Demonstrate how liquids can float on top of one another in a density column.
Density is defined as how much ‘stuff’ is packed into a particular area. A denser object weighs more than the same amount of a less dense object. Liquids that have a higher density, such as syrup, will sink below liquids with a lower density, such as water and oil. Solid objects also range in their densities. They sink into the liquid layers, resting at different levels depending on their density.

Love to Investigate is a set of 126 scientific investigations that encourage children to be curious, ask questions and explore the world around them.
Our series of practical, exciting investigations cover tricky topics in new and unusual ways, including evolution, mechanisms and air resistance. All activities come with background knowledge for teachers who haven’t taught the topic before and method boards to help children work more independently.
