This is a set of nine experiments that introduce students to the concept of density and provide practice in measuring it. Many students have difficulty understanding density as a quantity derived from mass and volume. Learners often enter college with deeply-entrenched misconceptions, such as the erroneous idea that gases have no mass. These classroom labs were developed to promote correct ideas of density, and to demonstrate differing techniques for measuring density in solids, liquids, and gases.

Specific topics include: density of regular solid shapes, measuring density and weight of liquids, measuring the average density of a student, weighing a sample of air, and more.
