Assignment 1: Applications of the Scientific Method Due Week 4 and worth 160 points The scientific method is useful in problem solving and decisionmaking in a wide variety of fields. In this assignment, you will demonstrate how to use the scientific method to make decisions and solve problems in your field of study or everyday life. Identify a specific problem often faced in your field of study or everyday life. Research your problem and assess your data / research. Examples of such problems could be: 1.Business 1.Developing a new product that is superior to competitor’s brands; or 2.Establishing a price for a new product using the law of supply and demand; 2.Information Systems and Technology 1.The use of personal electronic devices for work purpose, or 2.Determining in the most cost-effective computer for your business; 3.Criminal Justice 1.The reliability of eyewitness testimony, or 2.Determining what evidence reveals to you about a crime; 4.Everyday Life 1.Selecting a particular brand of detergent, or 2.Determining the most cost-efficient transportation / route for your commute. Write a three to five (3-5) page paper in which you:
1.Explain the scientific method and describe the overall manner in which you would apply it in your field of study or everyday life. 2.Propose one (1) testable hypothesis to explain / solve the problem you have selected. State the expected outcomes of your actions and include criteria for determining whether or not these actions would succeed. Note: Your hypothesis should be stated very precisely. 3.Describe the main actions that you intend to put into place to test the hypothesis that you proposed in Question 2. Describe the way in which you would evaluate the success of your program. Include the results that you would deem as a success and the results that would be considered a failure. 4.Discuss the wisdom behind the strategy you would use to test the hypothesis from Question 3, and describe the additional steps you might take, depending on the results of your test. Note: These additional steps might be to revise your original hypothesis (if the results were unsatisfactory) or to propose new hypotheses. The goal is to continuously improve your understanding of the factors influencing your outcomes, to be able to achieve greater results over time. 5.Use at least two (2) quality resources / references in this assignment.

Assignment 2: Global Warming: Cause and Mitigation Due Week 9 and worth 160 points Among the most controversial topics in physical science, global warming has received a great deal of attention during the past decade. Given its great impacts on both humans and the environment, lawmakers and scientists must weigh heavily the information that they are presented. Explore this debate in more detail by evaluating both the scientific basis of this phenomenon and the human role in global warming. Write a three to five (3-5) page paper in which you: 1. Compare and contrast natural versus anthropogenic climate changes. Include specific examples of each. 2. Take a position as to whether or not global warming is taking place. Provide three (3) lines of evidence to support your position. 3. Assess two (2) current mitigation strategies for global warming, such as carbon sequestration, carbon taxing, clean coal technology, higher fuel efficiency standards, and so on. Include a discussion on the effectiveness of this mitigation strategy, as well as its potential costs and policy implications. 4. Speculate what policy changes you would propose to help stabilize global climate and which business sectors or nations would be held to more strict standards if you implement your proposed policies. 5. Use at least four (4) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources. The body of the paper must have in-text citations that
correspond to the references. Integrate all sources into your paper using proper techniques of quoting, paraphrasing and summarizing, along with proper use of in-text citations to credit your sources Your report must follow these formatting requirements: • Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format.
