STEM Supplies Exclusive Product
ForceCourse Mini Pulley System Kits
Build and experiment with 3 types of pulleys to discover how they are different during force and motion activities. The smaller size of the pulley machine system allows students to set it on a table, desktop, or floor. They will use the set to construct fixed, movable, and compound pulleys and assess how much force is needed to pull each. Through the process, they learn which pulley system requires the most force, which requires the least force, how adding additional pulleys affects the load, and more!
Kit includes 1 frame (24"L x 24"W x 26-1/2"H; 4 lb 9 oz), 2 buckets, 12 beanbags (50 g ea), 2 ropes (6'L), 4 pulleys, 4 carabiners, and lesson direction that's adaptable for grades K-4 and 5-8. Patented. Kit accommodates 4 students. Set of 2 accommodates 8 students. Recommended for Elementary and up.

Next Generation Science Standards*:
-
3-PS2-1: Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
-
3-PS2-2: Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.
-
3-5-ETS1-1: Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
-
3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
-
3-5-ETS1-3: Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
-
MS-PS2-2: Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.
-
MS-PS3-3: Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.
-
MS-PS3-5: Construct, use, and present arguments to support the claim that when the motion energy of an object changes, energy is transferred to or from the object.
