Iker Lopez Anatomy & Physiology P2 Wednesday‚ September 19‚ 2012 Heart Rate Response to Baroreceptor Feedback Lab Fundamental Question: Does the body respond to its environment? Testable Question: When the body is in the squat position to normal while the time limit stays the same and how far you squat is the same‚ will the heart rate recover after returning to standing position in 10 seconds? Hypothesis: If the body moves back to normal position from squatting position while the time limit

6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering‚ Environmental Engineering‚ and Petroleum Engineering. “Electrical Filters‚” (Electrical)‚ written by Joe Schmoe‚ is a lab report made by a student at a university. The College Board produced an environmental lab report named‚ “Monitoring Air Quality

Introduction: The purpose of this lab will be to investigate the concepts of accuracy and precision for quantitative measurements using density as an example. The density of a sample will be found experimentally and compared to a known value. The relationship of averages and different analysis techniques to percent error will also be explored. Density is a characteristic of a substance which can qualitatively be described as the amount of matter (mass) squeezed into a given space (volume). The

Kharishma Patel BIO 3422-E Urine Analysis Lab Objective The objective of this experiment shall be to examine the effects of different types of fluids on the renal system including rate of urine production‚ pH‚ and specific gravity. Hypothesis The group drinking water will have the highest rate of urine production. The group that drinks water only when thirsty will have the lowest rate of urine production. The specific gravity of urine for all treatment groups will be around 1.000. The pH for

In this Lab the students were required to do several tests and measurements and then convert these units into other units. There were five tests in all. The first test was measuring the average of three broad jumps in centimeters then find out how many jumps it would take to travel one mile. The second test involved measuring a candy bar (for my group we used a snickers bar) then finding out how many snickers bars end to end it would take to wrap around the equator of the earth. For the third measurement

Qualitative Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds‚ one solid and one liquid‚ from an ethereal solution using the techniques of chemically active extraction‚ vacuum filtration‚ simple distillation‚ and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges‚ and analyzing IR and proton/carbon NMR spectrums It was determined

Introduction In this lab‚ the density of 20 glass beads were determined using two different methods and the results were compared to see how close the values were to each other. In first method the volume of each individual bead was measured using the diameter of each bead‚ along with the mass. In the second method the beads we treated as a whole unit. The total mass was measured and volume was measured based on the amount of water that was displaced in a graduated cylinder. Then‚ the beads

In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of

An astronomer has a goal to discover and understand the nature of objects in our universe. Astronomers analyze and interpret the information obtained in order to make accurate models of these objects using instruments that collect‚ record‚ disperse and magnify the light that celestial objects give off. In this laboratory I learned how to measure the altitudes of stars using a quadrant. A quadrant is a quarter of a circle that has been divided into 90 degrees. I also learned how to find the angular
