pH Scale & Neutralisation | SEND GCSE Chemistry

Inclusive SEND science lesson on pH and Neutralisation for Key Stage 4 – one lesson with three pathways for PMLD, SLD / MLD and dyslexic GCSE learners. 44 slides at 28 pt, answers on click, worksheets with answers and 19 pages of print-ready cards. How acidic is lemon juice, and how alkaline is soap? An inclusive KS4 lesson on the pH scale, indicators and neutralisation for special schools and mixed-ability classes.

Everyone studies the same National Curriculum topic at the right level, so the whole class learns together.

Three pathways in one lesson

• Explore (PMLD / sensory learners): a sensory story with a sour lemon, slippery soap and rainbow indicator colours. Includes an Engagement Model observation record for the adult to complete.
• Build (SLD / MLD, low reading age, EAL): match pictures to words, sort acid, neutral and alkali and watch red indicator turn green – by sticking, pointing, signing or writing.
• Explain (GCSE, dyslexia-friendly): use the pH scale, write H⁺ + OH⁻ → H₂O, compare strong and weak acids and answer an exam question.
