  Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
• 2-PS1-2
  Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.
• 2-PS1-3
  Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and made into a new object.
• 2-PS1-4
  Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
