Our kid-pleasing kits challenge stu- dents to build a variety of chain reaction courses—complete with switches, seesaws, hammers and more. Children simply grab a challenge card…build each of the pictured components with help from the “how-to” book…then set up their course. With the drop of a ball onto the tracks, kids will find out whether their course works—fine-tuning the distance and angle of the pieces until the ball reaches the goal box. Perfect for building 21st-century skills like perseverance and STEM problem solving, the kits even let kids create their very own chain reaction courses—for unlimited building possibilities!
