Lesson Plan: Clean Air Chemistry
In this lesson, students will learn about air pollution and some steps toward mitigating it. First, they will burn a candle and measure its mass and the concentration of CO2 over time. Students will discuss which data set they have more confidence in and why and then use stoichiometry to predict outcomes. Next, students explore incomplete combustion in a model-based worksheet that shows how a lack of O2 in the burning of fuels can produce air pollution. Students work together to interpret the models, define terms, and draw conclusions. Lastly, students work in groups using Lego models to illustrate how a catalytic converter works. They race “Nature” against catalysts “Palladium,” “Platinum,” and “Rhodium” to see what breaks down air pollution molecules fastest.
