In this Model-Eliciting Activity (MEA), students rank locations that NASA should search within our solar system for life. Students begin by reading about the origins of life on Earth and locations within our solar system with the potential for life. After students create a ranked list, they must report their findings to NASA in the form of a letter that also includes the procedure used in ranking their choices. A second request is sent from NASA to include distance from Earth as a factor in the ranking of locations and students must return a letter with their revised rankings and the new procedure used.
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.
