Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Before one can begin the lab‚ he/she must make a prediction about what gene the trait one are analyzing is on. The trait can either be sex-linked‚ or autosomal. To begin the lab‚ one must acquire a sample of flies to cross. These flies should be placed in a tube with an easily removable foam stopper. Use the flynap to knock out the fruit flies‚ and pour them out of the tube into a petri dish. Then place the petri dish on a stereomicroscope‚ and begin using a paintbrush to sort the flies by gender

6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering‚ Environmental Engineering‚ and Petroleum Engineering. “Electrical Filters‚” (Electrical)‚ written by Joe Schmoe‚ is a lab report made by a student at a university. The College Board produced an environmental lab report named‚ “Monitoring Air Quality‚”

Introduction The purpose of this lab was to identify unknown bacteria cultures using various differential tests‚ and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential

SCIE211 Phase 2 Lab Report Title: Speciation Instructions: You will need to write a 1-page lab report using the scientific method to answer the following question: • What would happen if a species within a population were suddenly split into 2 groups by an earthquake that creates a physical barrier like a canyon? When your lab report is complete‚ post it in Submitted Assignment files. Part I: Use the animated time progression of speciation to help you write up your lab report. Part II: Write

grown form ascospore taken from one ascus that reflect crossing over and independent assortment of chromosomes during meiosis. An interesting fact about ascospore arrangements is that there occurs no hybridization‚ and there are peculiar forms of cross over. Ascomycetes can also reproduce asexually by spores called conidia‚ which are spores that are dispersed by wind and are produced at the end of the hyphae. Another interesting fact about Sordaria is the ability to maintain a constant liner order

Discussion The goal of the experiment was to determine what gene or genes are responsible for the white eye phenotype of two strains of Drosophila melanogaster. According the literature‚ the w+ gene is located on the X chromosome at 1.5 genetic map units (1). In addition‚ the st+ and bw+ genes are autosomal and assort independently‚ meaning they are two different genes located on two different chromosomes. It is stated that the bw+ gene is located on the 2R chromosome at 104.5 map units (2)

Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:

that cigarettes release more then 20 carcinogens know to promote lung cancer into your body. (Hecht‚ 2010). When looking at the cilia exposed to cigarette smoke in this lab it is seen that they have been greatly slowed down when compared to the uncontaminated cilia‚ and parts of the cells are covered in tar from the tobacco. For this lab it was hypothesized that smoking will inhibit the ciliary action and lower the quality filter the greater affect will be exhibited by the effected cilia. The prediction

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be
