small set of pieces. (2-PS1-3)
Learning Targets:
 I can identify the three states of matter,
solids, liquids and gases. (PS1.A)
 I can describe and classify solid objects by
their observable properties. (PS1.A)
 I can describe and classify liquids by their
observable properties. (PS1.A)
 I can provide evidence that an object made
of a small set of pieces can be disassembled
and made into a new object. (PS1.A)
 I can describe how different properties are
used for different purposes. (PS1.A)

NGSS Performance Expectations
Students who demonstrate understanding can:
2-PS1-1. 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
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
2-PS1-4. Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
