Hi all,
Following "Powerful Ideas..." - the great book by Kim & BJ, I'm trying to introduce the concept of mass (or weight, for simplicity of kid's undestanding), to enhance a project about pendula and energy.
Any ideas?
Excellent idea. This would allow kids to simulate planets, satellites, collisions and so on.
Sodaconstructor (http://www.sodaplay.com) uses just three objects
- mass
(fixed or free), a spring (a stretchable line connecting two masses) and a muscle (line connecting masses that stretches and shrinks periodically) - and then four controls - gravity, friction, elasticity and an activation wave for a muscle - to create very interesting "creatures". Be warned, this is very addictive :-).
