Individual Project #4
This project will show how the rotation of a propeller causes thrust.
Note: material item #1 has to be shaped like a propeller or you can buy a propeller at a toy store or hobby shop.
First you'll have to have your teacher drill a hole in the balsa wood. Attach the dowel to the propeller. Next, hold the dowel loosely in one hand and rapidly twist the dowel with the other hand.
A rapid twist causes the thrust necessary to make the propeller move foreword.
