The 220 Piece Design And Build STEM Challenge

This is the building kit that applies science, technology, engineering, and math (STEM) principles to create and solve over 35 challenges.

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.
