Mouse Caffeine Experiment
The problem for this experiment is how does the amount of caffeine affect the speed and performance of a mouse. The hypothesis is if the amount of caffeine consumed by the mouse is increased, then the time at which the mouse completes a set obstacle course will decrease when time is a function of caffeine quantity. The amount of caffeine consumed by the mouse before completing the obstacle course is the independent variable. The dependent variable of the experiment is the amount of time the mouse takes to complete the course. The obstacle course, the substance from which the caffeine is obtained from, the amount of time the mouse is given to digest the caffeine, and all other environmental conditions are controls. The overall experimental control,

    The experiment did not contain any form of reaction mechanism since no chemical identity had been changed. The lab demonstrates the use of chemical molecular behavior to isolate a particular set of molecules. Caffeine had already existed in the leaf itself but needed to be separated from the other chemicals. Caffeine’s chemical structure is relatively similar to the nucleic acid purine in that they use nitrogen and is bicyclic but lacks an alkene, amine and an amide. Caffeine has a solubility of 67.0 g/100 mL in boiling water but tannins also boil in hot water to form catechin. Catechin cannot react with water but it can with calcium carbonate. The calcium carbonate was added into the reflux beforehand so the catechins can quickly change to form glucose and salts of gallic…

    In our experiment we conducted an experiment to validify our hypothesis: “ If the enzyme concentration increases, it would alter the rate of which the color changes.” We hypothesized that the increase of an enzyme concentration would result in the increase of reaction rate; our experiment provided enough data to prove our hypothesis. The function of this experiment was to investigate how the influence of turnip peroxidase enzyme on the rate of reaction. As a given we would have 20g of turnip in 500 mL of deionized water. We would have a three different trials and in those trials we would do it three times.…

    Enzymes are biological catalysts. They work by lowering the activation energy needed to initiate a chemical reaction. Enzymes work within an optimal temperature and optimal pH. Enzymes are highly specific for a single substrate. The Enzyme is usually much larger in size than the substrate it binds to. In some cases, an enzyme requires something called a cofactor to begin the chemical reaction. There were four different experiments that were executed in the enzyme lab. Experiment 7.1, the first experiment, was performed to test the effect of temperature on enzymatic activity. Based on what I know about the effect of temperature on the enzymatic activity of lactase, if the lactase used in today’s lab was extracted from human cells, I hypothesize that the optimal temperature for lactase to be in is around 37 degrees Celsius, which is the average human body temperature. The second experiment performed, experiment 7.2, tested the effect of pH on enzymatic activity. Based on what I know about the effect of pH on the enzymatic activity of lactase, if the lactase used in today’s lab was extracted from human cells, I hypothesize that the optimal pH level is 7, which is the average pH level in humans. Experiment 7.3 tests enzymatic specificity. Knowing that lactase is specific for the substrate lactose, lactase will only bind to lactose and not work with the other substrate used in this experiment, maltose. The last experiment of the lab, 7.4, was done to determine the cofactors of the enzyme, lactase. I hypothesize that EDTA, a cofactor inhibitor, will have a negative effect on the reaction and lower the amount of glucose that could possibly be produced if EDTA was not present.…

    A researcher wanted to test the effect of caffeine on sleep. Fifty students volunteered to participate in the study and signed up for one of two nights. Thirty-three students participated on Tuesday night. They each were given two cups of regular coffee to drink one hour before going to sleep. Seventeen students participated on Wednesday night. They each were given two cups of decaffeinated coffee to drink one hour before going to sleep. Each student was monitored with an EEG (a test that looks at brain function) to record exactly when they fell asleep. Students in the caffeine group took significantly longer to fall asleep. The researcher concluded that caffeine interferes with the ability to fall asleep.…

    In this experiment, the independent variables are the different types of beverages that will be used. The dependant variables (the variables influenced by the different beverages) is the running time (the time that the person will run in one lap), the amount of pushups done in one minute, how many sit-ups is completed by two minutes, and the number of jumping jacks that are done in thirty seconds. I believe that Gatorade will help your athletic performance the most, therefore the other drinks such as water, Arizona Tea, milk, Mott’s Apple Juice, and Coca-Cola is the control group. The controlled variables in the experiment (items that will stay the same) is…
