Physics and Engineering Projects

Physics is the natural science that studies matter, motion and energy through space and time, including the relation, if any, to energy and force.

With these Physical Science & Engineering Projects, you’ll be able to discover laws of force and motion, build and construct models and machines, and more! Experience the force of magnetism, the thrust of pressurized gas, or the power of the sun in hands-on activities like building a balloon rocket car.

Check out ourForce & Motion pagefor more hands-on project ideas with the Physics Workshop or Amazing Bridges kits, fascinating books, and more!

Take your next fireworks or light show to the next level with DIY fireworks (or rainbow) glasses made from diffraction grating.

School’s out! Now what? Make it the best summer yet with these 50 simple science projects to do at home.
In this experiment, we will make a homopolar motor! To make a simple motor (homopolar motor) that doubles as a work of art you will need three things – a battery, magnet, and wire. Use one of our neodymium magnets to power the spinning wire motor. What You Will Need: 1 neodymium disc magnet (0.5” […]
Print out this page on a sheet of heavy paper or cardstock. Kids can color the pictures and cut out the squares to make a matching game. Half of the squares show a way to use solar energy as an alternative to the picture shown on the other squares. Place all the squares face down […]
Spring break is here! What will you do with your time off? Perhaps you’re looking forward to a family vacation, or a few days of down time at home. Either way, find a quick and easy project that’s sure to put a sparkle in the eye of any science lover, or win over a reluctant […]
Use the Sink or Float Worksheet with the “Sink or Float?” science project to encourage kids to make predictions, perform tests, and record their results. This project is perfect for indoor discovery – especially in colder months! Put a towel under a large container of water for easy clean up. If the weather is nice, […]

Find physics science fair project ideas about magnetism, electricity, energy and solar power, and more.

These classic science experiments use mostly household items, ideal for at-home activities. Make slime, super-bubbles, a solar oven, and more!

Have you ever wondered about the science behind flight? The basic principles of flight, which include many elementary physics concepts, can be easily observed in the structure of an airplane.

Build a model car powered by a rubber band.

Build your own circuit and see how it works with this project.

捕鼠器适合任何超过着凉了吗g mice? Actually, yes. Mousetraps can be used to power a car! This project results in a simple mousetrap car. It probably won’t go very far or fast, but you can see how stored, potential energy is converted into kinetic energy. When you’re finished with this project, you can […]
