off of a teeter toter:

• compute your machine's mechanical advantage and
• give one example using sample data of how the mechanical advantage is exhibited (show how you trade force for distance using actual or theoretical numbers)

Regardless of how you choose to create your Scientific Model, it should:

1. Contain all necessary parts and components of the system you are modeling
2. Specify each part and component and its respective function. (You may create a key with parts and functions for this step)
