Students will create water samples with different temperatures and salinities, and then compare their sample with a partner’s in a tank. Once they finish observing the behavior of their samples, they will make some density calculations and explain their observations in terms of density. Discuss as a group what effects changing properties such as temperature […]

Does a can of soda float? Does salt water really make that much difference? What’s a Plimsoll mark? Buoyancy can be a difficult concept for students. It’s all about density! With this hands-on introduction to teaching buoyancy from the Bridge website and COSEE-NOW, students work through activities and demonstrations that use online resources and ocean […]
You too can use ocean observing system data despite teaching a standards-based curriculum!
