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 Statements:
- Assume that reactions with any gas production are conducted in a closed system.
- Assessment Boundary:
- Distinguishing mass and weight is not expected in state assessment.
