Soil Testing Lab Report
Experiment
8.1.1 Study design and duration
• A soil testing experiment has been conducted for a period of 7 days at Amna Bint Wahab School’s chemistry lab at a constant temperature of 220C.
• A Study on plant growth has been conducted for a period of 4 weeks (28 days) at Amna Bint Wahab school’s outdoor compound during winter season.
8.1.2 Study population
• Eight soil samples were collected from four farms in Qatar (Al-Shahiniya, Al Shamal and Al Khor). The pH and EC of the soil samples was monitored in two experimental sets:
a) 1st Set = 100 ml water + 50 g soil sample + 50 g Organic fertilizer (40 g FYM fertilizer + 10 g Leaf mold)
b) 2nd Set = 100 ml water + 50 g

Addition of organic matter (FYM + Leaf mold) to the soil samples has raised the EC of the soil samples (EC value reached 323 µS/cm). Inorganic fertilizer (NPK) has raised the EC of the soil samples similarly (EC value reached 324 µS/cm) [Table-2/ Fig.2]
Results from experiment-2 displayed that addition of organic and inorganic fertilizers raised the electrical conductivity of the soil in a similar way. This increase in the amount of salts could benefit the farmers for growing organic crops and increase the crop production.
• From the study of plant height using organic and inorganic fertilizers it can be concluded that plants grew taller when organic fertilizer and inorganic fertilizer was added to the Qatari soil.
Results from experiment-3 clarified that inorganic fertilizer had the maximum growth which can be related to fast release of nutrients and abundant nitrogen present in it. Even then, organic fertilizers have shown the plant growth with almost the same magnitude hence can give a good crop yield with better nutritional value.
10.2. Questionnaire to farmers:
On analyzing the response from the farmers of 4 different farms located in north east of Qatar, we could conclude the following

Salt Creek And Barker Lake Lab Report
566 Words | 3 PagesIn this lab we were trying to figure out if Salt Creek and Barker Lake had the correct chemical balances to sustain catfish for the years coming. In order to find this out, we tested the water using a Hach Water Testing Kit. Inside were dissolved oxygen reagent powder pillows 1, 2 and 3 which we added and mixed into our sample water to prepare it for testing. Then we added droplets of Sodium Thiosulphate Solution into the prepared water too see how much dissolved oxygen parts per million were in the water. Our independent variable in this experiment was the 5 different testing sites that we went to for water samples.
Hastings Point Lab Report
1610 Words | 7 PagesIntroduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.
Miracle Gro Lab Report
915 Words | 4 PagesThe data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is the amount/concentration of miracle gro’.
Pglo Lab Report
465 Words | 2 PagesGenetic engineering is changing the DNA code to express different traits. A plasmid is a circular piece of DNA that contains important genetic information. Recombinant DNA is the product after inserting your desired genes. The genes we hoped to insert in the pGLO lab were the GFP gene and the ampicillin resistance gene. GFP was needed so that we would tell if the ampicillin resistance gene had been properly placed when the bacteria glowed under a UV light.

1035 Words | 5 PagesCatherine tells the reader that organic food could produce plenty of food for the whole world. She says “when the same products are grown, organic yields are 8% to 19% lower on average than conventional farming yields... We currently grow far more food than is necessary.” (COFFtW).
Substrate Concentration Lab Report
181 Words | 1 PagesHypothesis: Increasing substrate concentration will increase the initial reaction rate until it stops increasing and flattens out. Independent Variable: Substrate concentration Dependent Variable: The substrate itself, 1.0% Hydrogen Peroxide How Dependent Variable will be Measured: Hydrogen Peroxide will be used in every experiment, just with different test tubes. The amount of Hydrogen Peroxide in the mixing table is the amount that will be added to each test tube.
Susquehanna River Lab Report
867 Words | 4 PagesOn the trip with SWEEP the health of the Susquehanna River was studied. In order to do that, chemical test, biological tests, and physical observations were made. Chemical testing showed the more scientific side of water quality, such as the amount of nitrates, phosphates, the pH values, temperature, dissolved oxygen, and turbidity. Searching for macroinvertebrates was the biological testing. Certain macroinvertebrates and the quantity found determines how healthy the stream is.

An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.

Radish Plant Experiment
924 Words | 4 PagesAbstract: The purpose of this experiment was to determine whether the amount of topsoil would influence the growth of radish plants. It was hypothesized that if the amount of topsoil increased by 50% would increase because topsoil contains the essential nutrients which are required for proper plant growth. The principle findings indicated that a medium amount of topsoil is ideal for plant growth as the radish plant potted in 50 ml of topsoil experienced the most growth in comparison to the radish plants potted either in 25 ml or 200 ml of topsoil. Introduction: A healthy layer of topsoil comprises of a mixture of clay, sand, silt, and humus that supply the plants with vital nutrients, such as nitrogen, phosphorus, potassium and other necessary
Argumentative Essay On Organic Food
1351 Words | 6 PagesThis type of organic food that is popular among many people is produced on organic farms. Farms belonging to this group foster recycling, speak for promotion of ecological balance concept and represent the direction of conserving environment. The process of growing organic food implies refusal from use of synthetic pesticides as well as other chemical stuff that increases fertility. According to the Food Marketing Institute, “Organic livestock must have access to the outdoors and be given no antibiotics or growth hormones” (Natural And Organic Foods).

Biochemical Test Lab Report
1371 Words | 6 PagesBiochemical tests are the tests used for the identification of bacterial species based on the differences in the biochemical activities of different bacteria. Bacterial physiology differs from one species to the other. These differences in carbohydrate metabolism, protein metabolism, fat metabolism, production of certain enzymes and ability to utilize a particular compound help them to be identified by the biochemical tests. Gram’s stain was originally devised by histologist Hans Christian Gram in 1884. Gram-positive bacteria stain purple, while Gram-negative bacteria stain pink when subjected to Gram staining.
Inorganic Fertilizer Literature Review
2084 Words | 9 PagesFertilizers remove the nutrients of the soil damaging the soil and the local environment and after being mixed with the soil, gradually reduce the fertility of the soil. In the study of (Southland) using fertilizers consists of substances and chemicals like methane, carbon dioxide, ammonia, and nitrogen, the emission of which has contributed to a great extent in the quantity of greenhouse gases present in the environment. These facts are alarming and a serious step needs to be taken as soon as possible to avoid more severe consequences. This in turn is leading to global warming and weather changes. The use of fertilizers for growth and cultivation is keeping our stomach filled for now, but then if things keep on progressing the way they are, it won’t take long to see the times where there is lack of food, water, and health.
