Sierra Gardner Professor Broxton European History 11/5/2014 Galileo Galilei and the Scientific Revolution Galileo Galilei‚ also referred to as the father of modern science‚ a man far beyond his years‚ only to become one of the world’s most renowned physicist‚ astronomer‚ and philosopher. An abundance of titles for a man who was born in a society of people who still believed that the heaver an object was the faster it would reach the ground‚ a world not yet in tune with modern science. Galileo’s

INTRODUCTION TO SCIENTIFIC TERMINOLOGY The purpose of this document is to introduce root words and their definitions. These words play a vital role in Biology because many scientific terms are based on these words. Because these root words are Greek or Latin in origin‚ their meanings have remained consistent throughout time. By becoming familiar with root words and their definitions you can determine general meanings of many terms by simply applying these root word definitions. For example‚ the

the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed reaction? Materials

pH on Enzyme Activity Athenaa Jeyachandran Mr.Menes Course Code January 21st‚ 2013 The Effect on Enzyme Activity Due to Temperatures Purpose: The purpose of this lab experiment is to examine how different temperatures affect enzyme activity using hydrogen peroxide. Hypothesis: My hypothesis for this experiment is that temperatures near body temperature is when enzyme activity will be at its highest. I believe this will occur because in our body‚ enzymes are very

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24‚ 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in

Biology 123 Professor K Title: Scientific Investigation of the Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What

An experiment was run to determine which enzyme (pectinase‚ and cellulase or combinations of the two enzymes) maximizes juice production and would be most cost effective. The proposed hypothesis was if the enzyme‚ pectinase‚ is added to apple juice‚ then the more juice will be extracted than if cellulase were added because pectinase holds the cell wall together and if it is separated apart from each other‚ then the more juice would be able to flow out. The experimental data show that during the ten
