Why Avanza STEM Exists
Avanza STEM began as my Eagle Scout project, where I organized four STEM workshops at local libraries. I wanted to give kids a chance to explore engineering for themselves, so I developed activities where they could design, build, and test bridges using inexpensive materials.
After completing my Eagle project, I've decided to keep going, and since then, Avanza STEM has grown to 30+ workshops, reaching over 300 students. I (with some help from my friend) built this website with free projects in engineering, coding, and other STEM subjects so students can continue learning outside our workshops. Feel free to look around!
More recently, we've started sharing our workshop materials with libraries across Latin America. By providing Spanish-language presentations and step-by-step guides, we're making it easier for librarians and volunteers to bring these activities to their own communities.
The goal has stayed the same since those first four workshops: give more kids the chance to discover an interest in STEM, regardless of the resources available to them.

What people are saying
Partner libraries and community groups describe the Maker Mindset Series in their own posts, to their own communities.
The Maker Mindset Series, hosted by Liam Salcedo & Tommy Qi, high school students from Seton Hall Prep, brought students together at The Library of the Chathams for three fun, hands-on STEM workshops. … More than just learning about engineering, coding, and AI, the program gave students the ability to be curious, creative, & collaborative in a welcoming community space.
A big thank you to Liam Salcedo and Tommy Qi, two rising seniors at Seton Hall Prep, for bringing “The Maker Mindset” STEM series to the Roseland Library! During this three-part series, participants ages 8 and up learned how to build and test suspension bridges, Python coding basics, and how artificial intelligence works through fun and interactive approaches.
YA Creates: Maker Mindset Series where students explore engineering, coding and artificial intelligence through hands-on interactive activities with Liam, our volunteer.
For his Eagle Community Service Project, Liam, 17, planned and ran a series of Saturday STEM workshops for kids at the Clifton Public Library last December and January. Liam's goal was to give local children access to engaging STEM opportunities they might not otherwise have access to. … He used it as a springboard to launch Avanza STEM, a youth-led, free STEM resource offering workshops and more, focused on reaching Hispanic and underrepresented students.
