Have you ever wondered how much energy there is in the foods you eat? What if I told you that a single Hershey Kisses has enough energy to lift a full-size SUV 6ft off the ground? Would you believe me? Well...the students didn't at first either. However, they quickly learned how to convert energy between different units using dimensional analysis and see just how much potential energy there is in food. Crazy!!
Students had to bring in a snack to eat during review but there was a twist - they had to figure out how much energy they consumed in Joules (a unit of energy) and figure out how many flights of stairs they would have to walk to "burn it off". While, there are more variables to burning off Calories (Joules) than just that, the concept is the same. Most students were surprised just how much work their body would have to do in order to burn off the Calories they consumed. Check out a few pictures from 4th block.
