Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below.
1. What patterns do you observe based on the information in Table 4?
1. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?
1. What would your experimental approach be to test this hypothesis?
1. What would be the independent and dependent variables?
1. What would be your control?
1. What type of graph would be appropriate for this data set? Why?
1. Graph the data from Table 4: Water Quality vs. Fish Population (found at the beginning of this exercise). Describe what your graph looks like (you do not have to submit a picture of the actual graph!!).
1. Interpret the data from the graph made in Question 7.

...WATER QUALITY AND CONTAMINATION Name: Instructor: Institution: Course: Abstract The experiment was based on the identifying the effect of different contaminants on ground water. The yielded result indicated that, when vinegar is filtered through dirt the vinegar filtrate was relatively clean. The results noted were indicative that vinegar is not affected by contaminants that affect. Introduction In the lab report, we will have a look at how various contaminates influence the water supply. In the world, there are various contaminates that contaminate ground water. These contaminants range from the simple items we use in the house such as cooking oil and laundry detergents to the well-known contaminants that come from agricultural and industrial processes. The experiments sought to answer the question how and why these particular contaminants affect what we drink from the faucet. One of the most common contaminants in water is lead. Studies have indicated that had a detrimental effect on children especially those in the development stages of their life and cancer in adults. According to Bruce Lanphear, a renowned pediatric epidemiologist, lead found in water is usually underappreciated service in terms of intake of lead. Statistics has shown that approximately 10-20% of children are exposed to lead through intake of drinking water. Pharmaceutical chemicals are another common contaminant of water. Many individuals usually do not know that they are exposed to this...

... 110 percent. Concentrations above this level can be harmful to aquatic life” (Why Dissolved Oxygen is Important, 1998-2015). 3. Construct a hypothesis – Based on your observation in question 1 and your background research in question 2, develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water? Answer = The larger the amount of oxygen that is dissolved in water, the lower the amount of fish in a population that is being tested. 4. Test with an experiment – Describe an experiment that would allow you to test your hypothesis from question 3. This description must provide ample detail to show knowledge of experimental design and should list the independent and dependent variables, as well as your control. Answer = Since there are different factors that can affect the accuracy of testing dissolved oxygen in water I would conduct my experiments at specific times for several days, while maintain the same temperature.  For example, if I had three tanks, which had ten fish in each one and all, tanks were kept at the same temperature.  I would gradually increase the ppm to see if I received the same results.  I would also repeat the experiment and calculate the changes when the water is at different temperatures.  5. Analyze results – Assume that your experiment produces results identical to those seen in Table 4, what type of graph would be appropriate for displaying the data and...

...Kedeisha Carty LAB QUESTIONS 1. Identify natural and human-made causes of climate change visible in the computer simulation. According to the computer model, how have sources of heat-trapping pollution changed from 1750 to today? How does the simulation predict they will change by 2050? The sources of heat-trapping pollution, carbon dioxide, methane and nitrous oxide have grown since 1750 to today and pushed up the temperature from 57ᵒF to 59ᵒF and by 2050 the temperature rose to 63ᵒF showing an even higher increase of pollution in a shorter span of years. These three sources occur naturally and are also produced by human acts. According to the simulation’s prediction, carbon dioxide and nitrous oxide pollution in 1750 were most dominant with carbon dioxide in the lead, while methane was attributing the least amount of heat-trapping pollution. The simulation’s prediction of heat-trapping pollution in today’s world showed an increase in heat-trapping pollution build-up within the atmosphere and like before the sources were carbon dioxide (more dominant) and nitrous oxide; methane remained at a low concentration as before. By the year 2050, according to the simulation, the heat-trapping pollution increased at a higher significant rate than 1750 and today by 2050. In fact all three sources of heat-trapping pollution seemingly were at an even level in the polluted air. 2. According to the computer model and your readings, which source(s) of heat-trapping pollution...
