Corte Madera Scientific Report Abstract I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result‚ I learn that the water level and tide have positive relationship. However‚ when tide changes its direction‚ the water level is likely to stay or little change. Introduction On June 19th‚ my

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

Alhia Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For

their parents and ask‚ “Mom‚ Dad‚ can I learn to play an instrument?” Whether or not it is the guitar‚ drums‚ piano‚ or flute a child could possibly have the thought of wanting to learn how to play an instrument. When Mom and Dad end up saying no to their child they should stop and realize that when a child knows how to play a musical instrument it can help them out in many more ways than they know (iDiva). Having a young kid learn an instrument can help develop better coordination‚ build better concentration

density increases‚ concentration does as well. The density of a substance is something that stays constant‚ for solutions of material the density is expected to increase in direct translation to the concentration increasing. The theory surrounding this lab was to see in practice how density could be determined with displacement and then to determine whether the density does in fact increase directly with the concentration.

as sweat. This causes an undeniable inconsistency in our experiment. The condition of the place is also another factor as the temperature was humid and hot which can also tamper with the results and cause more sweat to be produced. If we had an instrument that could measure the exact heart rate as well as have a more stable and consistent environment then our results may differ. With these improvements and corrections we would be able to find more reliable and consistent results in further

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

Surgical Instruments Surgery has been performed since ancient times. The earliest recorded surgical operations were circumcision and trepanation. (Circumcision is the removal of the foreskin of the penis. Trepanation involves making a hole in the skull to relieve pressure and/or release spirits.) The earliest instruments used in these procedures were flint or obsidian (shiny stone) knives and saws. Stone Age skulls from around the world have been found with holes in them from trepanning.

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation
