California teen turns free science workshops into a global 21-chapter nonprofit

A homemade catapult, a miniature wind turbine or a simple robotics experiment can do more than just introduce a child to science. It can spark the confidence to imagine a future in engineering, technology or environmental research. In Katelyn Liu's case, a young lady from California, the foundation for an ambitious endeavor was established by making these experiences available to children who might not have had the opportunity to participate otherwise.

Wow! What began in 2022 as a few free workshops held at a local library has grown into something much more than that. That's STEM, a youth-led nonprofit reaching thousands of students across continents.
