Examine 48 hour culture of yeast cell population growth. Approximate number of individuals within a given grid on the slide.
Examine a graph of the demographic transition model.
List and discuss key elements which are found in each of the 5 phases of the model.
List and discuss the transition from each phase to the next, and what predictions regarding population growth can be obtained from each phase.
Discuss migration, the effects of immigration and emigration on the rate of population growth.
Work with the formula to determine net immigration rate from the number of immigrants per year and the population.
Work through example problem in text.
View age-structure diagrams and analyze the information which can be used to predict population growth.
Discuss the global population will probably not reach the anticipated 10 billion.
Define and outline total fertility rate.
Define and outline replacement level fertility, and analyze the numbers from different countries.
Discuss total replacement rate
Discuss life expectancy numbers and how they are used to predict population expansion.
Analyze infant and child mortality rate numbers and why they may be different in different countries, or in different areas of one country.
Outline and discuss aging and disease as a regulating factor in population studies. l

Joshua was very active in class participation today
Discuss the Malthus theory regarding population growth and food supply, and how they appear on a graph.
Discuss if humans have reached the carrying capacity, and what may occur if the have.
Present the argument that increased populations will provide an increasing amount of innovation, which will alter the carrying capacity through creativity and technological advances.
Present factors, birth rate, death rate, fertility rate, migration, and life expectancy, which will influence population growth.
Introduce the crude birth rate, the global population rate for both a nation and the globe, as well as a formula for determining doubling time for populations.
Lab exercise to determine a calculated population of species using a formula which includes captured and marked and captured only organisms.
discussion of factors which influence species richness.These involve colonization, speciation, and extinction. The processes are influenced by latitude, time, habitat size, and distance from the source of colonizing species.
Primary succession from bare rock to climax community is discussed and viewed using diagrams and photos. The part played by plants and other organisms involved in the succession are outlined and discussed.
Secondary succession from soil to climax community is examined next, along with the plants and animal organisms involved in this succession.

Lesson Comments
Joshua read the module as requested and was involved in the discussions
Reviews the previous symbiotic relationships and then discuss commensalism.
Use examples to define and explain what a keystone species represents and the role of the keystone predator in clearing spaces for other species to inhabit.
Day one of the development of a yeast population using grape juice as a source of food. Counts will be taken over a period of 8 days and the population numbers graphed.
Classwork involves a discussion of predators and predation, parasites and parasitism, and mutualism amoung organism.
Diagrams and photos are examined, along with methods used by organisms to prevent predation.
Review the competitive exclusion principle.
Discuss resource partitioning in which 2 species divide a resource based on differences in morphology and behavior, in order to lower competition.
List and discuss the 3 types of resource partitioning.
Discuss predation as it involves community ecology. Define parasitoids, use examples.
Define and discuss behavioral, morphological and chemical methods used by organisms to lessen predation.
