Science Is Fun: Bowling Balls Float or Sink?
In this experiment, you test whether two different bowling balls will float or sink, then determine the density of each of the balls to see if they are less than that of water.

Serc: Investigating the Effects of Density and Volume of a Cartesian Diver
In this lesson, students will investigate why the Cartesian diver dives and rises in a 2 liter bottle. They will also, through their own discovery, come up with a question and then change one variable and record their results. Students...
