The hypothesis is that Newton's Third Law of Motion can be demonstrated with escaping air as the action force.

You will construct a balloon-powered rocket car by drawing a rectangle and four circles on a Styrofoam meat tray, inflating a balloon and attaching it to a flexi-straw, taping the straw to the car, and pushing pins into the circles and rectangle.

You will need 4 pins, a Styrofoam meat tray, cellophane tape, a flexi-straw, scissors, a drawing compass, a marker pen, a small party balloon, and a ruler.

After constructing the car, you can observe that it rolls across the floor due to the escaping air from the balloon, demonstrating Newton's Third Law of Motion. You can also design your own car and hold car distance trials to measure and chart the distances each car travels.

This science project is interesting and unique because it allows students to construct their own rocket car and observe the effects of Newton's Third Law of Motion in action.

Experiment variations to consider include using different materials for the car, such as Styrofoam coffee cups, and testing different sizes of wheels.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
