Product Description
Using levers and 3 types of pulleys, students will complete this investigation in which they are to discover the relationship between the effort force and distance on a simple machine. Students will need the following materials for each part of the lab. I used the materials given to me in a simple machines kit. Students fill in 2 data tables for the lever lab: Moving a weight in relationship to the fulcrum & moving the force in relationship to the fulcrum. Students will then fill in 1 data table for the pulleys. Students then graph data using graph paper.

2. On opposite side of lever, place spring scale 5 cm away from fulcrum.
3. Measure amount of force needed to balance lever five times (n).
4. Record force in data table.
5. Move scale to 10, 15, 20, 25 cm and record force (n).
