CA Science Standards
5a. Students know some changes in the earth are due to slow processes, such as erosion, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes.
5c. Students know moving water erodes landforms, reshaping the land by taking it away from some places and depositing it as pebbles, sand, silt, and mud in other places (weathering, transport, and deposition).
6c. Formulate and justify predictions based on cause-and-effect relationships.
6d. Conduct multiple trials to test a prediction and draw conclusions about the relationships between predictions and results.


6f. Follow a set of written instructions for a scientific investigation.
