Title: Observation of Macroscopic Chemical Changes‚ Alice Kimbrell‚ Chemistry 101-DS01:74589‚ 5/31/2013. Purpose: In this lab‚ I will observe macroscopic changes that occur when mixing together certain chemicals and household cleaners. The mixing of the chemicals provided with each other and with acid/base indicators demonstrates how matter can change‚ and how chemistry can be seen with the naked eye. By mixing household cleaners with an acid/base indicator I hope to demonstrate how these

2012 The Microscope Introduction: The purpose of a microscope is to see either enlarge images of small objects and or make seen what is invisible to the naked eye. We have two types of microscopes available in the lab. The dissecting microscope is designed to study objects in three dimensions at low magnification. The compound microscope is used for examining small or thinly sliced sections of objects under magnification that is higher than the dissecting microscope. In this lab we will learn

METHODS In this experiment‚ plasmid lux and a control plasmid (pUC18) will be introduced into E. coli by transformation. There are four basic steps to the procedure; Preparation of competent cells (These steps should be performed by the instructor.) 1. Place a vial of CaCl2 solution and the tube of E. coli in the ice bath. 2. Using a sterile pipet‚ transfer 590µL CaCl2 solution to the tube containing 50µL of the bacteria. 3. Tap the vial with the tip of your index finger to mix the solution. 4. Incubate

Molecular Techniques - Lab #1 BIO 349 Lab Report #1 Microscopy and Staining Abstract The primary focus of this lab was on microscopy and simple stains. Microscopy that was used were magnification‚ slide preparation‚ and staining. Methylene blue‚ a simple staining component‚ was used to stain the slide in order to see the different microbes and determine their cellular shape. Introduction The purpose of this lab was to become familiar with the light microscope and how to accurately

genetic alteration of a cell‚ resulting from the intake of exogenous genetic material through the surrounding cell membrane. The purpose of this lab was to determine transformation of bacteria by testing the effect of P Vib plasmid of E. coli MM294‚ and how the color of the E. coli bacteria changes. In this lab‚ two small test tubes were given calcium chloride‚ E. coli MM294‚ and one of the tubes also received the plasmid P Vib. The test tubes were then placed in ice‚ heat shocked‚ and then a small amount
