Birch Aquarium at Scripps Institution of Oceanography

Guests will test, build, and design their own Cartesian diver using principles of buoyancy in relation to fish. They will be able to define and understand the concept of buoyancy, explain how a fish moves up and down in the water column, and engage in the scientific process. The activity will have fish and shark diagrams to show how these animals stay buoyant, bins filled with water to test buoyancy of "divers", and the opportunity for guests to design and test their own cartesian divers.
