For Teachers
Free projects across science, engineering, math, technology, and art — documented step by step, with real time estimates and material lists upfront.
Classroom-ready
Every project lists materials upfront, includes step-by-step instructions, and shows time estimates — so you can plan a lesson without surprises on the day.
Beginner through advanced
Filter by difficulty and age range to find the right challenge for your class. Projects span every level — from first-time experimenters to advanced analytical capstones.
Free, no strings
No subscription, no login, no per-student fee. Download, print, and use. STEMigoo is free because science education shouldn't depend on a school budget.
How It Works
No onboarding, no training required. Just find a project that fits your unit and go.
