Physical Science

TOPIC: Matter and Forms of Energy

CONTENT STATEMENT 1

  • All objects and substances in the natural world are composed of matter.

CONCEPTS

/ VOCABULARY
  • Matter takes up space and has weight.
* Distinguishing between mass and weight not appropriate for elementary grades.
  • Some forces act without touching, such as using a magnet to move an object(s) falling to the ground.
*Magnetic forces should be introduced through observation and experimentation only. Definitions of this force should not be the focus of the content statement. /
  • Matter
  • Weight

TOPIC: Matter and Forms of Energy

CONTENT STATEMENT 2

  • Matter exists in different states, each of which has different properties.

CONCEPTS

/ VOCABULARY
  • Most common states of matter are solids, liquids, and gases.
  • Shape and compressibility are properties that can distinguish between the states of matter.
  • The shape of a solid is independent of its container. Unless they are pushed or pulled on, solids retain their shape.
  • Liquids and gases flow and take the shape of the container.
  • One way to change matter from one state to another is by heating or cooling.
  • Objects can be separated or sorted based on their properties.

TOPIC: Electricity, Heat, and Matter

CONTENT STATEMENT 3

  • The total amount of matter is conserved when it undergoes a change.

CONCEPTS

/ VOCABULARY
  • When an object is broken into smaller pieces, a solid is dissolved in a liquid, or matter changes state (solid, liquid, gas), the total amount of matter remains constant.
  • Water changes from one state to another through heating or cooling.
