Instructional Ideas
- Set students up for success with the Ideal Gas Law by introducing amount of substance using the interactive
- Pass out graph paper and ask pupils to create a graph of the number of particles versus the volume of the gas
Classroom Considerations
- Make sure learners are clear about the pressure within the system; they should also understand volume units
Pros
- The resource is simple and responsive
- Users can measure the volume with six different amounts of molecules
Cons
- None
