Watch each groups adverts and discuss which ideas are already in use and what would still need to be tested? How valid an idea is it what process would need to be gone through to ascertain this?
Discuss the function of a turbine further and consider new and original ways of using turbines to power objects / transport.
Children are to discuss their ideas and record on whiteboards as they work. Every few minutes have a 30-second feedback session to share ideas along the way and help them to become more fully developed.
Set up a group project - to design a TV advert for the steam turbine – ‘20 things you could do with a steam turbine!’
Look at demonstration of how a steam engine works:
‘How do steam engines work? Fire heats the water, the water turns to steam, the steam pushes the piston and that motion is converted into the required movement - like turning a wheel. Did you know that steam power is not dead? Today 80 per cent of our electricity is generated by steam turbines. ‘ [taken from www.thinktank.ac]
Robert Stephenson (best steam locomotive designer in Britain at the time with ‘The Rocket’) – what was his role in the Victorian times and how was it informed / competed with / duplicated by Brunel’s work?
How could the principles of a steam engine be usefully employed today?
