Hello everyone,

Has anyone done any programming about light and color that involves  
kids running around acting out photons or something similar? I'm  
looking for any active games or demonstrations that have to do with  
light and its properties. (I'm also on the lookout for ANY activities  
about light and color, so if you have any really great ones I'd love  
to hear about them, even if they don't fit this category.) These  
would eventually be related to astronomy, i.e. what we can tell from  
the light that comes from distant objects, how we can tell that, and  
about the tools that allow us to do that.

I've heard of examples where each kid is a different color photon and  
when they run into an object, only the one with the color of the  
object reflects back; the others stick. I also remember doing  
something in my high school physics class where we all linked arms  
and walked forward as a wave front. When one end of the line crossed  
the barrier marking a new material, they slowed down, while the rest  
of us continued at the same speed, demonstrating refraction. I'm  
looking for ideas along these lines.

Thanks,
Anna Hurst
