GCAA Physics teacher Alicia Dunn invited me to her 9th Grade Class to watch her students figure out how to slow down falling eggs. There is a serious reason to study deacceleration - - it's the principle on which air bags work. The supplies given to the students were extremely limited (see the instructions here and here). And then the eggs fell. Everyone seemed to be having a good time in the end, except for the eggs, who were smiling earlier on.
