Quarry Bank Mill in Cheshire was built in 1784 and was one of the first water-powered cotton mills of the Industrial Revolution. While the machines are now powered by electricity, the water wheel still turns and the machines run. Linking the two are cogs, shafts and belts, so it is possible to see how the power of the river was captured and then transferred through the floors to the different machines, each one with its own combination of cogs and belts. The Learning Team at Quarry Bank believe that a visit to the site should be a fun multisensory experience that stimulates children's excitement and curiosity in a way that cannot easily be replicated in the classroom. In this article, the author describes a Science Technology Engineering and Mathematics (STEM) workshop at Quarry Bank Mill.
