Physics Lab report Aammar Paracha Section MX Feb 6th 2015 OPTICS Abstract: This experiment revolves around using light rays and lenses. The experiment also discusses different properties of light rays. This experiment uses different lenses and measurements to produce images and observes different techniques to obtain the image position. Question and Answers: 1. Use your data to verify the Law of Reflection and then use Snell’s Law to calculate

’Neil 2002). The particular conditions that had to exist for this to apply were that the population had no mutation‚ had no natural selection‚ was a large population‚ had only random mating‚ and had no migration. For the cases to follow later in the lab‚ Cases 1 and 2 exemplify Hardy-Weinberg conditions. All of the others either have selection or not enough members in the population‚ which will be the most-closely observed

higher osmosis will perform within the plant cell. When the molecules are heated‚ they start to move faster‚ causing osmosis to perform faster than at a neutral temperature. Temperature is just one of the many factors that can affect osmosis‚ such as‚ the pressure (the less pressure‚ the molecules will move leisurely over the gradient) of molecules and the surface area of the molecules (the smaller the surface area‚ the more the molecules are delimited to move across the gradient‚ causing osmosis

Photosynthesis Background Do you know what is the most important process that sustains life? Photosynthesis‚ that is the correct answer! Photosynthesis‚ is known as the process to produce plant food. But‚ how does is the life exist on the planet we call our home‚ Earth? Photosynthesis is a process that we know that allows water‚ carbon dioxide‚ and some mineral salts along with the light from the sun to make glucose (sugar). During the process‚ the root sytem of the plant takes in elements

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

The purpose of module E is to learn several DNA techniques in the lab including DNA purification with solubility and absorption‚ plasmid transfection of E.coli‚ colony screening by PCR and quantitative PCR. First part of the experiment E1 show the purification method of DNA through solubility. E. coli lysate mixed organic solvents to purify the DNA present in solution. First‚ the lysate was mixed with phenol/chloroform‚ then vortexed‚ and centrifuged. We extracted the aqueous layer and combined

1. Introduction Microscopy is an essential technique not only in cell biology but natural science as a whole. We compared different types of microscopic techniques ‚ according to the specimen used and the scope of the experiment. Two specimens‚ stained and unstained‚ containing CHO cells‚ were prepared‚ examined and analyzed under the microscope using bright field (HF)‚ dark field (DF) and phase contrast (PH) settings. In addition‚ the four phases of cell division cycle were estimated.. Bright

The purpose of this experiment was to determine the weight percentage of copper in brass. This was achieved by performing a redox titration known as iodometry. Copper‚ which was obtained from the brass‚ was used to react with iodide to produce iodine. Iodine was then titrated with thiosulfate. In this experiment‚ the amount of titrant dispensed correlates with the amount of copper; therefore‚ the amount of copper in brass was calculated by using the data recorded. In this experiment‚ the analyte

Impurity Lab Report Aim: To find out the difference of the boiling point and melting point when adding impurity (salt) to water. Diagram: Method: 1.Set up the apparatus as shown in the diagram 2. Get a known amount of ice in the beaker (half full)‚ and a known amount of salt in another beaker 3. Measure the temperature (melting point) of the ice without adding any impurity (salt). 4. Measure the temperature (melting point) of the ice after adding the salt into the beaker. 5. Heat up
