process of both cabbage and cucumber using a variety of selective media. If fermentation is performed‚ then the CFU/ml of the bacteria should decrease along with the pH. Introduction: The fermentation of foods has been a long standing tradition and practice among many civilizations‚ as it was once a means to keep foods fresh and or edible over long periods of time. Today the process of fermentation has become a living/industry for some‚ and a hobby for others. For the purposes of this lab it was asserted

original state and the percent of the hydrate recovered was calculated by using the mass of the rehydrated sample by the mass of the original hydrate and then multiplied by 100%. Data Presentation & Analysis Table 1: The data was collected from the lab experiment. Sample calculations are shown. Mass of beaker with sample 30.765g Mass of empty beaker 30.263g Mass of sample .502g Mass of beaker with sample after 1st heat 30.661g Mass of beaker with sample after 2nd heat 30.657g Heating mass

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

Stream Ecology Lab Report Jesse Paner Bio 192 Professor LaMontagne Introduction Ecology is the scientific study‚ which focuses on the interactions between organisms and their environments as well as interactions with other organisms. Stream ecology is a subset of ecology that observes the interactions between the organisms found within the stream and their interactions with the stream itself. A contributing factor to stream ecology is leaf degradation. Leaves that fall into a stream create a significant

Misael Acosta Photosynthesis Lab Report Ms. Rocha AP Biology 4th Period II. Intro/Background 1. In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CO2‚ and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of O2 or the consumption of CO2. All the oxygen within the leaf disks will be removed before being placed

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

The fur is short and greyish brown to yellowish brown on the back and paler on the underside. Adult males have a dark orange-red collar and females a more yellow-orange collar. Juveniles lack this collar and tend to be uniformly grey.1 Eonycteris robusta (Philippine dawn bat) Dawn bats occur in a variety of habitats‚ including forests and cultivated areas. These bats are

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

I was able to detect the coliforms from the fermentation in lactose broths‚ then with the IMViC test I was able to identify the enteric bacteria colonizing in the water samples. By then end of the experiment‚ it was apparent that the USM Creek and Leaf River were the two that tested positive for possible
