Critical Attributes Strategy


1.  What is critical attributes strategy?
             
The critical attributes strategy is a strategy that concentrates on spreading procedural knowledge.  It defines the most important concepts and ideas of a specific topic.  These concepts and ideas are what help people become effective citizens.

2.  Develop a critical attirbutes list of the concepts in your current event topic.  List content, definitions, examples.  What are some non critical attributes?

Content
·         Global Warming Effects and Solution

Definitions
Atmosphere: The mixture of gases surrounding the Earth. The Earth's atmosphere consists of about 79.1% nitrogen, 20.9% oxygen, 0.036% carbon dioxide and trace amounts of other gases. The atmosphere can be divided into a number of layers according to its mixing or chemical characteristics, generally determined by temperature.

Climate: The average weather a particular region and time period.

Ecosystem: The complex of a community of organisms and the community's environment functioning as an ecological unit.

Environment: The complex of physical, chemical, and biotic factors (such as climate, soil, and living things) that act upon an organism (a living thing) or an ecological community (a collection of living things) and ultimately determine its form and survival.

Greenhouse Effect: The effect produced as greenhouse gases allow incoming solar radiation to pass through the Earth's atmosphere, but prevent most of the outgoing infrared radiation from the surface and lower atmosphere from escaping into outer space. This process occurs naturally and has kept the Earth's temperature about 60 degrees Fahrenheit warmer than it would otherwise be. Current life on Earth could not be sustained without the natural greenhouse effect.

Greenhouse Gas: Any gas that absorbs infra-red radiation in the atmosphere.

Critical Attribute Examples
·         About 20% of CO2 emitted into the atmosphere comes from the gasoline burned in motor vehicle engines. The vast majority of emitted CO2 is a result of fossil fuel burning in power plants for electricity generation.
·         Roughly 75% of the annual increase in atmospheric CO2 is due solely to the burning of fossil fuels
·         Cars amount to three-quarters of all transportation emissions. At the current rate, the world will be driven on by more than a billion cars in 2030 and a billion more by 2050.
·         The United States represents less than 5% of the world’s population, yet Americans account for 25% of the world’s commercial energy consumption and 22% of the world’s industrial emissions of CO2
Non Critical Attributes
·         Solving global warming will devastate our economy.
·         Measurements from satellites show that the earth is not warming.

3.  What is your level of passion in this topic and/or your detached objectivity?

This is something that we as a group feel is affecting our community.  It is something that has caught our interest and we are intrigued to learn more.  Our passion for Global Warming is slowing increasing as we learn more facts.

4.  Do you think a level of passion gets you more fired up to want to learn it? 

I think the level of passion does indeed get us more fired up to learn more about Global Warming.  In my experience, you need to have a desire to truly learn more about a topic fully. 


5.  How can you avoid a discussion in your classroom from becoming a debate

When having a discussion on Global Warming, it can become controversial.  It needs to be stated from the beginning that there are different opinions to every topic and everyone is entitled to their opinion.  The facts need to be presented in a mature manner with questions or opinions offered without negative feelings in return.

6.  Take the four challenges, and develop four questions you would ask to facilitate a discussion in our class on Tuesday on your topic.
1.      What is the evidence that temperature and carbon dioxide concentrations are correlated?
2.      What is the evidence that the use of fossil fuels, which produce carbon dioxide, is causing climate change?
3.      What are some the consequences or impacts to the environment and human society caused by Global Warming?
4.      How often do you think about the environment? Is it enough? Why/not?
