Build a simple machine

In this project lesson you will design and build your own simple machine. The goal is to use what you know about levers, pulleys, ramps, and wheels to make a real job easier. A good simple-machine project does work with less effort than your bare hands could do alone.

What this lesson teaches

1Plan a simple-machine project that solves a real lifting or moving problem
2Identify the load, effort, and fulcrum or pivot in your design
3Build a working prototype using everyday materials
4Test your machine, record what happens, and improve the design
