Pulleys and Bridges.

We are having some fun in grade 4 and 5 today. We are doing some experiments in class to reinforce what we have learned about pulleys and bridges. The grade 4 students are doing their experiments to see the difference between fixed pulleys and mobile pulleys. The grade 5 students are putting their engineering abilities to work to see who can build the strongest bridge. It was great being able to walk around the classrooms and hear them using their scientific vocabulary to explain what they were experiencing.
