PHY 101 Lab Report Waves Lab Purpose The purpose of this laboratory experiment is to “investigate how the vibrating source affects selected characteristics of the sound produced” (Giancoli‚ 2006). Materials The following materials were used in the completion of this laboratory experiment: * Meter stick * Two paper towel rolls / cardboard tubes * Scissors * Two rubber bands * Wax paper * Transparent tape * Flashlight * Balloon Procedure Part 1:

LAB 1 Background and Hypothesis: I know I haven’t passed the lab 1 H and B but I really do not want to lose points again just for the fact I didn’t get it done in time. I already lost -5 pts and I really don’t want to lose -20 pts. So I am just gonna go on a whim here and just get it done through here so it doesn’t automatically fail me without me at least trying. Background: Test to see if people who are Left Handed would be left thumb dominant and compare to see people who are Right Handed

Animal Phyla Lab Adapted from “Phylum Lab” produced by the National Aquarium in Baltimore The diversity of animal life on Earth is astounding. Each animal has a unique body plan which allows it to survive and adapt to its given surroundings. With such an abundance of species‚ classifying animals into different categories is necessary. At first the diversity of animals can be overwhelming‚ but after further research and observation‚ many likenesses appear. These similarities become the basis for

The purpose of this experiment was to acquaint the students with basic laboratory procedures‚ methods‚ and techniques; to introduce the use of basic laboratory measuring devices; to demonstrate different methods of manipulation of numerical quantities. DENSITY AND SPECIFIC GRAVITY Materials and Methods Part 1: Density of an Unknown Solid 1. We first were asked from our laboratory instructor to attain an unknown solid and were asked to note down the number of the solid. 2. Determine

Review the introduction to Lab Topic 15 plant diversity 1 and describe the major trends in the evolution of land plants. The major trend is leaning toward the sporophyte dominating the life cycle‚ which means the gametophyte is decreasing. The reason why sporophyte might be dominating

structures. However‚ this means that once the structure of the enzyme is denatured and changed‚ the functions will most probably modify as well. In nature‚ this happens when the temperature and concentrations of different components are altered. In this lab experiment‚ we will be doing an in-depth research of exactly what happens to the enzymes‚ when it happens‚ and why it denatures the way it does. b. Hypothesis Materials and Methods a.

PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

Repeat this procedure for 10‚ 15‚ and 20 g added to the weight hanger. 6. To determine the force‚ F‚ needed to displace the spring‚ measure each of the slotted masses‚ individually‚ then convert the sum of the added masses to a weight in dynes (see lab manual for conversion). 7. The extension of the spring‚ x‚ is found by subtracting the vertical scale reading in each case from the equilibrium position reading. 8. Plot a graph with the added weight‚ F‚ on the vertical axis and the extension

PROCEDURE The four laboratories as outlined above were carried out as per the provided McMaster University 2007 Civil Engineering 3B03 Geotechnical Engineering 2‚ Lab Procedures Manual‚ under the guidance of Peter Koudys and Jamie Hamelin. 3. DIRECT SHEAR TEST (SAND) Direct shear tests are quick and inexpensive test used to determine the corresponding shear strengths and parameters of fine and coarse grained

Bubble Quality Lab Hypothesis: The sugar solution will produce the best quality bubbles because of it’s sticky texture. Procedure: First‚ three cups were labeled as #1‚ #2‚ and #3. Next‚ each cup had one teaspoon of dish detergent and ⅔ cup of water added to them and swirled around to have everything mixed. Cup #2 then had half a teaspoon of table sugar added and cup #3 had half a teaspoon of table salt added to them. After that‚ a straw was dipped into each solution separately‚ and blown through
