About This Chapter
Who's it for?
This unit of our AP Environmental Science Homeschool course will benefit any student who is trying to learn about the flow of running water. There is no faster or easier way to learn about environmental science. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about turbulent and laminar streamflows.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need an environmental science curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and a Running Water unit exam confirm understanding or identify any topics that require review.
Running Water Unit Objectives:
- Define stream base levels and explain their effect on erosion.
- Read about landform diagrams.
- Explore the different types of alluvial channels.
- Discuss the formation of stream valleys.
- Explore the characteristics of drainage basins.
1. Drainage Basins: Definition & Characteristics
Do you know where the water in your area flows? In this lesson, we will explore the system of drainage basins and how they help develop river systems. We will also investigate some extreme examples of drainage basins.
2. Laminar & Turbulent Streamflows
Streams come in many different shapes and sizes. They can also vary in speed and direction of flow. In this lesson, we will explore two different ways that water can flow through a stream.
3. Effect of Erosion and Deposition on Landforms
Landforms are constantly being broken down and reformed by the processes of weathering, erosion, and deposition. In this lesson, we explore chemical and physical weathering and how the face of the earth gets changed.
4. How a Landform Diagram Describes the Geological Progression of a Landscape
This lesson describes what a landform diagram is. We'll also discuss some basic laws of geology that can help scientists deduce both the order of events that create a landform and the geologic events that occur after a landform's formation.
5. The Formation of Stream Valleys
Running water is very powerful and has the ability to change the land around it. In this lesson, we will explore the creation of stream valleys and how they are shaped by the water that runs through them.
6. Base Level of a Stream: Definition & Effect on Erosion
Water stops flowing when it reaches its lowest level; this is called the base level. Learn about the base level of a stream, how it affects erosion, and some examples of local base levels, including lakes, dams and waterfalls.
7. Bedrock Channels: Formation & Process
Bedrock channels are eroded paths cut through solid rock foundations known as bedrock. Learn about bedrock channels and the processes that form them, including abrasion and plucking.
8. Alluvial Channels: Definition & Types
An alluvial channel is a water channel made up of loose sediments called alluvium. Learn about the types of alluvial channels, meandering channels and braided channels, and the characteristics that make them unique in this lesson.
