Throughout the course of the semester, one of our Interns has been exploring light with the children. She brought in several types of light sources like lamps, flashlights, and the overhead projector. She also brought in some LED lights that the children could explore in various ways. Since the children have also been interested in water, she decided to combine the two so the children could see how the lights look in the water.
The children were excited about being able to directly manipulate where the light goes. They also seemed to try different things with the lights in the water table, like stacking the lights and trying to cover them with their hands to watch how the light changed.
