Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. Freezing means the solidification phase change of a liquid or the liquid content of a substance, usually due to cooling. This video contains great real world examples to explain how freezing occurs and the impact of freezing in the world
This video satisfies the 2-PS1-4 requirement for second grade proficiency.
Students who demonstrate understanding can:
