How can we use models to help us think about electricity? Key terms: current, conductor, insulator 26 February 2018 Secure: Exceed: Develop: I can use a model to describe how an electrical circuit works . Starter: Identify the components in the following circuits. I can define the terms: conductor and insulator and give some examples of each I can evaluate the use of models in Science.
STARTER: What components are in this circuit? 3V BatteryLight bulbSwitchWires
EXTENSION: What does an ammeter measure?
What is a conductor? If the centre of this wire is a conductor, what must it do?What types of material might be conductors?
The plastic coating on a wire is known as an insulator.What do you think an insulator does? What is a insulator?
TASK: Applying your learning BronzeSilverGold Define the terms electrical insulator and electrical conductor.Describe the terms electrical insulator and electrical conductor giving examples.Explain how both conductors and insulators are used in wiring for electrical appliances. M – class bookI – individually N – quietlyT – 8 mins EXTENSION: Explain what would happen if we did not have an insulating material on wires.
How are models used to help us think about electricity?
How are models used to help us think about electricity? Cell / battery – Transfers energy to the charges and pushes them around wire.Wire – All of the charges stay in the wires.Bulb – Energy is transferred to the room by light and heat.
TASK: Applying learning BronzeSilverGold Label the parts that represent the battery, wires and bulb and describe how. Use the help sheet descriptions to label your diagram showing how the central heating system models a circuit.Label each component of the model and explain in your own words how it represents a circuit. M – diagramI – individually N – quietly T – 10 mins EXTENSION: Explain why we use models to help us to explain circuits. Stick in your diagram

The boiler transfers heat energy to the waterThe pump pushes the water through the pipes All the water stays in the pipesPipes let water flow through themWater flows through the pipesIf you measured the amount of water flowing, you would get the same answer everywhere in the central heating systemThe water has the most energy when it has just left the boiler, and least energy when it returns to the boiler. In the radiator, energy is transferred from the hot water to the room by heating The boiler transfers heat energy to the water The pump pushes the water through the pipes All the water stays in the pipesPipes let water flow through themWater flows through the pipesIf you measured the amount of water flowing, you would get the same answer everywhere in the central heating system The water has the most energy when it has just left the boiler, and least energy when it returns to the boiler.In the radiator, energy is transferred from the hot water to the room by heating
