Science is everywhere.
Now so is learning.
ScienceKid is a free supplementary STEM resource that takes learning beyond the classroom — real-world challenges rooted in science, math, engineering, and tech.
Learning beyond the textbook, in three steps
Pick a challenge or a track
Browse the challenge library or pick an adventure track — Space, Biology, Math Mysteries, and more. No schedule required.
Solve real-world STEM problems
Each challenge is rooted in actual science — not textbook drills. Finish in 5–15 minutes and walk away knowing something real.
Earn XP and unlock badges
Progress stacks up across subjects. Climb the leaderboard, build a streak, and unlock legendary badges along the way.
Explore the full STEM universe
Real-World Challenges, Every Day
Bite-sized STEM puzzles inspired by real science — finish one in 5–10 minutes and walk away understanding something about the world. Build a habit that outlasts any school year.
Master Skills, Earn Recognition
Unlock badges as you level up across subjects — from your first experiment to legendary all-subject champion. Progress here is yours to keep, independent of any school grade.
Follow Your Curiosity
Pick an adventure track — Space, Biology, Math Mysteries, and more — or just explore freely. Go deeper on what interests you, at your own pace, on your own schedule.
Adventure Tracks
Guided sequences through STEM topics — open for exploration or assigned by teachers.
Badge Hall of Fame
Master STEM challenges and unlock legendary rewards. Can you collect them all?
Bring the outside world into your classroom
ScienceKid is designed as a supplement, not a replacement. Students explore freely on their own — teachers add structure when they need it: assign tracks, set due dates, and track progress without walling off the rest of the site.
Full guide: How it worksVirtual classrooms
Create a class, share a join code, and approve students. Your roster, assignments, and progress views stay private to your class — not mixed with the whole site.
Assign & create tracks
Assign published adventure tracks or build your own custom paths. Keep them private for your classes or publish them for other teachers to discover and assign.
Dashboards built for teaching
See each student's XP, badges, recent attempts, and per-track completion — a progress grid at a glance, not a public leaderboard.
Open + focused challenges
The full challenge library stays open for curious learners. Classrooms let you add focus: required tracks, due dates, and completion tracking.
