Ask your child about today's science class. As part of our investigation into light, the children saw how light can project an image. To demonstrate this, we darkened the room except for a small hole by a window. The light entering through that hole then projects an image of the outside onto a screen. The technique is called Camera Obscura. A brief video showing one working (better than ours did) can be seen by following this link: http://ngm.nationalgeographic.com/2011/05/camera-obscura/camera-obscura-video
