Introduce kids to angles, trajectories, and other early physics fundamentals with the Crashapult STEM Challenge. This hands-on activity set challenges kids to build and complete high-flying obstacle courses designed around core STEM concepts. After setting up their catapults, kids send the launch balls flying off walls, over obstacles, and toward the included hoop target, funnel, or goal cup. Along the way, they use trial-and-error, engineering, and critical thinking skills to make the adjustments needed to complete the challenges. Each set comes with a full-colour booklet filled with challenges that increase in difficulty. Size: 25.4 x 25.7 x 11.7 cm. Ages 6+.
