Pulleys

We are currently exploring forces in science.  Students have been learning about the types of forces and the concept of loads.  We have been doing lots of hands on investigating including using large pulleys to explain the concept of mechanical advantage.  Local scientist, John Wills joined us for this activity.  Last week we headed down to the marina to check out how pulleys are being used in multiple configurations on sailboats.  
We also have been learning what makes structures strong and stable.
