This Model Eliciting Activity (MEA) is written at a 4th grade level. In this open-ended problem, students are presented with a variety of natural resources found in Florida, a description of the resources, and the advantages/disadvantages of each. Students must consider which resources are both environmentally friendly and beneficial to our society. Students will describe their procedures for reasoning, and defend their decisions by providing proper validation.

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.
