STEMdelivered.org is a nonprofit creating games, books, and digital experiences that take science out of the lab and into real-world systems learners can explore.
"We help students understand ecology, economics, strategy, and survival through play — supporting classrooms, homeschoolers, and community learning spaces with tools grounded in how the world actually works."
Karen Blake is a licensed geologist and systems-focused STEM creator with a background in geology, computer science, and game development. She is the co-founder of STEMdelivered.org and the founder of Rhizome Books, Incorporated, where she develops mobile and tabletop games, puzzle books, children's stories, and digital learning tools.
Her work spans more than a decade of STEM enrichment projects, including the development of TANZA, Antelope Up, and multiple puzzle book series. She is an award-winning children's book author, poet, essayist, and photographer, with over a dozen professional publications — including contributions to peer-reviewed geological volumes and technical conference proceedings.
Dr. Debbie Bereki brings more than twenty years of classroom teaching, curriculum design, and educator training to STEMdelivered.org. Her doctoral work focused on science education reform, professional development with scientists, and classroom implementation of standards-based science instruction.
She has designed museum programs, coordinated teacher institutes, developed Earth science curricula, and led professional development across California. Her work centers on helping educators connect scientific expertise with practical classroom application.
STEMdelivered.org is a California nonprofit dedicated to making science, technology, engineering, and math genuinely engaging through game-based learning. We design experiences where learners don't just study systems — they navigate them.
Our materials are used in classrooms, homeschool settings, and after-school programs across the country. Everything we produce is built around real-world scenarios: economics, ecology, supply chains, and survival — wrapped in stories worth playing.
TANZA is our largest production to date, developed in creative partnership with Rhizome Studios — bringing the world of East African business strategy to life in vivid, culturally authentic detail.
