Skeletal System: Human Physiology in Space

In this web seminar for educators of students in grades 9-12 participants learned about the effects of microgravity on the physiology of astronauts and the countermeasures NASA uses to mitigate the effects of space travel and the return to Earth. Participating educators received an overview of two student activities related to this topic and got information about required materials. They also discovered strategies for guiding students in creating and testing their own models.


This web seminar is part of a series of electronic professional development experiences sponsored by the NASA Explorer Schools (NES) project. NASA Explorer Schools invests in science, technology, engineering, and mathematics educators to inspire and engage a whole generation of future scientists, engineers and technicians that NASA needs to continue our journey. NES gives educators of grades 4-12 free access to NASA's people, missions, research, and facilities. We take the work out of searching through thousands of materials on the NASA website and provide a comprehensive set of teaching materials for dozens of STEM concepts.
