Complete No-Prep lesson with exam questions, tasks and answers on Resistors and Ohm’s Law (ohmic and non-ohmic conductors, filament lamps, diodes, LDRs and thermistors) for AQA GCSE (9-1) Science / Physics. This is the third lesson in the teaching sequence.
This lesson covers all of AQA GCSE Physics 4.2.1.4 / Combined Science 6.2.1.4 theory sections but does not give instructions, sample results etc for the required practical.
As a Secondary Science teacher, Deputy Headteacher, writer and examiner for many years I make high quality no-prep lessons so busy teachers can teach outstanding lessons without spending hours planning. This high quality lesson includes explanations, different types of in-lesson assessment (all with answers) and unique exam questions.
My lessons are ideal for non-Physicists - as a Biologist who retrained as a Physics teacher I know how to take learners on a journey that builds up their understanding step by step, while still going into a lot of depth. The preview video shows a representative sample of slides from the resource so that you get a good idea of what it includes before you buy.
What’s Included:
• Starter / Do Now Activity
• Explanation slides in “chunked” sections with animated diagrams.
• Worked examples of calculations / questions.
• Multiple questions in different question styles and difficulties - no need for worksheets. Each “chunked” explanation section typically includes a set of “learning check / quick questions” followed by a set of in-depth questions on the learning from that “chunk” of the lesson. All questions have answers.
• Exam-style questions on the whole lesson at the end of the lesson- these are unique, based on real exam questions but not just copied from exam boards.
• Answers for all questions
• All easily editable to adapt to your teaching or to use in existing lessons.
• Slightly humorous, at points, if you like that sort of thing.
Learning objectives:
- Describe that for some resistors resistance is constant as current changes, but for others resistance changes as current changes.
- Describe Ohm’s Law and what is meant by an ohmic conductor.
- Explain the shape of the current-potential difference graphs for fixed resistors, lamps, diodes.
- Describe how resistance changes with light or temperature in LDRs and thermistors, and their uses.
The lesson was written for AQA GCSE Science / Physics but is very likely to be applicable to other exam specifications.
