4 Great Intro to Weathering and Erosion

The questions are great for discussion after viewing the clip.

Description

This two-minute video from NBC Nightly News illustrates the role of ocean waves in the geoscience processes of erosion, deposition and weathering.  This clip can be used as an introduction to MS-ESS2-2 which focuses on how these processes have changed Earth's surface at varying time and spatial scales.

The specific phenomenon reported on in this piece could stimulate the following introductory questions: 

1. What geoscience processes are at work in this video?

2. Have the processes accelerated over the past few decades?

3. What factors may be responsible for the acceleration?

4. What political and economic issues could be affected by the processes?

5. What can be done to mitigate the effects of the processes?

As a reminder, teachers may want to preview the link to check if any viewers have left inappropriate comments; the video clip itself is appropriate for all audiences.

Performance Expectations

MS-ESS2-2 Construct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying time and spatial scales.

Clarification Statement: Emphasis is on how processes change Earth’s surface at time and spatial scales that can be large (such as slow plate motions or the uplift of large mountain ranges) or small (such as rapid landslides or microscopic geochemical reactions), and how many geoscience processes (such as earthquakes, volcanoes, and meteor impacts) usually behave gradually but are punctuated by catastrophic events. Examples of geoscience processes include surface weathering and deposition by the movements of water, ice, and wind. Emphasis is on geoscience processes that shape local geographic features, where appropriate.

Assessment Boundary: none

This resource was not designed to build towards this performance expectation, but can be used to build towards it using the suggestions provided below.

Comments about Including the Performance Expectation
This video provides an attention-grabbing introduction to the Performance Expectation and should spur students to further investigate the role of erosion in changing Earth’s surface. Although the clip does not provide scientific evidence supporting the role of ocean waves on land erosion, it does serve as dramatic anecdotal evidence for this phenomenon.

Science and Engineering Practices

This resource was not designed to build towards this science and engineering practice, but can be used to build towards it using the suggestions provided below.

Comments about Including the Science and Engineering Practice
Several scenes in the clip should give rise to questions in the middle school classroom. For example, students may wonder how ocean waves contain enough energy to bring down large tracts of land. They may want to seek additional information on the speed of such erosions and whether this situation is typical or out of the norm. Students may additionally want to investigate whether this phenomenon is confined to California or whether it is occurring elsewhere. Finally, they may wonder whether there is a connection between erosion, weather phenomena and climate change.

Disciplinary Core Ideas

This resource appears to be designed to build towards this disciplinary core idea, though the resource developer has not explicitly stated so.

Comments about Including the Disciplinary Core Idea
This clip from NBC News acts as a hook to spur student interest in the geoscience processes of water movement and erosion. The video highlights the erosive power of ocean waves and raises the issue of how humans must take this energy into account when planning land use. Students should be made aware that such sudden changes in topography are rare; however, even incremental changes can result in dramatic surface transformations over the long run.

Crosscutting Concepts

This resource was not designed to build towards this crosscutting concept, but can be used to build towards it using the suggestions provided below.

Comments about Including the Crosscutting Concept
As students view this phenomenon, they should consider the cause and effect relationships evident within the clip. Students should be encouraged to look beyond the obvious relationship between the energy found in ocean waves and erosion; teachers might consider prodding students in the direction of how climate change may play a role in this process.
