Teaching air distillation in context
11 July 2012
Produced in partnership with BOC, the videos feature Keith, an applications engineer, and Sarah, a chemistry graduate who now works in marketing. Together they not only reveal the science involved, but also show the wider possibilities of a career in chemistry.
The video for 11+ students looks at the composition of the air, how BOC cleans it before separating it into its constituent gases and how they are delivered around the country. The 14+ video looks in detail at fractional distillation and the 16+ film investigates the importance of freezing food properly.
