Heart Rate Vs. Exercise & Gender Introduction The purpose of this experiment was to find out whether males or females of the same fitness levels had a higher increase in heart rate after performing the same exercise in the same amount of time. The hypothesis was that‚ with the same levels of fitness‚ females would have a higher heart rate. The main reason that this hypothesis was thought to be viable‚ was because females generally have higher heart rates than males due to their smaller heart size

Question: How does the number of sit-ups affect your heart rate. Independent Variable (IV): Number of sit-ups ( 0‚5‚10‚15‚20). I chose these 5 increments because they are consistent numbers in which everyone can participate without it being to much. Dependent Variable: heart rate( BPM) +/- 4 ( number of beats in 15 seconds multiplied by 4). Materials: timer‚ flat surface‚ movable clothing Background: In this experiment I will test your heart rate and if it increases or decreases with exercise (sit-ups)

A Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in the Journal

Reactivity of Halide Ions Purpose: There are four halide salts used in this experiment that are found in the human body. Sodium fluoride is poisonous‚ but has been traced to be beneficial to humans in the prevention of tooth decay. Sodium chloride is added to many of our foods to increase flavor. Sodium chloride is important for many life processes‚ but too much intake is linked to high blood pressure. Sodium bromide is distributed throughout body tissues. Sodium iodine controls cell growth.

Therefore‚ it is important for healthcare providers to understand the effects of hypoxia on the body to know how to treat properly and diagnose conditions. Fortunately‚ there are research findings available that indicate the effects of hypoxia on a cellular level including the effects of hypoxia on the intracellular ion balance (McCance & Huether‚ 2013). This document provides an explanation of how hypoxia can change the intracellular ion balance. Understanding the Basics Hypoxia is described as having

Moderate drinking can have beneficial effects on the heart‚ especially among those at greatest risk for heart attacks‚ such as men over the age of forty-five and women after menopause. But long-term heavy drinking increases the risk for high blood pressure‚ heart disease‚ and some kinds of stroke. According to findings published Jan. 29 in the journal Stroke. People who average more than two drinks a day have a thirty-nine percent higher risk of stroke compared to those whose daily average amounts

An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

"Join or Die." A meeting was held in Albany in the spring of 1754 to address this issue. Colonial leaders‚ officials and representatives from seven of the British colonies attended the conference. Benjamin Franklin and Massachusetts governor Thomas Hutchinson together drafted a proposal of colonial unity to combat the war against the French. It was called the Albany Plan of Union. The plan would create new layers of government including a president-general that was appointed by the crown.

I was interested in using this reaction as a means of potentially supporting and quantifying some of the theories that I have studied along with also perhaps extending on them. Aim: Using a clock reaction I shall: Investigate the effect of concentration for each reactant and use the results to find the rate equation for this particular reaction.
