       There are several ways of incorporating physiology in the middle grades like my 4th grade classroom. There was a time we had the human body as part of the curriculum and there was a time we worked on our pulse rate etc. The interesting part of it is that students enjoy theses and will always learn as much as the activities allow them to, especially when it involves inquiry.

      The activity on reaction time will be a great one to teach the importance of paying attention or focussing. This will be very appropriate for safety lessons in social studies. As students practice, they will discover that they will get better. Just as Allan Bronstein mentioned, this will remind students that they should help spread the message that people should avoid using cell phones while driving.
