The temperature of water was determined by a thermometer. 1 cm stripped ends of the wires was hooked into the input posts on the back of the impendence converter. Lab tutor module was started after. B. Baseline heart rate The top of the container was covered with foil and the animal was allowed to sit quietly for 10 min. The trace was examined by pressing start. After that the baseline or the controlled

Science Lab on Electromagnets By Caitlin Hendriks Factors that Affect the Strength of an Electromagnet Purpose: To test how two different factors‚ the number of loops and the current intensity‚ affect the strength of the magnetic field of an electromagnet. Materials: Power pack‚ 4 connecting wires‚ switch‚ ammeter‚ paperclips‚ iron nail‚ copper wire. PART A: TESTING THE NUMBER OF LOOPS Procedure: 1. Create an

Joshua Berkebile 8-26-10 1st period Density Lab The purpose of this lab was to find the mass‚ the length‚ the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;

The Determination of the Concentration of Hard Water Ions by the Titration of EDTA By Hannah Denby Lab partners: Heidi Kiziah‚ Leonie Hamel University of Central Florida‚ CHM 2046L December 3rd‚ 2015 Abstract. The “hardness” of water is a common dilemma attributed by high concentrations of metals such as calcium and magnesium. This is a result of the properties of water; because it is a good solvent‚ impurities are easily dissolved. As water moves through soil and rock‚ it dissolves minute amounts

LABORATORY REPORT ENGINEERING SCIENCE – ENSC 1005 LECTURER: Asha Sooknanan It is important that a student not only learns the physical concepts discussed in a laboratory exercise‚ but that the student also learns how to communicate those ideas effectively. In a technical lab report‚ the results will often be read by engineers‚ engineering technologies‚ and other scientists‚ but also by people in industry who may not have significant training in physics. Due to this fact‚ a technical lab report

Organismic Lab Lab1- Dichotomous Key Introduction A dichotomous key is a series of paired statements or questions that are used to categorize organisms with their similarities in characteristics and or structure. The word dichotomous comes from two Greek words that translate to “divided in two parts.” In a Dichotomous key each step has two choices: whether a particular characteristic is present or absent. The questions

Transformation Lab Report Introduction Transformation is the transfers of virulence from one cell to another‚ through the transferring of genetic material. It was originally postulated in 1928 through the works of Federick Griffith‚ a British microbiologist. Griffith observed that the mutant form‚ non-virulent form‚ of the bacteria Streptococcus Pnumoniae could be transformed into the normal‚ virulent form‚ when injected into mice along with heat killed normal forms. He concluded that somehow
