Soccer Ball Kick

I'm Dana, and I get my kicks playing soccer. I'm a strong player, but I want to figure out how to really boot the ball the length of the field! My question: if your legs are bigger, can you always kick the ball farther? For my DragonflyTV investigation, I invented a machine to answer this question. How would you investigate this question?

Brainstorm with other students ways to build a machine that can kick a soccer ball. Draw a design of your machine in your notebook and share it with the class. You can also go to Soccer Ball to see Dana's machine and find out what she discovered.
