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?

Cool Physics Experiments to Do at Home

Cool Physics experiments will not only fascinate and amaze your kids but will teach them about important scientific principles.

Some coolest physics experiments include Newton’s cradle, the simple Bernoulli experiment, the balloon rocket experiment, and the density tower experiment. Learn about atmospheric pressure with the egg in the bottle and the rising water experiments.

In this blog post, I will share the details of these and more cool physics experiments that are perfect for young kids and teenagers. These experiments are not only educational but also fun. I hope you enjoy them.

7 Cool Physics Experiments to Do at Home

Here are the 7 most fun Physics experiments you can do at home.

1. Newton’s Cradle Experiment

Newton’s cradle experiment demonstrates the conservation of momentum and energy.

How to do it

You will need the following items:

• A set of Newton’s Cradle balls (or any type of metal balls that are identical in size and weight)
• A table or other flat surface
• Strings that are the same length

Attach one end of each string to a different ball. Suspend the balls from a frame so that they are touching each other. You can easily achieve this by making sure the strings are the same length and attaching them to a board at the same height.

Pull back one ball and release it so that it hits the middle ball. The released ball will swing up and hit the ball at the opposite end. That ball will then swing up and hit the ball next to it and so on. The last ball will swing up and hit the first ball, starting the process all over again.

The results explained

What is happening is that the balls are colliding in such a way that the momentum of each ball is conserved. In other words, the combined momentum of all the balls before the collision is equal to the combined momentum of all the balls after the collision.

The energy is also conserved in this experiment. The energy is converted from kinetic energy (the energy of motion) to potential energy (the energy stored in the balls as they are raised up) and back to kinetic energy again.

This is a simple but elegant demonstration of some very important scientific principles. Try it yourself and see.

2. The Simple Bernoulli Experiment

The Bernoulli principle is one of the most important principles of fluid dynamics. It explains how wings generate lift and how airfoils work. When the speed of a fluid increases, the pressure decreases. This principle is what makes flight possible.

Here’s how to do it

• A piece of paper
• A pair of scissors

Cut a rectangular piece of paper that is about twice as wide as the straw. Fold the paper in half lengthwise and tape it together.

Cut a slit in the center of the paper, being careful not to cut all the way through. Insert the straw into the slit and tape it in place. Now blow gently across the top of the paper. What happens?

When you blow across the top of the paper, the airspeed above the paper increases. An increase in airspeed means a decrease in pressure. The decrease in pressure on the top of the paper is greater than the increase in pressure on the bottom of the paper. This creates a force that lifts the paper up into the air.

This is how airplanes generate lift. The wings are shaped so that the air travels faster over the top of the wing than the bottom. This decreases the pressure on the top of the wing and creates lift.

Try this experiment with different shapes of paper and see how it affects the results.

3. The Egg in the Bottle Experiment

This experiment demonstrates how atmospheric pressure and temperature can affect the shape of an object.

• A hard-boiled egg
• A glass bottle with a narrow neck

Remove the shell from the hard-boiled egg. Place it in the mouth of the glass bottle. The mouth should be just smaller than the egg in diameter so the egg doesn’t fall through.

Roll the piece of paper into a cone shape and hold it over the neck of the bottle. Light the paper on fire, remove the egg and drop the burning paper into the bottle. Quickly place the egg back in the mouth of the bottle. What happens?

The fire goes out almost immediately because the oxygen in the bottle is quickly used up. After some time, the egg drops into the bottle.

Before we placed the burning paper into the bottle, the atmospheric pressure inside the bottle was the same as the atmospheric pressure outside. So there was no pressure pushing the egg into the bottle.

When we placed the burning paper in the bottle, it heated up the air inside the bottle. The air inside the bottle expanded. When we sealed the bottle with the egg, the fire went out and the air inside the bottle contracted. This created a vacuum.

The atmospheric pressure outside the bottle became greater than the atmospheric pressure inside the bottle, so the egg was forced into the bottle.

4. The Balloon Rocket Experiment

The Balloon Rocket is a classic physics experiment that demonstrates Newton’s Third Law of Motion: for every action, there is an equal and opposite reaction. In simple terms, it is all about thrust.

• Two chairs or a table
• A plastic clip or peg

Place two chairs a few feet apart or use a table. Cut a length of string and tie one end to the back of one chair. Thread the other end through the straw and tie it to the back of the other chair. The string should be taut but not too tight.

Cut two small pieces of tape and affix them on the top part of the straw, about an inch apart. These will be used to hold the balloon in place.

Blow up the balloon, twist the neck, and use the peg to make sure the air doesn’t escape. Now attach the balloon to the straw using the two pieces of tape.

Remove the peg and release the balloon and watch it fly!

Once you remove the peg and release the balloon, the air will rush out of the balloon in one direction with great force. The straw will be forced in the opposite direction with an equal force. This is because of Newton’s Third Law of Motion. The faster the air rushes out of the balloon, the greater the force will be.

5. The Candle in the Jar Experiment

This experiment is a great way to learn about the relationship between air and combustion.

• A glass jar
• A wooden board or a ceramic plate
• A lighter or matches

Light the candle and place it on a wooden board or ceramic plate. Quickly put the glass jar upside down on top of the candle. After some time, the flame will go out.

The flame will keep burning for some time before it eventually goes out. Combustion requires oxygen. When you put the jar on top of the candle, you create a sealed environment. The oxygen inside the jar is quickly used up and the flame goes out.

If you want to see the flame burning for longer, try using a bigger jar. The bigger jar will trap more oxygen than the smaller jar and the flame will burn for a longer period of time.

6. Density Tower Experiment

This is another fun Physics experiment that you can do at home. It’s a great way to learn about density and how some liquids are heavier or denser than others.

• A clear plastic bottle with a screw-on lid
• Vegetable oil
• Food coloring
• Turkey baster
• You may also need other liquids such as rubbing alcohol, milk, dish soap, etc.

Mix some drops of food coloring into your water and mix well. Add equal parts of all the liquids into the bottle. Start with one liquid before going to the next. Each time you add a liquid, make sure it doesn’t touch the sides of the bottle.

You can start by ranking all the liquids based on how dense you think they are and then add them starting with the densest. After adding all the liquids, close the bottle and let it sit for some time.

The liquids will form layers based on their density. The densest liquid will be at the bottom and the lightest liquid will be at the top. This experiment tells us that some liquids are heavier than others.

The lighter liquid will float on top of the denser liquid because it is less dense.

7. Rising Water Experiment

The rising water experiment is a great way to learn about air pressure, heat, expansion, and contraction.

• A votive candle
• A clear glass jar
• A shallow dish
• Lighter or Matches
• Food coloring (Optional)

Pour some water into a shallow dish. You will only need just enough to cover the bottom part of the dish. You can add food coloring to the water for better visibility. Place the votive candle in the center of the jar and light it using a lighter or matches.

Immediately you light the candle, place the clear glass jar upside down on top of the shallow dish. Observe what happens to the water inside the jar.

When you light the candle, the heat from the flame will start to heat up the air inside the jar. The air inside the jar expands, but soon, the oxygen inside is depleted and the candle goes out.

The heated air inside the jar starts to cool and contracts. As the air inside the jar cools, it creates a vacuum. The atmospheric pressure outside is greater than the pressure inside the jar and this causes water to be forced up the jar.

Why Physics Experiments Are Great for Kids

Here’s why you might want to start helping your kids perform fun Physics experiments at home:

50+ Physics Project Ideas

Physics is a branch of science that mainly deals with the study of the phenomena naturally existing in the universe. To get a better understanding of the laws of nature, physicists keep themselves regularly engaged in various experiments. Interestingly, there are certain experiments and activities that one can perform easily at home to verify the existence and righteousness of various laws of the universe. Some of the basic physics project ideas are given below:

1. Balloon Car

A balloon car is one of the simplest physics project that one can make at home with the help of easily available objects. The main items required to make a balloon car include one plastic bottle, two straws, four bottle caps, one balloon, and glue. First of all, place the bottle horizontally on the table and make two pairs of grooves on the curved surface of the bottle near the opening and the base. Cut a straw in half, insert both the straw pieces into the pair of grooves. Attach four bottle caps to the ends of the straws with the help of glue. Make a grooving on the top of the plastic bottle and fix a straw in the hole in such a way that a portion of straw is present on the top, while the rest part of the straw lies inside the bottle. Attach an inflated balloon to the end of the straw that is present on the top of the bottle. When the air escaping the balloon creates air pressure on the surface, the structure tends to move forward. From this particular project, one can easily learn about air pressure, state of the matter, rotatory motion, linear motion, conversion of motion from one form to another, and various other physical parameters.

2. Catapult

A catapult is yet another simple project that one can easily make at home. To make a catapult, you need ice cream sticks, rubber bands, a bottle cap, and glue. First of all, build a stack of five ice cream sticks. Tie a rubber band on each end of the stack. Make sure that the rubber bands are properly tied and the sticks do not move. Now, take two more ice cream sticks. Place one of them on the top of the other to form a stack and attach a rubber band on one side of the stack. Slide the stack of five ice cream sticks between the stack of two ice-cream sticks. Wrap rubber band on the intersection point of the stacks to hold the catapult in place. Fix a bottle cap on the top stick with the help of glue. The catapult is ready. Place the projectile in the bottle cap, slightly push the topmost stick downwards, aim for the target, and release. It provides the user with the opportunity to learn about elasticity, tension, action-reaction force, projectile motion, and various other phenomena existing in nature.

3. Homemade Rocket

To make a homemade rocket physics project, you need an empty plastic bottle, vinegar, baking soda, three pencils, tape, a pair of scissors, and a cork. To make the structure of the rocket, attach the three pencils to the curved portion of the bottle near the top part. Make sure the pencils are placed at equal distances from each other in such a way that when the bottle is placed upside down on the ground, the mouth of the bottle does not touch the floor. The pencils should provide a rigid and stable launching pad for the model rocket. Pour some vinegar into the empty plastic bottle then add baking soda powder to it with the help of a funnel. Quickly use the cork to seal the bottle tight. Place the model rocket on the ground, move away, and observe the launch. This project helps the user understand the basic kinematics of a rocket, the chemical reaction of baking soda and vinegar, and the projectile motion of objects.

4. Baking Soda Volcano

Displaying the volcanic eruption with the help of baking soda is a popular science experiment that involves a simple set of steps. To make a baking soda volcano at home, you require dish soap, water, food colouring, white vinegar, baking soda, and a plastic bottle. First of all, make the baking soda slurry by properly mixing a portion of baking soda with an equal part of water. Now, add water, vinegar, dish soap, and a few drops of food colouring into the plastic bottle. Pour the baking soda slurry into the bottle containing the mixture. Move a few steps back and observe the volcanic eruption from a distance. The chemical eruption occurs due to a chemical reaction between the vinegar and baking soda that produces carbon dioxide gas. Carbon dioxide gas tends to spread in the surroundings because it is comparatively heavy than the other gases present in the atmosphere; however, due to the confined area of the plastic bottle, it tends to cause an eruption.

Baking Soda Volcano

5. Fountain

To make a fountain as a physics project, you require plastic containers, wooden blocks, vinyl tubing, water pump, power supply, drill machine, pebbles, stones, miniature plants, cutter, and glue. Form the base of the fountain as per your choice with the help of wooden blocks. Drill a hole at the base of one of the plastic containers and another hole on the side of the other plastic container. Pass the vinyl tubing through both holes. Glue the tube around the joints and holes. Place the containers into the wooden structure of the fountain in such a way that one of the containers is present at a height more as compared to the other container. Make a hole on the front side of the container present above the base container. Attach a small water pump at the end of the tube and connect it to the power supply. Decorate the structure with the help of pebbles, stones, paint, miniature plants, etc. Pour water into the containers and observe the water flowing just like a fountain in a miniature pond. This project would help the users understand the flow of fluids, the working of a water pump, potential energy, and kinetic energy.

6. Newton’s Cradle

Newton’s cradle is one of the most interesting structures that demonstrate the law of conservation of energy and momentum in the easiest way. To make Newton’s cradle at home for your physics project, you need ice cream sticks, a glue stick or glue gun, marbles, string, a pair of scissors, tape, and a pencil. Glue eight ice cream sticks end to end and form two separate square-shaped structures. Attach these two squares to each other with the help of four ice cream sticks in such a way that the resultant structure is shaped like a cube. Cut the string into eight equal-length pieces. Keep the length of each string approximately equal to 8 inches. Attach marbles to the centre of each piece of the string with the help of glue or a hot glue gun. Mark 6 equally spaced points on the top two parallel ice cream sticks of the cube. Place the ends of the strings on the marks and apply tape on them. Allow the marbles to hang in between. Newton cradle physics project is ready to demonstrate momentum and prove the existence of the law of conservation of energy in real life.

Newton’s Cradle

7. Balancing Scale 

A balancing scale is a prominent physics project that is capable of demonstrating weight, gravity, equilibrium, and various other concepts. To make a traditional weighing scale at home, one would need two identical paper plates, string, pencil, tape, glue, a pair of scissors, and a cloth hanger. Punch three holes in both the paper plates. Make sure the holes are close to the outer boundary of the plates. Cut out six pieces of string that are equal in length. The length of each string should be approximately equal to 2 ft. Attach one end of each string to the individual holes punched in the plates. Hold one of the paper plates and take the three strings attached to the holes grooved into it. Properly stretch the strings and tie them together in a single knot. Perform the same procedure with the other plate. Carefully, hang the paper plates on each side of a cloth hanger. Hold the cloth hanger from the hook and begin weighing the objects.

Balancing scale

8. Periscope

A periscope is a device that is used by submarine operators to see the objects above the water surface. To construct a periscope at home, you require two congruent pieces of mirror, cardboard or a PVC pipe, cutter, tape or glue. Use cardboard to make three hollow cuboids and arrange them in the shape of a real periscope. Attach the mirror glasses to the opposite corners of the structure at an angle equal to 45°. Hold one end of the periscope on eye level and look at the distant objects easily. This would help the user understand the working of mirrors and the laws of reflection.

9. Visual Doppler 

To construct a model that displays the doppler effect in real life, you require two craft papers, a ruler, a pair of scissors, tape or glue, a small toy car, blank paper and pencil or a camera. Firstly, cut out a few five-inch wide strips from the craft paper. The length of the strips should be maintained in such a way that each strip is one inch shorter than the previous one. Tape or glue the ends of the strips together to form loops. Put a toy car in the middle of the second craft paper and arrange the loops around the car in a manner that the loops do not touch each other or the car. Make sure the distance between the loops is the same. Here, the loops represent the sound waves. Take a picture of the arrangement of loops around the car when it is standing still. In case you do not have a camera, draw the impression of the arrangement of loops around the car on blank paper with the help of a pencil. Roll the toy car gently in the forward direction until it touches the loops and pushes them together. The loops present in the front get squished together and demonstrate the high pitch sound, whereas the loops at the back get spread out and tend to display the low pitch sound. Record the position of the loops after the movement of the car with the help of a camera or by drawing an impression of the scene on a blank sheet. This experiment and physical model effectively demonstrates the concept of the Doppler effect, compression, rarefaction, and the nature of sound waves.

Visual Doppler

10. Electric Motor 

An electric motor is yet another simple physics project that one can easily build at home. To make a fully functional electric motor, you require a battery, a small piece of magnet, electric wire, two paper clips, electric tape, and a knife. First of all, wrap the electrical wire around a cylindrical object such as a battery about ten to twelve times to form a loop. Now, grab the ends of the wire and tie them across the loop of the wire. Remove the insulation from the ends of the wire. Take two paper clips and stretch one end of each clip. Attach the flat end of the clips to the positive and negative terminals of the battery with the help of electrical tape. Place the loop of wire between the curved ends of the paper clips. The final step is to place the magnet under the loop of the electrical wire. Tape the magnet on the battery to hold it in position. With the help of this particular project, the user would be able to have a better understanding of magnetism, conduction of current, rotatory motion, transfer and transformation of energy, etc.

Electric Motor

11. Compass 

Building a compass at home is a prominent idea for a physics project. The materials required to build a simple compass include a sewing needle, knife, cork, magnets, and a bowl filled with water. Firstly, hold the needle and magnetise it. The magnetisation of the needle can be performed easily by stroking it with the help of a piece of magnet 30-40 times along the length. Now, flip the magnet upside down and use it to stroke the needle in a similar manner, but make sure that the magnet is moved linearly in opposite direction. Cut 1-2 cm thick portion of the cork with the help of a knife. Carefully insert the needle in the middle of the cork. The compass is ready to be tested. When the compass is placed in a bowl filled with water, it tends to point towards the North. The physics concepts that one can visualize and understand with the help of this particular project include magnetism, the magnetic field of the earth, magnetic induction, shear force, etc.

12. Marble Roller Coaster 

To make a marble roller coaster, you require a cardboard sheet, chart paper, glue or tape, and marbles. Make a roller coaster pattern full of curves and turns with the help of chart paper. Use the cardboard pieces to elevate the height accordingly. Decorate the set-up as per requirement. Make sure the elevation of the initial or start-up point is higher than the rest of the structure. Place the marble on the start point and roll it down the structure. This project would help the student or the user understand the conversion of potential energy to kinetic energy, curvilinear motion, rectilinear motion, rolling friction, etc.

13. Air Blaster

To make an air blaster, one would require a plastic bottle, a knife or cutter, a balloon, and tape or glue. Carefully cut the base of the bottle with the help of a knife or cutter. Now, cut the top portion of the balloon. Stretch the base portion of the balloon and fix it on the base of the bottle with the help of tape. Make sure there is no leakage of air from the sides. Hold the balloon attached to the bottle from the centre, pull it backwards, and release. An air vortex gets formed. Here, the user would be able to understand the working of an air vortex, the elasticity of materials, air pressure, and various other physics-related concepts.

Air Blaster

14. Potato Battery

To make a potato battery, you require a potato, a voltmeter, a galvanized nail, a piece of copper sheet or a copper coin, and two alligator connectors with clips on each end. A potato battery is capable of generating enough energy required to power a clock. Firstly, insert the galvanized nail into the potato. Make sure the potato is large enough and the nail does not go through it completely. An inch away from the nail, stick a copper coin or a piece of a copper sheet into the potato. Connect a voltmeter to the set-up and measure the voltage generated. Attach the black wire of the voltmeter to the galvanized nail and the red or yellow wire of the voltmeter to the coin. With the help of this simple physics project, the user can learn the basics of electricity, the concept of voltage, conversion of energy, etc.

Potato Battery

15. Balloon Hovercraft

To construct a balloon Hovercraft, the essential items required include a CD/DVD, a bottle cap, a balloon, glue or tape, and a pair of scissors. Firstly, groove a small hole right in the middle of the bottle cap. The diameter of the hole should be approximately equal to the diameter of a regular plastic straw. Stick the bottle cap in the centre of the CD/DVD with the help of glue or tape. Inflate the balloon, pinch it from the opening side to hold the air inside, and fix it to the boundary of the bottle cap in such a way that the air present inside the balloon can escape through the hole in the bottle cap easily.  This helps the user learn about various physics concepts such as Newton’s second law of motion, air pressure, the force of friction, the analogy of a hovercraft, etc.

Balloon Hovercraft

16. Egg in a Bottle

To construct this particular physics project model, you need a properly boiled and peeled egg, a glass bottle or container that has a narrow opening, paper, and a source of fire. Place the glass bottle on a flat and rigid surface. Light one end of the paper and place it inside the glass container. Now, place the egg on the top of the glass bottle and wait. The egg would get sucked in despite the opening of the container being narrow. The egg in a bottle physics experiment helps the user observe the relationship between atmospheric pressure, the flow of air from a region of high pressure to low pressure, combustion, and temperature.

Egg in a Bottle

17. Growing Crystals

Growing crystals is a physical phenomenon, typically referred to as crystallization, which the state of matter tends to change directly from liquid to solid form. The materials required to grow crystals at home include a glass container, distilled water, salt, a pencil, and a piece of thread. The first step to perform crystallization is to heat the distilled water up to a temperature that is a little below its boiling point. The next step is to partially fill the glass container with hot water and add salt. The quantity of salt added to the water should be enough to create a saturated solution. A saturated solution is formed when the solute is added to the solvent to the point that the solvent is not able to dissolve the solute any further. Make a loop on one end of the string and tie the other end to a pencil. Place the pencil over the container in such a way that the string gets properly immersed into the solution. Put the arrangement in a warm environment. A few days later, crystals begin to deposit on the string. This particular project helps the user get a better understanding of saturated solutions and the conversion of the state of matter from one form into another.

Growing Crystals

To make a prism, the main items required are distilled water and clear gelatin. The first step to constructing a prism is to pour the powdered gelatin into a container and add half portion of distilled water into it. Place the container on a stove and start heating the solution. Periodically stir the solution to properly dissolve gelatin in distilled water. Pour the solution into a small container and allow it to cool. Now, cut the solidified gelatin in the shape of a prism. Shine a light source from one end of the prism and observe the ray of light break into a spectrum of colours. This particular project would let the user gather knowledge about wavelengths of various colours, properties of visible light and other electromagnetic radiation, solidification process, and many more.

19. Lava Lamp

A lava lamp is yet another simple physics project that one can easily make at home with the help of easily available equipment. The materials required for this particular project include vegetable oil, glass container, food colouring, and salt.

51. Ropeway Model

To make a ropeway model, the user requires a thick cardboard sheet, a pair of scissors, glue, tape, DC motors, and a rope or string. First of all cut four rectangle shape cardboard strips of equal dimensions. Attach a dc motor on one end of the rectangular strip. Cover the motor by forming a cuboid shape using cardboard around it. Form a closed electronic circuit by connecting a switch to the motor and a battery clip. Glue the switch and the battery on the top of the cuboid. Cut three circles out of the cardboard sheet, neatly stack them, and glue them together in place. Make sure that the circle present in the middle has a smaller diameter than the diameter of the two circles present on the boundary. Drill a hole in the middle of the three circles and fix it over the motor shaft. Make another cuboid box and circles with the help of cardboard having the same dimensions as the previous ones. Place both the cuboids opposite to each other and properly glue them in place. Make sure the height of the circles present on the top of the cuboids is the same. Wrap a string around the inner circle of both structures. The string should have a sufficient amount of tension in it. Attach two small cardboard boxes to the string and turn on the switch. The motor begins to rotate the shaft. The shaft transfers rotatory motion to the circular structure, which in turn causes the string to move. This particular project is helpful as it explains various physics-related concepts such as the working of a motor, transfer of momentum, inertia, rotary motion, and tension.

52. Hand Water Pump 

To make a hand water pump at home, you need a 60ml syringe, a 5ml syringe, copper tubes (5mm and 8mm), iron strips, foam valve for water pumps, bearing balls, iron nail, washer, plier, drill machine, cutter, nut bolts, and a plastic container. The first step is to remove the plunger from the syringe. Now, cut the foam valve in the shape of a circle that has a diameter equal to that of the barrel. Put the foam valve into the empty barrel of the syringe. Make sure that the valve is able to move up and down with ease. Now, remove the rubber part attached to the plunger and replace it with the valve. Now, drill two holes located opposite to each other on the top of the plunger rod. Cut the plunger into two halves. Take a copper rod and compress its ends with the help of a plier. Now, drill a small hole on one end of the copper rod and two holes on the other end of the rod. Attach the rod to the plunger by drilling holes and inserting nuts and bolts through the holes present on the copper rod and the plunger. Take a metal strip and wrap it around the curved surface of the syringe barrel. Leave a few inches on both the ends of the metal strip. Align the ends of the metal strip along a straight imaginary line and drill two holes through them. The next step is to take two pieces of metal strip, fold them along the length, and drill a hole at both ends of each metal strip. Use a grinder to curve the shape of the ends of the metal strips. Attach the curved metal strip to the surface of the syringe barrel and fix it in place with the help of nuts and bolts. Make a small hole in the top corner of the syringe barrel. Take a 5ml syringe and remove its plunger rod. Cut the front portion of the barrel and glue it over the hole made on the curved surface of the 60ml syringe barrel. Now, take another copper tube. Make a hole on the end of the tube and another hole a few inches away from the same end. Take the middle portion of the foam valve and cut it in such a way that you have two circles. Insert a washer in between both the circles and pass an iron nail through the arrangement. Place it into the 60ml syringe barrel. Now, insert the plunger that contains the foam valve and is connected to the iron rod into the 60ml syringe barrel. Drop a bearing over the plunger. Seal the top of the barrel with the help of a circular plastic cut out. Attach the two metal strips and the copper rods together with the help of nuts and bolts. Use another nut and bolt to fix the curved rectangle shape metal strip to the copper rod. Pour water into the plastic container and dip the hand pump into it. Fix the handpump over the lid of the container with the help of a hot glue gun. Test the working of the project. This particular project would help the user understand the fluid mechanics, pressure, positive displacement principle, kinetic energy, mechanical energy, movement of fluids from a region of high pressure to a region of low pressure, etc.

53. Bubble Machine 

A bubble machine is yet another example of a simple physics project. To make a bubble machine at home, you require a plastic tube, a pair of scissors, plastic straws, a marker, tape, bottle cap, DC motors, battery, battery holder, propeller, USB, USB charger, electrical tape, and cardboard box. First of all, use a marker to make markings on the plastic tube. Make sure the markings are located at equal distances from each other. Now cut the tube along the marks to obtain congruent hollow cylindrical pieces. In a similar manner, cut the straws and obtain equal length hollow cylindrical pieces. Attach the straw pieces to each other in the shape of a star. Now, attach the plastic tube pieces to the end of the straw pieces arranged in the form of a star. Glue a bottle cap to the centre of the star-shaped pattern to form the bubble wheel. Take a DC motor and connect it to a battery holder. Fix the motor shaft to the bottle cap. The next step is to take a propeller and cut it into the desired size. Take another DC motor. Connect the motor to a USB charger. Attach the propeller to the motor shaft. Fix the motor on a cardboard box. Form the soap solution by dissolving shampoo, liquid dish wash, or liquid handwash into water. Pour this soap solution into a plastic container. Fix the motors on the lid of a plastic container. Make sure the motor connected to the plastic straw and tubes is fixed over the lid of the plastic container in such a way that the star pattern is properly immersed into the liquid present inside the container and is able to move easily. The propeller should be placed in such a way that the air circulated by the propeller directly passes through the plastic tube pieces. Check the motor connections and place an electrical tape over the joints. Turn on the power supply and test the working of the project. This helps the user understand the working of motors, propellers, circulation of air, surface tension, formation of bubbles, and the reason behind the tendency of the bubbles to maintain a spherical shape.

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!

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:

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:

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.

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.

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!
