Having taught physical science for two years at the high school level, my new assignment to teach seventh grade science was met with mixed emotions. I had heard that junior high students were very energetic (mostly for mischief) and were very limited in learning ability, due to a low reading level and a lack of mathematical skills. I know I had also wondered, like many of you in high school and college teaching, just why did high school age students have such poor concepts of motion, energy, light, sound and graph interpretation and use.
