6th graders were able to participate in a STEM science lesson dealing with density. In this lesson, students stretched a piece of black fabric, and then the teacher set balls with different densities on the fabric one by one. Students watched to see how far the fabric stretched down when each ball was placed on the fabric. The students especially loved the difference of placing the soccer ball and bowling ball on the fabric. They determined that because the bowling ball was solid and the soccer ball was filled with air, that the bowling ball must be more dense.
