BirdBrain Catalyst is a screen-free STEM kit for primary and early high school students, focusing on hands-on engineering with real motors, wood, and hardware to build imaginative moving creations, emphasizing problem-solving through challenges rather than step-by-step instructions, making abstract concepts tangible and fostering creativity in engineering and robotics. It's designed to spark innovation and teach principles of circuits, forces, and design using reusable parts and inspirational challenge cards, not just coding.
