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.

Density is the ratio of mass to volume. Density will be introduced to students by a demonstration of coke verses diet coke. The teacher will then solve density problems for the students on the board. The class will then complete a lab on...

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.

A simple lab activity to demonstrate that ocean currents are influenced by changes in water density.

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