Investigative Quest The purpose of this experiment was to find out how music affects the female human heart rate. Hypothesis My hypothesis is that female resting heart rate will increase as the music tempo increases. If the tempo is slower the heart rate will stay at resting heart rate or decrease. Variables The variables used in this experiment were: • The tempo of the music. • The subject’s heart rate. • The subject’s age. Controls The controls used in this experiment were: • How long the subject

the difference in heart rates before and during intense exercise. Aim: The aim of the investigation was to discover how the heart rate varied with the intensity of exercise. The heart rate is a term describing the regularity of the cardiac cycle. The heart rate is the amount of times it contracts (beats) in a unit of time‚ nearly always per minute. At rest the adult female’s heart rate regulates 75 bpm (beats per minute) but this varies between people. If the heart rate is measured before‚ during

environments affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency to catalyze the reaction. We measured the rate of reaction‚ by using

Internal Assessment: Rate of Evaporation Ann George Mr. Frias/4th Period Wheeler High School Research Question How will changing the molar mass of alcohol affect the rate of evaporation‚ represented by the change in temperature over time‚ measured using a temperature probe? Research/Abstract Alcohol is an organic compound in which the hydroxyl functional group‚ OH‚ is bound to a carbon atom. Its carbon center should be saturated; it should have single bonds to three other atoms. The different types

Factors that affect exchange rates. Like any price‚ the exchange rate deviates from the cost basis - the purchasing power of currencies – under the influence of supply and demand of currency. The ratio of the supply and demand depends on several factors. It reflects connections with other economic categories - cost‚ price‚ money‚ interest‚ balance of payments‚ etc. There is a complex of interweaving and nomination of decisive factors. Among them are the following. • 1.The rate of inflation. The ratio
