3.PS1: Matter and Its Interactions

3.PS1.A: Structure and Properties of Matter

3.PS1.A.1: Predict and investigate that water can change from a liquid to a solid (freeze), and back again (melt), or from a liquid to a gas (evaporation), and back again (condensation) as the result of temperature changes.

3.LS3.C: Adaptation

3.LS3.C.1: Construct an argument with evidence that in a particular ecosystem some organisms—based on structural adaptations or behaviors—can survive well, some survive less well, and some cannot.
