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

Title: Microorganisms are everywhere. Tara Brady Dt201 Objectives: In this experiment‚ my aim is to prove that microorganisms are present everywhere and that nowhere in our everyday lives is free from bacteria. I expect this to be the case as even germicide soaps do not kill all bacteria present on our skin; likewise household cleaning products are incapable of killing all microorganisms present. I am doing his experiment to verify the concept that microorganisms are everywhere and I most certainly

Lab One: Laboratory Techniques and Measurements Abstract The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10‚ and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data

Introduction: The technique used in this experiment is recrystallization. Recrystallization is an often-used method for purifying solids. Recrystallization works by taking advantage of the different solubility properties of compounds‚ and allows impurities to be removed from crude solids. Performing a recrystallization is usually a straightforward task. First‚ you add a small amount of solvent to the impure compound in a flask‚ and heat the contents until all the material has dissolved. Then‚ you

Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study. This study allows the student to exercise their ability to use and understand sterile techniques‚ transmission‚ and prevention of microorganisms. Materials provided by the instructor‚ including an agar plate and cotton swab were used to collect

University of Texas at Tyler Lab 3C: Purification of L-Lactate Dehydrogenase By Affinity Chromatography on Cibacron-Blue Sepharose David Alexander 10-15-2014 Dr. Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally

et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light
