Grade 2 Science Unit 2

Structure & Properties of Matter

Suggested Timeframe: Winter (Jan-March)

Unit description: Students explore how to describe and classify different types of materials based on observable properties. They learn how heating and cooling can cause changes to solids and liquids, and that sometimes these changes are reversible, and sometimes they are not.

Essential Questions and Big Ideas

How do we describe 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 up from a small set of pieces. (2-PS1-3)

What are ways we can change matter?

    • 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)

Prerequisite Skills/Science & Engineering Practices

Plan and conduct an investigation to describe and classify, analyze data to make determinations, make observations to construct evidence-based accounts, construct an argument supported by evidence.
