Like other machines, a lever makes work easier by changing the force applied to the machine or the distance over which the force is applied. Classes of Levers Other levers change force or distance in different ways than a hammer removing a nail. 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.

Hello everyone, Sorry for the absence recently, I had to go home to assist with family matters in Australia. The students were left in very good hand with Mrs Samphire.

We have been researching and learning about the many regions of Alberta and the different characteristics they each have allowing student to write an I survived story based on one of these regions. We are continuing to learn about simple machines in science and are beginning to make plans for our upcoming BMO entrepreneurial challenge where we will be using our scientific learning to create arcade games with recycled materials incorporating multiple simple machines. We have began using equipment in gymnastics working on balance, locomotion and controlled landings. I also heard that the students really liked the Auskick program that...
