This Shockwave tutorial for Grades 5-8 explores properties of gases in an interactive, game-like environment. It was designed to help students build concepts about mass, volume, and density of gases. Activity 1 dispels the myth that "gas is weightless" (a commonly-held misconception among secondary students). Activity 2 demonstrates density as students place helium, air, water, and oil in a virtual cylinder. Activity 3 illustrates what happens at the molecular level as gases are heated or cooled or undergo pressure changes.

4. The Physical Setting
4D. The Structure of Matter
6-8: 4D/M3ab. Atoms and molecules are perpetually in motion. Increased temperature means greater average energy of motion, so most substances expand when heated.
6-8: 4D/M8. Most substances can exist as a solid, liquid, or gas depending on temperature.
6-8: 4D/M10. A substance has characteristic properties such as density, a boiling point, and solubility, all of which are independent of the amount of the substance and can be used to identify it.

Topic: Heat and Temperature Unit Title: The Relationship Between Heat and Temperature
Lots of bang for the buck in this simple Shockwave tutorial. Part 1 helps dispel the myth that "gas is weightless". Part 2 demonstrates density of gases as students place air, water, helium, and oil in a virtual cylinder. Part 3 explores what happens at the molecular level as gases are heated/cooled.
