Document Content and Description Below

Student Exploration: Levers Vocabulary: effort, first-class lever, fulcrum, lever, load, mechanical advantage, second-class lever, third-class lever Prior Knowledge Questions (Do these BEFORE usin... g the Gizmo.) 1. A lever is a rigid plank or bar that pivots on a fulcrum. Look at the lever in the picture. Where would you push on the lever to lift the rock? On the plank. 2. Where are some places that you see levers in everyday life? Seesaw, scissors, balances, crowbars, and hammers. Gizmo Warm-up In the Levers Gizmo, the strongman tries to lift animals by pushing down or pulling up on the lever. The force of his push or pull is the effort The weight of the animal is the load. Both forces are measured in newtons.  You can move the fulcrum to the left or right by dragging it.  You can drag animals to any spot on the lever.  You can move the strongman by dragging him.  You can change the strongman’s Effort with the slider. 1. Drag the pig to the lever. Try to arrange the lever so that the strongman can lift the pig. What did you do so that he could lift it? The pig is 1.5 meters from the fulcrum, and the strongman must be at least 4 meters from the fulcrum. 2. Did the strongman pull up or push down to lift the pig?
