Ch 16: Organism Interactions Lesson Plans

About This Chapter

The Organism Interactions chapter of this course is designed to help you plan and teach the students in your classroom about terms such as symbiotic relationships, colonization and migration. The video lessons, quizzes and transcripts can easily be adapted to provide your lesson plans with engaging and dynamic educational content. Make planning your course easier by using our syllabus as a guide.

Weekly Syllabus

Below is a sample breakdown of the Organism Interactions chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.

Day Topics Key Terms and Concepts Covered
Monday Interspecific Competition, Competitive Exclusion and Niche Differentiation;
Predator / Prey Interactions, Camouflage, Mimicry and Warning Coloration;
Symbiotic Relationships: Mutualism, Commensalism and Parasitism
Competition between various species in an ecosystem, and the coexistence of different species;
Defense strategies of prey, and offensive tactics of predators;
A look at parasitism and commensalism between species
Tuesday Populations: Density, Survivorship and Life Histories;

Interspecific Competition, Competitive Exclusion & Niche Differentiation

1. Interspecific Competition, Competitive Exclusion & Niche Differentiation

What happens when two similar species that consume the same resources occupy the same space? Interspecific competition, that's what! Watch our video lesson to learn about the outcomes of this ecological battle.

Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

2. Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

You probably know that skunks can be quite stinky, bees sting and monarch butterflies are pretty, but do you know why? This lesson will introduce you to the reasons why some animals look or act the way they do and how these things relate to the predator/prey relationship.

Symbiotic Relationships: Mutualism, Commensalism & Parasitism

3. Symbiotic Relationships: Mutualism, Commensalism & Parasitism

If your cat or dog has ever had fleas, you've witnessed symbiosis in action. In this lesson, learn the many types of symbiosis in biology, and how these relationships can have a positive, negative, or neutral effect on the individual species.

Populations: Density, Survivorship and Life Histories

4. Populations: Density, Survivorship and Life Histories

Have you ever wondered how biologists determine the populations of animals in a particular geographic area? Watch this video lesson to find out, and discover how scientists look at the survivorship and life histories of many different species.

Carrying Capacity, Migration & Dispersion

5. Carrying Capacity, Migration & Dispersion

Have you ever wondered why some types of birds fly south in the winter or why some animals form territories? Watch this video to learn about a species' maximum growth capabilities, the way its members group themselves and why they might migrate to new locations every year.

Dispersal, Colonization, and Island Biogeography

6. Dispersal, Colonization, and Island Biogeography

Have you ever gone in your backyard and discovered a wild raspberry bush that has never been there before? How did it get there? Why is there only one bush year after year? In this lesson, you'll study how plant and animal species colonize in new areas through dispersal and immigration and how some species thrive in a new area while others fail.

Conservation Biology, Habitat Fragmentation, and Metapopulations

7. Conservation Biology, Habitat Fragmentation, and Metapopulations

It's becoming harder to conserve large, unbroken tracts of wilderness. Is there another way for conservation biologists to ensure the survival of a species? In this lesson, you'll learn about habitat fragmentation and metapopulations.

How Introduced and Invasive Species Alter Ecological Balance

8. How Introduced and Invasive Species Alter Ecological Balance

What happens to your block when a new neighbor moves in? Something changes, right? Now think about that on an ecological scale: what happens to an environment when a new SPECIES moves in?
