Levers+Worksheet+Questions

A lever is a bar that turns about a point when pushed or pulled. The point is called a fulcrum. The pushing or pulling is called the effort. Levers are often used to lift heavy loads.


 * 1) Write four different examples of levers.
 * 2) Draw a picture of a lever labeling the effort, fulcrum and load.
 * 3) Build model B.1 from Green Card B and notice how easy it is to move the load and how far the load travels.
 * 4) Now build model B.2
 * 5) Which lever lifts a load easier, and why?
 * 6) Which lever lifts a load higher, and why?
 * 7) Build models B.3 through B.6. Draw a simple diagram of each model labeling the load, effort and fulcrum. Describe how each one works.
 * 8) If you want to lift a heavy load with you lever, would it be easier if the fulcrum was closer to the effort or closer to the load?
