This week the 7th age scientists learned about shadows. We talked about when we see shadows, and how the shape of a shadow changes throughout the course of a day. In this experiment we used flashlights, modeling clay, and a straw. We shined the flashlight on the straw (the modeling clay was used as a support for the straw), and took turns tracing a shadow into our lab books.
You can try this experiment at home! You can use craft sticks or even utensils in place of the straw. How can you make a long shadow? How can you make a short shadow? Does the position of the flashlight affect how the shadow looks?
