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.

If your child would like to participate in this years Eco-leader project please fill out this form and return it by Monday the 26th. Click HERE for form. This will involve two field trips to learn about environmental issues one of which students will attempt to help improve in an assignment they will present to the Mayor at the 2019 Mayors Expo. This is a great program and allows students to develop their leadership skills in the greater community whilst learning some important information about community projects, presentation skills and much more. A highly recommended experience for those willing to participate. This will come with time commitments during lunchtimes and potentially outside of school hours.
