Science and Technology/Engineering | Grade : 5
Discipline - Physical Science
Core Idea - Matter and Its Interactions
[5.PS.1.4] - Conduct an experiment to determine whether the mixing of two or more substances results in new substances with new properties (a chemical reaction) or not (a mixture).
[W.5.2] -
Write informative/explanatory texts to examine a topic and convey ideas and information clearly.
[5.PS.1.2] -
Measure and graph the weights (masses) of substances before and after a reaction or phase change to provide evidence that regardless of the type of change that occurs when heating, cooling, or combining substances, the total weight (mass) of matter is conserved. Clarification Statement: Assume that reactions with any gas production are conducted in a closed system. State Assessment Boundary: Distinguishing mass and weight is not expected in state assessment.
[5.PS.1.3] -
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 Statements: 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.
State Assessment Boundary: Density, distinguishing mass and weight, or specific tests or procedures are not expected in state assessment.
