The Effects of Detergetn Pollution

In this experiment we are testing the effect of fertilizer on the speed of plant growth. We prepared a 4 quad cell, 1 control group and 3 experimental groups. So, we had one with no fertilizer, one with three seeds of fertilizer, one with six seeds of fertilizer, and lastly, one with nine seeds of fertilizer. The plants that we grew were called Wisconsin Fast Plants, members of the crucifer family. These plants are small and easy to grow, but for optimal growth they require continuous fertilizer, water, fluorescent light, and temperature between 18 degrees Celsius and 26 degrees Celsius 24 hours a day. Fertilizers are substances that are put into soils to increase the growth of the plant. There are two different types of fertilizers, synthetic

Throughout this experiment, we are researching the effect on the growth and survival of Wisconsin Fast Plants using fertilizer pellets to help with the growth of the plants. Wisconsin Fast Plants is a plant member of the crucifer family which is related to other plants (vegetables) such as cabbage, broccoli, turnips, etc. This plants are small and can grow very easily because they go through their cell cycle around 40 days. Wisconsin Fast Plants Fertilizers are different materials used that can provide plants with the nutrients it need to grow. (1) These plants are a good model system to study because they grew very quickly and didn’t need a lot of resources to grow making them the perfect plant to use for studies. (4) By using the fertilizers,

After extensive research, I believe that the more acidic the soil is, the slower it will be for the Fast Plants to grow. The soil’s pH is a crucial part in growing a healthy plant because “all plants require different levels for proper growth” (Lovejoy). The independent variable in this experiment is the Acidic buffer solutions; which consist of pH 2, 4, 6, and 7. According to Chemguide.co.uk, “An acidic buffer solution is simply one which has a pH less than 7.” It is very important that we as students understand the effects acidity has on plant growth. Studying the growth of the Wisconsin Fast Plant helps students have a firm understanding of this topic which in turn can help clean and prevent pollution throughout our country, making it a better and safer world for the

More than half of the human population knows what pollution is but we are still not ready to face it's damaging consequences. Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollution comes in many forms and no matter where you live, you've probably seen some form of it. Some litter of NYC city streets to the smog that lingers ov0er LA to the plastic trash that floats in the Great Pacific Garbage Patch, the visible signs of pollution are more than evident. The main reason for a why pollution has gotten too out of control is that our desire for more “stuff” has led to our old stuff being thrown away at an alarming and unnecessary rate. As humans we have impacted the environment in so many different ways. The 3 main pollutants i will be talking to you about is water, air, and soil pollutions since these are the three main ones that are affecting not only us as humans but our planet that we live on.. These three main pollutants have affected the environment in many different ways such as climate change and even habitat destruction towards our planet and is in need to be taking some Extreme Measures and actions in order to decrease the pollution to our home.

Water Pollution has been an increasing problem over the last few years. Pollution comes from many different things; agricultural, urban runoff, industrial, sedimentary, animal wastes, and leeching from landfills/septic systems just to name a few (Resources). The reason why pollution has increased over the years is because the rise in population and the advancements in technology the society has made. If society plans on having their resources here for many years to come they are going to have to make some drastic changes in the way they treat the earth, and these changes will have to start with their pollutants (Foundation).

This lab was conducted to see what happens when black tea and water are used to enhance the growth of a radish plant. The hypothesis was that the plants that were given the black tea and water mixture were going to grow faster than the control plant (Devonte). The hypothesis was partially correct because all the plants grew substantially large closer to the end of the lab. Plant 2 (Bravo) started to wither away and die because it was over fed, and eventually drowned in water. The other two plants grew at a consistent pace and developed into healthy mature plants. To sum up, the lab that was conducted was successful in the sense that two out of the four plants grew rapidly without the use of enhancements or

All of the plants were placed in the same environment with and all of the same contributing factors. There were fifteen sunflower plants each set watered with their specific liquids. By the end of week four, all of the milk plants irrigated with milk were wilted, bent over and dead. Two of the coke plants irrigated with coke were also starting to wilt, bend over, and die. By the end of the experiment the only plants that were healthy and alive were the sunflowers saturated with water.

The control group in this experiment is the group that is grown normally to test the effects of the rest of the experiment’s independent variables. Growing Brassica rapa plants in the control group will allow the other science experiments to be compared to the normal growth of a common Brassica rapa plant. The normal growth of these plants will be important in measuring the other plants to see how their sizes compare and to show how an untreated plant would grow. Because of the nature of the control group, there is no null hypothesis since all the plants should grow at the same rate. If the correct amount of sunlight and water are given to the Brassica rapa plant, then they should grow as a normal Brassica rapa plant would. The purpose of this

The outcome that would support our hypothesis would be that the Brassica plants that have been treated with Malathion pesticide will have less height, less buds, and less root density than the Brassica plants not treated with pesticide. The outcome that would fail to support our hypothesis would be if the Brassica plants treated with malathion pesticide have equal or close to equal height, number of buds, and root density. Our hypothesis would further not be supported if, at the end of the experiment, the Brassica plants that were treated with pesticide have greater height, number of buds, and root density than the plants not treated with the Malathion

There was very little change in plant height in either the control groups or the experimental groups. The control group’s plants both died at seven week while the experimental group lived three weeks longer.

There is a drought in California which is in turn affecting the number of crops that can be grown in a given amount of time. Farmers now must find a way to grow crops in an economical fashion while also maximizing each yield as much as possible. However, plant growth can be influenced by seed variety, the amount of water, the soil type, amount of light, etc., and many other variables. For this experiment, we are testing the growth of the Brassica rapa, a mustard plant under the same conditions of water, sunlight, and oxygen, with two different treatment solutions. There will be two pots, one has a treatment of just deionized water and the other a treatment of fertilizer as well as deionized water. Because the fertilizer has the added benefit of nitrogen, phosphorous, and potassium along with the same quantity of deionized water as the first pot, it is hypothesized that both sets of plants will grow, however the pot with fertilizer will grow more than the pot with just water treatment.

Seeing as quad one is the control group, no fertilizer was added, giving only natural occurring results. Within the experimental groups, three fertilizer pellets were added to each cell in quad two, five fertilizer pellets were added to each cell in quad three, and ten pellets were added to each cell in quad four. The dependent variable is the growth of each Fast Plant, seeing as any one of the independent or dependent variables could have an impact upon the final results. The control variables include water, potting mix, light, number of seeds, as well as container size. After researching the life cycles of Wisconsin Fast Plants, a final hypothesis was made that based on its known genetics, the quad with the most fertilizer pellets would grow at a more rapid rate than the remaining three. It was concluded that the benefits of fertilizer added to the already rapid growth of the Fast Plant, would further speed up its life

The results showed There was a preference in treatment on the species Trifulium spp. (χ2 = 205.20; p = 2.19x10-42; df = 2). The same result was observed for the species Raphanus spp. (X2=497.80;p=4.50x10-139;df=2) An analysis of variances was performed on the data in order to identify where was the significant variation on the respective shoot lengths of both species. Results showed that there was no significant variance in neither of the species between the shoot’s length and the treatments used. (Table 2) The same analysis was also done for the root’s length of both species. Results demonstrated that there was at least one significant difference between the three treatments and root’s length in both types of plants. It was found in clover root’s length that a comparison of the control group and Rhizobium treatment on clover root’s length were no significant different from each other (Tukey HSD: p>0.05). There was a significant difference when comparing all other types of techniques used (Tukey HSD: p<0.05). In radish root’s lengths the results showed that there was a significant difference when comparing the Urea technique against the Control group (Tukey HSD: p<0.05). There was no significant difference on the other two comparisons (Tukey HSD:

Purpose of Project The purpose of this project is to see if there is a difference in how plants grow based on what they are watered with. By watering five different plants with five different liquids and measuring them daily we will prove or disprove the hypothesis.

The 20 wheat seedlings was the sample size used in each of the five treatments, see Table 1. Among those 10 unpaired t-tests two out of the 10, Test 5 (Shoot length 1XCM vs 4XCM) and Test 6 (Seedling biomass Water vs 1XCM) had actual p-values greater than 0.05 (see Table 1). The calculated t-values for the previously mentioned two t-tests were lower than the critical t-value, 2.024 (see Table 1). For shoot length (cm), the trend shows mean shoot length to increase with increasing concentration of nutrient treatment until 3XCM, where the mean and standard deviation is at its greatest (x̅= 27.945cm±5.605cm) and drops slightly at 4XCM (see Figure 1). The pattern of the mean biomass (g), increases up to treatment 2XCM (x̅=0.2275g±0.0488g) at which mean values begin to decline a slight degree afterwards (see Figure 2).
