What everything is made of and how substances change. This course covers the full Cambridge IGCSE Chemistry syllabus, Core and Extended, from particles and bonding through the mole, energy, rates, acids, metals, the environment and organic chemistry to practical skills and chemical tests.
Lesson 1 is free to try. The other 88 lessons in Chemistry and its exam practice are for schools on RudimentaryLabs.
Why solids, liquids and gases behave so differently, explained by tiny particles that never stop moving.
What is inside an atom, and how atoms hold on to each other to make every material around you.
The bookkeeping of chemistry, from writing balanced equations to counting atoms by weighing them.
How electricity can split compounds apart, coat objects in metal, and be made from hydrogen and oxygen.
Why some reactions warm their surroundings and others cool them, and how to calculate the energy involved.
How fast reactions go, how some run both ways, and how electrons move in oxidation and reduction.
How acids and bases cancel each other out, how to classify oxides, and how to make pure salts.
How the Periodic Table works as a map that lets you predict how an element will behave.
Why metals are so useful, how their reactivity compares, how to stop them rusting and how we get them from rocks.
The chemistry of clean water, fertilisers, polluted air and a warming climate.
The families of carbon compounds behind fuels, alcohols, vinegar and plastics.
The practical skills chemists use to measure, separate, purify and identify substances.
