Density Curriculum

Section 2—Lesson 7: Do Gases Have Density?

Understanding Goals

Subject Matter

  • Gases are matter.
  • Gases take up space.
  • Gases have mass.
  • Gases have density. Density is the relationship between volume and mass so all matter has density.

Causality

  • Gases are non-obvious in many respects. This makes it difficult to realize that they have properties such as density.
