In this Model Eliciting Activity (MEA), students must assist an archaeological research team to determine which material ancient archers likely used to string their bows. Students must design an experiment to test various materials for power, precision, and durability. After the data is collected, they must develop a system to determine which material would have been most desirable for the ancient archers.

This MEA is a multifaceted lesson designed to address both the processes of discovery through scientific investigation and problem-solving through engineering. The full-scale MEA involves the development of a complete experiment and a proper lab report and then an application of the collected data to address the problem-solving requirement of the MEA.

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
