Objectives
Your team needs to show that it has a technical flair for designing electrical circuits. Can you draw accurate circuit diagrams as a ‘blueprint’ for your design?
Science Objectives
i) 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.
ii) Use recognised symbols when representing a simple circuit in a diagram.
Working Scientifically
- Record data and results of increasing complexity using scientific diagrams and labels.
- Identify scientific evidence that has been used to support or refute ideas or arguments.
Lesson Planning
Teaching
- Identify from circuit diagrams those circuits that will or won’t work.
- Draw an accurate circuit diagram.
- Research and explain why electrical components behave as they do in terms of resistance.
- Feed back on others’ designs.
- Use feedback to improve their own design.
- Understand how electrical components in their design work to the desired effect.
Activities
- Draw a circuit diagram with a summary of the brightness, volume and speed of components within it.
- Annotate their circuit diagram with explanations of the role of resistance in making components work.
- Feed back on other’s designs.
- Use feedback to improve their design.
Investigation - exploring, analysing secondary sources
Explore resistance through the use of various components.
Draw circuit diagrams.
