Fun With Physics! 10 DIY Physics Projects For Kids

Physics is fun. No, really, hear us out! We've put together a list of really cool projects to help your child gain a hands on understanding of physics fundamentals like inertia, momentum, pressure, and leverage. Witness the explosive effects of pressure by launching your own rocket. Build a pulley system using string and a broom. Watch confetti dance to invisible sound waves, and much more!

  • Visual aid of how to complete Spinning Sculptures

    Use the power of electromagnetism to create your own spinning sculpture! 

  • Visual aid of how to complete Dancing Sprinkles

    Ever wondered if you can see sound? Well, in this experiment, you’ll use a Ziploc® brand sandwich bag to turn music into motion. It works because sound is a wave: a vibration that travels through the air (or another material) like a wave travels through water. Normally, we only hear these vibrations, and we can't see them. But by using the vibrations to make sprinkles dance, you’ll be able to see sound waves!

    How to Make a Pendulum Wave Toy

    A pendulum is a hanging weight that swings back and forth, like the swinging arm on a grandfather clock or a swing on a playground. When you pull a swing - or any pendulum - up to one side, gravity tugs it back down. But since the swing is attached by a rope or chain, it doesn’t just drop to the ground. Instead, it swings back and forth, over and over.

    But what happens when you have a bunch of different-sized pendulums swinging together? Make this mesmerizing pendulum wave toy to find out!

  • Visual aid of how to complete Pressure Bottle Rocket

    Water squirters work by pressurizing reservoirs of water with air. As you pump the squirter, it gradually adds air to the reservoir, increasing the pressure. When you pull the trigger, the pressure is allowed to release and a stream of water shoots out!

    In this DIY project, we'll learn how to use the exact sample principles found in water squirters to launch a water rocket sky-high! Follow along with these simple steps and you'll be blasting off in no time.

  • Visual aid of how to complete Cartesian Diver
    Cartesian Diver

    (Ages 5-11)

    Explore the science behind density and pressure with this DIY bottle diver. Make a scuba diver toy and watch it sink or float by squeezing the bottle.

  • Visual aid of how to complete Paper Airplane Launcher

    Take your paper airplanes to new heights by making a motorized launcher for them.

  • Visual aid of how to complete Levitating Slinky

    Are slinkies magical floating toys or do they somehow follow the laws of physics? Grab your favorite timeless fidget toy, head outside, and find out for yourself!

  • Visual aid of how to complete Newton's Tower
    Newton's Tower

    (Ages 5-11)

    Use excess office supplies to experiment with and learn about inertia! 

  • Visual aid of how to complete Compound Pulley
    Compound Pulley

    (Ages 9-16)

    This setup is a compound pulley, which combine both fixed and moveable pulleys to increase the mechanical advantage.

    In a pulley system, a wheel's job is to let the rope move freely. Here, this set up works with no wheels. The broom can act as the wheel since it's low-friction enough that the rope can easily move over it.

  • Visual aid of how to complete Rubber Band Helicopter

    Learn about helicopters by making a rubber band powered flying toy!
