Electricity - Voltage and Potential Difference

Y7 - Electricity PPT and Worksheet Pack

Give your students a complete, carefully sequenced introduction to electricity with this **10‑lesson, ready‑to‑teach unit** designed for KS3 Science. Each lesson includes a clear PPT, structured modelling, retrieval practice and an accompanying worksheet to support all learners. The unit builds knowledge step‑by‑step, covering current, voltage, resistance, circuits and electromagnets, before applying learning to real‑world electrical safety. This pack is ideal for non-specialists, busy teachers and departments seeking consistency across KS3. ### **What’s Included** - **10 fully resourced lessons** (PPT + worksheet for each) - Clear, student‑friendly explanations and diagrams - Retrieval starters and low‑stakes checks - Practical skills: using ammeters, voltmeters, building circuits, testing variables - Real‑world applications: fuses, circuit breakers, motors, household safety - Designed for mixed‑ability Year 7 classes ### **Lessons in the Unit** 1. **What Is Electricity?** – Energy transfer, components, circuit symbols 2. **Series and Parallel Circuits** – Current pathways and circuit behaviour 3. **Electric Current** – Flow of charge, units, using an ammeter 4. **Voltage & Potential Difference** – The ‘push’ in circuits, using a voltmeter 5. **Resistance** – Opposition to flow, conductors vs insulators 6. **Factors Affecting Resistance** – Length, thickness, data analysis 7. **Voltage, Resistance & Current** – Qualitative V–I–R reasoning 8. **Brightness, Current & Voltage** – Comparing series and parallel circuits 9. **Electromagnets** – Magnetic fields, building and strengthening electromagnets 10. **Electricity in the Home** – Safety devices, hazards, applying circuit knowledge ### **Why Teachers Love This Unit** - Clear progression from basics to application - Consistent structure across all lessons - Accessible explanations for EAL and lower‑attaining learners - Stretch questions and reasoning tasks for higher‑attaining pupils - No‑prep, print‑and‑teach format This bundle provides everything you need for a confident, engaging and curriculum‑aligned KS3 Electricity unit — perfect for departments aiming for high‑quality, consistent delivery.
