Learning Objective:  Describe HOW and WHY global human population and the populations of different geographic regions (or countries) have changed over the past 10,000 (2,000) years.

Knowledge:

Sketch a graph of human population changes over the past 10,000 (2,000) years.

Comprehension:

There are many factors that affect the rate of population growth.  Choose one of these factors and describe how this factor has changed over the past 10,000 years.  In addition, discuss how political, social, economic, or technological factors have influenced this change.

 Application:

What would happen to human population growth if:

  • birth rate increased and death rate increased?
  • Number of children per mother decreased and death rate decreased?
  •  Additional scenarios

**This could be written as a multiple choice question**

If a population experienced an increase in birth rate and a decrease in death rate,

A.     it would experience positive population growth rate

B.     there would be a zero population growth rate

C.     there would be a negative population growth rate.

Analysis:

Looking at Hans Rosling’s Gap Minder (this would be more of a formative assessment done in-class)

  • demonstrate how to use the program and show a few examples of relationships
  • assign each group a different relationship to examine and share with the class

 

Looking at the graph of age distribution of Japan’s Population,

  • Is population growth positive, stable, or negative?
  • What affect does life expectancy have on Japan’s population?
  • What affect does birth rate have on Japan’s population?

Learning Objective:  Recognize the consequences that occur when a population reaches carrying capacity. Evaluate if the human population is reaching Earth’s carrying capacity and the impacts of overpopulation.

Comprehension:

Sketch a graph of what happens to a population AFTER it experiences exponential growth and reaches the carrying capacity. 

Application:

What would happen if the carrying capacity of a population changes (increases or decreases)?

Analysis/Evaluation:

What are some pieces of data that support this statement?

  • The human population is reaching the Earth’s Carrying Capacity.
  • The human population is far from the Earth’s Carrying Capacity.

 

Learning Objective:  Describe the connections between organisms in a food web and the movement of energy and chemicals through living and nonliving systems (carbon cycle and biological magnification).

**From A Vision for Change:  “Living Systems are connected & interacting.”**

Comprehension:

What is the primary source of energy in biological systems?

Using your understanding of energy transfer in biological systems and keeping in mind a goal of striving toward energy efficiency and decreasing use of energy as the basis of your argument, argue for eating a vegetarian diet or for decreasing the amount of meat you consume.

 

Give the food web diagram below, what would happen if a non-biodegradable substance were introduced into the water supply (such as mercury)?

 

What role do humans play in the carbon cycle?

 

One of the organisms on the endangered species list is a

Salmon, chinook (CA coastal) ( Oncorhynchus tshawytscha)

Fly, Delhi Sands flower-loving ( Rhaphiomidas terminatus abdominalis)

 

Using scientific evidence, respond to this statement:

-       The climate's changed before, the changes happening right now are just part of the natural cycle.

-       The past winter was really cold with a lot of snow across the US.  The climate is actually cooling, not warming.

-       So what? – the temperature is going up be a few degrees.  It’s not that bad.

 

Learning Objective:  Analyze your ecological footprint and determine where you can decrease your impact on the Earth’s resources.

 

Comprehension:

What contributes to an ecological footprint?

What contributes to a carbon footprint?

What contributes to a water footprint?

 

 

Learning Objective:  Describe ways that humans (or you) can minimize their impact on the earth and strive for sustainability.
