    Make a simple paper helicopter, like in the diagram to the right:

    Now create an investigation that tells you how to design your
    helicopter to do the following things:
    a) spin quickly, or spin slowly
    b) drop slowly;
    c) different combinations of the options above.
    Try changing things like the length of the propeller arms, the width of the propeller arms, and the weight of the body. What happens?

    Hold a helicopter drop contest. Find a safe place from which to drop your helicopters and try to make them land in a target circle.
