Electricity
National curriculum content
- Associate the brightness of a lamp or the volume of a buzzer with the number and voltage of cells used in the circuit
- Compare and give reasons for variations in how components function, including the brightness of bulbs, the loudness of buzzers and the on/off position of switches
- Use recognised symbols when representing a simple circuit in a diagram
Lesson objectives
- Explain the importance of the major discoveries in electricity
- Create a circuit diagram using the correct symbols
- Describe how we can change the brightness of a bulb or the loudness of a buzzer
- Demonstrate how we can alter the current in a circuit
- Create a game that uses an electrical circuit
- Create a game that uses an electrical circuit
- Generate an explanation text
What we want children to know
- How to represent a simple circuit in a diagram using recognised symbols
- Which symbols represent each component in a circuit diagram
- How voltage affects the brightness of a bulb or the volume of a buzzer
- Key events and inventions in the history of electricity
- That current is the flow of electricity around a circuit
What skills we want children to develop
- Plan different types of scientific enquiries to answer questions
- Construct simple series circuits
- Take measurements, using a range of scientific equipment, with increasing accuracy and precision
- Use test results to make predictions to set up further comparative and fair tests
- Report and present findings from enquiries
- Identify scientific evidence that has been used to support or refute ideas or arguments
