5-PS1-2: Conservation of Matter
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. (Scale, Proportion, and Quantity)
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.
The following assessments were created by science teachers hoping to better understand the NGSS. In most cases teachers went from standard to assessment in around an hour. These are drafts and should be used accordingly. Feel free to improve these assessments or contribute to the collection. Learn more about assessment design here.
