Our set lets pre-k through second-grade students set up a course of ramps, pendulums, hammers, switches 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 plastic pieces, the set is perfect for open-ended building—or kids can use the leveled challenge cards to create a variety of different courses from scratch! Set comes with 37 pieces, plus 4 balls, 6 challenge cards and a guide. The tracks measure 12\" in length.","brand":"Acme","offers":[{"title":"4 yrs. - 7 yrs. \/ Pre-K - 2nd gr.","offer_id":51921960992984,"sku":"US-1297-4-YRS-7-YRS-PRE-K-2ND-GR","price":52.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/1629\/6408\/files\/000708-create-a-chain-reaction-stem-kit-pre-k-gr-2-starter-set-01-f931d245.webp?v=1782709528","url":"https:\/\/lakeshoreus.com\/products\/create-a-chain-reaction-stem-kit-pre-k-gr-2-starter-set-pp565","provider":"Lakeshore outlet shop","version":"1.0","type":"link"}
