Students explore force and friction using simple machines. Students design their own simple machines and make compound machines to demonstrate how they make work easier.

Major Concepts & Big Ideas:

1. What is a force and what causes a force to change?
2. How does the amount of force change as you move objects over different surfaces?
3. How do simple machines affect force?
4. Design and build a compound machine to solve a problem.
5. Where can you find simple machines in your environment?
