Experiment 1: Simple Harmonic Motion Dominic Stone Lab Partner: Andrew Lugliani January 9‚ 2012 Physics 132 Lab Section 13 Theory For this experiment we investigated and learned about simple harmonic motion. To do this we hung and measured different masses on a spring-mass system to calculate the force constant k. Simple harmonic motion is a special type of periodic motion. It is best described as an oscillation motion that causes an object to move back-and-forth in response to

Osmosis Design Lab November 19‚ 2011 Biology Defining the Problem and Selecting the Variables Research Question: What will happen to mass of the cell when it is placed in different solutions while trying to reach equilibrium? Background Information Osmosis is the procedure where water or different types of liquids move through a semipermeable membrane. This type of passage is considered as simple diffusion where no energy is required. This means that the liquid will have

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

Effects of Enzyme Catalysis of H2O2 by Catalase Report by: Timmy Lin (#269164729) October 17‚ 2011 Mr. Rienzi AP Biology Problem: Measuring the effects of Catalase enzymes on hydrogen peroxide decomposition. Measuring the rate of the reaction when hydrogen peroxide and Catalase are mixed at the same ratio for different time (10‚ 20 30 60 120 180 360 seconds). Background: Enzymes are biological catalysts that carry out cellular metabolic processes with the ability to enhance the rate

Blood Lab Report Introduction A blood experiment was performed testing four different patients blood to find out their specific blood types. Blood types are categorized in four blood groups based upon the antigen ( proteins on the surface of blood cells that can cause a response from the immune system) ("Rh factor" 2006) on the surface of the red blood cell. The blood groups are A‚ B‚ AB and O‚ names which are broken down from the ABO blood group system. Although simulated blood was used

transport of water molecules across a selectively permeable membrane” (Lab Manual 2nd edition). It was hypothesized that osmosis will occur when there is an uneven distribution of solute in a solvent. The more abundant the solute is in solvent‚ the higher the rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Throughout this lab‚ data was collected and compiled to analyze these effects across selectively

Rate of reaction Design Lab Background: Reaction rate is most commonly defined as the speed at which a reaction takes place. This rate can be altered by many factors such as temperature‚ pressure‚ concentration‚ volume‚ or the use of a catalyst. In order for a reaction to occur‚ the atoms must collide in the correct orientation to break the bonds and must also have more energy than the needed activation energy. If their energy is not high enough‚ the reaction will not be able to take place. By
