In this Model Eliciting Activity (MEA), students are asked to help their client select the "best" asteroid to explore given several different factors. Students collaborate in small groups to develop a procedure to rate the asteroids. They are then asked to write a letter back to the client, defending and explaining the procedure they developed. This MEA has been written based on NASA's current mission to explore an asteroid to prepare for the mission to Mars.

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
