Room 11's blog

Welcome to Room 11's blog
Earlier in the year, Room 11 learned all about Cars. We investigated the wheel and axle, effort, potential energy and friction. At the end of our topic we all made rubber band cars and balloon cars. Photos show some of the investigations we did.












Joe is helping us to investigate Simple Machines.
Did you know that the wheelbarrow is a very old simple machine? Only a small effort is needed to move a heavy load using a wheelbarrow. The wheel, axle, wedge and lever are all simple machines and important parts of the wheelbarrow. Can you find them all on the wheelbarrow in the picture?
