Simple Machines, a screen from the game

What your child learns

  • Levers: weight × distance
  • Pulleys share the load between ropes
  • Ramps: longer is easier

How to play

Put the box where the seesaw balances, choose the pulley that lets Owlie lift the crate, and pick a ramp long enough to push the cart up. Four right answers finish a level.

Levels

  1. Level 1Balance the lever.
  2. Level 2Which pulley lifts it?
  3. Level 3Which ramp is long enough?

A tip for parents

Try it at the playground: two children of different weights on a seesaw.

Works on phones, tablets and computers, with nothing to install. No ads and no tracking.
