Physics/History GCSE: The invention of the turbine
Michael Mosley, Cassie Newland and Mark Miodownik describe the scientific achievements of Charles Parsons.
He further developed Faraday’s dynamo to build a better, more reliable engine.
He wanted a one-step engine, not a two-step one to increase efficiency and so developed the rotary engine in 1884.
He developed a double set of blades to extract more energy from same steam, and a narrowing gap between blades to mean they move faster.
This clip is from the series The Genius of Invention.
This clip would be ideally suited to showing students the significant achievements of Parsons.
It could set the scene for a project on this or other famous historical scientists.
Students could stain their written work with tea bags to make it look as if it were written many years ago.
This clip will be relevant for teaching Physics and History. This topic appears in OCR, Edexcel, AQA, WJEC KS4/GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 4/5 in Scotland.
