Experiment #3 — observing the Moon’s Phases Objective To determine the relationship of the Earth, Moon and Sun as the Moon orbits the Earth.
Introduction
In astronomy, determining the relative position of the moon, the sun and the Earth requires the study of phases of the moon at different days of observation. In which case, complete cycle through the phases called lunar month gives the synodic month, always around 29 days. The lab report studied these phenomena to realize moon’s position in relation to the other two.
Procedure
The moon was observed and a dark part was shaded to show how the moon would look like at each point from the Earth. Each phases of the moon was labeled and presented in diagram forms as shown in the result section.
Results
Figure 1: my position, moon’s position in relation to the Earth and the sun
The arrow in the diagram shows my movement as I focused on the moon at each position. From the diagram above, shape of the moon were focused in each phase:

Conclusion
The experiment was successful in meeting the previously stated objective. Different phases of the moon were realized from each day of observation thereby insinuating the position of the moon in relation to the sun and the Earth. In which case, during the full moon the Earth was observed to be in the middle while during the new moon, the moon was observed to be between the two. Read More

...? Lab 4: Enzyme Experiment Effect of enzyme concentration Data Table Effect of enzyme concentration on the production of gas Response to Question 1 Enzyme-Catalase produced by the yeast Substrate-Hydrogen peroxide Response to Question 2 The rate of reaction in tube 1 was rapid followed by tube 2 and in tube 3 it was the slowest. This difference was because of the differences in the concentration of yeast cells that produces catalase enzyme directly proportion to the amount in each tube. The higher the concentration of catalase enzyme the higher the rate of reaction and vice versa. In other words the more yeast put in the Hydrogen Peroxide the more violent the reaction; therefore, giving off more oxygen. This is because of the reaction...

...? Psychology A number of researchers have tried to expound the idea behind the working of the memory. Uncovering the principles involved in the spatial information and the working memory has been the primary goal of most of the psychologist and neurologist (Hommel, Musseler, Aschersleben & Prinz, 2001). Spatial information entails those form of information that human being encounters in his day-to-day activities. The research done by Humphreys & Riddoch (1992) reveals that the way the spatial information are perceived and perceptually organized may shape the emerging cognitive representation some time before processes of memory storage or retrieval come into play. Such information is acquired through senses. A number of theories... Psychology ...

...? pH Values of Common Household Items Compare and contrast acids and bases in terms of their H+ and OH- ion concentrations. All substances can be classified into acids, bases and neutral depending on their ionization trends when dissolved in water. Acids produce a greater number of H+ ions which can be explained by the fact that acids give up a H+ ion on reaction with water forming an H3O+ ion. These ions cause the litmus to turn red. Greater the concentration of H+ ions, stronger is the acid signified by the pH scale: pH of 1 being the most acidic and 7 being neutral. For bases, number of generated OH- is greater than H+. These, on reaction with water, gain a hydrogen ion leaving behind an OH- ion. Bases cause the litmus to turn... pH Values ...

... Procedure This experiment requires three cuvettes, a spectrophotometer, a graduated cylinder, dye of three differentcolours. The first step is to fill the three cuvettes with red dye, green dye and blue dye with each holding a dye of different colour. The initial concentrations of these dye is 100% at the beginning of the experiment. The cuvettes are then placed into a spectrophotometer. They are oriented in such a way that their smooth sides lining face the light source to enable easy penetration of light through them. Multiple trials were then performed because the spectrophotometer can only measure one sample at a time. In order to ensure accuracy and precision, it was necessary to re-calibrate the spectrophotometer three... Procedure...

Discuss the resources which were most significant to them. The majority of the origins of people in Michigan are Native American; which arrived between 12,000 and 14,000 years ago. These Paleo-Indian peoples traveled from Alaska and Asia across the Bering Straits. The most important resources to these peoples were the herds of caribou, mastodons, and mammoths; they relied upon these animals for food and furs for clothing.

...Discussion In the test for the engine parameters, it was found out that the temperature changes for ambient temperature, and fuel in the engine increased with time. On the other hand, the temperatures for oil output, the exhaust, cooler in the engine, the cooler output and the oil input decrease with time. The results recorded were used to calculate for the derived values such that torque was obtained as 72.7 N/M and ranges between 72.1 N/M - 72.7 N/M, the brake power was obtained to be in the range 40987.46667 KW - 8370.193333 KW, the brake thermal efficiency was calculated to be 32% and ranges between 23.4 % - 32.4 %. Finally the volumetric efficiency was found to be 60%. It is important to point out that the torque... In the test for the...

... Lab It is crucial to familiarize with various concepts before conducting lab experiments. One of the importantconcepts for this experiment is solubility, which can be defined as the ability of a substance (solute) to dissolve in another (solvent) (Bauer et al. 216). The estimation maximum quantity of a substance that dissolves in a solvent at equilibrium yields solubility (Brown et al. 120). Qualitative analysis is done to identify elements in the sample used for the experiment. For this experiment, qualitative analysis was employed to establish whether or not a precipitate would form upon adding some acids and bases. A flow chart was used to distinguish between cations in the resultant solution. A flow chart refers to a diagrammatic...

...values showing the absorbance of a given wavelength, it can be stated that the concentration is directly proportional to the absorbance, which initially was proved by Beer-Lambert Law(Bauer et al.110). The objective of this lab experiment was establishing the percentage Mass of Copper (II) ion (Cu2+) in a sample of ore by using Calorimetry technique. The percentage of Mass can be defined as the mass of a definite element over the total mass of all elements multiplied by 100%(Brown et al.85).Through establishment of a standard for the copper nitrate compound and utilizing the knowledge of Beer-Lambert Law, the % mass of the copper in the ore was attained. 2.
