This is the building kit that applies science, technology, engineering, and math (STEM) principles to create and solve over 35 challenges. The set comes with 175 building pieces inspired by nucleotides, the basic structure that makes up DNA, as well as wheels, axles, rubber tires, 24 rubber bands, string, foam play pads, and a bouncing ball. An instruction booklet provides projects that challenge children to assemble a car, construct three-dimensional shapes, or build a contraption that pushes, swings, catches, or holds the included ball.
