This game box includes 6 DIY engineering projects. Each project conveys a different physics principle: mechanical linkage, friction, resilience and lever, robotic arm, inertia, and trotting horse lamp. It features lovely animal models to lead children into a wonderful animal world packed with fun and amazing engineering projects. These hands-on projects will make them feel engaged and accomplished while learning to solve problems on their own. These projects show us how to build animal models and learn how they move. During play, children make observations and assemble the model on their own, which helps improve their hands-on ability and spatial awareness. They also get to know about how simple machinery works. The game box comes with detailed and informative instructions to bring engineering and machinery closer to budding engineers.
