Through this experiment, we might be able to find ways of increasing the growth of the plants found in our garden. Scope and Limitations The researchers will try to determine whether different substances (water with salt, sugar, powdered milk or water only) will affect the growth of the plants. They will be allotting 2 months for us to see if the water mixtures namely water with salt, sugar, and powdered milk can affect the growth of plants. The plants in trial 1 will be receiving enough sunlight while trial 2 will not be receiving enough sunlight, watered equally and have a control set up so that we can compare the results after the time allotted for the experiment. They will not be spending as much because most of the products they will be using are found at home. They will be having a PH. 500 budget to buy materials that we will need but couldnt find them at our houses. The Independent variable will Include the plants we used In testing, water with the mixtures. The dependent variable will be the result of dealing with or experimenting nee Inaepenaenvexperlmental variable. In tens case, It will De ten amount AT sugar, salt, and powdered milk that they will mix with the water to see if these will affect the Peachy plant we will be using for our experiment. Their controlled variable will consist of the peachy plant and water. Review of Related Literature Tap Water on Plants Tap water is good for plants that need water with chlorine in it, spring water is good for carnivorous plants in order for them to grow, and bottled water is good for plants like cactuses that need mineral water to grow. Sugar on Plants Plants require three essentials, light, water and nutrients to thrive and produce optimum yield. Plants naturally produce sugars, such as glucose and sucrose. These sugars are needed to produce energy, promote growth and aide in the processes of respiration and transpiration. Sugar can also be introduced to a plant through watering to enhance growth and production. Sugar, in moderation, is not harmful to plants. If the amount of sugar in the soil becomes too high, this promotes a higher incidence of fungi and bacteria. A typical fungus that thrives on sugar is yeast. In a study at University of Southern California, here groups of bean plants were watered with different degrees of sugar water (O g, 25 g and 50 g solutions). The group of plants which had been watered with the 50 g sugar/water solution was not only the largest and strongest of the plants, they were also the healthiest and highest yielding plants. Effect of Salt Concentration on Plant Growth Many western farmers believe that soil alkali is more detrimental to crop growth during the hot weather than during the cooler seasons of the year. Other agricultural workers have noted that damage to crops due to alkali (soil salinity) is more serious in he hot interior valleys than along the coast where the climate is more moderate. It is not definitely known whether or not soil salinity concentrations are comparable between different seasons of the year or between respective areas. Yet, information on this question is pertinent to the development of management practices which would aid in ameliorating soil salinity conditions at different seasons of the year and under different climatic conditions. The results obtained in this study show that* most crops are injured by salt to a greater extent in warm than cool climates. The Effect of Water Impurities on Plant Growth The purpose of this experiment was to determine the effect of water impurities on the growth of plants. Each plant was put near a big window that let in a lot of sun. Two different stems from each plant were marked with bag ties. The heights of the two stems from each plant were measured. The plants were watered with 157. 6 millimeters of the solution. Each plant was watered on Thursday and Sunday. The first solution contained six millimeters of Colors bleach and 151. millimeters of water. The second solution contained 6 grams of sugar and 157. millimeters of water. The third solution contained 6 grams of salt and 157. 6 millimeters of water. On Friday and Monday the height of the stems of each plant were measured, and the height was recorder. I nerve was also a plant Tanat was watered Just Walt water, Tort ten control setup. This experiment ran for four weeks. The data was analyzed to determine which plant grew the most over that period of four weeks. The conclusions of this experiment are that the plant watered with sugar grew the most. Another conclusion is that the control (the plant watered with water) grew a little less than the plant attired with sugar. The plant watered with salt grew a little less than the control, and the plant watered with bleach grew the least amount. The reason that was discovered for why the plant watered with sugar grew the most was because when plants absorb nutrients, they turn them into some form of sugar. This plant didnt have to do that because it was already absorbing sugar. The other substances, except water, probably Just stopped the plants from growing as much. Plant Growth Experiments The instructions below outline a protocol for conducting plant growth experiments in the laboratory. You may want to make adaptations for use in a greenhouse or outdoors. Purpose: To determine the effect of compost on plant germination and growth. Materials: pots, compost, soil, seeds, light source (sunlight or artificial light) Procedure The first step is to design your own experiment. There are many possibilitiesa few ideas are listed here, but the variations are endless: 0 Test various combinations of soil and compost on plant growth. For example, you might wish to dig a soil sample from your school yard and mix it with various amounts of finished compost for planting experiments. Natural soil is better than prepackaged potting soils for experiments such as this because the potting mixes are formulated for optimal plant growth and already contain significant amounts of compost or humus. ) 0 another possibility is to mix your own potting soil by using vermiculite, sand, and compost. Creating several mixtures using the same percentages but different types of compost is a good way of comparing the influence of the various types of compost on plant growth. For example, you could compare compost at various levels of maturity, compost created using different mixtures of organic wastes, or overoptimistic versus impost created in a thermometric system. 0 if you are interested in investigating the effects of compost tea on plant growth, you could fill the pots with a sandy soil or potting medium such as vermiculite, then use compost extracts for watering. Next, whatever type of experiment you choose, make sure that you design your experiment to include replicates of the various treatments.

Gluclose effects on osmosis essays

Gluclose effects on osmosis essays Studying the Effect of Various Glucose Concentrations on Osmosis in a Potato Osmosis is the process in which water particles move from an area of high water concentration to an area of low water concentration through a semi-permeable membrane until the concentrations are equal. Osmosis has the same basic theory as diffusion. Particles are moving from an area where they are in great concentration to an area where they are in low concentration until the concentrations are the same. Osmosis is this movement of water particles and the particles must move through a semi or partially permeable membrane (a membrane that lets some things through but not others). An example of this type of membrane is a cell wall, like in a potato. Osmosis occurs when two things occur. One is if the cell has no water in it or has less water then the solution it is placed in. If this is the case then water will go from the solution, for it is the area of high water concentration, into the cell, for this is the area of low water concentration. If the cell has no water within it the cell is flaccid. As the water passes through the cell membrane, the cell fills with water and becomes turgid. Once the cell becomes turgid, no more water can enter the cell and osmosis stops. The other incident that can happen for osmosis to occur, is when the concentration of sugars or other minerals in the cell is different then that of the solution it is placed in. This is because the amount of sugar in the water either in the cell or in the solution is going to change the water concentrations as well. Whichever solution, either in the cell or not, contains a higher sugar concentration will have a lower water concentration. If the solution in the cell contains more sugar, salt or other minerals then the solution it is placed in, then it will have a lower water concentration. This will cause water from the external solution to pass through the cells semi-permeable ...

News of the World Research Paper Example | Topics and Well Written Essays - 500 words

News of the World - Research Paper Example The news that shocked the world though is that in the mid-2011, it was announced that News International, the new owner of the tabloid will stop publishing News of the World. This is based on the result of the controversies surrounding the data gathering process of the tabloid. Prior to the event, the company was charged of phone-hacking to be able to get information for the tabloid. The said crime used to be allegations but evidences surfaced and the company was attacked by the public. The last issue of News of the World was released on the 8th of July 2011 after more than a century of running. The owners had to make the move to stop the publication due to the fact that it cannot overcome the political and commercial attacks that can occur through the years (Robinson, Scott and Sweney). One of the main reasons for the collapse of the News of the World is the phone-hacking. The said action became controversial because it is against the ethical rules of journalism and can be considered disrespectful to private citizens. One of the events that tainted the reputation of the paper is the case of 2007 when Clive Goodman was imprisoned for phone hacking. He is the paper’s royal correspondent. But the said matter did not end there. Another serious case of phone hacking is related to British teenager Milly Dowler who was found dead. Based on these cases and the corruption within the tabloid’s structure, the News of the World had to close down (Addley). Due to the cases of phone hacking committed and made famous by the News of the World, the Editor’s Code of Practice which used to be considered sufficient to cover ethical concerns in journalism had to be amended. The tabloid had one of the newspapers with numerous achievements but in the past years, the paper turned from dedicated journalism to being limited to trends and pop culture. When new issues such as pedophile, corruption, crimes, etc. would suffice in the media, News of the World would
