2. Restricted © Siemens AG 2015. All rights reserved I can see clearly now Overall learning objectives:  To gather and use data to construct Sankey diagrams to illustrate efficiencies and support conclusions.  To explain how light bulbs can transfer energy and the concepts behind different light bulb technologies, and to use ideas about reflection to design flood light reflector.  To evaluate the impact of different technologies on society and different technological approaches to a challenge.  To conduct cost benefit analysis and evaluate different solutions using set criteria.

3. Overall learning outcomes:  Students will have analysed two different sorts of bulb in terms of how they work and how energy efficient they are.  Students will have used ideas about reflectors to design and test one of their own to meet a particular brief.  Students will have decided how to apply multiple success criteria.
