Assignment 1: Applications of the Scientific Method
Due Week 4 and worth 160 points

 

The scientific method is useful in problem solving and decision-making 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. Note: Wikipedia and personal blogs do not qualify as quality resources.

 

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. Check with your professor for any additional instructions.
  • Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

 

The specific course learning outcomes associated with this assignment are:

 

  • Apply concepts in physical sciences to evaluate current trends and issues in the modern world.
  • Describe the physical processes influencing climate and weather.
  • Use technology and information resources to research issues in physical sciences.
  • Write clearly and concisely about physical sciences using proper writing mechanics

Human Impacts on the Sustainability of Groundwater

/in /by

In this lab, you will observe the time progression of industrialization and human development to help you write up a scientific paper that centers on the following:

  • If current human development does not change, will groundwater sustainability be affected? Explain your observations.

Human Impacts on the Sustainability of Groundwater

Sustainability is based on a simple principle: Everything that is needed for survival and well-being depends either directly or indirectly on the natural environment. Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, while also helping to fulfill the social and economic requirements of present and future generations.

 

Part 1:

Background Information

Planet Earth’s surface is over 70% water, but less than 1% of the water on Earth is considered accessible, usable freshwater for sustaining humans’ and other organisms’ lives. Of the accessible freshwater, approximately 99% is located in aquifers, natural underground water chambers, and other groundwater sources. Unfortunately, humans are depleting the aquifers faster than they can be recharged by the hydrological cycle. Therefore, three quarters of groundwater is considered nonrenewable.

Conditions

The main reason we using groundwater resources mainly for drinking and irrigation. As a result, this not only decreases an important source of freshwater—it also can cause pollution of that groundwater by saltwater intrusion. The recharge rate of groundwater is further hindered by land clearing and deforestation caused by human development. When land is cleared for human development, more flooding occurs, the transpiration rate (the amount of water that evaporates into the atmosphere from plants) is reduced, and rainwater is inhibited from adequately percolating (penetrating the soil) into the ground to allow for aquifers and groundwater to be recharged.

Figure below shows Saltwater Intrusion:

(Wright & Boorse, 2010)

Impacts

Forty percent of the world’s food is produced via irrigation. As a result, if the current rate of groundwater usage continues, food production could be drastically reduced worldwide. This reduction in food supply would be detrimental in sustaining the projected worldwide human population of over 10 billion within the next 50 years.

Part 2:

Timeline

Use the Hydrologic Cycle Figure below to understand the impact of industrialization and human development on ground water over 3 centuries.

Earth System’s 4 spheres & their functions

/in /by
  1. Complete a Google search of a science topic of interest, related to this class.
  2. Select 3 articles, at least one must be from a scientific journal, to read on the topic.
  3. Write a 1/2 page summary on each article. Be sure to include a citations of the source in APA format and reference page in APA format.

 

Below are some of the things we have completed thus far in this class to give you an idea on choosing the SCIENCE TOPIC :

 

Earth System’s 4 spheres & their functions • Formation of the solar system • Characteristics of minerals • Identifying properties of minerals, i.e. cleavage, luster, hardness, etc. • Rock Types and how they are each formed • Particles of atoms, their charges, locations, and functions • Elements v. compounds v. mixtures • Different types of plates; all things related to plate tectonics • How, where, and why of earthquakes, along with terms associated with earthquakes (waves, epicenter, focus, etc) • Types of volcanoes, lava flows, and formation of magma • Mountain formation & types • Emergent vs. submergent coastlines • Desert types, dune formation, desertification, etc

Nightingale- Milestone 3 Epidemiology

/in /by

Hello- need the last part of the milestones completed: (I can send  you the rubric separately

Overview: Now that you have solidified your study question and hypothesis, you will choose a study design for the final project and consider potential interventions.

Prompt: Write a draft of Section III of the final project. Address the following critical elements in your short paper: III. Epidemiology Study Design Proposal: In this section, you will choose an analytic epidemiological study design from those covered in this class, to be used to answer your research question and examine the hypothesis. Keep in mind this is not expected to be a complete research design, which would also include a sampling strategy, a measurement strategy, and statistical methods for the study.

 

a) Select the most appropriate analytic epidemiological study design to research your study question, explaining why you feel it is most appropriate.

b) How will you use your selected study design to identify patterns, causes, and effects of health condition for the affected population of your study? Are there any limitations of the study design? Tip: refer to journal activity for your analysis of the strengths and weaknesses (or limitations) of each study design.

c) Select an appropriate measure of association (e.g., odds ratio, relative risk) based on your chosen analytic epidemiological study design. Why is this measure of association appropriate?. d) Determine potential interventions for solving the public health issue for the specified population and/

d) Determine potential interventions for solving the public health issue for the specified population and/or

community based on the epidemiological practices you have used.  How would your epidemiological study inform potential interventions? Think about the different levels (i.e., primary, secondary, tertiary).

 

Be sure to cite scientific resources that support your response. You are not expected to determine the solution for the identified issue, but instead, consider strategies that may help solve the issue based on your knowledge from this course.

 

Guidelines for Submission: Your paper must be submitted as a 2- to 3-page Microsoft Word document with double spacing, 12-point Times New Roman font, one-inch margins, and at least four scientific sources cited in APA
