Complete GCSE Physics lesson on Density & the Density Required Practical for AQA, Edexcel & OCR – 40 editable slides + differentiated worksheets with full answers. Why does a steel ship float but a steel bolt sink?

Lesson 1 of the P3 Particle Model of Matter unit. Suitable for Combined Science (Trilogy) and Triple Physics, Foundation and Higher tiers. Just open and teach – every slide, worksheet and answer is done for you. Covers the required practical: density.

What’s included

• 40-slide editable PowerPoint – every word at least 28 pt, so it reads clearly from the back of the room (great for SEN, dyslexia and visual impairment)
• Do Now retrieval starter with answers, a picture hook, I do / we do / you do worked examples, equation cards and clear original diagrams
• Mini-whiteboard quiz, an illustrated hinge question with explained answers, and click-by-click answer reveals
• Exam-style question with mark scheme and sentence starters, 3-2-1 exit ticket, homework and glossary
• Clickable countdown timers and full teacher notes (spec match, 60-minute lesson plan, common misconceptions)
• 6-page differentiated worksheet pack (Word + PDF) – Bronze, Silver and Gold tasks, a stretch challenge, exam question, exit ticket and full answers and mark schemes

Learning objectives

• Bronze: Recall and use ρ = m ÷ V. Describe particle arrangements in solids, liquids and gases.
• Silver: Convert between g/cm³ and kg/m³; rearrange for m and V. Measure the density of regular and irregular solids and liquids.
• Gold: Explain density differences using particles. Evaluate sources of error in the practical.

Specification

• AQA GCSE Physics 8463 / Combined Science Trilogy 8464 – 4.3.1.1
• Edexcel GCSE Physics 1PH0 / Combined Science 1SC0 – matching topic content
• OCR Gateway Physics A J249 / Combined Science A J250 – matching topic content

Key words: density, mass, volume, kg/m³, g/cm³, displacement, meniscus, regular, irregular
