Science assembly

Science assembly
Mr Hawksley and Mr Bee.
Friday 17th July 2015 by C. Freeman

Students saw a super-quick way of making ice cream in assembly when Mr Hawksley froze some using dry ice! He talked to the students about the properties of dry ice, which is solid carbon dioxide. When pellets are placed in water it sublimates, meaning that it changes from a solid to a gas with no intervening liquid stage. The result is billowing dense clouds of smoke like fog. To demonstrate its intense freezing properties Mr Hawksley put whipped cream, carnation milk and flavourings into a food mixer then added dry ice which then froze the mixture within seconds. The vice principals tested the resulting mixture.

During the assembly it was also announced the £875 was raised for charity by today’s mufti day. Thank you to everyone that contributed.
