Science

Physical Science

Power Standards
  • Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose. (2-PS1-2)
  • Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot. (2-PS1-4)

Critical Content

Content and Skills

*Power Standard Content

PS1.A: Structure and Properties of Matter

  • Different kinds of matter exist and many of them can be either solid or liquid, depending on temperature. Matter can be described and classified by its observable properties. (2-PS1-1)
  • * Different properties are suited to different purposes. (2-PS1-2), (2-PS1-3)
  • A great variety of objects can be built from a small set of pieces. (2-PS1-3)
  • * Every human-made product is designed by applying some knowledge of the natural world and is build using materials derived from the natural world.

PS1.B: Chemical Reactions

  • * Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible, and sometimes they are not. (2-PS1-4)
