Grades 3 and Up

Well all know that certain things float in water, while others sink. Why?

Using a water tank, this presentation explores the principles of density and buoyancy.

Scientists seem to enjoy dropping stuff into water to see if it will sink or float, so together let's find the answers to some age old questions: Is it easier to float in the ocean or in a pool? Why? Oil and water don't mix....really?

Participants will get their hands on science to make a density column and take home the materials to make their own Cartesian diver!
