You'll see how warm and cold water interact and learn about density currents that occur in oceans and atmosphere ... Notice how the demonstrator uses a simple drinking straw to create distinct layers, ...

To do that requires farmers eliminate subsurface density layers resulting in the free flow of water, nutrients and roots through the soil explains Isaac Ferrie, Farm Journal Associate Field ...

Create a colorful tower of liquids that stack on top of each other based on their densities. This experiment demonstrates how different liquids have different densities and why some liquids float ...

The density of an object or substance is its mass divided by its volume: Density = Mass ÷ Volume. The units of density depend on the units used for mass and volume, but are usually: g/cm³ (if ...
