Disciplinary Core Ideas
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 up from a small set of pieces. (2-PS1-3)
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)
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. [Clarification Statement: Observations could include color, texture, hardness, and flexibility. Patterns could include the similar properties that different materials share.]
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.* [Clarification Statement: Examples of properties could include, strength, flexibility, hardness, texture, and absorbency.] [Assessment Boundary: Assessment of quantitative measurements is limited to length.]
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. [Clarification Statement: Examples of pieces could include blocks, building bricks, or other assorted small objects.]
2-PS1-4. Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot. [Clarification Statement: Examples of reversible changes could include materials such as water and butter at different temperatures. Examples of irreversible changes could include cooking an egg, freezing a plant leaf, and heating paper.]*

l. Goals:
Essential Questions:
ll. Introductory Activities to Assess Prior Knowledge
A. Simple Activities - that assess students’ understanding of the phases of matter.
States of Matter - Matching (K-4)
B. Analyzing Matter: Give students 5 objects to "analyze," i.e. sponge, block of wood, wax candle, ball of yarn, square of cheese. Ask them to:
Analyzing Matter Activity
C. Brainstorming Session
Question: Thinking about materials and their properties.
1. Break students down into groups of 3-4.
2. Ask students to generate a list of the different materials that exist is at least two phases (liquid, solid, gas).
3. Discuss
Inquiry related to state of matter.
Rain Making Activity - The Water Cycle
Cloud Making Activity - How Do Clouds Form?
V. Summarize Knowledge - Enduring Understandings
When you research information you must cite the reference. Citing for websites is different from citing from books, magazines and periodicals. The style of citing shown here is from the MLA Style Citations (Modern Language Association).
When citing a WEBSITE the general format is as follows.
Author Last Name, First Name(s). "Title: Subtitle of Part of Web Page, if appropriate." Title: Subtitle: Section of Page if appropriate. Sponsoring/Publishing Agency, If Given. Additional significant descriptive information. Date of Electronic Publication or other Date, such as Last Updated. Day Month Year of access < URL >.
