Why does ice float?

The video explains the importance of ice floating on water, highlighting its role in insulating aquatic life from extreme cold. It delves into the concept of density, explaining that ice floats because it is less dense than liquid water. The video further explores the unique molecular structure of water, which leads to its polarity and the formation of a less dense solid structure when frozen. This structure allows ice to float, providing a crucial insulating layer for aquatic organisms.

How do the molecular structures of water contribute to its unique properties?
