In Good Stress: Building Better Muscles and Bones, students will learn about the importance of building and maintaining better muscles and bones. They will learn that all stresses in life are not "bad." In fact, the body needs "good"stresses, like exercise, to be healthy. Students will see how scientists and researchers collect and analyze physiological data to understand how muscle and bones are constantly changing, especially in a microgravity environment. By conducting inquiry-based and web activities, students will make connections between NASA research and the mathematics,science,and technology they learn in their classrooms.
