Edward Dickson CHE101 DS-01 Experiment Date 7/21/2013 Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

If these variables were not to be held constant than the findings of this experiment would be meaningless because there would be no way of desiring if the independent variable was the cause of the changes which were recorded In this experiment‚

learned so far in the microbiology laboratory class for the identification of unknown bacteria. The identification process can be completed with a series of deferential stains and biochemical tests. Creating a dichotomous key helps to limit the amount of biochemical tests done on an unknown organism and by observation and recording of data the unknown organism can be found. Materials and Methods The procedure for all tests performed was taken from Leboffe and Pierce’s Microbiology: Laboratory Theory

Microbiology is the study of living organisms that are too small to be clearly seen by the unaided eye. The science of Microbiology dates back only to 200 years‚ yet the recent discovery of Mycobacterium tuberculosis DNA in 3000 year old Egyptian mummy reminds us that microbes have been around for much longer. Infact‚ Bacterial ancestors were the first living things to appear on Earth. The First observations: One of the most important discoveries in the history of Microbiology occurred in 1665

Experiment 1 Laboratory Techniques and Measurements Purpose: To determine measurements of different items that vary from solids to liquids and be able convert those values to other SI units of measurement. Procedure: I used a variety of scientific tools such as; a ruler‚ beaker‚ graduated cylinder‚ volumetric flask‚ thermometer‚ burner‚ and digital scale to find unknown values of measurements for each of the indicated

Microbiology is the study of microorganisms which must be viewed with the aid of a microscope or electron microscope. The importance of microbiology includes: used in biomedical research‚ creation of medicines‚ environmental applications and new research tools. Disease causing organisms include: protists‚ bacteria‚ viruses and other microorganisms. Bacteria are important for fixing N2 in a usable form for plants. Bacteria and some fungi are important in decomposition and recycling

What Is Microbiology? Microbiology is the study (logy) of very small (micro) living (bio) things. Microbiology is the study of microorganisms. These "bugs" include: bacteria (that’s the Latin plural for bacterium); viruses (that’s the non-Latin plural for virus - virii sounds weird‚ so I don’t say it); and‚ fungi (that’s the Latin plural for fungus - which by now you have guessed‚ or already knew‚ and may not be all that interested to know‚ anyway). Microbiology is actually made up of several
