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

through a deferentially permeable membrane depending on the concentration differences. We used PhysioEx software to examine diffusion. In these experiments we used different sized membranes as well as NaCl‚ urea‚ glucose‚ albumin‚ powdered charcoal‚ and KCl. The step by step process was used by the software so that we could see the different kinds of reactions. According to the data found‚ we found that with high molecular weight compounds are too large to penetrate the molecular weight cut off pores

’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

Raquel Johnson October 19‚ 2014 Solids: Recrystallization and Melting Points Organic Chemistry 2423 Lab Report: Recrystallization Abstract: The purpose of this lab was to purify an unknown compound by recrystallization. Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point. An unknown compound was recrystallized from hot water to produce 0.99 grams (67% recovery)

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

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

Lab Report Procedure 6.1: Perform Benedict’s test for reducing sugars. Introduction: Benedict’s tests allows for the detection of the presence of reducing sugars. All monosaccharides are reducing sugars since all of them have active carbonyl group. Some disaccharides that are exposed to a carbonyl group are also reducing sugars but less reactive than monosaccharides. By mixing the sugar solution with Benedict’s solution and heating them‚ a redox reaction will occur. The copper (II) sulphate

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart‚ because there is more pressure closer to the heart. In contrast‚ one’s pulse is quieter the further away it is measured from the heart‚ because there is less pressure the further the distance

Separation of the Components of a Mixture General Chemistry 1 (Chem 101)‚ ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations
