Dangerous chemistry,
made harmless.
Real chemistry,
made unforgettable.
A complete laboratory in your browser: a bench that keeps honest books on temperature, pH, and mass; fifty reactions worth discovering; technique graded A through C; and a thirty-lesson illustrated textbook from first fizz to nuclear chemistry. Every explosion is free.
Everything here actually reacts.
Pour any of forty-three reagents into a beaker that answers honestly. Light the burner and watch the thermometer agree. Trap the gas above the reaction and test it with a lit splint. Filter the precipitate, evaporate the filtrate, weigh what's left. The bench doesn't play an animation at you — it runs the chemistry and waits for you to notice.
Around the bench sits a whole building: a skills wing that grades your hands, a machine shop of working instruments, a college floor with kinetics and buffers and NMR, and a textbook wired into all of it.
Thirteen rooms, one building.
Four stubborn principles.
A desk that does the paperwork.
Hand-in codes that grade themselves with no server. A syllabus mapper with OpenStax chapter presets. An unknowns engine that deals every student a different sample from one pack code — and prints you the answer key. Pre-lab gates with verifiable vouchers. A ready-to-run efficacy pilot kit, pre/post instrument included.
Guided Experiments
Real lab technique, step by step. Follow the protocol exactly for an A — every stray chemical you add costs you. Grades and XP are recorded once.
Skills Lab
Measurement, energy, rates, and detective work — the labs that teach you to DO science, not just watch it. Every station ends with a real lab report: claim, evidence, reasoning.
Lessons
Short, focused units. Read the pages, pass the quiz, earn your XP — then go prove it on the bench.
The Balancer
Atoms are never created or destroyed — make the books balance. Adjust the coefficients until every element counts the same on both sides, in lowest terms.
The Elements
All 118, from hydrogen to oganesson. Select any tile for its record.
No element selected.
Molecules
Formulas are recipes; structures are the finished dish. Select a molecule to see how its atoms actually connect.
No molecule selected.
Formation Lab
Not everything happens in a beaker. Apply pressure, heat, current, or a star's gravity and watch raw matter reorganize into diamond, glass, steel — even the elements themselves. Make it, then prove you understand why.
College Lab
Three real instruments, real math. Titrate an unknown to a pH curve, build a calibration line the way analytical chemists do, and wire electrochemical cells from the reactivity series.
Problem Sets
Randomized numbers on every problem — your values are yours alone. Answer within tolerance, and every miss comes with the full worked solution.
The Model Shop
Six working models of what no microscope can show: squeeze a gas, boil a heating curve flat, stress an equilibrium, snap atoms into molecules, seat electrons one arrow at a time, and watch pure randomness keep perfect time. Every station signs off its challenges for XP.
Discovery Journal
Every named reaction you have produced on the bench, logged for posterity. There are ? to find.
Every discovery is a specimen on the shelf, filled with what you actually made. Click a vial to jump to its entry; the empty ones are still out there.
Teacher's Desk
No accounts, no servers, nothing leaves the room: students hand in a progress code, and this desk turns codes into a class roster. All data stays in this browser.
Compose a lesson with reading sections and a quiz, then hand students a lesson code — it appears in their Lessons view, quiz, XP and all. Lessons live in this browser; codes carry them anywhere.
Bundle lessons, protocols, and skills stations into one assignment. Students paste the code and get a live checklist on their home screen.
Assemble a test from the standards-tagged question bank. Students paste the code; questions run in sequence with no feedback until the end; the score rides home in their hand-in code.
A day-by-day plan for any unit: readings, quizzes, bench work, and the standards each day satisfies.
A themed bundle for each stretch of the school year — discoveries to hunt, lessons, and stations, pre-assembled. Copy the code, send it to the class, done.
One pack code, three hundred different unknowns: each student's concentration is derived from the pack's seed and their name, so copying a neighbor fails by construction. Their result auto-grades and rides home in the hand-in code; your answer key regenerates on demand.
Professors think in chapters, not feature lists. Pick a chapter and get a curated playlist — lessons, stations, and instruments — as one assignment code, ready for your LMS page.
Students who finish a Pre-Lab-gated assignment mint a Green Light voucher tied to their name. Verify any voucher here in seconds — no server, no lookup table.
A matched pre/post assessment with a gains analyzer. Give the pre-test before you teach, the post-test after, collect hand-in codes, and read the class's normalized learning gain — the number pilot schools and grant applications ask for.
