Inclusive SEND science lesson on Reaction Time Required Practical for Key Stage 4 GCSE Biology (B5 Homeostasis and Response) – one lesson with three pathways for PMLD, SLD / MLD and dyslexic GCSE learners. 32-slide editable PowerPoint with answers on click, a 6-page worksheet pack with answers (Word + PDF) and a 19-page printable cards pack.

Big question: Can we make our reactions faster?

Everyone works on the same topic at the right level, so the whole class learns together.

Three pathways in one lesson

• Explore (PMLD / sensory learners): explore catching; show what I like. Includes the sensory story “Catch It!”.
• Build (SLD / MLD, low reading age, EAL): catch a ruler and read the number; say what reaction time is.
• Explain (GCSE, dyslexia-friendly): plan a fair test; calculate a mean and explain my results.
