STEM Lessons - Model Eliciting Activity
This MEA is based on a 6th grade life science standard. Using a doctor's report, students will create a checklist and system of identifying organs and body systems affected by the patients symptoms.
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. Click here to learn more about MEAs and how they can transform your classroom.
Students will learn about the musculoskeletal system with a focus on the skeletal system. In addition, students will be able to incorporate the importance of bone density and ways of improving it by helping to select the best weight bearing cardio machine for their fitness center.

Students will learn how exercise is helping astronauts decrease bone and muscle loss during extended stays in micro-gravity. They will be asked to design an exercise program that utilizes both aerobic and muscle-building workouts while using the 3 exercise machines currently in use on the International Space Station. Then, the students will learn that current research suggests that more intense, short bursts of exercise may be more effective at decreasing bone and muscle loss, and they will be asked to redesign their workout prescription accordingly.
