AQA A Level lesson on the titration method (RP1): why each step matters, and from burette readings to a mean titre. Slides, sheets, answers.

Lesson 15 of a 23-lesson sequence on amount of substance. Prepares pupils for the required practical. Cycle 1 takes each step of the method and what would change without it. Cycle 2 reads burettes, records to 0.05 cm³ and chooses concordant titres for the mean.

Two teaching cycles, each with a worked example, a gap-fill, a hinge question, a completion problem, whiteboards and a timed independent task.

What’s included: a teacher PowerPoint with answers revealed on click and full speaker notes (timings, what to look for, what each wrong answer means); a pupil PowerPoint with the answers removed, ready to print; a worksheet, a support sheet, extra practice and full worked answers as editable Word documents.
