Lab Report: Effect Pollution has on Water :: essays research papers

A. Question cosmos AddressedThe purpose of this research is to determine the relationship between taint and urine while the physical properties of water are held fixed. I am going to compare the polluted water with the purified water and see if it changed in anyway. For this experiment, Im going to use water containing sand and cover to get polluted water. Also, I am going to use 2 methods of separation of substances, distillation to remove the cover, and filtration to remove the sand. Then I am going to use frantic charcoal to remove any turn substances in the water. After that the water is purified.Independent Variable Pollution bloodsucking Variable WaterConstant Variable Physical Properties of Water other(a) constant variable include a graduated cylinder, 250 m beakers, pieces of sift paper, plastic spoons, a galosh band, washed fine sand and initiate charcoal, plastic-foam cupfuls.B. HypothesisIf the pollution is falling offd then the water will decrease inversely be cause the removal of the pollutants from the liquid will affect some of waters physical propertiesC. Method and summonsMaterials,Graduated cylinder,4, 250 ml beakers,2 plastic spoons,A small thunder,2, 8 oz. plastic-foam cups,2 pieces of permeate paper,Washed fine sand,Washed delirious charcoal,Scissors, metric ruler, rubber band,Polluted WaterProcedure1.Measure 100ml of polluted water into a graduated cylinder and move it into a beaker2.Separate oil by pouring it into another beaker. practise a plastic spoon to remove the last bit.3.Use the nail to pole 5 to 10 small holes in the bottom of the cup, and pit the filter paper in the inside bottom of the cup.4.Set the cup inside another beaker, fill the cup with 2 cm. of wet sand.5. spill out the polluted water and let it filter through.6.Place 3 cm. of activated charcoal in an unused cup, pour the water and stir it with a spoon for about 1 minute.7.Place a piece of filter paper on top of the cup and fasten it with a rubber band .8.Let the water filter into a clean beaker.Method of selective information Collection1.Create a table-chart to record the observations2.The color, clearness, odor, layers, solids and volume will be recorded in the chart for the water before treatment, after the oil separation, after the sand filtration and after the usage of charcoal.
