All together now! Physical science pupils observe the effects of temperature and amount of substance on pressure and volume of a gas. The interactive resource guides learners through the Combined Gas Law, where they observe changing conditions within a system and draw conclusions about the pressure-temperature-volume relationship.

Instructional Ideas

• Use the activity to explore the kinetic energy of the particles as temperature increases, as well as the effects on pressure as particle collisions increase
• Make the interactive a gas laws inquiry by having the class follow the instructions, then answer the guiding questions as they work

Classroom Considerations

• Lead a brief review of velocity and its applications within the resource

Pros

• Velocity vectors give users an accurate depiction of increases and decreases in velocity as conditions change
• Temperature, pressure, and volume are measured with simple gauges on both sides of the piston wall throughout the interactive

Cons

• None
