We had a great time at William de Ferrers. We have been learning about properties and changes of materials this term and we were able to use what we have already learnt to help us seperate mixtures of different materials. We had a mixture of sand, salt and water that we needed to separate. First we filtered the mixture to remove the salt and then we used the Bunsen burners to evaporate the water, leaving the salt behind. We also learnt about reversible and irreversible changes.
