In this Model-Eliciting Activity (MEA), students will work in teams to help Greens R Us, a fruit and vegetables business, decide which type of shopping bag to give their customers. Students will consider factors such as renewable and nonrenewable resources, environmental impact, and sustainability. This MEA allows students to use high-level problem solving skills in a real-world application involving Earth's natural resources.

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
