Investigate & play: 6 free science activities

SimpleMachinesbyTinybop-2wheel

In our Simple Machines app, kids play with a wheel and axle, lever, pulleys, screws, wedges, and an inclined plane. They can test and modify each one to figure out how they work by toppling a castle, lifting sloshing fish tanks in the air, whizzing through an obstacle course, and more.

Playing with each machine in the app is, of course, fun but here are six activities to bring playful learning into the real world, too.
