Lab Report 1: Natural Selection Introduction: In today’s lab we learned how natural selection and survival of the fitness took place in Darwin theory by testing it out with four different utensils which were Spoon‚ Fork‚ chopstick‚ and clothespin which represent the four different types of bird beaks. Our goal was to see which one utensil ( bird beak) would outcome the other four utensil ( bird beak) by being able to survive with the limit amount of food‚ the environmental chances‚ and see who

Timothy Johns Christian Howard Wan Huang 10/18/12 Flame Test Lab Introduction Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by atoms and molecules. These studies are very helpful in determining an unknown element‚ given the fact that all elements burn a different color. The flame colors vary because of the different amounts of energy the elements give off. This lab is made for the learner to determine the identity of two unknown elements. Hypothesis If

1. Introduction The Jominy end-quench test is a technique that has the ability to harden the steel by quenching. It is an essential feature of materials that determine the material’s selection for particular applications. The different types of steels and alloys that are used for hardening in an industry are done by this test and considering that this test is a standardised experiment [1]. 1.1 Aim The specimens that are used in this test are normalized in accordance with the standards. The purpose

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

Lab #4: The Immune System Purpose: The purpose of this lab was to perform and understand the procedures of conducting an ELISA test to determine whether a particular antibody is present in a patient’s blood sample through a virtual simulation. Hypothesis: If I successfully complete this lab‚ I will then understand how to perform an ELISA test‚ the purpose an ELISA test‚ and also how to interpret the results of this test.

Unknown #11: Citrobacter freundii Tryptic Soy Agar Test (TSA): TSA is a basic medium that is most similar to nutrient agar. The agar contains carbon‚ nitrogen‚ sodium chloride‚ and agar. This allows for the growth of a large variety of microorganisms to grow and ferment in the medium. Mannitol Salt Agar (MSA): MSA is a selective and differential medium that favors the growth of salt loving organisms. It is commonly used to distinguish the different species of Staphylococci. If an organism ferments

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

Lab Report Janice Chisholm SCI207: Dependence of Man on the Environment Instructor: Lee Ott April 28‚ 2013 1. What patterns do you observe on the information table 4? While observing the information in table 4‚ it appears that the number of fish changes from time to time and the oxygen increases and / or decreases when this occurs. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?
