Students discover how simple machines make work easier…as they build realistic models and perform hands-on experiments! Our lab includes high-quality, extra-durable beechwood components, plus 7 hands-on experiment cards that walk students through how to build and use a pulley, an inclined plane, a wheel and axle, and more. The cards even include information on back that explains each machine and how it’s used in the real world! Lab comes complete with 39 experiment pieces.
