Levers and Pendulums
People since ancient times used scales based on levers to weigh objects. We calibrated scales made from paint stirring sticks, then used our results to discover the location of a three objects hidden in sixteen film canisters based on their weight.
The predictable periodic motion of pendulums was the basis of accurate time keeping until the middle of the 20th century. We explored the variables that determine how a pendulum swings. Just for fun we added a Hooke’s Law station.
