ENVIRONMENTAL SCIENCE INTRODUCTION The term the environment comes from the French word environ and means everything that surrounds us. Under such a broad umbrella‚ there is a host of ways in which environmental studies can be understood. The Faculty of Environmental Studies defines it as the study of a range of environments‚ from the bodies we live‚ to the physical structures‚ institutions and industries we build‚ to the politics‚ languages and cultural practices we use to communicate‚ and to

Enzyme Activity Lab Objective: To determine the effect of temperature‚ PH and enzyme concentration on catalase activity. Introduction: What is an enzyme and how the enzyme works. Any of a group of complex proteins or conjugated proteins thatare produced by living cells and act as catalysts in specific biochemical reactions. The system in which enzymes work is often referred to as the ’lock and key’ system it’s where the enzyme and the substrate lock together. The substrate then unlocks into

Summer Chacon 12/15/12 Environmental Science P. 5 Ecocolumn Lab Report The purpose of an eco-column lab is to show the similarities between that and a real world. It is a useful tool for learning because you get to create and see your own little world. It is very much like the real world because of the communities of organisms that it consists of‚ along with their physical environment. An eco-column is a closed system. In a closed ecological system‚ any waste products produced by one species

Science Exit Project: Weather Weather itself is the state of the atmosphere at a given time. The weather seems very difficult to predict‚ however it is not as complicated as it seems. After looking at the variables and breaking down the pattern‚ a prediction can be made of the weather. The goal of this experiment is to look at the weather conditions for a given month‚ and then tell what shaped it‚ or what caused a certain variable to change. Procedure/Materials: First‚ I made a chart of the weather

Renewable Energy Wind Abstract We have been harnessing the wind’s energy for hundreds of years. From old Holland to farms in the United States‚ windmills have been used for pumping water and grinding grain. Today‚ the windmill’s modern equivalent‚ a wind turbine‚ can use the wind’s energy to generate electricity. Wind turbines can be used as stand-alone applications‚ such as for pumping water or to help reduce homeowners’ electric bills‚ or they can be connected to a utility power grid

Determination of the concentration of ethanoic acid in commercial vinegar Introduction: The aim of the experiment was to determine the molarity of ethanoic acid in table vinegar by titrating a sample with alkali sodium hydroxide (NaOH) with a known concentration of 0.1molL-1. The equation of the reaction between ethanoic acid and sodium hydroxide is as follows: CH3COOH + NaOH CH3COONa + H2O When the titrations end point is determined and volumes of reactants are measured the concentration
