Lesson 5.1.2 - Density

In lesson 2, we will be studying density, an important physical property of matter. The property of density measures the amount of matter in a fixed volume. An objects density shows the relationship between the mass and volume of an object or substance. Density is measured in grams per cubic centimeter. This means that for a substance with a density of 1g/cc, one cubic centimeter of the substance will have a mass of one gram. In a very dense material, the molecules will be packed tightly together; but in a less dense material, there will be more space between molecules. In this lesson, we will compare the density of a variety of different materials, as well as calculate the density of several substances. Using substances with known densities, we will also predict and test the buoyancy of those substances.
