Students can construct, examine and explain simple machines to develop a deeper understanding of how they make work easier. Contains enough pieces to build a lever, pulley, inclined plane, wheel and axle, and wedge—all at the same time. A 5-in-1 value! Modify machines with 4 included weights (two 5 g and two 10 g) and 8 included rubber bands to explore effort, force, load, motion and distance. Labeled pieces assemble easily and separate to store. Includes Activity Guide. Largest models (pulley and inclined plane) measure 14cm L x 14cm W x 30cm H.
