Entering the dragons' den
Science Year 6
This unit is part of
Year 6 Science Electric Celebrations
Objectives
It’s time for some final tweaks before entering the Dragons’ Den. You will need to impress the dragons with your scientific know-how and the rigorous testing processes you have adopted. Good luck!
Science Objectives
i) Associate the brightness of a lamp or the volume of a buzzer with the number and voltage of cells used in the circuit.
ii) 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.
iii) Use recognised symbols when representing a simple circuit in a diagram.
Working Scientifically
- 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.
- Identify scientific evidence that has been used to support or refute ideas or arguments.
Other Curriculum Areas
Design and Technology
- Evaluate ideas and products against design criteria and consider the views of others to improve their work; understand and use electrical systems in their products.
Extended Writing Opportunity
Persuasive writing: Write up the research and development of your festive lights decoration in order to persuade the Dragons that yours is the best.
Lesson Planning
Teaching
- Present findings from prior investigations through presentation.
- Evaluate and make improvements on prototype.
- Present a working prototype, explaining how it works and how it meets the design criteria.
Activities
- Demonstrate how their decoration works and to link their circuits to their diagrams.
- Link findings from previous electrical investigations to their circuits.
- Outline how their design meets all success criteria.
- Demonstrate electrical knowledge and skills through presentation.
