Since jr scientist A has quite an interest in outer space, we decided to investigate why the moon looks like it does. I ran across this experiment in Pop Bottle Science (yes, I know, this has nothing to do with pop bottles). We looked at some pictures of the moon with all its craters and I asked jr. scientist A where he thought all those bumps came from. He didn't have any idea so we got out a container and some flour and made a mock lunar surface. Then I rolled a piece of play-dough into a little ball and threw it into the flour resulting in a mock crater in our mock lunar surface. Jr. scientist A had lots of fun making craters and it seemed to really make sense to him. It was a great way to explain an otherwise difficult to conceptualize idea (I wish I could take credit for coming up with the experiment!)
