# The Standards

### Matter and Its Interactions

#### Students who demonstrate understanding can:

Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. MS-PS1-2

Clarification Statement and Assessment Boundary

Clarification Statement: Examples of reactions could include burning sugar or steel wool, fat reacting with sodium hydroxide, and mixing zinc with hydrogen chloride.

Assessment Boundary: Assessment is limited to analysis of the following properties: density, melting point, boiling point, solubility, flammability, and odor.

##### Science and Engineering Practices

Analyzing and Interpreting Data

Analyzing data in 6–8 builds on K–5 experiences and progresses to extending quantitative analysis to investigations, distinguishing between correlation and causation, and basic statistical techniques of data and error analysis.

### Common Core State Standards Connections

ELA/Literacy
• RST.6-8.1 - Cite specific textual evidence to support analysis of science and technical texts. (MS-PS1-2)
• RST.6-8.7 - Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table). (MS-PS1-2)
Mathematics
• 6.RP.A.3 - Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. (MS-PS1-2)
• 6.SP.B.4 - Display numerical data in plots on a number line, including dot plots, histograms, and box plots. (MS-PS1-2)
• 6.SP.B.5 - Summarize numerical data sets in relation to their context. (MS-PS1-2)
• MP.2 - Reason abstractly and quantitatively. (MS-PS1-2)
