    Have you seen the old version of the move Total Recall? There is an interesting scene where Arnold Schwarzenegger is exposed to the Martian atmosphere. Watch the video to see what happens.

    Why does this happen? I am glad you asked! It is all about PRESSURE. Arnold's head hadmore pressure than the Martian atmosphere.

    In this session, we will explore earth's energy and the atmosphere. Stay tuned for how that relates to pressure!
