TED-Ed: Why does ice float in water? - George Zaidan and Charles Morton

The video explores the critical role of water in life, emphasizing its unique properties. It explains why ice floats due to its lower density compared to liquid water, a result of hydrogen bonding. The molecular structure of water and the behavior of its molecules at different temperatures are discussed. The video highlights the ecological and environmental significance of floating ice, including its impact on marine life and climate regulation.

Discuss the role of hydrogen bonds in the properties of water.
