Eight lessons following your textbook section by section, each with something you can drag, mix, heat or break. Then a one-page map of the whole chapter and twenty interactive questions.
The lessons follow the four questions your textbook chapter is built around. Work through them in order the first time — each one leans on the one before.
This is scoped for G3, so everything here is examinable — including the acid-with-metals and acid-with-carbonates reactions and the electrolysis work, which the textbook marks as optional only for G2. Treat all of it as core.
A few boxes are marked Extension. Those genuinely go beyond the syllabus — balanced chemical equations, redox, atom economy. Read them if you want to see where the topic leads next, but they will not be examined.
Physical vs chemical, the two groups of chemical change, reactants and products.
Start → Lesson 2Writing word equations, counting atoms, and why mass is always conserved.
Start →Three of the four types — with a live thermal decomposition and the rusting investigation.
Start → Lesson 4The pH scale, litmus, Universal Indicator and natural indicators — ten substances to test.
Start → Lesson 5Neutralisation, acids with metals and carbonates, naming the salt, and the four gas tests.
Start →The five triggers: mixing, heating, light, oxygen and an electric current.
Start → Lesson 7Splitting water and salt, electroplating an object, and photosynthesis as respiration reversed.
Start →Cooking, respiration, decay, preventing rust, air pollutants, and ocean acidification.
Start → RevisionThe concept map from the end of your chapter, plus every word equation and gas test in one place.
Open → PracticeMultiple choice, equation building, sorting and structured questions — marked as you go.
Practice → Challenging · Lvl 2Twenty harder questions with the options set deliberately close together — only correct reasoning separates them.
