This video demonstrates an experiment which may be used when learning about changing state. Different kinds of liquid are frozen and the results observed and discussed. Pre-boiled water results in a mostly clear ice, salt water a cloudy ice, lemonade an ice full of holes and coloured water turns into an ice block with all of the colour pushed to the centre. This demonstration could be re-created with children making predictions about what may happen when different liquids are frozen then comparing this to the results and giving explanations.
