This week our Year 9’s have been learning all about separation techniques including filtering and distillation. This technique allows us to extract water from sea water! Here you can see J. Jeremy of 9A2 collecting water that we had separated from sandy, salty water. First we filtered it using a filter paper and funnel to separate the sand from the salty water. Then we boiled it to change the state of the water from a liquid into a gas and then condense it to turn the gaseous water vapour into liquid water, leaving the salt behind in the round bottom flask.
Bear Grylls eat your heart out. Our pupils have all the skills they need for whatever life throws at them!
