Unifying Themes in Physical Science

Matter (Physical Science Unifying Concept A)
Matter has various states with unique properties that can be used as a basis for organization. The relationship between the properties of matter and its structure is an essential component of study in the physical sciences. The understanding of matter and its properties leads to practical applications, such as the capability to liberate elements from ore, create new drugs, manipulate the structure of genes and synthesize polymers.

Forces and Motion (Physical Science Unifying Concept B)
The laws of motion are used to describe the effects of forces on the movement of objects.

Energy (Physical Science Unifying Concept C)
The total energy of the universe is constant. All events involve the transfer of energy in one form or another. In all energy transfers, the overall effect is that the energy is spread out uniformly.
