In the Basketball Blaster Laboratory Kit for physical science and physics, perform a double-ball drop and experiment with different combinations to create the best “basketball blaster.” Blast off to new heights!
Blast off to new heights! Place a marble on top of a basketball, drop them together, and the marble will shoot up to the ceiling—a real eye-opener! In this unique hands-on laboratory activity, students perform this double-ball drop and experiment with different ball combinations to determine which arrangement creates the best “basketball blaster.” Students use the scientific method to explore the laws of conservation of momentum and energy and identify key variables, such as compression and mass, that affect the rebound height. The theoretical height the top ball can reach is nine times the original drop height! How high will your students’ go?
Marbles, mini-basketballs, Ping Pong balls, rubber balls, student worksheets, background information and complete instructions are included. All materials are reusable! Meter sticks, support stands and buret clamps are required for each lab group and available separately.

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-PS3-2. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object. HS-PS2-1. Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration. HS-PS2-2. Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system. HS-PS3-2. Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motion of particles (objects) and energy associated with the relative position of particles (objects).
