P-PS1-1

Ask questions and use observations to test the claim that different kinds of matter exist as either solid or liquid.

Clarification statement: Emphasis should be on observing and describing similarities and differences between solids and liquids based on their physical properties. Solids and liquids can be compared and categorized (sorted) based on those properties.

Note: this is a NYSED-specific performance expectation that is different from the Next Generation Science Standards.

NGSS Dimensions

Performance expectation P-PS1-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices

• Asking Questions and Defining Problems
  • Ask questions based on observations to find more information about the designed world.

Disciplinary Core Ideas

• PS1.A: Structure and Properties of Matter
  • (NYSED) Different kinds of matter exist and many of them can be either solid or liquid. Matter can be described, categorized, and sorted by its observable properties.

Crosscutting Concepts

• Patterns
  • Patterns in the natural and human designed world can be observed and used as evidence.

Connections to Other Standards

P-PS1-1 connections to ELA, math, and other science standards as outlined by the NYS Education Department:
