Because different liquids have different properties, density also differs. For this lesson from the Illinois Institute of Technology, students will calculate densities of water, dish-washing detergent, cooking oil, and other liquids.

Students determine whether a liquid will sink or float in water by comparing its density to the density of water.

This experiment allows you to dramatically demonstrate the different densities of five different common household liquids.

A simple lab experiment for students to find the density of two solids and a liquid (does not use water displacement). Note that number 1d should not state "weighs" since mass is being found.

Learn how the molecular movement in different temperature water affects the density of the liquid.

Demonstrate the effect that dissolving different amounts of salt in water has on the density of the liquid.

This site from Suzy's World explores how and why certain liquids mix better than others. Content includes fun facts and a classroom experiment. This site also includes links to additional information on related subjects.

This colorful demonstration illustrates the rule, "likes dissolve likes," by combining three, immiscible liquids to create a density column." Teacher notes provide background information.

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

Learn about the layers of the Earth.

Of course it can, you say: ice is water and ice floats. And you're right. But we're talking about water in the liquid phase Can liquid water float on water? The goal of this project is to investigate what happens to layers of water with...

Investigate the science behind this age old question. Find out the role density and polarity play in the liquids.
