What you'll learn
- What Are Solids and Liquids?. Most things get denser when they freeze solid—but water does the opposite. Ice is less dense than liquid water, which is why ice cubes float.
- Density and Why Things Float. Most ancient peoples noticed that ice bobs up in water, but they had no language for why—they just saw it happen.
- Why Ice Floats: The Complete Picture. Water is denser than ice, so ice floats—and this happens because of how water molecules arrange themselves when they freeze. Most solids are denser than their liquid form.
Questions this course answers
What is density?

How do particles behave in a liquid?
Particles in a liquid are close together but free to move around and slide past each other.
Why do some objects sink in water?
Objects sink because they are denser than water with lots of mass squeezed into a small volume.
