Potential difference - complete lesson (KS3)

A differentiated lesson based on the Activate 2 (P1.3) SOW but can be used for others. The lesson covers the meaning of potential difference and how to measure it, a brief mention of the key words 'series' and 'parallel' and their meaning, and a brief introduction to p.d. ratings on batteries. There is then class wide AFL with the use of planner (red, green and yellow) cards covering the information above. Students then progress to a simple practical activity where they measure p.d. across different components; battery packs, connection leads, voltmeters, bulbs and switches are required. A 'stretch' question sheet is included if students progress ahead of time, the answers for this are incorporated into the slides. The plenary is based on student reflection against the learning objectives, answers can be read out and 'pop corned' between peers.
