Kit Lesson 10: Rushing Rivers: Exploring Flow (PT)
Flowing water has the power to alter the shape of the land. Scientists define the flow of a stream as the amount of water that passes a given point in the channel in a given amount of time, the greater the flow, the greater the material transport. Converging streams (Lesson 9) have greater flow than either of their source streams because the amount of water in the channel suddenly increases which eventually causes increased erosion and load. Rivers carry the largest loads, smaller streams (Lesson 4) can carry a load but the greater the water present, the greater the stream’s erosive power. Majority of earth materials eroded and transported are carried during short periods of flooding. Sudden rainstorms cause high runoff and increased flow downstream. When water recedes from floodwater sediment is carried and the sediment left behind creates a floodplain.
1. Claims, Evidence, & Reasoning Chart: State the claim: fast and slow flowing water create different results. Students will then use evidence found in the explain and supported their knowledge of the claim.
