Case Study: Middle School Earth Science Lesson Adaptation
Focal Science Practice:
Developing and using models
Planning and carrying out investigations
Analyzing and interpreting data
Using mathematical and computational thinking
Engaging in argument from evidence
Obtaining, evaluating and communicating information
Ms. Meyer’s fifth grade class is in the middle of a unit on matter. In this lesson, students will investigate what happens to a substance when it is mixed with another substance. During this investigation, students will use mathematical skills (i.e., measuring, comparing, estimating) or concepts (i.e., ratios) to make sense of their results.
Related NGSS Performance Expectation:
5-PS1-2. 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.
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.
