Investigating U.S. Policy of Acid Rain
Acid Rain.". My prediction was correct and bags with strong and weak acid did affect the crops growth compared to the bag with the pot containing the water sample. Each bag will contain 2 plants (one wheat, one barley) three universal indicator strips, one measurement of acid, one piece of cotton wool and a small pot/tub. Extracts from this document.
According to the Office of, air Quality Planning and Standards, acid air pollution can be linked to breathing and lung problems in children, asthmatics and even healthy people. Abstract: A demonstration showing acid rain and lake acidification is described. In this demonstration, SO 2 gas is generated in a large graduated cylinder and then dissolved in water droplets from a simple spray bottle. Dale Jacques Science Investigation. Acid rain, investigation The aim of this investigation is to find out what effect acid rain has on crop growth.
In acid-sensitive landscapes, acid deposition can reduce the pH of surface waters and lower biodiversity. Acid rain contributes to the corrosion of surfaces exposed to air pollution and is responsible for the deterioration of limestone and marble buildings and monuments. In acid-sensitive areas, acid rain also depletes soil of important plant nutrients and buffers, such as calcium and magnesium, and can release aluminum, bound to soil particles and rock, in its toxic dissolved form. I will investigate this with the following experiment; I will put 2 crops named Wheat and Barley into three sealed bags with two different concentrations of acid in with them and one concentration of water. After the experiment I will compare the colour which the universal indicator strips have turned to the Ph scale this will tell me how acidic the plants atmosphere is in each bag, this will determine which concentration of acid effects which plant worst. To make this a fair test I will put the same amount of acid in each pot, I will ensure the same amount of acid will be put in each pot by using a dropper to measure the amount of acid I have put. I can prove this with the graph below:.read more. In one plant a barley plant could measure 8cm this would make the test unfair because the smaller plant would be more easily effected. Although the problem of acid rain has been significantly reduced in some areas, it remains an important environmental issue within and downwind from major industrial and industrial agricultural regions worldwide. To make sure the results are accurate I recorded the size of each plant before and after I put it in a bag with the acid this will show if an acidic atmosphere effects crop growth, the measurements are as follows: Measurements.read more. Acid rain, also called acid precipitation or acid deposition, precipitation possessing a pH of about.2 or below primarily produced from the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx; the combination of NO and NO2) from human activities, mostly the combustion of fossil. Each bag will contain one wheat plant, one Barley plant and a solution of either acid or water.
I will investigate this with the following experiment; I will put 2 crops named Wheat and Barley into three sealed bags with two different concentrations of acid in with them and one concentration of water. The causes of acid rain, how acid rain affects our environment and our health, and what regulatory actions have been put in place to reduce the pollutants that cause acid rain. Investigation of the effects of acid rain on the deterioration of cement concrete using accelerated tests established in laboratory.
