Instructional Ideas
- Tell pupils to add atoms to the balloon until they observe the dotted line of the barrier positioned closer to the inside of the balloon than the outside of the balloon. What would happen if they added too many atoms?
- Change the scenario and remove a large number of atoms from the balloon. What would the balloon look like?
Classroom Considerations
- Conduct a review of velocity with the class so they understand the concept as it relates to gas pressure
Pros
- The resource changes quickly as users add and remove atoms
- Arrows showing the velocity of each atom can help incorporate that concept into the lesson, or you can remove them entirely
Cons
- None
