Objectives

Take part in a Dragons’ Den briefing session and learn about the challenges that lie ahead as designers of festive lights and decorations with an electric buzz.

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

  1. Plan different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary.
  2. Report and present findings from enquiries, including conclusions, causal relationships and explanations of and degree of trust in results, in oral and written forms such as displays and other presentations.

Other Curriculum Areas
Design and Technology

  • Use research and develop design criteria to inform the design of innovative, functional, appealing products that are fit for purpose, aimed at particular individuals or groups. Understand and use electrical systems in their products.

Lesson Planning

Teaching

  • Plan electric circuit investigations to consolidate current electrical knowledge
  • Establish current understanding of electricity and approaches to working scientifically
  • Develop success criteria based on design brief

Activities

  1. Plan and carry out a series of simple electrical circuit investigations
  2. Identify current electrical knowledge and areas to explore further
  3. Create success criteria for their Dragons’ Den electrical challenge
