Module: Properties and States of Matter
DCI: PS1.A (A) – Structure and Properties of Matter – Different
kinds of matter exist and many of them can be either solid, liquid, depending
on the temperature. Matter can be described and classified by its observable
properties.
PE: 2-PS1-1 Plan and conduct an investigation to describe and
classify different kinds of materials by their observable properties.
[Clarification
Statement: Observations could include color, texture, hardness, and
flexibility. Patterns could include the similar properties that different
materials share.]
The ideas in this standard:
- matter exists in several forms
- matter can be solid or liquid
- the state of matter depends on temperature
- matter can be described and classified by its observable properties
We can get quite a bit of mileage out of the PE. Students are expected to be able to classify materials based on their properties. We can do this by providing a list of materials, and their properties. Then, they can group several materials by a certain property or can even identify an unknown material based on its properties.
Possible Question Starters:
"Whether a material is a solid or liquid depends on the material's - "
correct answer - temperature
