Restricted © Siemens AG 2013 All rights reserved.siemens.co.uk/education Topic 2: Let there be light Siemens Education

Restricted © Siemens AG 2013 All rights reserved. Let there be light Overall learning objectives:  Understand how creative thinking and scientific ideas can be harnessed to solve problems and improve quality of life  Understand how natural resources can be used to provide useful services  Apply ideas about generating and using electricity to powering circuits

Restricted © Siemens AG 2013 All rights reserved. Let there be light Overall learning outcomes:  To explain how electricity can be produced and used  To suggest advantages it offered  To apply ideas about circuits to solve problems and develop solutions

Restricted © Siemens AG 2013 All rights reserved. Let there be light How could you make electricity?

Restricted © Siemens AG 2013 All rights reserved. Let there be light Turn to make light

Restricted © Siemens AG 2013 All rights reserved. Let there be light Other ways of using this idea Sketch your ideas for other items that could work using a hand crank method
