Dr. Boyd gives the physics definition of density, then walks you through a demonstration to show how liquids with different densities can form multiple liquid layers in a container.

We are observing the different densities of the liquids (coloured water, honey and oil) versus the different densities of the objects (marble, grape, legobrick and foam cube).

Simple density experiments you can try in your kitchen now. We started by putting a glass of water on top of a glass of vegetable oil. That is a cool experiment on its own, but let's focus on density here. After we moved the card that...

This saltwater density tower experiment will help you and your children understand density better. Density is the mass of a material per unit volume, and it is a fixed number for each material. The density of water is 997 kg/m³;...

You'll have to try this fun kids science experiment to see what happens when you layer liquids of different densities. Making an impressive 8 Layer Density Tower Experiment requires an understanding of density. Let me...
