Ms. Alison thinks these explorations are examples of Henry's best work, because they show his ability to think and solve problems that peak his curiosity.
Here is Henry is playing with a flashlight and his friends in the Dark Tent, as well as exploring the projector:
"The boys showed great interest in the concept of 'How is it changing?' They noticed some interesting phenomenon such as when light goes in different directions, the shadow changes its position accordingly. And when light comes from different distances, the shadow may get bigger or smaller. Also, when you put a flashlight in front of your tummy you can't see a shadow because the light is blocked. They also have lots of theories about lightbulbs. They believe that electricity is powerful and important. It gives us light and makes machines run. Most importantly, we can watch TV!"
