Introduction Acid rain is not a naturally occurring thing, acidic precipitation happens due to high amounts of sulfur and nitrogen being released into the atmosphere. It usually forms and comes together when natural sources such as volcanoes and man-made sources such as industries and transportation release sulfur and nitrogen, it then reacts with the water and oxygen in the atmosphere, forming sulfuric acid, ammonium nitrate and nitric acid which increase the amount of acidity of rain. As a result of this, we have rain that can deteriorate paint and even corrode metal. The EPA has also said that it can have a negative impact on things such as lakes and forests. When acid rain hits the soil it can have a number of negative impacts such as , trees become more vulnerable to disease, extreme weather, and more. Acidic rain may not kill trees in an instant or may i say directly but over time it gets rid of nutrients that trees need to live and will produce many chemicals in the soil that can be very harmful.Hypothesis If three samples of fescue grass are watered with both water and different levels of pH then the sample with the least amount of acid will grow the best.Materials3 cut in half milk cartons Potting soil Fescue grass seeds Ruler Marker VinegarOrange juice Water StepsCut milk cartons in half Mark 3 cartons with marker at 7inLabel each carton A,B,CFill cartons with soil till reaches fill line Plant seeds in each of the cartons Water carton A with water Water carton B with water and grapefruit concentrateWater carton C with vinegarRecord length and observations everyday Repeat once every day for 7 days DataSamples of pH in cartonSoil observations Grass observations Carton A pH level of 7Moist, clumped together Bright green, moist, 2.1in Carton B pH level of 3 Dry, light brown color light / dull green, 1.3inCarton C pH level of 2Dry, light brown color Yellowish kinda green, 1in ConclusionThe result of this experiment is supported by my hypothesis: “If three samples of fescue grass are watered with both water and different levels of pH then the sample with the least amount of acid will grow the best”. According to my data table carton A with the least amount of acid grew the best with bright green grass, moist soil, and growing to be much taller than the other getting to about 2in. On the other hand carton C and B grew very poorly not getting to be very tall with dry unclumped soil, both having a dull green/ yellow color to it, hence supporting my claim/ hypothesis.The EPA states “Acid rain usually has a pH between 4.2 and 4.4”. Meaning that carton B with water and a pH level of 3 most accurately represents how acid rain affects grass just over the span of a week. My experiment shows that just in the matter of a week acid rain can be very damaging, making grass go from bright green and firm soil to dry crumbly soil with yellowish grass. The reason for this is because the acidic water being put in carton B washes away and dissolves the nutrients essential for grass and plant growth, the essential nutrients include calcium, magnesium, and potassium. They help the plant build new cells and also transport sugar throughout the plant. Without theses essential nutrients the plant will grow poorly and eventually die.In conclusion this experiment realistically simulated what kind of drastic negative effects acid rain can do to grass and plant life. It can be said that any rain or precipitation with a pH level lower than 4 can have even more negative, plant damaging effects and on the other end any perception with a pH level higher then 6 is very good and has positive impacts on plant growth.
