Physics/History GCSE: The invention of the telephone and how it changed society
Michael Mosley, Cassie Newland and Mark Miodownik describe the scientific achievements of Alexander Graham Bell.
Following the telegraph the race was on to turn speech into an electrical signal.
In 1876 Alexander Graham Bell did so and patented the first telephone. An animation is used to show how electromagnets are used in this invention.
The social reasons behind the slow adoption of this invention into society are then discussed.
This clip is from the series The Genius of Invention.
This clip would be ideally suited to showing students the significant achievements of Alexander Graham Bell.
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.
