Discuss with your partner as many possible reasons why they used a wheel instead of a screw driver to turn the screw. Record your list of reasons in your lab packet.

We will now prepare to repeat the Wheel & Axle lab. This time, you should change the size of the wheel.
Leave the thread density the same as you test several size wheels.
The wheel radius can be changed from a 50 cm radius to as large as a 100 cm radius.
