This video from the Royal Society of Chemistry (RSC), aimed at primary teachers, demonstrates an experiment on density which may be used when learning about separating mixtures and the properties of liquids. Oil, water and an ice cube are all put in a clear container and the resulting levels compared. The oil floats on top of the water as it has a lower density and the ice-cube floats between the oil and the water as it has a density higher than oil but lower than that of water. The results of golden syrup, oil and water are also compared. Ideas for using this demonstration in class are discussed. They include: making predictions and explaining results and finding other liquids of differing densities to test and compare.
