Simple Machines (Station Approach)

kit #214

With this in-depth, three-activity kit, students measure the force required to lift objects using different simple machines. Each successive activity introduces new, more complex concepts that build upon and extend student understanding of force and motion. They calculate work input, work output, and mechanical advantage and are introduced to friction, efficiency, and the second law of thermodynamics.

This is a "station approach" kit that is designed for one small group of students. Although it can be used as a demonstration kit, we recommend purchasing enough kits so that all your students, working in small groups, can experience the lessons first-hand.

  • Energy is a property of many substances and is transferred in many ways.
  • Work done on an object is equal to the Force applied x Distance moved.
  • Machines can decrease the force required (mechanical advantage) but can not decrease the amount of work needed to move an object.
