Whatever Pulls Your Sled by Jeanine Wolf
Students will test determine if the surface of an object will effect how much force it takes to pull that object. They will then determine the most efficient way to attach the string to the object to reduce the necessary force and finally they will adjust the take off and pull velocities to determine if they affect the force of the object. This lesson was designed and aligned to standards for 7 – 8th grade students, but can be adapted and used at any grade level.
