In this water cycle activity you will be learning about some of the properties of water. You know that ice cubes float in water. In this intriguing activity, can you guess what happens when an ice cube floating in oil begins to melt?
The ice cube floats in the oil because water expands when it freezes and becomes lighter than the salad oil. As the ice cube melts and turns into a liquid it contracts.
The water becomes heavier than the salad oil forming round balls of water suspended in the salad oil as it drifts to the bottom of the container.
The water forms small balls of liquid because the water molecules are attracted to each other and not the oil. This causes surface tension to form on the outside of the water molecules. The shape they form, a ball, is the most compact shape it can form as it drifts down through the oil.
