4FN14 – Science – Deposition and Erosion

How do FreeNode lessons work?

FreeNodes are instructor-led schooling lessons with a unique approach, granting you the freedom to independently teach using a personalized lesson plan. This autonomy enables you to tailor your lessons to suit students’ individual needs, learning styles, and interests.

To use a FreeNode, read the provided class outline & follow the formatting provided for each class. Make sure to touch on the Theocratic Connection in each class. Follow the outline closely so it is aligned with our main at-home curriculum.

How Do I Use the FreeNode?

Read this lesson plan before class to familiarize yourself with the ideas and concepts you’ll be teaching the students. You may print this page out if you need to use it as a reference point during live classes.

This lesson is a guide, but feel free to expand on the content or decrease/increase what you teach depending on the learning levels of the students in your class or the amount of time you have to cover the material.

Can I show videos in FN classes?

Yes, feel free to include additional material to supplement the class lesson material. Videos, Physical Objects, Games, Activities, etc. are okay to share in live classes.

Videos should have no advertisements or logos and should be viewed by you before showing them to the students to ensure no offensive or questionable content is included.

The video should make up only 1-3 minutes of the live class and should not take the place of instructor-led instruction. Videos should be supplementary only.

How do bookmarks work?

Bookmarks help you keep track of lessons you’re going to teach in future live classes. The bookmarks you see are for all your bookmarked lessons across all grades.

You can bookmark a lesson by visiting the lesson you want to bookmark and clicking the “bookmark” button in the bookmark section.

You can remove a single bookmark by visiting a lesson you’ve bookmarked and clicking the “bookmark” button again to unbookmark it.

You can clear all of your bookmarks by clicking the “clear all bookmarks” button. Be careful, this will erase all of your bookmarks.

Class Lesson Plan

Objectives:

Understand the processes of erosion and deposition.
Identify the agents of erosion: water, wind, and ice.
Explore the factors influencing erosion, including types of soil, size of sediments, and the force of water and wind.
Recognize the importance of preventing soil erosion and the role of plants and agricultural practices.

Materials:

Whiteboard/Chalkboard and markers/chalk
Visual aids (images or diagrams of erosion, deposition, examples of plants with strong root systems)

Introduction (2 minutes):

Introduce the term “erosion” as the process where rocks and minerals, after being weathered, are carried away by natural forces. Discuss the importance of understanding erosion in shaping the land.

Theocratic Connections:

N/A

Activity 1 – Water Erodes (5 minutes):

Explain that water primarily causes erosion by moving and transporting sediments.
Discuss how rain washes sediments into rivers and streams, and ocean waves erode rocks and deposit sediments on the shore. Emphasize the role of water in reshaping the land over time. Use examples such as the Grand Canyon being shaped by erosion from the Colorado river.

Activity 2 – Wind Erodes (5 minutes):

Describe wind erosion as the process where small particles of rock, sand, and soil are picked up by the wind and transported.

Explain how the wind contributes to weathering by blowing sand against rocks, wearing them down over time. Use examples such as the Munga-Thirri National Park being shaped by wind erosion over time.

Activity 3 – What Affects Erosion? (5 minutes):

Explore factors influencing erosion, including types of soil, size of sediments, and the force of water and wind. Discuss how sandy soil erodes more easily than moist or hard-packed clay soil.
Explain that erosion is affected by the size of sediments, and the strength of water and wind.

Activity 4 – Preventing Soil Erosion (5 minutes):

Discuss the significance of preventing soil erosion for maintaining topsoil and supporting plant life.
Explain how plants, especially those with strong root systems, can prevent erosion.
Introduce agricultural methods like strip farming as preventive measures.

Activity 5 – What is Deposition? (5 minutes):

Define deposition as the process of sediment being placed in a new location by wind or water.
Discuss examples of deposition, such as sediments along riverbanks and ocean waves depositing sediments on the ocean floor.

Conclusion (3 minutes):

Summarize the key points: erosion, deposition, factors affecting erosion, and preventive measures.
Emphasize the importance of responsible land use and agricultural practices to prevent soil erosion.

Assessment:

Informally assess student participation during class discussions and activities.
