When it comes to finding an innovative, engaging, and great-quality STEM toy, KiwiCo offers STEM activity crates or individual STEM toys for every age.
The STEM-specific crates will engage your child as they learn chemistry with fun experiments, or figure out mechanical principles by building a mechanical claw or a machine that can build a domino run.
The instructions are easy to follow, with key teaching moments incorporated in the entire process: the child will be able to “put it all together” and apply their learned new knowledge and skills in their everyday life, leading to more “Eureka” moments.
For example, the Domino Machine combines mechanical and electrical engineering, physics, and critical thinking to help your budding engineer explore and apply STEM principles: your child will build a machine that picks up and spaces dominoes at a specific distance to create a domino effect. Your child will learn how to follow directions, and how to assemble gears, parts, and motorized components.
