PS.5 a - Matter & Energy Relationships

The student will investigate and understand changes in matter and the relationship of these changes to the Law of Conservation of Matter and Energy. Key concepts include

a) physical changes.

Bloom's Levels:  Analyze; Understand

Adopted: 2010


  • Matter can undergo a variety of changes, both physical and chemical.

  • I can explain why my car can be repaired after an accident, but not if it caught fire.


  • Matter can undergo physical and chemical changes. In physical changes, the chemical composition of the substances does not change. In chemical changes, different substances are formed. Chemical changes are often affected by the surface area/volume ratio of the materials involved in the change.


In order to meet this standard, it is expected that students will

a-c)  compare and contrast physical, chemical, and nuclear changes.

design an investigation that illustrates physical and chemical changes.
