Simple+Machines

media type="custom" key="4209031" Check out all the simple machines used in this video. The sailor (Matt, my son and Jessica's twin brother) is acting as a lever, there are lots of pulleys on this particular boat (laser) and others levers as well. The front of the boat also acts as a wedge cutting through the water. Matt will be visiting the class with his laser in the university break and showing the class all the simple machines which make up this complex machine and hopefully explaining the principles behind each one. We will add pictures and a slideshow after his visit to show what we have learned.
