Propulsion - prop size   (Lesson Plan/Activity)
In this activity students explore how a propeller's size can influence the amount of propulsion they will get. They will build a simple set-up where they can record how many revolutions a certain propeller makes in a set time. This can be compared to the same set-up with different sized propellers. ...
