Title: Enzyme Catalysis of Hydrogen Peroxide by Catalase Problem and Objectives: How do different temperatures and different levels of pH affect the reaction rate of the enzymes in chicken liver? Demonstrate the activity of an enzyme in living tissue‚ observe the effects of changes in temperature and pH on the activity of an enzyme‚ perform analyses for the presence of an enzyme in tissues‚ and analyzing relationships between environmental conditions and enzyme activity. Background: Cells produce

Collision Lab Simulation Purpose: To study elastic and inelastic collisions in one-dimension. Background Information: Momentum: is a measure of mass in motion. It is the product of mass x velocity. Conservation of Momentum: in the absence of external forces‚ such as friction‚ the linear momentum of a system remains constant. Procedure: 1. Open web browser and go to the site: http://phet.colorado.edu 2. Click “play with sims”‚ then “physics”‚ and then “motion” 3. Find the “Collision Lab” 4

Multimedia Graphic Bell Labs: A Hive of Invention But we idealize America’s present culture of innovation too much. In fact‚ our trailblazing digital firms may not be the hothouse environments for creativity we might think. I find myself arriving at these doubts after spending five years looking at the innovative process at Bell Labs‚ the onetime research and development organization of the country’s formerly monopolistic telephone company‚ AT&T. Why study Bell Labs? It offers a number of lessons

Every species interacts with its surroundings‚ whether it’s within their populations‚ community‚ ecosystem‚ etc. In this lab‚ we will be comparing two different species and how they grow alone as well as together‚ in the same environment. More specifically‚ in this lab‚ we will be dealing with one of the most important ideas in ecology‚ the

Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies. The composition of a standard penny is 97.5% Zn and 2.5% Cu. In the lab we will be using Beer’s Law (A=elc+b where A is solution absorbance‚ e is a constant called molar absorbency‚ l is the length in cm‚ and c is the concentration). Using Beer’s Law in this lab a colorimeter is used to find the
