PAPER HELICOPTER

PAPER CLIPS

The Clamp is going to make the ruler stay in place so when we drop the Helicopter it will be dropped at the same height each time. The reason why we couldn’t have someone to hold it up is because they are going to be shaky and might move positions

The Stopwatch is to time how long the Helicopter takes to fall. If we don’t use a stopwatch and a human being is counting how long the Helicopter takes to fall, the person could be counting to slow or to fast.

The Ruler is to measure where we are dropping it from each time. If we don’t use a Ruler then we won’t be able to remember the height we are dropping the Helicopter from.

The Paper Helicopter is a model of real Helicopter to show how the it’s going to work.

The paper clips are to make the Helicopter travel in one direction and stop it from traveling side to side.
