Second grade students combined their knowledge of force and motion with measurement to create models of moon craters. The "meteors" they used were of two different sizes and tested at two different speeds. After creating the craters they measured the size of the craters to the nearest centimeter. Here is a link to a slow-mo video of crater creation.

The students continued their learning about objects in the sky by studying moon phases. After watching a Brain Pop Jr. video on the moon, the students used a moon calendar to determine and draw a picture of the moon phase on dates of their choice. The second graders really enjoyed making constellation viewers as a way to learn about the stars. They know why some stars appear brighter than others, and are beginning to identify some constellations.
