In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases. Learners will then determine the CO2 contribution from automobiles and brainstorm ways they can reduce their carbon footprint. This lesson guide includes background information about the greenhouse effect and handouts for learners. [Activity is publicly available through a web crawler capture on Archive.org.]
