After reading, How Do You Lift a Lion? by Robert E. Wells students were given a challenge to make a pulley to lift a "lion". The mission was to lift a lion at least three feet off the ground using only the following items.
- craft sticks
- tape
- string
- scissors
- pulley
- "lion" this could be anything you can lift
Questions to consider:
What is the load you are lifting?
What force is working against you?
What will you use for a platform?
How will you keep the "lion" on it?
What will do the work for you?

Using a rock as a "lion"
