Simple Machines - Levers

Exploring the effect of different fulcrum positions on ease of pushing down on the "teeter toter".  Closer to the load is the best!
This experiment was supposed to support the idea that a longer lever will ease the amount of perceived effort required.  What I didn't factor in, however, was the lack of skill in hammering!  The conclusion: all of the kids preferred to hold the hammer close to the head.
Playing around with third class levers.
