Systems and Matter


Essential Question(s)

How do you depend on systems in everyday life?

Content Learning Targets

  • Matter has properties (color, hardness, odor, sound, taste, etc.) that can be observed through the senses
  • Objects have properties that can be observed, described, and/or measured: length, width, volume, size, shape, mass or weight, temperature, texture, flexibility and reflectiveness of light
  • Objects and/or materials can be sorted or classified according to their properties
  • Matter exists in three states: solid, liquid, gas
    • solids have a definite shape and volume
    • liquids do not have a definite shape but have a definite volume
    • gases do not hold their shape or volume
  • Some properties of an object are dependent on conditions of the present surroundings in which the object exists:
    • temperature (hot or cold)
    • temperature can affect the state of matter of a substance
    • moisture (wet or dry)
  • A system is a group of objects that interact
    • example: flashlight - none of the components of a flashlight have common properties. The only thing they have in common is that they interact to produce light
  • Energy can vary in form, amount, and ability to move through materials and space
    • energy can exist in several forms, such as mechanical, magnetic, and chemical
    • energy can move from one object to another, through materials and through space. Mechanical energy can be transferred from one point in space to another point
    • the amount of energy available from a source can vary
  • Interaction between matter and energy can create motion (paddle boats)
  • The amount of change in the motion of an object is affected by friction
