The Scientific Pulleys play panel features 2 identical weights (the load) which are connected to a stainless steel wire rope via two different pulley types. One is a straight up and over single pulley which offers no mechanical advantage and the other features a second pulley wheel which does. The idea is for the children to experiment with the two different systems and record the differences between the two systems. There is an information panel which gives the children some experiments to think about and a Results and Observations dry wipe board insert to record the data. All the mechanics are safely located behind shatter-proof polycarbonate windows and the pull cables are short to prevent any miss-use.
