Why Lesson Planet?
It's not easy to find fabulous physics lesson plans, but School Power Naturally has put together a series of them. In this particular lesson, high schoolers learn about the structure and functioning of photovoltaic cells. They construct a giant PV cell model as a class and throw wads of paper across it to demonstrate photons becoming electrons. Of course, you will explain the relationship. Plenty of background information is provided to support you, and a student worksheet further explains these concepts.
