Physical Science bustled around investigating free-fall acceleration and all groups completed their work. What I gathered from circulating around was that data collection went well and groups realized that (1) the accepted value for acceleration due to gravity is not a "magic number," but can be measured in the lab and (2)acceleration due to gravity is constant acceleration - it does not change with time or speed of descent. This allows its use in kinematics equations with confidence. BTW: here's what some of you looked like at the end of the period:
