We started our Moon unit with a KWL chart. The students wrote what they know and what they want to know about the moon. As we worked through the unit we filled in the "L" with what we have learned and checked off the questions under the "W" as we answered them. We are still is doing this unit so our KWL chart is still in the works.
We use BrainPopJr.com, NASA kids, Youtube, and many books to learn more about the moon. These are some of the books we read.
