How a lever changes force or distance depends on the location of the input and output forces relative to the fulcrum. The input force is the force applied by the user to the lever. The output force is the force applied by the lever to the object. Based on the location of input and output forces, there are three basic types of levers, called first-class, second-class, and third-class levers.

Welcome back Everyone! I hope everyone had a great break and had time off to spend together. We are refreshed and back in full swing again; learning about light and shadow, multiplication and revising our regions of Alberta knowledge. The students and I have been on a roll in gym loving the Alien inline skating unit with some great skills on display and students skating rings around their (beginner skater) teacher. To extend the knowledge of your child get them to explore and then explain the following resources we have been exploring in class. GLENBOW BLACKFOOT Alberta regions Light and shadow
