and opposite reaction.

Here are some projects that focus on the laws of motion:

How To Make A Simple Newton's Cradle

Easy inertia science experiments with pennies, inertia zoom ball: super fun s.t.e.a.m. project, make a balloon pinwheel science demonstration, physics activities that explore newton's laws of motion, radial forces.

Kids love things that spin! There are several types of forces and movement that act upon objects as they spin:

Angular Momentum The momentum of an object rotating around a point.

Centripetal Force A force that pulls an object towards the center point, causing it to move in a circular path. The force is always orthogonal to the fixed center.

Centrifugal Force A force that pushes away from the center as an object is spinning. It's not a REAL force but an apparent force.

Friction is a force that slows down objects sliding against each other. It's the reason that spinning tops eventually slow down. If there was no friction on between the point on which a top spins and the surface on which it is spinning, it would spin forever!

Action Art: Spin Art Using a Bike

Diy spin art: art spinners from steam play & learn, simple paper toys: paper tops, homemade toy idea: diy skip-it, diy toys: spinning tops (+ magical disappearing colors), diy toy idea: spin-finite tops, gorgeous spin art hearts painting activity for kids, easy fidget spinner diy (free template) - science fair project idea, halloween science for kids: pumpkin spinning tops, stem toy: penny spinners, featured radial forces videos:.

Gravity is a force that attracts two bodies together. It's also the natural force that pulls everything towards the earth. The greater the mass of an object the more garvitational pull it has.

Scientists measure the acceration of gravity at the Earth's surface at 32 feet per second squared! That means the longer an object is free falling the more it's speed increases (not accounting for air resistance).

Here are some phyics projects for kids that explore the force of gravity and speed:

Recycled DIY Marble Run

Playground sized diy marble run, science & art for kids: salt pendulum.

Substitute paint for the sand to make a painting pendulum!

Drippy Gravity Painting | TinkerLab

Gravity beads experiment, the lincoln high dive, egg drop project with printable recording sheets, preschool science: weight, featured gravity videos:.

In phyiscs we use the word balance to describe a situation in which two forces are equal in magnitude and extered in opposite directions.

See saws and scales are two easy wasy to illustrate the concept of balance to kids. Here are some additonal project ideas:

How to Make a Balance Toy: Balance Hearts STEAM Activity

Diy balance toy & game, awesome earth day activity: make an earth balancer, how to make balance scales for toddlers and preschoolers, easy kid's craft: straw mobile, engineering for kids: twirling twig mobile, featured balance project videos, electromagnetism & electricity.

Did you know that electricity and magnetism are physics topics? Both of these “invisible” forces are some of kids’ favorites to explore through hands-on projects!

Magnetism describes a force that attracts or repels objects that are made of magnetic material.

A magnet is a type of material that attracts iron and produces it's own magnetic field. Magnets have a north and a south pole. If you hold two magnets close to each other and place like poles together the magnets will repel each other. If you place the opposite poles together they will quickly attract each other.

Science and Art for Kids: Magnetic Sculptures

The creepiest slime ever: how to make magnetic slime, 4 easy magnet experiments that will amaze your kids, science for kids: bouncing magnets, steam camp: how to make a magnetic field sensory bottle, how to make a compass - magnetic science experiment for kids, five minute craft: magnet painting, make an aladdin magic flying carpet, traveling magnets, easy science experiments for kids: gravity activity with paperclips, featured magnetism videos, electricity.

Electrical force is a force that causes electically charged bodies to either repel or attract. It's the force that carries electrical current through a wire. There are two types of electrical charges: positive and negative.

Similar to magentism like charges REPEL each other and opposite charges ATTRACT each other.

Here are some fun ways to explore elctriclty with kids.

What we see and hear is determined by physics! This includes the behavior of light waves and sounds waves, those that we can perceive and those we cannot.

Light is a type of energy made up of photons. Our eyes can perceive some of it and some forms we cannot perceive at all. Light travels in both wave form and particle form.

Photons are particles which can transmit light.

Optics is the study of light's behavior as well as tools we use to study and understand it, including how our eyes perceive it.

Sound is a vibration that travels in waves and can be detected by the ear. Sound can be transmitted through air, water, and solids.

Here are some projects that make use of sound and vibrations:

Physics also covers the study of heat and fluid dynamics which includes aerodynamics (the study of movement in air and gases) and hydrodynamics (the study of movement in liquids) .

Thermodynamics is the branch of physics that studies heat and heat transfer. When two obejcts of different temperatures come in contact, energy will transfer between them until they reach the same temperature and are in a state of equilibrium. Heat always transfers from the higher temperature to a lower temperature. You can read more about heat here.

Heat Sensitive Color Changing Slime

Kids science: flying tea bag hot air balloon, magic jumping coin trick, convection detection, inverted bottles, convection currents, featured thermodynamics videos, hydrodynamics.

Hydrodynamics is the study of how fluids move and behave and the forces they exert. And let's be honest, kids love playing with water so use it an an entree to science!

Magic Potions Density Tower

After playing with water I'd say thay making things fly ranks very high on kids' must try list! Aerodynamics focuses on air movement and the forces at work as objects move through the air. It's the physics branch that let's kids explore building planes, helicopters, and rockets!

How To Make A Paper Helicopter

Diy toy: zappy zoomers, awesome science experiments with hot wheels cars, whirly twirly flying birds, stem for kids: straw rockets (with free rocket template), make an indoor paper boomerang with the kids, straws circle paper planes - s.t.e.m. for kids, how to make awesome paper airplanes 4 designs, more physics for kids resources.

Physics Experiments For Kids [7 Awesome Ideas]

Physics experiments for kids are a perfect introduction to the fantastic world of science. Physics experiments challenge you to think about the hidden forces that drive the world. Even easy science experiments for kids can teach surprising lessons and reveal how fascinating the world is.

Here are a few fun physics projects you can try at home.

Physics Experiments for Kids

Powerful paper construction.

This is one of my favorite STEM activities. All you need is

• Scotch tape
• A stack of books/ one book and heavy items to balance on top of it

All great science experiments start with a question, ‘Can you use paper and tape to build a structure strong enough to support a book?’

I suggest posing the question and then seeing what your kids come up with. Trying and failing is part of a physics experiment.

When they’re ready, you can show them a solution. You roll the paper into a tube and use a small piece of tape to hold it in that shape. With four tubes, you can easily support an impressive number of books.

To extend the project, your kids can investigate which size and shape of the tube are the strongest. If your child is competitive, then why not make it a fun competition.

So Why Isn’t The Paper Crushed By The Books?

It’s all about the shape. A cylinder is one of the most robust shapes. Because it has a circular shape running all along the length, this evenly distributes the books’ weight. So no one point on the paper takes more stress and weakens.

Another illustration of this is with a soda can. You can try crushing a soda can — it’s really hard. An average can will support the weight of an average adult. But if you squash it a little in the middle, then try again, it suddenly crumples up. With its shape damaged, the weight is no longer evenly spread.

Lego Balloon Car/ Zipline

I’ve bundled these two physics experiments for kids together because they both use LEGO to explore some exciting physics ideas.

In both of these awesome physics experiments, your child has the chance to build their own creation and see how it performs. They can then tweak their design and process to improve the performance of what they’ve made. They can either make a balloon-powered car or build a ‘carrier’ to help a LEGO man ride a zipline.

There are so many ways that you can explore science, starting from these simple physics experiments. You can try to make the car travel further by changing either the vehicle or the balloon. You can find the perfect slope to get the LEGO man down the zipline as fast as possible, without his vehicle breaking at the end. You can measure the distances and times for older kids and calculate how fast their creations are going.

If you want to use these experiments to introduce some physics ideas, both of them touch on ideas of

• Potential and kinetic energy
• Friction and air resistance
• Speed, velocity, and acceleration
• Newton’s laws of motion

Fireproof Balloon

Have you ever been to a birthday party with a few too many balloons? If so, you might have noticed that if they get too near something warm, they pop. A great demonstration of this is with a balloon and a small candle. Blow up the balloon, hold it over the candle, and… pop!

In this simple physics experiment, you are going to make that balloon fireproof! Before you blow it up, you put some water in the balloon. Now when you bring the candle close… nothing happens. Just like magic, only better — science!

So What’s Going On?

First, let’s talk about why the balloon pops when it gets hot. The heat is transferred to the air molecules inside the balloon. They use that heat energy as kinetic energy, which means they start to move around faster. As the molecules spread out, they push harder on the balloon, until they push hard enough to break it.

So why does adding water help? It’s because water is amazing. Honestly, the science of water is fascinating. If it didn’t react to heat the way it does, we wouldn’t be here at all. Water is really good at absorbing heat. It takes a lot of heat energy to warm water up by even a small amount.

The heat from the candle gets absorbed by the water instead of the air molecules. The water needs over 4,000 times more energy to increase its temperature by a single degree than the air does. The same energy doesn’t do much to the water, and the temperature inside the balloon barely changes.

Using Gravity To Find A Cooked Egg

This incredibly simple physics experiment is just the sort that I love. It looks like magic from a distance, and if you’re the dramatic sort, you can play it that way to get your kids interested.

All you need to do is boil an egg in advance and then pop it in the fridge to cool. If you want to pretend you have magic powers, you should boil two to reveal the trick afterward. Present your kids with a row of identical eggs and ask if they can find the cooked one, without breaking any eggs.

The trick is to spin them. Cooked eggs spin much better than raw ones.

This teaches a critical lesson about physics. It shows how you can use science to uncover information that you can find out just from looking. Physics lets you ‘peek’ inside to find out what’s going on.

Extending The Idea

Here’s another experiment that explores the same idea. You need a long stick, around 1m is perfect, and a piece of clay. Put a fist-sized piece of clay around the stick. The clay should be towards one end of the stick, about 20 cm away from the end is perfect. Then try and balance the stick vertically on the palm of your hand.

The position of the clay makes a huge difference. When the clay is near the top, the stick rotates more slowly, making it easier for you to keep it balanced. It’s all about the position of the center of gravity.

Floating/Sinking Oranges

When it comes to simple physics experiments, it doesn’t get much simpler than this. All you need is:

• A bowl of water.

This is perfect if your kids have recently been doing science experiments about sinking and floating.

Ask your kids if they think an orange will sink or float. Then try it to see. So, it floats, not that exciting. But, what if you peel the orange, will that make a difference? Make sure to ask your kids to explain their reasoning.

If they have been learning about sinking and floating, they will likely say that it will still float, or it will float higher because you’re making it lighter. Which is why they’ll, hopefully, be amazed to find that without its peel, your orange sinks.

The question is, why?

Why do ‘Lighter’ Oranges Sink?

This is all about density. The peel of an orange is full of air pockets; they help protect it when it falls to the ground. They also reduce the density. When you take the peel off, it’s like taking off the orange’s life vest.

When it comes to a list of physics experiments for kids, it’s hard not to include catapults . After all, what child doesn’t like the idea of launching things into the air?

You can build catapults out of loads of household objects. The easiest to get hold of is popsicle sticks for the frame, a rubber band for the elastic energy store, a bottle cap to hold the projectile, and some glue to hold it all together. I recommend cotton balls or ping pong balls for a projectile — something that won’t hurt too much if someone’s aim is wandering.

There are so many physics ideas to explore inside these constructions, and so many variations to try. If your kids really enjoy this, you can try other similar science experiments to extend the ideas. For instance, you can learn about Trebuchets and try to build one of those instead.

Blowing Water Up A Straw

Here what you need to try this science experiment:

• Shallow bowl/saucer of water

The challenge – Can you lift the water out of the saucer, using the straw without sucking?

So how do you do it? You need to cut a small 3cm section off the end of your straw. You’ll then use your tape to stick the little piece back on. Except when you stick it back on, it should now be at 90 degrees to the rest of the straw. It should have one edge touching the rest of the straw. If it looks like a capital L, you’ve got it right.

Then you put the short end of the straw in the water and blow through the long end. If it doesn’t work, blow a bit harder!

What’s Going On?

When you blow, it creates an area of low pressure at the top of the small straw. Because the air pressure over the saucer is now higher, it pushes the water up the straw.

Frequently Asked Questions

How do you teach kids physics.

Physics is a way of looking at the world. It’s learning to ask questions about how and why things happen the way they do. So, a great way to teach kids about physics is to encourage them to ask questions.

When you see something interesting, ask them why they think it happened. Physics, like all of science, is about curiosity and creativity. The best way to help your child learn about physics is to ask questions, try and think of answers together, and then test your ideas.

Isn’t physics really hard?

A lot of adults think that science and physics especially are hard. A lot of that is to do with how it was taught. If you learned physics by memorizing equations and rote learning, it would always seem complicated and boring.

But, the basic ideas of physics aren’t that hard to understand, even for kids. Simple physics experiments are a great tool to help kids love physics. When you love learning about a topic, it doesn’t seem so hard.

Why should kids learn physics?

Physics is amazing to learn about because it is behind everything in the world. Without an understanding of physics, we’d be stuck in the dark ages.

It’s really easy to take all our modern technology for granted. When you learn about physics, you discover how amazing it really is. For instance, did you know that your phone relies on quantum physics to work?

Trying out physics projects at home is a fantastic way to get kids interested in learning more about the world around them.

Sandy is an experienced STEM educator, having spent a decade teaching Physics. She also loves to volunteer at local STEM fairs to show kids, especially girls, how awesome it is. She is so passionate about science that one science degree wasn’t enough and she decided to complete a second part-time, while working.

10 ideas for physics demonstrations to use in your classroom.

If done appropriately, in-class physics demonstrations can be a great way to engage students and exhibit key concepts. Dr. Adam Beehler , Lecture Demonstration Specialist at the University of Utah shares a few of his favorites in the list below. Many of these examples are simple to implement in any classroom, though if resources are a concern, utilizing a video of the demonstration may be an effective alternative.

• Rotational Inertia Race (North Carolina School of Science and Mathematics)

In this example, two concurrent demonstrations are utilized to illustrate that rotational inertia depends on the mass of an object and the ways in which it is distributed from the axis of rotation. An important aspect of this demonstration is making clear that angular acceleration is directly related to the ratio of torque to rotational inertia. While the first experiment does require the use of a motor to get an aluminum disk in motion, the second only requires setting up a ramp for two disks (one wood, one aluminum) to roll down.

• Bicycle Wheel Gyroscope (Veritasium)

By manually spinning a bicycle wheel that is hanging from a rope from one of its axles, this short demonstration, which could easily be shown as an in-class video, illustrates the interaction of the torque of the spinning wheel with that of gravity.

• Ice Skater Spin (Steve Spangler Science)

This experiment adapts the idea of a spinning ice skater to illustrate angular momentum by having a participant in the experiment stand on a flat rotating disk. Whether using the disk or a spinning chair, having students participate in this demonstrate may also be useful, keeping safety in mind. When students hold weights or books at the end of their arms they increase their rotational inertia, meaning they have a larger change in angular velocity when their arms are brought in as compared to when their hands are pulled in without any weights.

• Falling Monkey (Harvard Natural Sciences Lecture Demonstrations)

Some demonstrations are better shown as videos, such as the Monkey and a Gun experiment. This version of the demonstration suspends a stuffed monkey from a rod with an electromagnet on one side of a lecture hall with a golf ball gun aimed at the monkey from the other side. When the gun is fired, it cuts power to the electromagnet, causing the monkey to fall. The earth’s gravitational field accelerates all objects at the same rate, be they monkeys or golf balls.

• Magdeburg Hemispheres (Physics Demonstrations by Julien C. Sprott, Ch. 2)

Using a vacuum, the air from two hemispheres placed together is pumped out and participants attempt to pull them apart. While we don’t endorse any particular vendor, you can find an inexpensive version of this demonstration at Harbor Freight , which  doesn’t require the use of a vacuum pump. If you choose this route, it works a little differently in that the quick release handles change the curvature of the suction cups, thereby increasing the volume (and decreasing the pressure) inside creating a partial vacuum.

• Bending a Laser (Fizik.si)

In order to demonstrate total internal reflection, a small laser is pointed through a hole in a 1L plastic bottle filled with water. The total reflection is evident if the light enters an optically less dense material and the incidence angle is big enough. The incidence angle at which the ray refracts exactly along the boundary line is called the boundary angle of the total reflection.

• Jumping Ring (MIT Physics Lecture)

Two metal rings, one solid and one with a small hole cut in it, are placed on an iron core wrapped in wire. AC and DC power are run through the wire with each ring. The experiment is rerun after submerging the solid metal ring in liquid nitrogen, which lowers the resistance of the ring, causing a greater effect.

• Pith Balls (Saint Mary’s University, Physics)

Two pith balls are suspended from a string. After being rubbed with silk, a glass rod is used to touch the pith balls, which repel each other. An ebonite rod rubbed with fur attracts the pith balls, which demonstrates electrostatic attraction and repulsion.

• Egg in a Bottle (Fizik.si)

A small piece of paper is partially burned in a narrow-mouthed glass flask and a peeled, hard-boiled egg is placed in the mouth of the flask. The differential atmospheric pressure inside and outside of the flask cause the egg to be drawn into the flask.

• Metal Ball and Ring (NormandinEdu)

A metal ball attached to a metal rod, which fits through a metal ring, is heated, which causes the metal to expand and no longer fit through the ring due to thermal expansion.

In previous blogs, we discussed the  pros and cons of in-class physics demonstrations , as well as some  guidelines for using them in class successfully. Some key takeaways from these discussions include that in-class demonstrations are most effective when experiments exhibit simplicity, are counterintuitive, and are integrated into an active-learning context.

Keeping students engaged is vital across all aspects of a course, from in-class activities to homework. Expert TA has determined optimal grade settings for student success in online homework. Read more about these results from a massive case study involving more than 120 classes.
