Pupils who are secure will be able to:

• Recall a range of electrical appliances and classify them as mains or battery-powered.
• Explain why something is either mains or battery-powered.
• Explain how to test if a circuit works and identify when simple electric circuits will work.
• Identify symbols for open and closed switches.
• Predict whether a circuit will work based on whether the switch is open or closed and explain that it works by breaking and completing a circuit.
• Give examples of how switches are useful.
• Describe that a material is a good electrical conductor when it is added to an electric circuit and the bulb lights.
• Describe that a material is a good electrical insulator when it is added to an electric circuit and the bulb does not light.
• Recall that metals, for example, are good electrical conductors and plastics, for example, are good electrical insulators.
• Describe that the more bulbs added to a series circuit, the dimmer the bulbs will be.
• Explain that the bulbs will be dimmer when more are added to a circuit, as less energy is transferred to each of them.
• Describe precautions for working safely with electricity.
• Explain some precautions using knowledge of circuit diagrams, electrical components, conductors or insulators.

When working scientifically, pupils who are secure will be able to:

• Draw a results table and record a range of appliances under the correct headings ‘Mains’ or ‘Batteries’.
  
• Identify and draw simplified electric circuit symbols and use these to draw a simplified circuit diagram.
• Write a method for the investigation that considers appropriate equipment, ordering clearly written steps and considering safety.
• Pose questions relating to bulbs in an electrical circuit.
• Explain why a selected question is testable.
• Suggest that new inventions will change safety advice.
