Experiment Title: Torsion Vibration. Introduction : Torsion is the twisting of a metallic rod shaped object‚ when a torque is applied on two sides’ perpendicular to the radius of a uniform cross-sectional bar. Objective : Determining the natural frequency of a system undergoing tortional vibration. Theory : Using Newton’s second law of tortional system. ( [pic] …………………. ( Equation 1 ) where Io = mass moment of inertia of the disk Hence‚ [pic] ……..……

Research Question How will the addition of different pH buffers to amylase affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine. Usually

Life Science Lab. A. Arnold Tuesdays @ 2:30 September 30th‚ 2011 Lab Report: Nuclear and Cell Division. PART A: Stages of Mitosis in my own words. 1. Interphase: DNA has formed already‚ but it remains in the simple form of chromatin. Chromatins are structures that are loosely coiled in the cell.3 I also observed during my lab that this was the only stage where I could still see a nucleus and nucleolus intact within the cell; this is because it’s the only stage where the nuclear membrane has

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

Water lab Research Question: How many drops of water can fit on a coin? (Water properties involved are cohesion and surface tension. Cohesion plays a consequential role in the transport of water within plants specifically within the phloem. Surface tension also dictates an important role within the transpirational pull of the xylem.) Variables: Variables | Type of Variable | How it was manipulated | Independent | Water drops‚ different types of water | Determining how many drops of the

BLS CPR Training Guide CPR stands for Cardio Pulmonary Resuscitation. This involves the giving if life giving breaths and a series of external chest compression to person who has no breathing and no pulse. Often‚ CPR is associated with medical emergencies such as heart attack‚ drowning‚ chocking. It should be noted however that CPR is applicable to any situation where in the victim or patient has no breathing and no signs of life The Chain of Survival The chain of survival
