INVESTIGATION INTO THE EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a

Research Report Introduction: The scientific principle that governs this kind of experiment was Combustion Reaction. It is a reaction that another element or compound reacts with oxygen to produce energy in the form of heat and light. It is a reaction that requires oxygen. My objective in doing this experiment is to determine the effect of the height of the candle on the length of its burning time. The existing problem is Suffocation. Research Problem: What is the effect of height of the candle on

Caffeine’s Effect on Blood Pressure in Teens Research Questions How does the caffeine in coffee affect the blood pressure in teens within an hour? Purpose The purpose of the lab is to see the different effects of coffee in teenagers who have a different lifestyle. Also‚ my purpose is to be informed as well considering I’m a 17-year-old teen that drinks coffee on a regular base. I would like to know how all the coffee I have ever drunk‚ has had an effect in my body that I’m not aware of. Hypothesis

Blood Pressure? Purpose: The purpose of this experiment is to compare blood pressure as related to gender and athletic status. Hypothesis: I predict that males have a higher blood pressure than women and athletes have a higher blood pressure than non athletes Background Info: Blood pressure is the amount of force that blood pushes against the inside walls of blood vessels as it passes through. This pressure is initially

of reaction. This experiment focused on how temperature affects the rate of reaction for the reaction of alka-seltzer and water. The rate of a reaction is a value calculated to figure out how fast a chemical reaction occurs. There are three factors that can be changed that will affect the rate of a chemical reaction: surface area‚ concentration‚ and temperature. Temperature specifically affects the rate of a chemical reaction‚ because when the temperature is changed‚ the kinetic energy of the molecules

24-Hour Blood Pressure Monitoring In some patients‚ an elevated blood pressure reading taken during an office visit may not truly indicate hypertension—it could just be an occasional occurrence. These individuals are given a portable device to record their blood pressure over a 24-hour period. This helps us more accurately determine whether or not a patient usually has high blood pressure and requires treatment. Advanced Lipid Profile An advanced lipid profile test gives more information than

November 20‚ 2013 Lab Report 1. Problem: To find the density of a Hershey chocolate bar. 2. Hypothesis: I think the chocolate bar will gradually decrease in density as it gets smaller. 3: Materials: 1 whole Hershey chocolate bar‚ ruler‚ triple balance beam‚ tray‚ calculator. 4. Procedure: First‚ find the mass‚ volume‚ and density of an entire Hershey Bar. Then‚ systematically‚ break off one section at a time to calculate the mass‚ volume‚ and density for 3/4‚ 1/2‚ and 1/4

Effect of Temperature on Solubility Lab Purpose: What is the solubility of minerals in water? What is the relationship between temperature and solubility? Hypothesis: If salt and sugar are each tested in water of varying temperatures‚ then salt and sugar’s solubility will increase as the temperature also increases. Materials: Two 250 mL beakers Tap water 100 mL graduated cylinder Hot plate Two petri dishes Glass stirring rod Salt Sugar Thermometer

INTRODUCTION Osmosis is a passive movement of water molecules going across the partially permeable membrane. It is a very spontaneous process due to the downhill energy flow known as “water potential” by which‚ water molecules
