We went to the science lab and used a sense of sound to figure out the objects in six different bags. The students passed the bags around, shook each one, and then drew their prediction in their science journal. At the end, the students shared their predictions and we revealed what was in each bag. One bag had cotton balls, so we discussed how some objects make very soft sounds. The objects we used were cotton balls, coins, pet mulch, Legos, sand, and buttons.
