Water Quality and Contamination

5. The lid was cautiously lifted a little to allow air in but did not allow any white smoke to escape

8. I added the 3 ml of soap to the beaker and stirred the solution 40-50 times with a fresh pipette.

- Get 5 50mL beakers and fill the first one with 30 mL of water

33.While playing at the playground as Miracle was blowing bubbles I had to mix more bubble solution

6 cylinders of the same size by using a cork. I got six beakers and filled each with 20 mL of the

The 3 remaining beakers were blown into through a straw for 2 min and step 5 was repeated for each of the beakers.

To begin with, I started with two 250 mL beakers about one meter apart. Beaker A was

After materials have been gathered for the first experiment, make five solutions. For the first solution measure out 50mL of deionized water in a 50mL graduated cylinder and use a pipette to make your measurements more precise. Pour the water from the graduated cylinder into one of your beakers, label it and set it aside. For the second

3. In one of the test tubes add sugar and mix it in with the water

the plated diluted suspension to determine the number of organisms per mL that were present in the original solution.

During part A of the experiment, the solution and LabQuest was prepared. The 300 ML

Step 3: For 10 seconds, capture as many beads as you can, using a plastic spoon and place them into another container.

10. I dried each chip with the paper towel and then placed each one on

16. Steps 12-15 were repeated for the remaining salt concentrations (flask “5%” contained 5% salt, i.e. 5 g salt and 75 cm3 of water; flask “10%” contained 10% salt, i.e. 10 g salt and 70 cm3 of water, and so on).

“Time Magazine, had reported that, “over 4,000 chemicals have been found in our drinking water.” This may not seem serious, but it is Water quality is sometimes unseen, it is a serious issue yet often ignored by many. Most people are convinced that bottle water is the best solution therefore no one really questions the quality of tap water. As a result, tap water is rarely investigated, and this leads to a detrimental issues. A three-year study was conducted, for the testing of water quality, as a result the report has found more than 200 unregulated chemicals in the tap water of 45 states. This seems very alarming and devastating water quality, however, that may not be the case. The most common bottled waters are Fiji® Bottled Water and Dasani bottled water share the same common traits. Much of bottled water 's popularity comes from the perception that it tastes better. However, in blind taste tests, people cannot tell bottled water from tap water and, in some cases, prefer water from the tap. For a small scale experiment on this Water is crucial for our environment and our survival as a species. It is the key element that completes us because humans are composed of 25% of water. Since we are dependent on water it is necessary for the water to be clean. Since we are so dependent on Water, we must understand the importance of water quality. There are several dangers that water quality can have on our planet. Experiments that will be conducted to show how chemicals change
