Puriri team is investigating Light, Shadow and Reflection as a science topic. So far, we have observed shadows of revolving 3D objects, shadow puppets, and our own shadows from the sun.
Here, we are exploring triangular
prisms,
convex mirrors (bulges outward), and
concave mirrors (bulges inward). The sun wasn't quite bright enough to see really obvious results, but we still noticed the differences between the mirrors.
We gave up on the sun and moved inside to the projector.
We have achieved Rainbow (a spectrum at least)!
