Pupils who are secure will be able to:

• Recall a range of electrical appliances, classify them as mains or battery-powered and explain why.
• Explain how to test if a circuit works and identify when simple electric circuits will work.
• Identify symbols for open and closed switches and give examples of how switches are useful.
• 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.
• Describe that a material is a good electrical conductor when it is added to an electric circuit and the bulb lights and 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 and 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 and 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.
