Interactive courses · Chemistry first
Build atoms, read the periodic table, run real experiments in your kitchen — and find out how professional labs analyse a sample. An interactive course that goes from “what is an atom?” to “what’s in my tap water?”.


Add a proton and watch carbon turn into nitrogen. Remove an electron and see an ion appear. Interactive models sit right inside the lessons, so every concept is something you can poke at.

The periodic table is a map, not a list. Click any element to see its family, its shells and its valence electrons — and where you meet it in everyday life.

Split water with a 9 V battery, unmix the dyes in a marker, grow crystals, make a pH indicator from red cabbage. Every experiment lists exactly what you need, step by step, with clear safety notes — and explains what you just saw.

Predict how much gas a reaction should release, then weigh it on your kitchen scale. Calculators and quizzes help you check your thinking as you go.

Short questions throughout each lesson give instant feedback and explain the reasoning, whether you picked the right answer or not. Mark lessons complete and watch your progress through the course.

Every method in the course comes with the cheapest way to try it yourself, and what more becomes possible as you invest.
Red cabbage, baking soda, coffee filters, a 9 V battery. Real chemistry with what’s already in the cupboard.
pH strips, a 0.01 g scale, syringes, safety glasses. Your observations become measurements.
Glassware, a hotplate stirrer, a pH meter, a USB spectrometer. Titrations and colorimetry at home.
GC, HPLC, ICP and NMR — what they do, and how to get a sample analysed without buying one.
Part 1 · Foundations — how chemistry works, how samples are analysed, and what you can test at home.
Atoms, isotopes, electron shells and the periodic table.
How atoms stick together, and why salt dissolves but oil doesn’t.
Balancing equations, energy, rates and equilibrium.
pH, titration, rust, batteries and a first taste of organic chemistry.
Wet chemistry, chromatography, spectroscopy, mass spec and NMR.
What each instrument does, what goes in, what comes out — and what it costs.
Eight real experiments with things you already own.
What each step of investment unlocks, ending with a tap-water analysis.
Ten minutes from now you’ll know what everything is made of.
