Spotting the Moon in the sky is like finding a treasure--unexpected and beautiful. When children look for the Moon in the sky, they don't know where to look. The Moon is far away and most easily observed at a time when most young children are sleeping. Because direct contact isn't possible, adults have to be creative in how they help children learn about the Moon. Teachers can help young children begin to understand one of the reasons for the patterns one sees on the Moon's surface by modeling the process that creates impact craters. This article describes a simple crater formation activity. For younger children, this activity teaches about using models to understand Earth Science processes. Older children may also begin to think about force by comparing craters made by different weight balls, and the push the children give them. (Contains 2 online resources.)
