Block and Tackle!

Mr Jacobsen set up his block and tackle pulley system especially for Room 11 on Friday afternoon so we could see how simple machines can help us move things.  After watching a video and checking out some pulleys in class, it was so much more fun trying to lift a crate of heavy bricks outside in the real world!  It took the effort and energy of three people to lift the load using a rope but everyone could lift the crate on their own with the help of the block and tackle.

Thank you so much, Mr J, for sharing this technology with us.
