HS-PS1-10
Use evidence to support claims regarding the formation, properties and behaviors of solutions at bulk scales.
Clarification statement: Examples of physical properties could include colligative properties, degree of saturation, physical behavior of solutions, solvation process and conductivity. Examples of solution types could include solid-liquid, liquid-liquid, and gas-liquid solutions. Concentrations can be quantitatively expressed in ppm, molarity, and percent by mass
Assessment boundary: Assessment of colligative properties is limited to qualitative statements of boiling point elevation and freezing point depression.
Note: this is a NYSED-specific performance expectation that is different from the Next Generation Science Standards.

NGSS Dimensions
Performance expectation HS-PS1-10 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Engaging in Argument from Evidence
- Evaluate the claims, evidence, and reasoning behind currently accepted explanations or solutions to determine the merits of arguments.
- PS1.A: Structure and Properties of Matter
- Solutions possess characteristic properties that can be described quantitatively and qualitatively.
- Patterns
- Different patterns may be observed at each of the scales at which a system is studied and can provide evidence for causality in explanations of phenomena.
