Contents
Outcomes
- Pupils can describe the difference between a series and a parallel circuit
- Pupils can appreciate the advantages and disadvantages of series and parallel circuits
Specification References
- 2.14 know that lamps and LEDs can be used to indicate the presence of current in a circuit
- 2.9 explain why a series or parallel circuit is more appropriate for particular applications including domestic lighting
- 2.10 understaned that the current in a series circuit dpends on the applied voltage and the number and nature of other components
Starter
See how much pupils have remembered from the third year electricity topic with the "how much do you remember about the thrid year electricity" quizet
Main Body of Lesson
The main body of the lesson consists of a modified Vince sheet which we've used for a while and some work with ammeters and voltmeters. This is an ideal time to ensure that they can use ammeters and voltmeters correctly. Ideally they would have simple ammeters and voltmeters rather than multimeters. There is a powerpoint with the relevant circuit diagrams on.
Plenary
Use the toaster link in the powerpoint to go to a circuit simulator and check understanding
OR
There is a quick 10 question plenary quiz in the shared folder (alternatively you can use it as a starter next lesson)
Homework
- Read 178-179 and answer questions - nice recap of last year and some meter questions
- Read 186-187 and answer questions - series parallel questions
