Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe. The lesson features a demonstration on how the incomplete combustion of fossil fuels releases particles into the air that can negatively affect human health, and how we can protect ourselves from breathing in these fumes. This standards-based lesson includes key vocabulary, extension ideas, and references for teachers. [Activity is publicly available through a web crawler capture on Archive.org.]
