The possibilities of discovery are multiplied when rich variables are at children's fingertips. The Inclined to Exploration Loose Parts STEM Kit is a laboratory of opportunity uniquely designed to inspire children to experiment and explore while being introduced to basic STEM principles and physics theories. Children 3 and up can investigate concepts of incline, friction and velocity while building using the included wooden pieces, corrugated tubes, plastic components and gear twist ties. As children engineer new paths and construct and deconstruct structures, they can send colorful marbles traveling through each new build. Parts can be stored and sorted using the included plastic compartmentalized tray.
