This boy is looking for his rainbow as he holds a prism in the sunlight. I'm lucky to have a room with one wall of windows!
I was showing the kids the difference between a Concave lens and a convex lens. I was able to "shrink" the class with this concave lens.
Here the class is multiplied in a homemade Kaleidoscope (made of 3 plastic mirror strips taped together in a triangle).
