Lesson 7Jc: Series and parallel Learning objectives Exemplar teaching activities Differentiation Resources Maths skills Practical skills Developing Explain how switches and broken bulbs affect a circuit. Identify common circuit components and their symbols. Model circuits using simple circuit diagrams. Measure current and state its unit. State what is meant by series circuit, parallel circuit. Securing Construct a circuit from instructions provided in the form of a circuit diagram. Describe how changing the number or type of components in a circuit affects the current. Recall the differences between how current behaves in series and parallel Starter: Series and parallel circuits Set up a series circuit with two bulbs and a parallel circuit with two bulbs and ask students to list the differences between them. Remove/add a bulb from each circuit and elicit the differences. Exploring: Switches in parallel circuits Ask students to build a series circuit with one switch and two bulbs and then ask them if they can use a second switch to turn just one bulb on or off. Explaining: 7Jc Using tables Introduce the use of tables for Exploring: Switches in parallel circuits Challenge students to make a circuit with two bulbs and two switches that can be switched independently. Resources from 7Jc Exploring Science. n/a Students build a series circuit with one switch and two bulbs. Ask them if they can use a second switch to turn just one bulb on or off.
