The access gap
We mail the lab straight to the kid
Whether a kid gets to try engineering usually depends on their school having a lab, a robotics club, or a budget. Most don't.
Circuit Sprout closes that gap the direct way: free, grade-tailored kits packed with real STEM materials — electronics, chemistry, robotics, engineering, and more — so kids can build at home.
What's in every box
Real tools, not toys
Every kit is packed with real STEM materials for the category you choose — electronics, chemistry, robotics, engineering, and more — matched to the student's grade.
- Hands-on STEM materials matched to the category you choose
- Projects sized for elementary, middle, or high school
- Real tools and supplies kids can build and experiment with
- Everything packed and shipped free to approved families
