# The Standards

### Matter and Its Interactions

#### Students who demonstrate understanding can:

Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved. 5-PS1-2

Clarification Statement and Assessment Boundary

Clarification Statement: Examples of reactions or changes could include phase changes, dissolving, and mixing that form new substances.

Assessment Boundary: Assessment does not include distinguishing mass and weight.

##### Science and Engineering Practices

Using Mathematics and Computational Thinking

Mathematical and computational thinking at the 3–5 level builds on K–2 experiences and progresses to extending quantitative measurements to a variety of physical properties and using computation and mathematics to analyze data and compare alternative design solutions.

##### Disciplinary Core Ideas

PS1.AStructure and Properties of Matter

PS1.BChemical Reactions

##### Crosscutting Concepts

Scale, Proportion, and Quantity

###### Connections to Nature of Science

Scientific Knowledge Assumes an Order and Consistency in Natural Systems

### Common Core State Standards Connections

ELA/Literacy
• W.5.7 - Conduct short research projects that use several sources to build knowledge through investigation of different aspects of a topic. (5-PS1-2)
• W.5.8 - Recall relevant information from experiences or gather relevant information from print and digital sources; summarize or paraphrase information in notes and finished work, and provide a list of sources. (5-PS1-2)
• W.5.9 - Draw evidence from literary or informational texts to support analysis, reflection, and research. (5-PS1-2)
Mathematics
• 5.MD.A.1 - Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems. (5-PS1-2)
• MP.2 - Reason abstractly and quantitatively. (5-PS1-2)
• MP.4 - Model with mathematics. (5-PS1-2)
• MP.5 - Use appropriate tools strategically. (5-PS1-2)
