In science we are currently learning about properties and changes to materials. So far we have explored properties of common materials and solubility. Leading on from solubility we have learnt about separating mixtures, including filtration and evaporation. Today we made crystals by dissolving salt in boiling water and using a suspended paper clip in a glass jar to enable a crystal to form. We look forward to checking the progress of our green, red and yellow crystals over the coming days!
