Science Fair Projects for 9th Grade

These science fair projects for 9th grade are perfect for older kids to explore advanced science concepts and tinker with some more exciting materials.

  • 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 Flying Teabag
    Flying Teabag

    (Ages 7-16)

    Make a tea bag fly with heat! The flying tea bag experiment is a similar concept to a hot air balloon, but you can do it right at home. This project is simple to create, but impressive to kids and adults alike!

  • Visual aid of how to complete Flaming Torch
    Flaming Torch

    (Ages 9-16)

    Create a whirling fire torch of your own. The flames spin upwards into a vortex from the rising heat and wind. Follow along to safely create a whirling fire torch yourself!

  • Give this experiment a try, and see how many paper clips you can pick up with your electromagnet!

    Unlike the magnets that are used on refrigerators, electromagnets are magnets can be turned on and off depending on the flow of electricity. The electricity that flows through the wire allows the molecules on the in the nail to attract to certain things.

  • Visual aid of how to complete Rubber Band Racer

    I’m a huge race car fan, so when we started experimenting with wheeled vehicles in our kid testing lab, I knew just what I wanted to create! Using simple household materials and tools, it was super easy to create a rubber band-powered racer. The steps below require some adult assistance as we used an electric drill and a hot glue gun, but our kid testers were happy to help with the other steps -- and of course experiment with wheels, rubber bands, and different surfaces to see how fast their racers could go!

Get inspired!
