LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger up to the pulse transducer sensor. Using the chart 5 program on the lab computer the participant’s

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

Kiley O’Toole Lab Report 3 Purpose The purpose of this lab was to uncover the number of layers of zinc atoms around a piece of galvanized iron. This was done by pouring the hydrochloric acid onto the galvanized iron‚ thus removing the zinc from the piece of metal. Laboratory Procedure 1. Measured and recorded the mass of a piece of galvanized iron using a centigram balance and a ruler 2. Measured and recorded the length and width of the galvanized iron using the ruler 3. Put the

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &
