PS1.A: Structure and Properties of Matter
Measurements of a variety of properties can be used to identify materials. (Boundary: At this grade level, mass and weight are not distinguished,
and no attempt is made to define the unseen particles or explain the atomic-scale mechanism of evaporation and condensation.) (5-PS1-3)
PS1.B: Chemical Reactions
When two or more different substances are mixed, a new substance with different properties may be formed.
