Energy and Chemistry

Everything around you is related to chemistry and more specifically, the energy within a system. The video explores how energy, in its different forms, changes after conversion — given off as heat or absorbed as heat  in chemical reactions.

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
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
