This activity is suitable for preschoolers to investigate the behaviour of two common household products (oil and water). The emphasis is on supporting children to develop their inquiry skills to describe what they observe when trying to mix these liquids. Preschoolers should be given the opportunity to communicate (describe and explain) their observations. The activity can be extended to Foundation, Year 1 and Year 2 students who should be encouraged to predict what will happen, communicate (explain) why some of the liquids used do not mix, as well as to describe the changes they observe when mixing materials. All children can complete an extension activity by adding detergent to explore the effect it has.
