What is the role of testing? Why would Brunel have done it and why do we continue to do it in our science lessons? Can the children give examples of when Brunel had to test and re-test. What ELLI skill does this demonstrate?

Can they think of any times when more tests would potentially have been useful?

The future of marine propulsion?

‘Scrapheap challenge’ type activity where the children use recycled materials to create a simple propeller to push air or water. Consider the choice of objects and their  material properties (why were they used for their previous function? e.g. crisp packet / plastic bottle etc. How will they be useful to your propeller design?)

Consider health and safety issues and the tools available to complete the project.

Propeller: Blades mounted at the back of a ship underneath the water which drive an engine powered ship forward.

A very basic definition and diagram available at http://www.thefreedictionary.com/propeller

Demonstrate the principle of propulsion through a clip of a hovercraft (air propulsion)

Could go on to discuss/ investigate wind/tidal turbines which are propellers in reverse (used to generate electricity).

What links Brunel and the propeller? The steam ship SS Great Britain was the first ship to have an iron hull and employ screw propellers prompted a new era of ship design and propulsion.  

A history of Brunel’s ships is available at:

Can you design a workable model propeller?
