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?
thanks, Paulo

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 :-).

Check out ODE for Squeak:

(scroll down a bit to the Etoys section)

I couldn't get ForceField.pr or Hinge.pr to load in SqueakPlugin or in 3.7 image (dangling references to ODE* classes). Does this mean the demos failed to make it to mainstream Etoys image?
I got 404-ed by SqueakFesta link and the complete zip was about 11MB. I gave up.

ODECo is not in the etoys image. You also need the ODE plugin to make it work.

I forgot that I moved those files. The most easy way to play with ODECo is just to download http://metatoys.org/pub/ODECo-2004-08-06.zip
Or, if you prefer, there is a sar file which you can load into Squeak3.7 or 3.8 (I haven't tested on 3.9 yet.) http://map.squeak.org/accountbyid/4f38fede-e58f-48f0-bf41-0c109f9441e5/files...
This sar file will download appropriate plugin automatically. If you want to use Squeakland image, you have to download the plugin by yourself from http://languagegame.org:8080/ggame/15. (because this sar installer downloads it to FileDirectory default where it is my squeak folder in squeakland image).
Thank you!

Great!
A huge work to be done (if in Squeak) but it can be fun..;-)
thanks for the link.
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.

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.
