Hoeung 1 Tiffany Hoeung Ms. Braceras Honors Earth Science 4 March 2015 How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1

et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light

turn off the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the water indirectly affects the gross primary productivity in aquatic plants. To measure this you would use the light and dark bottle method. Only respiration (R) can occur in the bottle stored in

Title: Esterification Objective: To synthesis acetylsalicylic acid by esterification. Introduction: A pleasant‚ often fruity‚ odor is characteristic of some of the simpler esters. Ethyl butyrate smells similar to pineapples‚ the odor of n-propyl acetate is reminiscent of pears and isopentyl acetate has a strong banana fragrance. Esters are derivatives of the carboxylic acids and contain the following functional group: The synthesis of an ester can be accomplished in one of several ways. An esterification

Synthesis of Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol

Therefore‚ it will be presumed that the result of this experiment by isolating the polyphenol oxidase within the potato extract through the oxidation of 5mM dopa solution with highly concentrated enzymatic preparation of polyphenol oxidase with a buffer as the diluent will indicate a rapid increase in the rate of the reaction as well as the amount of activity present in the potato extract. Proposing that Vmax is proportional to enzyme concentration‚ a linear relationship should be present and enzymatic
