Once you’ve taught the vocabulary of work input and work output, use this hand on lab activity to introduce simple machines. Students build various configurations of 1st, 2nd, and 3rd class levers and measure effort force, effort distance, resistance force and resistance distance. They use that information to calculate mechanical advantage and determine how each class of lever makes work easier.
This resource includes 4 pages of directions, 3 page data table, and 3 pages of analysis questions as well as a 1 page explanation for teachers.
This hands on activity is provided as a PDF and will take 3-4 class periods to complete.
Suitable for middle/high school students who have already learned about work.
