This multimedia lesson by the American Chemical Society helps students understand that gases are matter with measurable mass, a topic of frequent misconception in the middle grades. Students compare the mass of a basketball before and after it is inflated, they explore the mass of a can of compressed air before and after air is expelled, and they consider how heating and cooling affect molecular motion in gases. Teachers have access to complete lesson plans for all the experiments, student activity guide sheets with answer keys, videos that depict how to do the demonstrations, and interactive animations for student use.

This lesson is part of a larger collection of resources for middle school chemistry, covering matter, changes of state, density, the periodic table and bonding, the water molecule and dissolving, and chemical change.

Please note that this resource requires Flash.

4. The Physical Setting

4D. The Structure of Matter
  • 6-8: 4D/M1a. All matter is made up of atoms, which are far too small to see directly through a microscope.
  • 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/M3cd. In solids, the atoms or molecules are closely locked in position and can only vibrate. In liquids, they have higher energy, are more loosely connected, and can slide past one another; some molecules may get enough energy to escape into a gas. In gases, the atoms or molecules have still more energy and are free of one another except during occasional collisions.
  • 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.

11. Common Themes

11B. Models
  • 6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.
  • 6-8: 11B/M6. A model can sometimes be used to get ideas about how the thing being modeled actually works, but there is no guarantee that these ideas are correct if they are based on the model alone.

12. Habits of Mind

12C. Manipulation and Observation
  • 6-8: 12C/M3. Make accurate measurements of length, volume, weight, elapsed time, rates, and temperature by using appropriate devices.
