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

A. Question Being AddressedThe think of this research is to determine the relationship between pollution and irrigate man the sensual properties of piddle are held fixed. I am going to liken the begrime water with the purified water and see if it changed in anyway. For this experiment, Im going to use up water containing vertebral column and oil to get grime water. Also, I am going to use two methods of separation of substances, distillment to remove the oil, and filtration to remove the sand. Then I am going to use activated charcoal to remove any dissolved substances in the water. aft(prenominal) that the water is purified.Independent Variable PollutionDependent Variable irrigateConstant Variable Physical Properties of WaterOther constant variant include a graduated cylinder, 250 m beakers, pieces of filter wall news report, elastic spoons, a rubber band, washed fine sand and activated charcoal, fictile-foam cups.B. HypothesisIf the pollution is decreased then the water will decrease inversely because the remotion of the pollutants from the liquid will affect some of waters physical propertiesC. Method and ProcedureMaterials,Graduated cylinder,4, 250 ml beakers,2 plastic spoons,A small nail,2, 8 oz. plastic-foam cups,2 pieces of filter paper,Washed fine sand,Washed activated charcoal,Scissors, deliberate ruler, rubber band,Polluted WaterProcedure1.Measure 100ml of polluted water into a graduated cylinder and pour it into a beaker2. set out oil by pouring it into other beaker. Use 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 fit 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.Pour 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 to the highest degree 1 minute.7.Place a piece of filter paper on top of the cu p and fasten it with a rubber band.8.Let the water filter into a clean beaker.Method of Data Collection1. ready 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.
