Year 8 · Spring First Half
Chemistry
4 lessons from 2 units.
Unit C5 · lessons 4 to 5 of 5
Most of the reactions you will ever meet are one of a small number of kinds. This unit is about four of them — what each one does, what it needs, and how to tell which one you are looking at when nobody says.
Unit C6 · lessons 1 to 2 of 7
An acid and an alkali are not things you can see, weigh or smell. They are things a substance does — to a dye, to a metal, to each other — and this unit is about reading those behaviours, predicting them, and using them on purpose.

- 05Which reaction is this?ClassifyFour types, and nobody labels them for you. What do you look at first — and what do you do with a reaction that fits none of them?Open this lesson
- 01Acids and alkalisClassifyTwo clear, colourless liquids. One is an acid and the other an alkali, and both can burn your skin — and nothing you can see tells you which is which.Open this lesson
- 02The pH scale and indicatorsModelA dye squeezed out of a boiled cabbage can tell you something about a liquid that no amount of looking at it will. What is it actually reading?Open this lesson
