This learning cycle features five videotaped experiments, organized sequentially for introducing pressure and gases. It explores the relationship between pressure and volume, and volume vs. temperature of a gas. Each video includes learning goal, prior knowledge required, and post-activity questions. The instructional method is based on cognitive apprenticeship, in which students focus on scientific process by observing, finding patterns, modeling, predicting, testing, and revising. The materials were designed to mirror the activities of scientists when they construct and apply knowledge.

4. The Physical Setting
4D. The Structure of Matter
6-8: 4D/M8. Most substances can exist as a solid, liquid, or gas depending on temperature.
4E. Energy Transformations
6-8: 4E/M3. Thermal energy is transferred through a material by the collisions of atoms within the material. Over time, the thermal energy tends to spread out through a material and from one material to another if they are in contact. Thermal energy can also be transferred by means of currents in air, water, or other fluids. In addition, some thermal energy in all materials is transformed into light energy and radiated into the environment by electromagnetic waves; that light energy can be transformed back into thermal energy when the electromagnetic waves strike another material. As a result, a material tends to cool down unless some other form of energy is converted to thermal energy in the material.
