Topic: Population Ecology
56-slide PowerPoint with Notes for Teacher and Student
Ecology is one of the "must-teach" topics for any biology or life science class. The ecological inter-relationships that occur in nature are fundamental to an understanding of our world and how life interacts with the physical environment as well as with other living organisms. Ecology topics, such as global warming, ozone destruction, greenhouse gases, and habitat destruction, dominate the news. We must make sure that our students are knowledgeable in these topics so they can be informed decision makers in the future.
There is so much material to teach in a unit on Ecology that it can be overwhelming. I have divided the information into 6 separate units of instruction:
1. Introduction to Ecology
2. Population Ecology
3. Community Ecology
4. Ecosystems and the Biosphere Part 1: Energy Flow and the Recycling of Matter
5. Ecosystems and the Biosphere Part 2: Biomes of the World
6. Humans and the Environment
Please Note: This product is just for the second topic of instruction: Population Ecology
If you have never taught a lesson using a Powerpoint presentation, you have to give it a try! My students always prefer this to a traditional lecture. The use of eye-catching photos and diagrams rarely fails to stimulate a lively class discussion.
This product is also included in a complete unit plan bundle that includes everything you need to complete a unit on this topic: Population Ecology Complete Unit Plan.
This PowerPoint is on "Population Ecology". It consists of 56 slides that are colorful, informative and visually stimulating. Pictures and diagrams are included that will greatly enhance your instruction to your students. This product also includes a set of notes for the teacher (8 pages) and a set of notes for the student (11 pages). Graphics, diagrams, clip art, and photographs were chosen to capture the attention of the student as the lesson is being taught.
Topics covered in this lesson are:
1. Characteristics of Populations: Definition of population, geographic distribution, density, dispersion, growth rate, and age structure.
2. Types of Dispersion: Clumped, even, and random, definitions and examples are given.
3. Population Dynamics: Birth rate, death rate, life expectancy.
4. Patterns of mortality: Survivorship Curves, the three types are defined and explained, examples given.
5. Life Histories: Big-bang reproduction and repeated reproduction
6. Population Growth: Growth rate, factors that determine the size of a population, migration, density, exponential growth, carrying capacity, limits to population growth, graphs of different types of population growth, logistic growth, assumptions of the exponential model and the logistic model.
7. Limits to Growth: Limiting factors, examples of limiting factors, density-dependent factors, competition, predation, parasitism, disease, territoriality, density independent factors.
8. Human Population Growth: The history of human population growth, current human population growth, demographic transition, age-structure diagrams.
This PowerPoint was written with a typical biology I class in mind. It can easily be edited to meet your needs.
Also included is a set of notes to accompany this PowerPoint. It includes a complete set of notes for the teacher, and an outline of the notes for the students. Students will use the outline as the PowerPoint is being presented and will fill in the notes as the lesson is being taught. I always include both the Word document and a pdf of the notes.
Please let me know if you have any questions. Thanks for looking.
