The key to success in teaching a unit on ecology is to provide good instruction followed by a good review exercise.
This PowerPoint consists of 69 slides of questions and answers and provides an excellent review for the chapter test. I use this review PowerPoint after completing the material in this unit: Population Ecology PPT and Notes.
This is NOT a teaching PowerPoint. It is strictly for review purposes. Each slide has one question followed by one answer.
The questions are of varying difficulty levels. Many of the questions are basic and concrete in nature, but many of the questions involve critical thinking and problem solving skills.
This set of questions is perfect for any type of game format. Students can form groups and compete with one another during the review exercise. The review PowerPoint can also be used in a computer lab with each student reviewing independently and silently.
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 review PowerPoint is appropriate for any biology or life science class with students in grades 7 - 12.
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.
