Good luck and have fun.

thanks Mark,

this is exactly what I want to do with my students. The reason of doing these expt is, when teaching them gravitation, all the distances are given. They will ask how these data come from, and I think this is the most interesting part of the lesson instead of applying fomulaes.

I wish to find a school in west aust. to work together, hope that there r some physics/astro teachers would come together and have fun!! but I know nobody here, and that is why I ask this question.

The transition of venus is coming, so, if there is anyone love this idea,

JUST JOIN THE PARTY HERE!!!

I hope someone can understand the meaning of this game, and show the students the real fun of physics is!!

thank you Mark.
