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 evolving ecosystems. 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 the characteristics of tropical rain forests and coral reefs.
- 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 an Evolving Ecosystems unit exam confirm understanding or identify any topics that require review.
Evolving Ecosystems Unit Objectives:
- Read about the Theory of Evolution.
- Learn about different types of natural selection.
- Explore terrestrial and freshwater ecosystems.
- Learn about the primary productivity of biomes.
- Read about the desert as well as coastlines and temperate grasslands.
1. Biomes: Desert, Tropical Rainforest, Savanna, Coral Reefs & More
Take a trip around the world and learn all about different biomes. Why can you only find certain plants and animals in specific places? What are the most fertile climates on Earth? Watch on to answer these and other questions.
2. Biomes: Tundra, Taiga, Temperate Grassland, and Coastlines
Take a trip with us in this lesson, starting in the Pacific Ocean, traveling across California through the Central Valley and up to the peaks of the Sierra Nevada mountains. We'll learn how oceans, elevation, and people can determine which types of biomes are found in different areas and check out the Earth's most massive and oldest organisms.
3. Primary Productivity of Biomes
Imagine a desert, a rainforest, and a lake. All of these areas are similar in that there are plants growing in them. These areas all vary because the amount of plant production is different based on the type of habitat. This lesson will explore the concept of primary productivity and how it varies by biomes. It will also discuss the most productive biomes and the biomes that produce the least biomass.
4. Ecological Succession: From Pioneer to Climax Communities
Just as people grow and change so, too, do ecosystems. Watch this lesson to learn about ecological succession from the beginning stages of development to a community's ultimate destination, or climax.
5. Succession in Freshwater and Terrestrial Ecosystems
The world's many freshwater and terrestrial ecosystems are constantly changing. This lesson will discuss how these ecosystems change over time and how they recover after disturbances occur.
6. Theories of Evolution: Lamarck vs. Darwin
We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.
7. Natural Selection & Adaptation: Definition, Theory & Examples
How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.
8. Natural Selection: Definition, Types & Examples
We'll take a look at the types of natural selection that can occur. From flying hamsters to moths, you'll start to grasp the different paths organisms can take as they respond to their changing environments over time.
