Blending engineering with physics, students build a marble run, then observe projectile motion and centripetal force as marbles glide through it. Kits include laser-cut birch wood parts, metal axles, marbles, and assembly instructions in graphic novel format to communicate meaningful STEM concepts in a unique way. The thrilling Dragon Coaster features steep drops and hairpin turns, while the cool Skate Park boasts a stair descent, rail slide, and jump. Motor Kit automates a marble run, enhancing learning with lessons in circuitry, gear trains, and torque (requires 2 AA batteries). Models take 3-5 hours to build and measure 8”H when complete. Models require glue, screwdriver, and pliers (not included). Recommended for Middle School and up. See full contents lists below.
