Dependence of man on the environment Essay

Three experiments were conducted during hebdomad two. The first was to find how many contaminates that we put into our H2O supply will make our groundwater. The decision that I arrived at was. that there are still big leftovers of contaminates in the groundwater supply after it has had a opportunity to be passed through dirt. We emulated this affect by utilizing smaller sums of contaminates such as oil. acetum and laundry detergent. Put them in a smaller sums of H2O and so passed them though dirt. Introduction In the debut. I will name the jobs with our world’s H2O beginnings. Contained in the articles written by: The Natural Resources Defense Council. Water. These beginnings go on to province jobs that we are confronting as a population with our H2O quality. Some of these jobs are big sums of H2O waste. the big metropoliss that are traveling to confront a clime alteration that will change their dependance on H2O. They besides note that soiled H2O is the world’s largest wellness hazard and it continues to endanger the quality of life and the public wellness in the United States. The first job is that people don’t cognize how of import holding clean H2O is until it’s no longer easy accessible for them. When people become more informed about the jobs that we are confronting and will confront really shortly as a society. We can take certain stairss to seek to forestall it and to guarantee our quality of life non merely stays the same. but improves.

Small can be accomplished by one. but if we work together and seek to conserve and maintain our H2O clean. it can last much longer. The aim of this experiment is comparatively simple. to educate on how much we affect our environment by the actions we take and what we can make to better our wonts to guarantee that our H2O supply will last much longer and have good quality. It besides has the intent to allow people cognize that their actions don’t merely impact them or merely the people that they live about ; it besides affects the environment and the animate beings that inhabit it. During the experiment of the Water Quality and Contamination my hypothesis were ; The Oil hypothesis was that if there is oil in the surface H2O so. I think when the H2O is passed through dirt it will be able to filtrate out the oil before it reaches the groundwater. The hypothesis for the acetum hypothesis was if there is acetum in the surface H2O so. I think that when passed through dirt it will still stay in the groundwater.

My laundry detergent hypothesis was if there is laundry detergent in the surface H2O so. when it is passed through dirt it will still hold hints of laundry detergent in the groundwater. The following experiment’s hypothesis was that utilizing peculiar chemicals and methods of filtration. we should be able to take most of the contaminates that are in the groundwater. This was the experiment that involved different methods of Water Treatment. The concluding experiment pertained to the imbibing H2O quality and my hypothesis was that tap H2O will incorporate the most contaminates because of its way and unknown status. The bottles of H2O are in a more unfertile environment. The Dasani H2O is treated and Fiji comes from a natural spring. The treated H2O ( Dasani ) will hold the least sum of contaminates. Materials and Methods

The first experiment that was conducted used dirt. different beakers. wooden splash sticks. vegetable oil. acetum. liquid laundry detergent. H2O. cheesecloth and funnels. I poured H2O into each of the first 4 beakers. and so put vegetable oil. acetum and laundry detergent in severally. I stirred them with the wooden splash sticks and used the cheesecloth to line the funnel and set dirt in and poured each of the different contaminates through. replacing the dirt and cheesecloth each clip. The 2nd experiment involved beakers. dirt. cylinders. sand. wood coal. crushed rock. wooden splash stick. alum. funnel. cheesecloth. bleach. stop watch and H2O. I added dirt to a beaker and put H2O with the dirt and assorted them with two beakers 15 times. I divvied some on the contaminated solution into a new beaker and added alum to it. I stirred the mixture with a wooden stick for 1-2 proceedingss and so allow it sit for 15 proceedingss. I lined a funnel with cheesecloth and superimposed sand. wood coal and crushed rock into the cheesecloth.

I poured the clean pat H2O through the filter and repeated 4 times. I poured ? of the contaminated H2O into the funnel and allow it filtrate for 5 proceedingss. I annotated the odor and compared to the mixture in measure 3. I added a few beads of bleach and stirred the combination for 1 minute. I so compared and annotated the now filtered H2O to the initial contaminated H2O. The concluding lab contained Dasani bottled H2O. Fiji bottled H2O. Ammonia trial chevrons. Chloride test strips. 4 in 1 trial strip. phosphate trial strips. Fe trial strips. beakers. marker. stop watch. Parafilm. pipettes. foil packages of cut downing pulverization and tap H2O. I labeled each of the beakers and poured Dasani. Fiji and tap H2O in each of the three beakers. I gathered the ammonia trial strips and placed in the H2O and moved them up and down smartly for 30 seconds each. I held each tablet degree for 30 seconds to acquire a reading. I did this 2 more times for each of the beakers. I so retrieved the chloride trial strips and immersed the reaction zones in each of the three beakers one at a clip for 1 2nd each. I shook off the extra liquid and determined what color the trial strip was. I so used the 4 in 1 trial strip and dipped in each of the beakers once more. one at a clip. for 5 seconds and wiggled back and Forth.

I briskly removed the extra H2O and waited 20 seconds to read the consequences. I so used the phosphate trial strip by dunking in each of the beakers signally for 5 seconds and so removed and held horizontal for 45 seconds. go forthing the extra H2O on the trial strip and recorded the consequences. Finally. I used the Iron trial strip and removed 70 milliliter of H2O from each beaker and tested 30 milliliter of each of the three beakers. I added one foil package and covered with parafilm and agitate the beaker for 15 seconds. I removed and dipped the trial tablet into the sample and moved it back and Forth under the H2O for 5 seconds. I removed and shook the extra H2O off and tested and compared 10 seconds subsequently.
