Science on a Budget: Measure Horsepower!

 My husband, Rob, teaches Physics.  I help him with lab ideas.  When I teach Physical Science the kids do this Horsepower Lab, which outlines the steps to take for calculations well. The lab is free and helps kids understand key energy concepts.  It’s a lot of fun watching kids thunder up and down stairs.  You can make the lab more inquiry based by comparing a student’s horsepower on concrete, wood, laminate, and carpeted steps.  Do extra trials; there is considerable variability inherent to human experiments.    Rob has the kids report the data in a spreadsheet and write a formal lab report.  Have a blast!
