Simple mixtures physical chemistry
WebbIn fact, most chemistry experiments have some sort of separation in them. Whilst some mixtures need more involved methods, often we can physically separate solids from a mixture with liquids. Have a go with your learners and try different mixtures and separation equipment, like coffee filter paper, different sized sieves, and tea strainer.
