Introduction At boy band concerts‚ the general admission standing floor is an open space in front of the stage; concert attendees buy tickets at a single price and try to get as close to the stage as possible by lining up in front of the concert venue as early as two days before the doors open. During the concert‚ the general admission crowd‚ constituted by at least a hundred members at even the smallest of venues‚ is often a fertile spot for pushing‚ hair pulling‚ hitting or other types of physical

Eco-Column Lab Write up Alicia Whiteley Block 4 Abstract: In this research and experiment we were testing whether or not we can maintain a healthy eco-system based off creating one from scratch. We initially went into this experiment confident that we were going to be able to keep our fish alive which was proven wrong mid-way through due to high levels of turbidity and the state of the fish. After collecting all of our data‚ we maintained a healthy terrestrial level and a good PH

In this TLC lab‚ we explored the relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen

Separating Substances: Identifying Food Dyes with TLC Background The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer’s day or a golden Thanksgiving turkey garnished with fresh green parsley? Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow color

Band Camp This is the story of my first day of marching band. I was 15 and it was July 20. I was one of about 40 to 50 freshmen in the marching band. I had been waiting all year for the opportunity to join the marching band. I will cover 4 major areas of the day. First‚ how the day started. Second‚ when we hit the pavement to start learning. Then‚ going through the first part of the show for the first time. And finally‚ the end of the day. When I first woke up that morning I was extremely nervous

spectrum of the Spinach Chloroplast By a Different Wavelength and Photosynthesizes Activity in different light filters Instructor: Dr‚ David Danseraveu Student: Hassan Sedaghat‚ A00345910 Due date: 11/13/2012 Material and Method: In the photosynthesis system‚ plants and other photosynthesizing creatures they use light of the sun as energy by absorbing some specific wavelength. A prepared sample of the chloroplast from spinach was used during this experiment. In order

The overall experiment consisted of three smaller experiments as a result of the different properties chlorophylls possess and the need to test them individually to receive the most accurate results. Preparation for the lab began with selecting a medium to large spinach leaf and deveining it. Once the spinach was prepared‚ it was ground in 5 mL of 100% acetone‚ creating a green acetone extract. The extract was filtered through a funnel with a kimwipe and into a test tube. The volume of the filtered

Introduction Esters derive from the reaction between a carboxylic acid and an alcohol (Figure 1). Figure 1. The General Reaction Equation of Ester Formation From A Carboxylic Acid & An Alcohol. Carboxylic acids contain the functional group –COOH whereas in ester’s the hydrogen is replaced with an R denoting any alkyl or aryl group; -RCOOR’. Esters with low-molecular weights are commonly used as components in the flavor’s and odors of many fruits & fragrances’ as well as to enhance foods & beverages

DNA Extraction Lab Purpose: To compare the amount of DNA extracted from two different species‚ despite using the same method. Hypothesis: I predict that the liver will produce a higher quantity of DNA than the strawberry. This is because I believe that animals have a higher DNA yield because our structure is more complex than a plant’s structure. Materials: -Sample of Strawberries -Zip lock bag -DNA extraction buffer -Cold ethanol -Glass rod -Double ply cheese cloth -Two test tubes
