We are going to be starting a new science unit on Pulleys and Gears. You will be broadening your understanding of structures by looking at 2 special kinds of whelels: Pulleys and Gears. Pulleys are used singly or in combination to move an object from one place to another. Gears can be used in combination to change speed and direction of movements. To help get you started on the unit I have provided a game for you to play about Pulleys for you to take a look at as well as a video on gears from the series "How Stuff Works". Mad Science is going to be coming to our classroom next week to give a presentaion on Pulleys and Gears and help us create our very own gear. We are going to have a lot of fun with this unit!
