Introduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity. Research Questions: What effect does acid rain have on the growth rate of plants in the wetland ecosystem? What results are expected? What is your conclusion? Hypothesis: Acid rain will have a negative impact on the plant growth in the wetland environment, this will result in plants dying and …show more content…
Two of the same types of plants were used, in order for the results to be reliable. One of the plants was labelled DISTILLED whereas the other was ACIDIC, so the results don’t get mixed. The DISTILLED plant was used as a controlled variable, where normal spring water was used (pH 7.3) The ACIDIC plant was the one the experiment had taken place on, this was where lemon water was used (pH 2.0) Throughout the experiment pictures were taken, so one will be able to notice the colour change on the acidic plants, as it had started to slowly die. With both plants you are able to notice that they had both started to grow flowers, but more the spring watered plant than that on the lemon juice watered one. The results of the plant growth was recorded to we would be able to notice the amount it had grown, this would be the water compared to lemon juice. Materials needed: 2 pot plants. Potting soil. Two of the same type of plant. 2 spray bottles. Water. Lemon juice. Labels. Marker. Experimental
Freshwater is also looked at as floodplain management is observed. The patterns of environmental quality are also examined. My hypothesis is that pH levels and drainage account for the significant differences in vegetation between the areas. This is because both drainage and pH levels play a role in what type of soil is available. The pH level determines the types of plants that grow and the drainage effects the type of soil present, which influences the

This article highlights the reasons behind the decline of coastal wetlands in multiple locations throughout the Western-Hemisphere. For example, Bildstein et al. state that in the Everglades, contamination of the soil is threatening the wild-life and plant-life in the wetlands in that area. In addition, the article also analyzes methods that specific organizations have created to help in the conservation of wetlands.
Introduction The purpose of this lab was to test one type of grass and four different types of soil in order to figure out which grass will grow tallest in 21 days. The hypothesis states that The Perennial Rye Grass will grow taller in the Miracle-Gro Organic Potting Mix than the other three grasses when given water over 21 days. The independent variable is the soil, the dependent variable is growth measured in height, and the control variables are as follows: 21 days of data collection, 1.5 mL of water a day, sunlight from 8 a.m. to 3 p.m. in greenhouse, temperature is about 70o F, 200ml of soil in each planter, five drainage holes made with a probe, .25 grams of seed, 1 cm into the soil, watered with 1.5ml twice a day and measured after the
The question of interest is the following: what is the effect of nitrogen solution on duckweed growth? We want to know whether nitrogen will increase or decrease duckweed growth. In past experiments of the effects of nitrogen on plants, nitrogen was found to decrease plant growth when there was a deficit amount of nitrogen. An experiment was set up where plants were given 0%, 20% , and 100% nitrogen concentrations and were left for 58 days (Zhaoa, Reddya, Gopal, Reddyb, “Nitrogen deficiency effects on plant growth, leaf photosynthesis, and hyperspectral reflectance properties of sorghum”). They found, as a result, that the higher the nitrogen concentration the more growth in the plant sorghum.
However, the isotonic beaker with no NaCl solution did not cause the plant to remain at the same weight, but instead allowed it to take in a bit more water than the hypotonic solution. 5. State your conclusions about the influence of solute concentration on the direction of osmosis. In conclusion, osmosis is highly sensitive to various solutions.
This experiment is testing weather daisy seeds will grow faster in artificial light or sunlight .The purpose of this experiment is to see if the difference of light will affect the germination of a daisy. These pages of research will be explaining what this whole project means. From what soil will be in the daisies to what type of watt will be used in the lightbulb. This experiment is being tested because it is interesting to experiment the works of nature vs. man made products.
Gene Turner asserts that the 88 percent of the wetland losses are occurring without direct, on-site human effect. The book talks about four hypotheses but three are cast aside and Turner mainly believes in one. The two that were rejected blame the wetland loss to changes to the river, which then contributes to the deprivation of nutrients-rich sediment. The other dismissed hypothesis blamed the saltwater intrusion as the main culprit in the loss of the freshwater wetlands. The one that Turner strongly believes as the main reason is the one that blames the canals for the destruction of the wetlands.
The results support the hypothesis, the amount of duckweed in the containers with vinegar might have decreased due to the low pH level of the vinegar. The vinegar used in the experiment had an acidity of 5% and a pH level of 2.4, which but duckweed need a pH level of 6-7 in order to survive (McClung, 2013). The vinegar was too acidic for the duckweed to grow in, resulting in containers one and two turning white and decreasing in size faster than container three which only contained tap water. An explanation for why all three containers had a decrease in duckweed is that there was no oxygen added to them.

In an article written by Amanda Briney she talks about what governments do to help stop acid rain. “[M]any governments are now requiring energy producers to clean smoke stacks by using scrubbers which trap pollutants before they are released into the atmosphere and catalytic converters in cars to reduce their emissions. ”(Briney 3) With government doing their part to help, acid rain will start to fall less often. This will happen so long that power plants follow the rules that the government put in place.
Acid Rain is a big problem especially in the big cities that have big industries like for example: São Paulo, Shanghai, New York etc. This document has interesting facts and explanations about what acid rain consists and affects in our society. Acid rain contains elevated concentrations of sulphuric and nitric acid. It can encompass big precipitation with the presence of this two acids, this acids can also be found in snow, dried materials particles and in the fog. The green surface or also called “world’s lung” and the eruptions of the volcanoes they release some chemicals into the atmosphere, but the one who most affects the human society is the Acid Rain.
My Science project topic is How do different fertilizers affect plant growth? The way plants grow is through a process called photosynthesis. Photosynthesis is the process which a plant gets light energy or sunlight to make food for their selves. Photosynthesis takes place in the chloroplasts. The chloroplast has an organelle inside of it called chlorophyll which has a green pigment, chlorophyll is green because it absorbs red and blue light.
The effects of Acid rain as Hai-Ying Liu(15/01/2015, ) says are the direct effects of So2, extremely acidic mist or rain events or other pollutants. It also has its effects on the soil which is likely to have negative effects on forest growth in China. Defilation is a difficult thing to diagnose as insect attacks play a major role in indicating the climatic stress. Predisposing effects acid rain cannot be ruled out as an additional cause due to the difficulty to
