5th Grade•35 minutes•NGSS 5-PS1-1
Learning Objective
I can describe how water changes from a solid to a liquid to a gas.
Key Concepts
Matter can be grouped into three main states: solid, liquid, or gas.
Mass is the amount of matter in an object, while volume is how much space that matter takes up.
When water is frozen, it is a solid; when it melts, it is a liquid; and when it evaporates, it becomes a gas.
