Ecology

It is easy to criticize society for not using renewable resources, but in reality, how difficult would this transition be? What processes and procedures would be involved? How would such a transition be made?

The purpose of this assignment is for you to consider what type of energy your neighborhood is currently powered by and what it would really take to convert this source to a renewable one. How much would it take to switch your community to a renewable resource and what would this mean for the environment?

For the assignment, complete the following:

  • Identify three primary types of energy that powers your home as well as all of the homes in your community. You may find this information on your community Web site or the Web sites of the local power companies. For example, your community may use electricity and solar panels.
  • Explain how the sources of energy you identified impact the environment. Consider the following:
    • Does the use of these types of energy resource have a negative impact on the environment in your area?
    • Does your community have nuclear waste to dispose of?
    • Has your community always used these three power sources? If so, how do you feel this has impacted the environment over time?
    • How much of an impact have these sources of energy had on local air and water quality?
  • Considering the current source(s) of power available, determine how much energy your house uses each month. You can find this information on your monthly energy bill.

    Calculate your annual usage for a year. Using this value, estimate the energy consumption for your community. The US Census Bureau is one resource you can use to estimate the number of households in your community.

  • You can use the following formulae for this calculation:

    (monthly energy usage) × (12 months per year) = (household energy usage per year);

    (yearly energy estimate for your house) × (estimated number of houses in your community) = (estimated yearly energy use for your community)

    The following is an example of the above calculation:

    52.8 kilowatt hours (kwh) per month × 12 months = 633.6 kwh;

    633.6 kwh × 200 houses in your community = 126,720 kwh

  • Recommend a realistic, renewable resource to power your community, using your calculated power needs. Consider the following sources: hydro-power, solar power, wind turbines, and geothermal energy.
    • Which source would be the best for your community?
    • Justify your choice based on the kind of resources that are available, how much power these alternative sources can produce, and your estimated energy demands for the community.
  • Having recommended an alternative power source, conclude by addressing the following:
    • How realistic is this alternative power source for your community?
    • How will people in your community respond to energy conversion? Will they support it or be against it? Give reasons.
    • How expensive would it be to convert to the alternative power source you recommended? How would this new source impact the environment?
    • What organisms would benefit most from this conversion?

Support your statements with appropriate examples and approximately 4–6 credible resources.

Write an 8–10-page paper in Word format. Apply APA standards to citation of sources.

Hybrid Car Research

A hybrid car is a motor vehicle that uses two or more different sources of power. In most hybrids, you will find an internal combustion engine in addition to an electrical motor. Depending on how the vehicle is driven and the availability of power, the car uses gasoline and battery power alternately.

In this assignment, you will research five different hybrid cars and evaluate their impact on the environment.

Using the readings for this module, the Argosy University online library resources, and the Internet, do the following:

  • Identify the top five most popular choices of hybrid cars. Analyze the advantages and disadvantages of each car’s technology, price, manufacturing, and impact on environment. Include the scientific principles involved in the technology.
  • Determine which type of car would work best for you and your family. Justify your decision based on your analysis of the five hybrid cars.
  • Explain the impact these cars will have on the United States’ economy. Consider the following issues in your analysis: consumer buying, sustainability, recycling, and fuel economy.
  • Evaluate the impact that hybrid-car technology has had or could have on the United States’ political relationships with oil-producing countries. Be sure to include an analysis of economic issues such as production, supply, and trade.
  • Describe how this technology will influence world politics. Include an analysis of economic issues such as production, supply, and trade.

Science tells us the truth about reality (or not)

write an academic essay that talk about “Science tells us the truth about reality (or not).”
My points are:I’ll stand against this statement, we should write about 3 points I have only one you can choice the other two points.– Science doesn’t tell us all the truth there is always story beyond what we see,Also there is always part of the truth we don’t know and the science couldn’t clarify that for us,– You can choice the other 2 points .. each points will be an individual paragraph.

Topic Selection Explanation Tips
For this course, you’ll be writing one final paper to highlight the multiplicity of information that you have learned. As part of your degree plan, you were asked to concentrate in several areas. When writing your paper, your paper must combine two disciplines. These disciplines may be in courses that you have taken as an elective or actual concentrations you’ve completed. Unless you have a compelling argument for the professor, your disciplines must come from the following list:

• Psychology
• Sociology
• Science
• Government
• History
• Computer Science
• Business

PLEASE SEE GUIDELINES AND SOURCE DOCUMENT ATTACHED.
• Literature
• Economics
• Criminal Justice

Physical Sciences

paper instructions

For these assignments you need to go to a popular science source and find an article about physical sciences or technology (physics, chemistry, geosciences, meteorology, astronomy; not biology or health). It should be a serious article. You need to read the article and possibly any related source material so that you understand what is being said and what the point of the article is. Then you need to give me approximately a one to two page (around 3-4 paragraphs, double-spaced) summary of the article in Microsoft Word format.

order-png-image
Your summary should include a reference citation for the article and any supplementary articles you may have used to help you understand the content of the article.
This is a set of small projects that will hopefully help you become familiar with numerous popular sources of science, become comfortable with reading and comprehending these sources, and practice at communicating the information gained to your peers. Hopefully by doing this assignment (and encouraging others to do the same) you will help elevate the general scientific literacy of society. And we need it!
You will be graded on grammar and spelling (0-2 points possible), your effective summary of the key points of the article (0-5 pts), your writing style and citation reference (0-1), and your choice of an appropriate article and source of solid scientific information (0-2 pts).
Examples of good sources are
-The New York Times (which has a science section every Tuesday) available online at www.nytimes.com
-Science News (a brief but excellent newsletter available in many libraries and on newstands)
-Popular Science, Scientific American, Discover, New Scientist, National Geographic, or some similar magazine
-Do NOT use ScienceDaily.com as its articles tend to be superficial and misleading, and that could lead to a lower score for you.
-NEVER use the Yahoo science pages or similar fluff. They are too frequently low quality.

Scientific Cannons and Pseudoscience Activity

Part 1: Cannons of Science

Review the four Cannons of Science by defining the terms using your textbook.

Parsimony:

Determinism:

Testability:

Empiricism:

 

Part 2: Distinguishing Science from Pseudoscience

Pseudoscience is sometimes passed off as real science in the news media. People want consumers to buy their products and they may use “science” to entice you to buy their products. Oftentimes, the “science” they claim backs their product isn’t science at all. It may include components that are scientific in nature (e.g., testability), but the product or service may still lack scientific support. This kind of пїЅscienceпїЅ is called pseudoscience.

As an example of a pseudoscientific claim, take healing rocks. At many new age stores, there are rocks that are purported to help heal illness or alleviate pain. The idea that rocks can heal you includes two cannons of science; testability and empiricism. That is, one could test the hypothesis that rocks heal (testability) by systematically observing (empiricism) people who are ill use the rocks compared to people who are ill who do not use the rocks. Further, the claim is deterministic because it suggests that the rocks cause people to feel better. In this sense, it is a scientific claim. However, it is still pseudoscience (or junk science) because it lacks parsimony (it is not the simplest explanation, and in fact, there are quite a few alternative explanations that could explain why people feel better after they buy healing rocks), and it lacks scientific support (there are no studies linking rocks to healing).

Instructions: Below there a number of claims that are scientific or not so scientific (pseudo-science). Read each claim and decide:

(1) Is this science or pseudoscience/junk science?

(2) Use at least one of the four cannons of science to justify or support your decision.

(3) What additional evidence or information would help you make an affirmative decision about whether the claim is science or pseudoscience/junk science?

 

A. Parents who are afraid that their children are developing slowly are happy to hear about brain gym; a new program based on kinesiology (movement therapy) that can bring about dramatic improvements in areas such as: concentration and focus, memory, academics, physical coordination, relationships, self-responsibility, organizational skills and attitude. The basic idea is that movement can massage brain regions to improve circulation and thinking skills. The studies that support brain gym show that students who join the program seem to do better over time. In other words, researchers observed children and found that they had improved.

B. Climate change refers to any significant change in measures of climate lasting for an extended period. As through much of its history, the Earth’s climate is changing. Right now it is getting warmer. Most of the warming in recent decades is very likely the result of human activities (IPCC, 2007). The National Oceanic and Atmospheric Administration’s (NOAA) State of the Climate Report and the National Aeronautics and Space Administration’s (NASA) Surface Temperature Analysis indicate the average temperature of the Earth’s surface has increased by about 1.2 to 1.4ВєF since 1900. Other aspects of the climate are also changing such as precipitation patterns and storminess. The Earth does go through natural cycles of warming and cooling, caused by factors such as changes in the sun or volcanic activity. This has been closely examined, and the warming we have seen in the past 50 years cannot be explained by natural factors alone. The warming we are observing is consistent with the warming properties of carbon dioxide and other heat-trapping gases that we are adding to the atmosphere.

 

C. Juicing is a natural way to stay healthy, look young, say trim and feel great. Juice has natural healing power and active enzymes that allow the vital energy in the body to be shifted from digestion to other body functions such as repair or rejuvenation. Juicing flushes the body of toxins and it works because of the high concentration of vitamins and minerals in fresh fruit. The enzymes in fruit are the critical agent that helps your body and mind feel great!

 

D. Ectoplasm is understood to be outside the range of normal everyday experience. It is the name given to the material that is left over when a medium communicates with another dimension. Ectoplasm is an elusive substance that exudes from the body of a medium. It is seemingly life-like and can materialize into the limbs or the entire bodies of other beings. It may form a solid or vapor and appears to be milky white in color. At times it has been described as translucent. When it is exposed to light, it disappears.
