Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

An introduction to density, mass, and volume with links to related books and activities.

In this lab experiment, students will use 4 solids and 6 liquids to create colorful, layered rows demonstrating that less dense materials will float on top of the more dense materials.

Deepen the students' understanding of density by constructing a simple hydrometer that can be used to compare the densities of different solutions.

Demonstrate buoyancy with raisins and club soda.
