Thanks, Alan
Great idea. I should use some (accel. plotting) on my "experiment" (attached). it can be opened w/ version 3.8. I'm writing a companion document - a step-by-step like in "Powerful Ideas" book. As soon I get it working better and with those "enhancements", I send it to the list.
My ultimate goal is to put kids to think a Newton's Cradle as an energy transmission device.
cheers, Paulo

But consider this Etoy (run in the OLPC version of Etoys) and also take a look at Takashi Yamamiya's site and work over the last few years.

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 :-).
