Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable Chart: DEPENDENT

Topic: Human Cardiovascular Physiology- Blood Pressure and Pulse Rate Determination. Hypothesis: Exercise can raise the blood pressure and the pulse rate. Aim: To determine the effect of exercise on the blood pressure and the pulse rates of students in the class. Introduction: The blood pressure of a person is the force exerted by the blood on the walls of the arteries per unit area. The blood pressure unit is mmHg. The blood pressure of an individual is expressed in two ways‚ the systolic (due

9/20/2013 Methicillin-Resistant Staphylococcus aureus Methicillin-Resistant Staphylococcus aureus also known as MRSA is a bacteria frequently found on the skin of generally healthy people. MRSA is usually spread through skin to skin contact or contact with an object containing the bacteria. Most of the time you may be carrying the bacteria but you are not ill. Mostly people with weak immune systems and have been in health care centers

Methicillin Resistant Staphylococcus Aureus Staphylococcus aureus is an important and common pathogen in humans. It is found in the nose or on the skin of many healthy‚ asymptomatic persons (i.e.‚ carriers) and can cause infections with clinical manifestations ranging from pustules to sepsis and death. Most transmission occurs through the contaminated hands of a person infected with or carrying S. aureus. MRSA infections frequently are encountered in health-care settings (Lowy‚ 1998). A common

The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye

and developmental processes‚ thus it is critical for plants to optimize the ethylene production at developmental transitions as well as during stress response. Ethylene is derived from the amino acid methionine‚ which in the first step is converted to S-adenosyl-methionine (AdoMet) by AdoMet synthetase3‚4. The 1-Aminocyclopropane-1-Carboxylic acid Synthase (ACS) catalyzes the conversion of AdoMet to 1-aminocyclopropane-1-carboxylic acid (ACC)5‚ which is the rate-limiting step in ethylene biosynthesis

exerted by a fluid at equilibrium due to the gravitational pull. The fluid is known as hydrostatic fluid. The pressure can be calculated from the control volume analysis of a small cube of fluid. It is known that pressure is force applied per unit area P = F/A‚ and the onlyforce acting on any such small cube of fluid is the weight of column above it‚ we can calculate the hydrostatic pressure by: The sumary of the theory is the force on any flat surface is the average pressure acting on the submerged

bending or flexural deflections. The amount of flexural deflection in a beam is related to the beams area moment of inertia (I)‚ the single applied concentrated load (P)‚ length of the beam (L)‚ the modulus of elasticity (E)‚ and the position of the applied load on the beam. The amount of deflection due to a single concentrated load P‚ is given by: Objective: Is to find the relationship between the deflection at the center of a simply supported beam and the span‚ width.

The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation
