Kootenai River Bedload This video from the USGS shows the motion (saltation) of sediment in the Kootenai River, ID. This slow motion video shows the process of saltation. The Colorado River: Running Near Empty This video follows the course of the Colorado River and shows the impact of water diversion on the river. In addition, the activity models the transport of pollutants at the Earth's surface.

Using a water spray bottle, they examine how runoff from precipitation moves in the landscape forming streams and lakes. In this activity, students create a simple model of a mountainous landscape on the Earth's surface. PowerPoint setup presentation PowerPointĭesktop Watershed.

Included is a PowerPoint presentation that can be used to help students set up their experiment. The lesson advances students’ qualitative understanding of how rivers shape the Earth’s surface while explicitly providing opportunities to develop their science practices such as observation, modeling and experimentation. Students will recreate a model of a river system in a table top experiment.

Template for card sort activity PDF PowerPoint Document.

Students experience a model of a stream table to form an understanding of the different variables that can shape a river and its surroundings. A vocabulary card sort introduces the geologic features they may observe in a stream table lab.

Student Activity Sheet PDF Word Document.

They will be asked to make a prediction as to which type of sediment will be on the bottom of the tube when the tube is shaken. Students will be given sediment tubes containing gravel, sand and silt. The real life application of which side of the river should you build your house on stimulates students’ interest in the erosion and deposition of sediment that may modify the landscape. The results of this probe can be used to guide instruction to address misconceptions and gaps in understanding. In this lesson, the teacher administers an assessment probe to activate students’ prior knowledge about how moving water (rivers) change the surface of the Earth.

Click to download a primer for teachers on mechanical and physical weathering of rocks and minerals. Click to download an overview of the Rivers Instructional Case. Through hands on activities, students will gain an understanding of how water velocity (gradient) may affect the shape of the river and observe the surface features that result. Through this instructional case, students will develop an understanding of the how rivers transport (erosion) and deposit sediment and evolve over time. The rivers instructional case advance students’ qualitative understanding of how rivers modify and shape the Earth’s surface. The Rivers Instructional Case (IC) consists of four lessons that can be used to supplement a broader unit on erosion. 2 Click here to view the second part about erosion, sediment transport and deposition and flooding. 1 Click here to view the first part about stream discharge and drainage networks.

Introductory material on the agents of erosion is available in the Erosion unit. This is a unit about erosion and deposition of sediments associated with streams. This unit contains resources about streams, how they modify the landscape, and flood hazards.
