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 students
  • 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
