About This Lesson
Refrigeration and cooling make food safer, people more comfortable, and protect us in heat waves. The chemicals used to power cooling can be extremely powerful greenhouse gases, adding to climate change. Students investigate the Montreal Protocol, CFC and HCFC replacement, summer heat patterns, and the physics of infrared energy. Then, they investigate two real-world questions in their local community.
