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

A. Question Being AddressedThe purpose of this research is to determine the relationship between pollution and water while the animal(prenominal) 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 give water containing sand and oil to get polluted water. Also, I am going to use two methods of separation of substances, distillation to remove the oil, and filtration to remove the sand. because I am going to use activated charcoal to remove any dissolved substances in the water. After that the water is purified.Independent Variable contaminantDependent Variable WaterConstant Variable Physical Properties of WaterOther constant variable include a graduated cylinder, 250 m beakers, pieces of dawn paper, moldable spoons, a good-for-naught band, washed fine sand and activated charcoal, plastic-foam cups.B. HypothesisIf the pollution is decreased then the water will decre ase inversely because the removal 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, metric ruler, rubber band,Polluted WaterProcedure1.Measure 100ml of polluted water into a graduated cylinder and pour it into a beaker2.Separate oil by pouring it into another 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 fuddled 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 about 1 minute.7.Place a piece of filter paper on top of the cup and fasten it with a rubber ban d.8. permit the water filter into a clean beaker.Method of Data 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.
