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

Joshua Berkebile 8-26-10 1st period Density Lab The purpose of this lab was to find the mass‚ the length‚ the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object

AP Bio Block B Photosynthesis Lab 12/6/12 Introduction: Photosynthesis is affected by light intensity‚ water‚ and temperature. Plants grow more abundantly because the weather is warm. Carbon Dioxide given off by animals is consumed by plants that replace the oxygen animals take it. Experimentation will help understanding how plants are vital because of the oxygen they release. If leaf disks in the experiment release oxygen‚ they will undergo photosynthesis and float. If

irregularly shaped objects‚ liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic

Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

I had # 8 organism‚ Bacillus subtilis. Bacillus subtilis is a Gram-positive bacteria‚ rod-shaped and catalase positive. In order to figure out what is my unknown organism for this assignment‚ I had to perform series of tests. First was the glucose‚ lactose‚ and sucrose test. Through these three tests‚ I was able to detect the ability of the microorganism to ferment a specific carbohydrate. Fermentation reactions are observed by the color change in pH. In class‚ we used phenol red as the pH indicator
