Objectives

Your amazing working electric personality is almost finished and you just need to add some finishing touches to make it look even better! Like all great inventors, you will need to evaluate your creation and make some notes for future improvements. There will also be time to take part in a quiz on electricity to find out just how much of an expert you have become!

Science Objectives
i) Construct a simple series electrical circuit, identifying and naming its basic parts, including cells, wires, bulbs, switches and buzzers.

Working Scientifically

  1. Identifying differences, similarities or changes related to simple scientific ideas and processes
  2. Reporting on findings from enquiries, including oral and written explanations, displays or presentations of results and conclusions

Other Curriculum Areas

Design and Technology - Evaluate

  • Evaluate their ideas and products against their own design criteria and consider the views of others to improve their work
  • Understand how key events (the age of electrical discovery) and individuals (Thomas Edison) in design and technology have helped shape the world

You Will Need

Additional Resources

  • The children’s part completed models and their Planning/Evaluation booklets from Session 4
  • Any extra resources required to complete the models
  • Electrical components
  • Wires stripped back 2cm at each end

Provided Resources

  • Quiz sheets

Lesson Planning

Teaching

  • Test and make improvements to a working model that uses an electrical circuit.
  • Report to others on the making of their model and the electrical circuitry it contains using appropriate technical and scientific vocabulary.
  • Evaluate its effectiveness and suggest possible improvements.


Activities

  • Take part in a quiz on electricity to assess their learning in this block (Yrs3&4)
  • Work on finishing their working electric model, focussing on technical and aesthetic qualities (Yrs3&4)
  • Evaluate their model by identifying positive features and points that could be improved (Yrs3&4)
  • Consult the opinions of others and record their views as part of the evaluation process (Yrs3&4)


Investigation
It’s time to create your electrical personality. Assemble the components to make a working feature. Use paint and collage to add details and accessories (exploring)
Year 3 /Year 4 working on their own designs. Expect more independence from Year 4s


Vocabulary
Electricity, circuit, switch, pressure, battery, device, motor, bulb, buzzer, component, wire, lead, crocodile clip, connection, power, cell, energy, flow, current, conductor, insulator, disconnect, design, test, adapt, modify
