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

Try this fall density tower and see where your objects sink to! Why does this happen? This tower works by stacking liquids based on their weight compared to their size, AKA, stacking based on density! The heavier (denser) liquids sink to the bottom, while lighter ones float on top, creating colorful layers. | KiwiCo
