    Salinity ExperimentAimTo determine a method of measuring a soil sample's salinity level in order to measure 3 samples's salinity level. Hypothesis I think that by running a current through a salt solution and measuring the resultant amperage, a pattern in the recordings will help find a soil sample's salinity level. Variables Controlled - Amount of solution (100 mL), supplied voltage (4 V), amount of soil (50 gm) & water (150 mL) in soil sample's solution. Independent - Amps recorded by ammeter....

    INSTRUCTIONS FOR TAKING A SOIL SAMPLE These instructions are for taking a soil sample from a yard, pasture, or any other piece of land. The purpose of a soil sample is to determine the pH of the soil. These instructions give a simple step by step procedure that anyone can do. Anyone who is trying to grow something can use a soil sample to help them get the best growth for whatever they are planting. The reason for needing to read these instructions is so that a proper sample will be taken so you...

    Speech Analysis- The language sample that was analyzed was taken from a child 4 years and 11 months old. The recording took place in the child s bedroom, and I was the only other person present. The sample analysis is based on approximately 15 minutes of speech or 50 utterances. After transcribing the sample, I first calculated the Type Token Ratio (TTR). The Type Token Ratio measures the child s lexical diversity. It is calculated by dividing the total number of different words by the total nu...

    DNA and Restriction Enzyme Interaction: Identification Of An Unknown Plasmid Abstract The fundamental purpose of these experiments is to research the interaction between DNA molecules and restriction enzymes. Two different experiments are performed. In the first experiment, two restriction enzymes, Hind III and Bam H 1 interact with an unknown plasmid and the resulting DNA fragments are separated through electrophoresis. Lambda sample is used to create a standard curve, and through it, the sizes...

    Analytical Chemistry Analytical Chemistry is the branch of chemistry principally concerned with determining the chemical composition of materials, which may be solids, liquids, gases, pure elements, compounds, or complex mixtures. In addition, chemical analysis can characterize materials but determining their molecular structures and measuring such physical properties as pH, color, and solubility. Wet analysis involves the studying of substances that have been submerged in a solution and microan...

    Distillation Andrea PausmaOctober 1, 2001 I. Introduction The process of distillation has been used by humans for years to create alcoholic beverages. Distillation is the process of boiling a pair of liquids with different boiling points and then condensing the vapors above the boiling liquid in an attempt to separate them. One might suspect that the mixed two liquids of different boiling points could be separated simply by raising the temperature to the lower boiling point of the two liquids. H...

    1 Sampling Methods When surveying, for any purpose, it is important to recognise that the results are only as representative as the survey subjects (the sample), and as such much academic research has been performed in to techniques for selection, broadly placing them in one of two categories - probability sampling and non-probability sampling. In short, with probability sampling the participants are selected by chance. There are dozens of methods of selecting members, using a variety of mathema...

    Many businesses are Product Orientated. This means that they design and make a product, and then try and convince consumers to buy it. Business can also be "Market Orientated." This is where they try to find out what consumers want before making the final product. Finding out about what consumers want and need, and what makes them buy, is called "Market Research." Businesses which are mainly product orientated risk spending a large amount of resources launching a product which proves to be a fai...

  • Conductivity Of Water Time That The Soil

    Abstract This experiment was designed to explore nature of water as it pertains to conductivity. It can be shown that the conductivity of a substance is directly related to the amount of dissolved salts in the substance, as salts are ions. One contributor to water conductivity, therefore, is soil, as it contains many minerals and other substances which, when dissolved in water, form ions. The experiment focused on the effect of three variables on water conductivity: the type of soil, the amount ...

    Summary: Aluminum and steel were tested over three different temperature readings. One of each sample was put into an oven at about 245^0 F, a bath of ice water and finally in dry ice at about -30^0 F. After the metal sample's temperature was changed by exposure to each external stimulus, we proceeded to break each sample. The Impact Test Machine was used to break the steel sample. The CIM-24 was used to break the aluminum sample. Procedure: The pendulum was raised up to the top position just pr...
