Introduction In this lab experiment our group was given four different types of synthetic blood samples‚ along with three types of synthetic anti- A‚ B‚ and Rh‚ to help identify the ABO-Rh blood types. Its purpose of this experiment is to learn about the form and functions of the bloods components‚ as well as to examine and identify different blood types‚ as many already do so and apply it to real life events‚ whether its through forensics‚ crime scene investigations or at hospitals to help identify

Lab Report The Effect of Resting on Clothespin Squeezing. Hypothesis: If you rest then the clothespin squeezing rate will increase. Materials:- Clothespin Clock Sneakers Procedure: Separate class into two groups (exercisers and resters). Exercisers will do jumping jacks for a minute. Exercisers and registers will squeeze clothespin for a minute Repeat steps two and three. Total of three trails. Precaution: Shoes must be tied. Space between exercisers. Healthy exercisers

Blood Splatter Analysis Lab Independent Variable & Dependent Variable: Independent: Blood Spatter Dependent: Diameter (size of blood splatter) Problem Statement: What height did the blood at the crime science fell from Hypothesis: Anna Garcia might have tripped which caused her blood stain to reach the maximum height of the stool‚ which means her blood splatter fell lower than her height. Materials: Gloves Eye Droppers with blood Journal Yard Stick Clear ruler Blank piece

designed to study the effect of exercise on skin temperature and heart rate. Studying the effect of exercise on skin temperature and heart rate yields understanding of how homeostasis is achieved in humans. This knowledge creates opportunity to discover more effective ways to return the human body to optimal functioning‚ rather than a reliance on natural processes. This experiment measured the change in skin temperature and heart rate of a chosen subject for four two-minute intervals of intense exercise

Lab 2: Reaction Order and Rate Laws Khadijah Maraheel Location: My apartment September 27th-28th 2017 Course Number: Chem112 Abstract: The purpose of this lab is to find the rate law of the reactants and the reactions order. My beginning thought was I would find whole numbers but that would be to easy. My answers were all with decimals. I found that my rate law Is k (HCl)1.36 (Na2S2O3)0.84. I was expecting the solution to change color but I never thought it would turn

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

Defining the problem and selecting variables In this lab‚ we will be studying the difference of heart rate between boys and girls. There are many things that can increase heart rate‚ such as exercise‚ drinking coffee‚ taking certain pills‚ drinking an energy drink‚ feeling a strong emotion‚ etc. I have chosen to use exercise as a means of increasing the heart rate of my subjects‚ more precisely‚ 20 sit-ups. There are many reasons why your heart rate increases when you exercise‚ the most important one

Research Strategies for High Blood Pressure High blood pressure or Hypertension effects more than 900 million people world wide (Hajjar‚ Kotchen‚ & Kotchen‚ 2006). This disease can affect both men and women alike and can develop at various ages. Many Americans suffer from high blood pressure and many do not know they even have this disease. High blood pressure puts an individual at risk of stroke‚ heart attack‚ and death. The purpose of this paper is to describe a research strategy toward finding

The affect of caffeine on Daphnia Heart rate Aim: To see the effect of caffeine on the heart rate of the water flea Daphnia. Introduction: Caffeine is a stimulant which is derived from leaves‚ flowers and seeds of plants. The plant uses the caffeine as a way to repel insects as it is used as a natural pesticide by paralyzing and killing certain insects. It is used as a stimulant to human the central nervous system by increasing the stimulatory of the neurotransmitters‚ however high levels
