Density is a measurement of mass relative to the volume of an object! A small rock has more density than a large rubber raft which is why the rock would sink in water and the rubber raft will float. You can calculate the density of an object using the following equation: density = mass/volume.
In this activity you will explore the densities of liquids and see if you can layer them without them mixing!
Watch as Miss Amelia demonstrates how to layer liquids that are different densities.
