What’s Included:

• DO NOW - Starter Activity
  Quick recap tasks help activate prior knowledge before introducing new concepts.

• 26-Slide Fully Animated PowerPoint
  Every key point and example appears one click at a time, guiding students through complex ideas at an accessible pace. Teacher-led animations allow you to pause, question and discuss before each reveal.

• Printable Student Handout (7 pages)
  Mirrors the slides in a “fill-in-the-blank” format. Students only need to copy the bolded key words from the slides to complete the gaps, rather than copying out full notes. This frees up lesson time for engaging with the content and practice exam questions, while the handout serves as high-quality notes that can be used for later revision.

• Exam Question Practice
  3 AQA past-paper questions with model answers (8, 4 and 8 marks).

• Exam Tips & Mark Allocation Guidance
  Breaks down how reliability is typically examined (mark ranges, most commonly tested angles and how it can surface inside longer “design a study” questions)
