Ms. Lunsford Honors Chemistry 12/6/2011 Abstract Yeast is widely used for making bread‚ beer‚ and wine. People all over the world drink and eat those products. This projects looks at which fruit juice with a higher percentage of sugar will produce more fermentation. The original purpose of this experiment was to determine the amount of fermentation of 3 different fruit juices after adding a certain amount of yeast. By measuring the type of fruit juice (independent variable) the amount

There are more than one forms of fermentation; yeast fermentation is probably the most common method. This process is used in many everyday products today. Yeast was first discovered in 1676‚ but was used before. It has also led to numerous scientific advances. Yeast expands‚ especially well with a good amount of sugar‚ the more of the amount the greater it expands. Yeast is a single-celled organism‚ a fungus to be more specific. They consume carbohydrates‚ mainly sugars‚ and produce carbon dioxide

Cervisiae<br><br><b>Description</b> - Yeast is a unicellular organism that lacks chloroplasts. They are so small that it can ’t be seen by the naked eye and they are so small that it would take 4000 of them lined up side by side to measure an inch. <br><br><b>Habitat</b> - Yeast lives on and is nourished by dead or living plant or animal matter. The ideal conditions of yeast is high humidity and temperature‚ plus lots of food. In bad conditions though the yeast produces a second cell wall for protection and the yeast contents

A Summary of Michael Crummey’s “Bread” Michael Crummey’s “Bread” is a short love story. It’s about a woman who marries a man 20 years elder to him‚ not because she loved him; it was just a practical decision. The man in the story too has no love for her and only looks at her as a need to keep himself satisfied.

1P Paper Towel Absorbency Experiment Write-Up Purpose: The purpose of this experiment is to conduct a valid experiment‚ realize that the way I conduct an experiment influences the data‚ and I want to know which paper towel has the higher absorbency times. My hypothesis is that bounty will be the quicker picker upper Materials and Methods: As a class we chose that our control out of the brands provided (Bounty‚ Viva‚ Wal-Mart‚ and the School brand) would be the Schools brand of paper towel

Photography Write-Up: Separation The camera I use has been rented from the ERC on a regular basis‚ and is a Canon 600D or 700D. The photo’s i’ve captured for this project were shot on the standard lens‚ with a variety of settings. I also often use a mini LED light with a daylight filter in order to create more depth in the shadows in my images‚ I usually place this somewhere away from the camera in order to create angled shadows instead of images being frontlit. To start this project‚ I experimented

Transpiration Lab Write-up. Introduction Transpiration is the evaporation of water from plants. It’s not simply a hazard of plant life but it’s the engine that pulls water from the roots to cool the leaf and supply photosynthesis. The concentration of water vapor in the atmosphere is lower than that in the leaf. Because of this difference‚ water vapor diffuses from the spaces of the leaf‚ through the stomata in the epidermis. Stomata are in the lower epidermis; the lower surface receives less
