Experiment Tracks
An experiment track is an ordered set of experiments that develops a single big idea from first principles to richer applications. Work through a track top to bottom, or dip in wherever your curiosity (and your chemical shelf) takes you. Every experiment still lives in the full experiment library — tracks just give you a path.
Acid–Base Track
From fizzing volcanoes to the full pH landscape: what acids and bases are, how they neutralize, and how we measure them — including indicators you extract from red cabbage and other plant pigments.
Redox Track
Electron transfer, the engine behind colour changes, metal plating, dye vats, and photographic images. The site’s largest track.
Crystals & Solutions Track
Solubility, supersaturation, and the growth of ordered solids — from overnight gardens to phase-change heat storage and piezoelectric crystals.
Electrochemistry Track
Chemistry turned into electricity and back: build battery cells, split water, electroplate copper, anodize titanium in colour, and store charge in a home-made supercapacitor.
Cleaning & Surfactants Track
The real chemistry of getting things clean: how soap and surfactants lift grease into micelles, making soap from oil and lye, and matching acids, alkalis, and enzymes to the stain in front of you.
Food Chemistry Track
Edible experiments you can eat: proteins denaturing into cheese and meringue, emulsions and gels, the browning of caramel and toast, fermentation, and the freezing-point trick behind instant ice cream.
