Purpose: To see how fast organisms and materials decay under certain conditions. Procedure: We gathered 4 2-liter plastic pop bottles and cut them to assemble the drawing below. Near the bottom we placed a siv to let juices drain through into the bottom 2-liter. Then we stacked materials and organisms on top of each other …
CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed …
The oxygen can be observed as bubbles comic Eng from the reaction site. Catalane is found in many living tissues of organisms, including chicken liver. T he purpose of this experiment is to determine what changes in pH, temperature, and enzyme co concentration have on the rate catalane works to break down hydrogen peroxide. If …
Biology 101 Popcorn experiment Lab partners Robert Barham Michelle hall Diva Mancada Kelley Pritt 1 Introduction Popcorn, or popping corn, is a type of corn which explodes from a kernel and puffs up when heated. It is a popular snack food, especially in movie theaters. Popcorn can be salted or sweetened. Air popped popcorn is …

The purpose of this lab is to isolate a bacterial population from the normal throat flora. A streak plate method will be used to obtain a pure culture of a Gram positive coccus genus of bacteria. Several biochemical tests will be performed to aid in the identification of this unknown bacterium. Biochemical tests are a …
Research Question: Investigate the rate of photosynthesis of an elodea plant by measuring the amount of oxygen that is produced by it. Variable: Independent Variable: The Independent variables are the different colors of cellophane paper that are wrapped around the 15 test tubes. The 5 different colors are green, blue, red, yellow and one without …
Abstract This experiment made use of the Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis technique to plot a curve displaying the electrophoretic mobilities of 7 proteins against the known molecular weights. Another sample was also run in the SDS-PAGE but with an unknown protein sample. Two proteins were found in the sample and their electrophoretic mobilities …
The agar changed from red to purple, and a noticeable border was present rounding the colonies that exhibited growth on the dish. The ASH agar did not yield a color change. The Imitation agar exhibited a change with S. erasures and the mixed culture, but no change with E. Coli (Table 2). Table 2. Indication …
The table above shows the relationship between the lung capacity average of people who do exercise constantly and the subjects who doses ‘t exercise often. As it can be observed, the blue column (represented by the average of athlete people) shows a clearly advantage above the red column (represented by the average of other subjects), …
Blah I Just want to be able to read this essay so I’m sorry if this sidesplitting to you hold on Physics Pre-AP Projectile Motion Lab Report Purpose The purpose of this lab was to determine how angle and gravity affects velocity and range. Procedure Materials Projectile launcher Marble Two measuring sticks Tin foil Pencil …
Two separate variables were hypothesized and tested within the confines of the experiment on their effects on the productivity of lactate enzyme. The measurement of light absorbency levels of different solutions based on both the concentration of o- nitrogen (NP) as well as the pH of the solution tested. To begin with, differing concentrations of …
Abstract This experiment focused on extracting and separating pigments of Chloroplast. For the procedure green leaves were grinded in a mortar with some chemicals and the fluid was filtrated to use for further analysis. Stripes of this solution were put on a filter paper and later, after dried placed into a beacon of solvent. After …
Energy (TAP), initially in the form of glucose (macroeconomics) is later formed by condensation reaction into starch (polysaccharide). These alpha-glucose units are attached together by glycoside bonds. Starch is formed after the Calvin Cycle in the Storms. Carbon dioxide is present in the air and the water is gained from precipitation or morning dew. The …
The endocrine system works with the nervous system to regulate and coordinate body functions. While the nervous system works quickly and sends messages directly to specific body parts, the endocrine system takes a longer time to produce a longer- lasting effect. The system operates by releasing chemical messengers called hormones into the bloodstream, which travel …
Affects of Osmosis and Diffusion Introduction: Perfume spreads in a room, hands bloat when left in water for too long (shrilling is a common misconception), a tea bags contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose …
Isolation of Mitochondria from Cauliflower – Weigh egg of rosettes cut from fresh cauliflower head. – Cut rosettes and place it on ice – Prepare Juice extractor by placing ice and an empty 150 ml beaker into the right compartment. – Collect pulp from left compartment and record total volume of the extract. Approve. Ml …
Specific heat is defined as the amount of energy necessary to produce a temperature change of 1 co per gram of substance. The specific heats of different substances vary, and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimeter. In this lab activity, calorimeter will be …
Also the total amount of energy in a closed system never changes. Along with my wonderful partner Kelvin e thought that energy in a closed system will remain constant throughout unless there is an outside energy such as “work” or friction. We also discussed the differences and similarities between closed and open systems. We wanted …
