I am so impressed with the Discover and Do Science Experiment curriculum. My kids have done another really cool experiment following the video instructions. This week they made a flashing switch and a lighthouse.
this and then the pencil was turned. As the pencil spun in a circle the wires touched the foil and then the cardboard, causing the circuit to be complete and then incomplete and resulting in the flashing effect of the light.
Then they placed the light on top of an empty paper towel roll decorated to look like a lighthouse and the lighthouse was complete.
