proportional relationship between the square of the period of oscillations to the length of the pendulum.Sources of error for this procedure included precision in both length and time measurement tools‚ reaction time of the stopwatch holder‚ and the accuracy of the stopwatch with respect to the lab atomic clock. The final result of g takes into account the correction for the error introduced using the approximation. There are opportunities to correct for the effects of mass distribution‚ air buoyancy

Abstract: The main objective of this Lab‚ is to experiment with stoichiometric measurements‚ since it is one of the most important subjects in chemistry. In addition‚ stoichiometric measurement is widely used in chemistry‚ because it indicates the proportion of mass in which various substances react. By examining one specific example of stoichiometric determination‚ which is: “Stoichiometry and limiting reacting”‚ we found out the different mass proportions in which substance react. In this case

Microbiology-2460 Lab-003 March 31‚2008 Lab Report-Escherichia coli Abstract The purpose for this lab report was to identify and inform of an unknown bacteria that has been causing a patient to have lower abdominal and pelvic pain. To obtain the identification of this unknown bacterium‚ several biochemical tests needed to be performed in order to prescribe the correct medication to treat and cure the symptoms. Introduction In a lab today‚ I am to identify an unknown bacterium that is

factors of a chemical reaction affect the rate of reaction. This experiment focused on how temperature affects the rate of reaction for the reaction of alka-seltzer and water. The rate of a reaction is a value calculated to figure out how fast a chemical reaction occurs. There are three factors that can be changed that will affect the rate of a chemical reaction: surface area‚ concentration‚ and temperature. Temperature specifically affects the rate of a chemical reaction‚ because when the temperature

Lab Report Janice Chisholm SCI207: Dependence of Man on the Environment Instructor: Lee Ott April 28‚ 2013 1. What patterns do you observe on the information table 4? While observing the information in table 4‚ it appears that the number of fish changes from time to time and the oxygen increases and / or decreases when this occurs. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured
