Instructional Ideas
- Extend the lesson by adding beeswax candles to the experiment
- Have the class determine which principles of green chemistry were involved in the lab
Classroom Considerations
- Lab groups should contain only two to three members
- Lead a brief discussion about where paraffin wax comes from to help illustrate the green components of the experiment
Pros
- Experiment offers a safer alternative to traditional enthalpy labs
- Thoughtful questions in the post-lab section ensure learners see the big picture of renewable resources versus non-renewable resources
Cons
- None
