STEMsters was a great addition to our after school programs. The lessons were well done, straightforward, and used simple materials that we already had in the classroom. Watching the kids make connections was a great experience.

Curious about starting a chapter or exploring a partnership? Here's everything you need to know!
Start a chapter! Our national board walks new leaders through recruiting volunteers and scheduling your first workshop, step by step.
Our core curriculum is built for K-5 students, taught by trained high school and college volunteers.
Trained student volunteers do. Every chapter is student-led, mentored by our national board, so kids are learning from near-peers, not textbooks.
Reach out through your local chapter or contact us directly, and we'll match you with volunteers and a lesson plan.
Most workshops run about 45 to 60 minutes, fitting neatly into a single class period.
Log your hours anytime through our Volunteer Hours Tracker, tied directly to your chapter's activity.
