The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

Osmosis in Red Onion Cells By: Youssef Gharib Brief Description of Osmosis in Red Onion cells: Osmosis is the diffusion of water from an area of low concentration to an area of high concentration across a semi-permeable membrane. The purpose of this lab is to compare the three different types of solutions affect on the relative size of the vacuole to the cell‚ the outer membrane of onion red cells (tunics) are used to figure out the different types. In the red onion you can see effects promptly

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

Isolation and Identification of Staphylococcus aureus and epidermidis Wendy Heck Bio 175: General Microbiology Fall 2012-11-21 Staphylococcus aureus is the most pathogenic for humans and Staphylococcus epidermidis is part of the normal flora and is of low pathogenicity. Staphylococcus epidermidis and Staphylococcus aureus are two medically important species of bacteria. A culture from the nose and throat was taken to perform whether or not Staphylococcus epidermidis or Staphylococcus aureus

EXTRACTION OF TRIMYRISTIN FROM NUTMEG: Paul I. PURPOSE: The purpose of this experiment was to illustrate the extraction of a solid natural product from its natural source by partition with the aid of an organic solvent. Extraction is the process by which a compound or mixtures of‚ is transferred by separation from one phase into another. In this case‚ the major triglyceride contains a single fatty acid identified as myristic acid. It is a substituent

Name: Nikia Martinez Class: Biology 240L L3-1201 Assignment: Electrocardiography Lab Report Due: April 3rd 2012 Professor: Dr. B. Schoffstall Introduction In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary

the percent yield by dividing the expected yield‚ the amount of product that should be produced based on your stoichiometric calculations‚ by the actual yield‚ the amount of product that is experimentally obtained from a chemical reaction. In this lab‚ I have determined the reaction for mixing two reactants together; I measured out 0.005 moles of each reactant‚ lead (II) nitrate and potassium chromate. I dissolved‚ mixed‚ and made them react to make products; I compared the mass of the two reactants
