Inclusive SEND science lesson on Density for Key Stage 4 – one lesson with three pathways for PMLD, SLD / MLD and dyslexic GCSE learners. 45 slides at 28 pt, answers on click, worksheets with answers and 19 pages of print-ready cards. Why does a cork float and a stone sink? An inclusive KS4 lesson on density, including the required practical, 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: float and sink in a water tray. Includes an Engagement Model observation record for the adult to complete.
• Build (SLD / MLD, low reading age, EAL): match pictures to words, decide float or sink and read a balance – by sticking, pointing, signing or writing.
• Explain (GCSE, dyslexia-friendly): use density = mass / volume, measure volume by displacement and answer an exam question.

• 45-slide editable PowerPoint – every word at least 28 pt, cream background, no italics, one idea per slide, a picture on every teaching slide and answers revealed one click at a time
• Visual timetable with Now / Next, feelings check-in, sensory starter, ‘I can’ objectives, key words with pictures, show-me checks, picture hinge question, exam question with mark scheme and plenary
• Multi-sensory practical: measure the density of regular and irregular objects
