background

Have you ever seen a sporting event played on a big field at night? On many fields, there are only a few really bright lights placed around the field. Each light casts a shadow. So each player has maybe four shadows, extending in different directions.

To make things easier, the player in this activity appears as a red cone. And there are four lights—one at each corner of the field. So, the player standing on the field might look like this:

From an overhead view, the cone will look like a circle, and each shadow will be a triangle. A "blimp's eye view"—from directly overhead—might look like this:

Now here's your task: When you are ready to figure out why the shadows behave the way they do select Go!

Go!
