HOW IT WORKS
Every lesson takes about five minutes.
See the idea, practice it, get help when you're stuck. Then come back tomorrow, because your streak and your rank are waiting.
1
See the big idea
A two-minute minilesson with visuals you can tap, plus a short video from a real chemistry teacher.
2
Practice in five questions
Multiple choice, typed answers and matching, with a hint that nudges instead of giving it away.
3
Ask Coach anything
A chemistry tutor that explains the why, shows the steps, and quizzes you on what you missed.
4
Clear the topic
Master every lesson in a topic, then beat its Boss Battle. Your progress bar fills as you go.
About five minutes. No account, nothing saved.
CLASS GAMES
The review game your class will ask for.
Put a live game on the projector. Students join on their phones, split into two teams, and keep their team's reactor stable by answering right. Every answer moves the needle.
Teams vote on a mascot name from their phones.
Ready in a minute. Pick a topic or lessons, put the code on the screen, and go.
Faster right answers score more. The team behind gets a comeback boost.
Quick 5 for the last ten minutes. Keep the reactor in the gold zone and everyone's XP doubles.
SAVE THE REACTOR
A week-long challenge for the whole class.
The class reactor drifts down a little every day. Students keep it stable by practicing on their own time, on any device. Put it on the projector in the morning and watch the class check the score.
Two teams, or the whole class against the reactor.
Class bonuses unlock when enough classmates play.
Stars for keeping it in the green all week.
FOR STUDENTS
Practice that pays off.
Get help the night before the test, earn your way up the ranks, and spend what you earn on real chemistry.
A tutor in your pocket
Ask Chem Coach why, ask how, or ask it to explain it simpler. It shows the steps instead of handing over answers, and can quiz you on what you missed.
10 free replies a week
Earn quarks. Unlock reactions.
Every 10 XP earns a quark. Spend them in your Lab Locker on flame-test colors, element tiles and reactions like elephant toothpaste and thermite. Spending never lowers your XP.
Climb ten ranks
From Intern to Nuclear Chemist. Your rank shows as electrons orbiting your picture, one more for every rank.
Boss Battles and Meltdown
Master a topic, then beat its Boss Battle. Season Meltdown gives you three lives and a fresh leaderboard every three weeks.
Videos from a real teacher
Lessons come with short videos from The Science Classroom, the chemistry channel with 100M+ views.
Pick up where you left off
Leave a quiz halfway and your answers wait for you. Weekly quests keep it fresh.
FOR TEACHERS
Assign in a few clicks. Know who needs you.
ChemCoach grades the work, tracks every retake, and tells you in plain English who needs help and what to reteach.
