Instructional Ideas
- Include as a warm-up activity in a physics class when discussing the laws of thermodynamics
- Have learners study or build real-life perpetual motion machines and see if they run into the same problems described in the video
Classroom Considerations
- Best used with some prior knowledge of energy sources
Pros
- Takes a complex subject and explains it for learners of all levels
- Employs examples of ways that successful perpetual motion could change modern energy consumption
Cons
- None
