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 separated glasses a little bit to create a small gap for liquids to connect, water and oil started moving. In the end, we had oil in the top glass and water in the bottom glass. It was time to turn our structure upside down and watch the flow of these liquids again

This colourful 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; however, we can increase it by adding salt and sugar to it. In this experiment, we were adding a different amount of salt to each glass of water. When the salt dissolves, it increases the mass of water without changing the volume very much, which means that the saltwater solution's de
