While others were obtained away from the river, the main goal being to expose the students to experience field work, and environmental science Hypothesis that we formulated included, most soils found in wabashiki river are clay soils, the nearer the soil is on the river the higher smoother the texture, texture of soils depicts its components, the soil pH is mostly constant Every group having the relevant materials embarked into obtaining the samples for use and documentation. Each and every person within the group was expected to come up with his own samples each. Some from near the river and further away from the river; the sampling site was obtained after the purpose of the study was established thus no major sampling technique was put in place (Easton p135). The study was to take place along the river at different coordinates. The analysis of a soil sample to determine its nutrients and the contents contaminated and also other characteristics like the ph. Level. There were various soils testing strategies put in place some were to be done in the field so that one could obtain results as soon, as the soil was from its natural flora, and fauna to avoid defects due to transport handling and storage. Some of the testing done on the field includes crushing, feeling the texture acidity porosity trough exposure to water. The soils were obtained from flat grassy ground, and also from a hilly part near the river the following was observed, Both soils had the same average period of time, i.e. 10yrs though thee color varied as the soils obtained from the grassy flat area had a less color value than those obtained from near the river that had a higher color value. Although the two ended up having the color Chroma values of two each, the soil that was obtained from the grassy flat area was established as a sandy loam soil after cross examination. While the soil obtained from near the river was established as silty clay loam soil. Each collected sample was labeled accordingly comprising the following; group name, student initials, GPS coordinates, section number, date and sample number. Members of the group were to meet and carryout various tests within the laboratory this is where the tests for nitrogen, phosphorus, and potassium were done. The samples were to be divided, and parts of them were dried for the purpose of carrying out tests in total more 10 samples were collected in my group five from near the river, and the other five away from the river this was executed such that each sample came from different coordinates so as to obtain well distributed samples (Easton p 220). After the tests were conducted the following was observed, the soils extracted from near the river had low contents of phosphorous while those obtained from near the river had relatively high quantities of phosphorus. All the samples tested had very low quantities of nitrogen in them whether they were obtained from further away or near the river. The ph. of all the samples obtained was neutral at 7 points this showed that despite the fact that the samples were obtained from different places none, showed any basic or acidic characteristic. From the results, it was also noted that the all the samples obtained from the two areas, had very high contents of potassium. The tests conducted were fundamental in depicting the various characteristics of each and every sample obtained. The soil texture of the samples obtained varied. z sandy loam soil color sheet 10 color value 3 color chroma 2 ph 7 The soil texture is known as the relative composition of various soil particles size fractions in soil. ...Download file to see next pagesRead More

...?Lidia M. Lujan Lab report W14s1 Debate on Global Warming: Scientific Basis Global warming refers to the increase in the temperature of the earth's surface and troposphere. The term global warming is used interchangeably with “climate change,” referring to the other climatic changes aside from or due to increased global temperatures. The change in temperature is attributed directly due to increased in emission of greenhouse gases, largest concentration of which is carbon dioxide. The increased emission arises from human activities in the transport and energy sector (US Environmental Protection Agency). Other human activities like clearing of land, deforestation, and desertification that abet temperature...

The niche of an organism is the overall interactions of an organism with other organisms and its range of needs (Properties of microbes). 2. Organisms might compete for food, light, and space. 3. Evolution is the process of gradual development of organisms from simple structures to intricate forms over time. Competition affects the process of evolution in that the organism that is able to compete favorably for the available resources survives and continues to thrive, whereas the organism that cannot compete favorably dies and becomes extinct.

...Lab report Prediction of the Maximum Height Travelled By a Model Rocket The determination of rocket field is useful when in the quest for determining how high a rocket flies, at a given moment. In this lab, the major objective was to predict how high a rocket model could fly once launched. This involved acquiring a model rocket, then launching it to determine the figures for the various variables. Another related objective was to apply equations for basic projectile motion in determining how high a rocket can fly. Since launching the model rocket, this is considered a projectile motion influenced by height of launch pad, gravity and velocity imparted by the engine. Consequently, there...

...while in the case of measurement 2; it is 1.59m/s. 3 This lab experiment is relevant to many scenarios in life. When an object travels in the circular motion, its speed is constant which implies that the magnitude of the objects velocity is not changing while the direction changes. On a practical sense, the activity of driving around a curvy road is equivalent to this lab experiment. For a constant speed, tighter curves tend to generate a greater centripetal acceleration provided by the friction between the tires and the road. This can be described as follows: for steady speed, the equation of centripetal force has it that acceleration is indirectly proportional to the radii of the curve. When a car...

.... A normal pendulum with a few modifications can be used to achieve similar objectives. In this case, a zero position for the pendulum is identified. Since many labs are done on tabletops, the table top is assigned to be the zero height (mean) position. If the tabletop is designated the zero position, then the PE of an object is dependent on its relative height from the tabletop. Therefore, by obtaining the mass of the pendulum and its relative height from the table top, the gravitational potential energy can be calculated follow: PE = mass x relative height x Gravitational pull = mgh 2. As a car goes over a rough road or bumps, the spring in its shock-absorber setup is compressed, but the...
