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

Serc: Mn Step: Sink or Float? Inquiry Investigation
For this activity, students make predictions about whether different objects float or sink, then test them. They are asked to record their observations and results for each, and compare their results to others'.

Serc: Mn Step: Who Is on Top?
Students investigate density in this activity when they try to find out if oil or water has a higher density.

The Science House: Daffy Densities
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.

The Science House: Red, White, and Blue Ii
This colorful demonstration illustrates the rule, "likes dissolve likes," by combining three, immiscible liquids to create a density column." Teacher notes provide background information.
