The Science You Actually Need

What a Machine Really Does

Levers, Ramps, Wheels — Easing the Effort

Pulleys and Wedges

Check Your Understanding — The Science

The simple-machine science every teacher needs — what a machine really is, how levers and ramps make work easier, and how pulleys and wedges work — in plain, preschool-honest language.

You don't need an engineering degree — you need a handful of true, simple ideas you can hold in your head while a child hands you a question. This module gives you exactly that.
