Differentiated for Foundation, Higher and mixed‑ability classes, with sentence starters, worked examples, dilution tables, and higher‑tier challenge tasks clearly labelled.

Perfect for EAL learners and low‑attaining students, with A4‑ready formatting, colour‑coded sections, and clear safety guidance for sulfur dioxide. Fully aligned to AQA GCSE Chemistry & Trilogy, ready to print and use immediately.
