Create-A-Chain Reaction STEM Kit - Pre K-Gr. 2 - Master Set

Kids set off a chain reaction of fun! Our master set lets pre-k through second-grade students set up a course of ramps, pendulums, hammers and more…then drop a ball onto the tracks and go for the goal box! After each test run, kids will fine-tune the placement, distance and angle of each piece—getting firsthand practice with STEM concepts such as gravity, force and momentum! Packed with super-durable pieces, this set is perfect for open-ended building—or kids can use the leveled challenge cards to create a variety of different courses from scratch! Our master set comes with 67 durable plastic pieces—including tracks, pendulums, hammers, switches, a goal box and more—plus 6 balls, 10 challenge cards and a guide. The tracks are 12" long.
