Oscillators & Oscilloscope Morgan Dennis @02514008 Partners: Brittany Smith‚ Michelle Trang‚ James Anderson‚ Madison Shaw OBJECTIVE: We are going to study the features and operation of the oscilloscope. We will use the instrument to measure the frequency and amplitude for various sources. Ultimately‚ the oscilloscope will display the Lissajous figures. APPARATUS: The major apparatus used include; Oscilloscope‚ two audio oscillators‚ battery and connectors. THEORY: The oscilloscope

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease. Controlled: temperature Independent: % catalyze concentration ( Dependent: rate of reaction (mm/s) Materials: Mortar and pestle Graduated cylinder Distilled

The sights‚ sounds‚ feelings and smells that occur are just as remarkable as sitting in a park observing the life around me. Looking through my fifth floor window I can easily see two miles into the distance. The sun sets off an explosion of reds‚ blues‚ oranges and purples into the sky‚ that are visible to any naked eye. The red rooftops infiltrate

EXPERIMENT I Photoreduction of Benzophenone Introduction The study of chemical reactions‚ isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for

Tori Suchy Physical Science Honors 1st block October 4‚ 2012 Balloon Powered Car Problem: In order to create a race car that can travel a minimum of eight meters powered by a nine inch balloon. We need incorporate Newton ’s Law of Motion including speed‚ velocity‚ and acceleration. Hypothesis: If a car were to be made out of homemade materials‚ then it would be possible for it to travel 8 meters powered by a nine inch balloon. Independent Variable: building the car from homemade materials

Calculations: Conclusion: The reaction is first created by adding 4.2 mL of NaOH and 4.1 mL of Ethanol into a beaker. About 3 mL of acetone and 2.0 mL of Benzaldehyde are added into a separate beaker. After adding the two clear solutions together‚ a yellow color precipitate begins to form. Also‚ the smell of cherries emits from the solution. The solution sat for about 15 minutes before proceeding. A vacuum filtration is then used to obtain a crude product. While emptying the product onto

The kidneys are a pair of fist-sized organs located outside the peritoneal cavity on each side of the spine. The kidney is a highly specialized organ that maintains the internal environment of the body by selectively excreting or retaining various substances according to specific body needs. The process of urine formation and adjustment of blood composition involves three

Cristian Cobb 2. Tan’s mother went out of her way to prepare a disturbingly Chinese dinner because she wanted to demonstrate to her guests as well as her daughter that their Chinese heritage was nothing to be embarrassed about‚ but rather something to be proud of. She proved this by taking the menu to the extreme. For an example‚ in the last sentence‚ "For Christmas Eve that year‚ she had chosen all my favorite foods."; this demonstrates that‚ although Tan was embarrassed at the time of the dinner

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What
