In this Model-Eliciting Activity (MEA), students are presented with an engineering problem where they must work as a team to analyze data to choose the best tree to plant in the serenity garden. The students will consider the cost, shade, height, leaf color, maintenance, and growth rate to choose the best tree that not only will benefit the environment but also this nature preserve. The students will work in teams to decide on a process of how to rank these trees from "best to worst" as well as explain how they arrived at their solution using a letter format.

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
