In this Model-Eliciting Activity (MEA), students must choose which type of automotive power plant is the best choice for a car company to use in its upcoming eco-friendly model. The students must make this decision based on characteristics of each power plant, such as efficiency, production cost, and production energy. Students must decide what they feel makes the car most “ecological.” They may choose a very low-polluting car that is very difficult and costly to produce, or one that has more emissions, but uses very limited resources to develop. This lesson could be used to either as an introduction or a follow-up to a lesson about ecology, energy use and conservation, or human environmental impacts.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator. To learn more about MEAs visit: https://www.cpalms.org/cpalms/mea.aspx
