The importance of good exercise helps the cardiovascular system work on sudden changes on demand if an individual exhibits good exercise skills that help the pulse rate increase and decrease when the body needs it (AHA‚ 1.) The purpose for this experiment is to give the student the opportunity to measure the lung

Human ECG Abstract The purpose of these lab exercises is to understand the function and importance of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore‚ the equipment used in the experiment will show the functions in the right and left arm; as well as‚ in the right and left ankles. Finally‚ the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate. Introduction

Erin Gaudet SCI-220-01 Title: Hair Lab Object: Analyze hair samples Procedure: Same as in lab handout Results: See attached data sheet Conclusion: This type of lab analysis is important to the field of forensic science because you could link a person to a crime. The removal of hair from the body often denotes physical contact between a victim and perpetrator and hence a crime of a serious or violent nature. Forensic scientists would find this lab useful because they would be able to determine

The objective of this lab was to recreate the color profile of a given solution. In this case‚ the solution was Powerade. The final solution should match the absorbance values at the peak wavelengths (420nm and 628nm) in Powerade. This lab was done using deionized water‚ FD&C Blue #1‚ FD&C Yellow #5‚ FD&C Red #40‚ and a spectrometer. To obtain the correct color profile‚ FD&C Blue #1 and FD&C Yellow #5 were utilized in the sample solutions. The experiment was conducted over two days; the first day

Data Analysis: 1. What was the temperature change for the water in the calorimeter (ΔTwater)? 3°C 2. What was the temperature change for the metal sample (ΔTmetal)? Assume the intial temperature of the metal was the same as the temperature of the water it was boiled in. 70°C 3. What was the specific heat of water in J/g°C? 4.186 J/g°C 4. Using the following equation‚ your answers to questions 1-3‚ and your data table‚ determine the specific heat of the metal sample you tested. 5

e Crystal Eve Lopez‚ Dr. Barua Madhabi Keywords: beet root model system‚ spectrophotometer‚ betacyanin‚ cellular membrane‚ phospholipid Abstract The cellular membrane separates and protects the cell acting almost as a wall. Depending on what stressors there are the cellular membrane can become damaged. The objective of this experiment was to examine the structure of the cell membrane using the beet root model system by observing the effects of solvents on the beet root. The beet root was placed in seven solvents

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest was helium. In fact‚ helium and lab gas had a density below 0. Anyways

Celestial Geography I Emily Richarz PH090-04 Purpose: The purpose of this lab was to introduce us to star charts and how to use them to find stars‚ constellations and other bodies in the sky. Procedure: The instructor gave a brief but thorough lecture and demonstration on how to go about finding the answers on the worksheet. We then filled out the worksheet that cover finding stars and constellations using right ascension and declination in general and on specific dates‚ where constellations
