Online Physics Games

“Xavier Enigma’s Next Physics Game. Draw your own shapes and let gravity take its toll. Circles are near impossible, but levers are easy.”

My 9-year-old loves these. The one we are most familiar with is Crayon Physics, a freeware game.

“You play with crayons and physics. The goal of the game is to move the red ball so that it collects the stars. You can cause the red ball to move by drawing physical objects. “

HOW TO - Make a simple pulley

The Canada Science and Technology Museum has a page on Simple Machines (Pulleys and Gears) which includes:

• Background information on simple machines in a FAQ format
• A lesson plan, which you can use to guide your homeschooler or unschooler
• Instructions on making a simple pulley (shown at the right)

Keep an eye out for simple machines everywhere (the world is your school), like in the playground.

The site also links to some relevant sites on simple machines:

• The Franklin Institute - Simple Machines
• Work is Simple with Simple Machines
• The Simple Machines Learning Site
