In this lesson, students examine how physical traits can be influenced by the environment. In the activity, Astronaut-in-Training, students analyze how a NASA astronaut’s traits changed during his “year in space.” Then they measure some of their physical traits (arm strength, height, and balance) and predict how their own traits might change after living in space.
