Oceanographers participate in a memorable hands on experience about buoyancy. They build a model of a submersible using a plastic bottle and a balloon. Afterward, they answer assessment questions. An answer key and some terrific...

Students watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.

Young scholars build a model of a submersible that will allow them to explore ballasts and how they operate.  For this hands on lesson students participate in an activity that shows them how to control buoyancy.
