Lab 2 – Water Quality and Contamination

 

 

 

Experiment 1: Drinking Water Quality

 

Bottled water is a billion dollar industry in the United States. Still, few people know the health benefits, if any, that come from drinking bottled water as opposed to tap water. This experiment will look at the levels of a variety of different chemical compounds in both tap and bottled water to determine if there are health benefits in drinking bottled water.

 

 

 

POST-LAB QUESTIONS

 

 

 

1.      Develop a hypothesis regarding which water sources you believe will contain the most and least contaminants, and state why you believe this. Be sure to clearly rank all three sources from most to least contaminants.

The intent of a qualitative interview is to encourage, elicit, and illuminate the interviewee’s experience in rich, thick detail. Consider that most interviewees will only have a general idea of your research goals and the depth you need for analysis. Therefore, your presentation of the interview questions and engagement with the interviewee are the tools that guide the process.

As you consider your interview, think about:

Asking of questions to ask to encourage stories and examples

How to “reframe” questions to reduce ambiguity and bias

What you can do to make the interviewee at ease

What you can do to build rapport and trust

For this Discussion, you will examine the characteristics of a good qualitative interview.

To prepare for this Discussion:

Review the chapters of the Rubin and Rubin course text and consider the characteristics of a good qualitative interview.

Review the Yob and Brewer interview questions in Appendix A at the end of the article and consider how interview guides are used in research.

Review the Interview Guide Instructions and the Interview Guide Example found in this week’s Learning Resources and use these documents to guide you during your interview.

Post your explanation of the characteristics of a good qualitative interview. Also include what makes a good interview guide. Use the interview questions from Yob and Brewer’s interview guide to support your post.

Be sure to support your main post and response post with reference to the week’s Learning Resources and other scholarly evidence in APA style.

PLEASE USE REQUIRED READINGS AND CITATIONS. THANK YOU

Arteries, Capillaries, and veins are a network system with different functions and structures which work together to keep the body at homeostatic state. This vast system of blood vessels “Is about 60,000 miles long, that is enough to long enough to go around the world more than twice.” (Beckerman, 2019) To begin, Arteries carry blood away from the heart in a high pressure. The blood is oxygenated and brought to other tissues and organs, while veins bring back deoxygenated blood back to the heart, in a low pressure. The structure of artery contains three different layers, the middle layer is the most important  it is mainly smooth muscle which provides support for the artery, it also changes the diameter of the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells. An interesting fact about capillaries is that “About 5 percent of the total blood volume is in the systemic capillaries at any given time. Another 10 percent is in the lungs.” (Classification & Structure of Blood Vessels, n.d.). Lastly come the veins, veins not only take back blood to the heart, but veins are rich in waste products that are to be excreted or removed from the body. Veins become larger as they get closer to the heart. “The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.” (Beckerman, 2019). Veins contain the same structure as arteries but contain less muscle tissue, and connective tissue, due to this is the walls of a vein are thinner, and thus having less pressure than arteries.

Assignment 1: Discussion During Module 4, we examine why most people tend to conform in most of their social interactions, while others deviate from the existing social norms. After you have read the reading assignment and lecture for this module, please respond to all parts of the discussion by Saturday, October 1, 2016.  Why do people sometimes feel that they need to socially conform to what is going on around them, even if they do not want to do so?  How do the social institutions of our country (e.g., schools, the healthcare system, the economy, religious organizations) play a role in encouraging social conformity, as well as social deviance?  In reviewing the following video “Solomon Asch’s Conformity Experiment Today” at http://thesituationist.wordpress.com/2008/06/11/solomon-aschs-conformity-experiment-today/, describe why the individuals in the Asch experiment usually gave the same answer when they probably knew that it was wrong.  Remember to respond to the posts of at least two other students in the class. Complete your participation for this assignment by Tuesday, October 4, 2016.
