The Magical Diving Sub
K, 1-2, 3-5
Grades K-6: In this two-day exploration, students use their background knowledge of how scientists work to discuss and predict if a given object will sink or float. They record these predictions on a data sheet. They then test the objects and organize them into floating/sinking groups. Students also observe the floating and sinking of a toy submarine and infer what is causing the sub to float or sink.
