Standard Components of a Lab Report INTRODUCTION Writing is a powerful tool. Effective communication is necessary to succeed in any field. As a professional‚ you must communicate with both your colleagues‚ and the community at large. Writing is the means of showing the value of your work. The specific style of writing in science is based on the unique audience of readers. In addition‚ writing allows one to organize one’s thoughts and clarify ideas‚ and it fosters abstract thought‚ an ability essential

Investigating a factor that affects the rate of enzyme activity Enzymes speed up reactions. They have an area with a very particular shape called the ‘active site’. When the right molecule comes along (substrate molecule) it will fit perfectly into the active site and there will be a reaction. After the reaction the products then leave the active site. This process is often referred to as the lock and key theory as only one enzyme can carry out one type of reaction. The catalase enzyme speeds

The aim of our investigation is to find out whether the use of different sugar isomers with yeast‚ will affect the rate at which the yeast respires at. The sugars to be tested are fructose‚ galactose‚ glucose‚ lactose and sucrose. Their effects on the respiration rate of yeast to be observed through the measurement (cm3) of the displaced water‚ which will tell us how much CO2 has been respired over 2 minutes. To compare the effects an average will be calculated for each and a result will be drawn

religious ideas or cultural ideas that their cultures had. Since pre-historic era‚ abstract and stylized art pieces were used to reinforce the cultural norms‚ for people did not have any other medium of communication to convey the cultural norms except through visual objects. Thus‚ the idea of conveying messages and norms through visual objects began as cultures developed. The method of conveying ideas through abstract art hence continued since then.

Hydrogen Peroxide in the Presence of Yeast Abstract A number of different variables‚ such as the concentration of the hydrogen peroxide solution or the temperature at which the reaction occurs‚ can affect the rate at which yeast breaks down hydrogen peroxide. To prove this we first tested the solution with 3% concentration of peroxide‚ the paper that was soaked in yeast rose in 1.7 seconds. After that we changed our concentration to 2.25%‚ 1.5%‚ and .75% of hydrogen peroxide to see the effects

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Paul Jackson Pollock‚ known professionally as Jackson Pollock‚ was an American painter and a major figure in the abstract expressionist movement. He was well known for his unique style of drip painting. He was born on January 28‚ 1912 in Cody‚ WY. He had a nac Modern and Abstract art. In 1942 Pollock met Lee Krasner while they were both exhibiting in the show at Mcmillen Gallery. Three years later‚ in 1945‚ they were married. Pollock observed American Indian sand painting demonstrations in the 1940’s
