Instructional Ideas
- Begin class with a review of energy and its types — potential, kinetic, thermal, and chemical — and the Law of Conservation of Energy
- Introduce a new term, thermodynamics
Classroom Considerations
- Classroom must have a computer, Internet access, and a projection system
- Learners understand that compounds and molecules consist of bonds that can be broken
- This video is hosted on YouTube
Pros
- Video introduces the concept of change in heat being equal to heat plus work in a system
- Explains definitions of heat, work, and energy (in terms of chemistry) simply and well
Cons
- Introduces thermodynamics to learners from a physics perspective (through a trebuchet), then transfers this concept to chemistry; this may confuse some learners
- Video quickly covers energy, so you may need to spend more time on it to help pupils master the concept
