5-PS1-3 - Make observations and measurements to identify materials based on their properties.

Clarification Statement - Examples of materials to be identified could include baking soda and other powders, metals, minerals, and liquids. Examples of properties could include color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility; density is not intended as an identifiable property.

Assessment Boundary - Assessment does not include density or distinguishing mass and weight.

5-PS1-3 - Make observations and measurements of substances to describe characteristic properties of each, including color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility.

Clarification Statement - Emphasis is on describing how each substance has a unique set of properties. Examples of substances could include baking soda and other powders, metals, minerals, and liquids.

Assessment Boundary - Density, distinguishing mass and weight, or specific tests or procedures are not expected in state assessment.
