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.

That's STEM addressing the lack of quality science education available to underserved students, particularly girls and children from under-resourced communities.Her own experiences growing up interested in STEM shaped the initiative. Having once worried about whether she belonged in the field, Liu wanted younger students to experience science as something they could actively participate in rather than simply study in textbooks.The organisation now works with 48 community partners, including libraries, YMCAs, Title I elementary schools and youth organisations.
