Smeddy Harole Lab Report
The purpose of this experiment was to determine whether Smeddy the Wolverine was carrying either an illegal substance or was truly carrying a harmless, cooking ingredient, by comparing the physical and chemical properties of different cooking ingredients. During the experiment, four different substances (cooking ingredients) were tested on, plus the substance on Smeddy, with three different liquids. The five substances tested on were baking powder, baking soda, cornstarch, sugar, and Unknown A (the substance Smeddy had). The liquids used to analyze the chemical and physical changes on the substances were water (H2O), vinegar, and an iodine solution. In a spot plate, a small amount of each substance was put into three separate spots and and

    Unknown Mixture Lab Hypothesis

    For this experiment my hypothesis was correct. The purpose of this experiment was achieved by observing and finding out the characteristics of each substance. The sugar turned brown and smelled good when heated, salt turned black and smelled like burnt rubber when heated, dirt turned to mud when water was added, and baking soda started to bubble when vinegar was added. According to table 1 the data shows that the unknown substance had similar characteristics to both sugar and dirt. And so to find out if my hypothesis was correct or not experiments were carried out based on tests that were characteristics of either sugar or dirt. One experiment was heating the unknown substance to check if it would start drying up and bubbling brown. The other was adding water to test if it would turn into mud. Some mistakes that could be improved in the experiment next time is- making sure not to pour a lot of salt into the beaker when heating it, since there was a lot of salt when heating it the smell was more nastier and shocking. Also when heating the dirt not to let it burn for a long time because when washing it, it was hard to get some of the dirt…

    Observations: The color changing process took longer than we had expected. We observed that after putting the penny in the beaker, the zinc powder surround the penny, which helped it changed its color. We couldn’t complete the experiment so when we took the penny from the beaker, the change in the color wasn’t completed. There were some dark spots and some light parts.…

    In this lab, we will take a trip to the planetarium lab and will learn about Right ascension and declination, and altitude and zenith. After looking at the different points shown, we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris.…

    1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry, how efficient the subject 's body is at utilizing the oxygen inhaled, as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min, the volume of oxygen was 0.84L/min. The RQ or RER was 0.87. Based on Table 5.1(Kenney,Wilmore, &Costill, 2012; Physiology of Sport and Exercise(5th ed.) The ratio indicates that roughly 68% of the kcal that the subject was using came from carbohydrates and the remaining 32% of the kcal came from fat. During the 50W stage the volume of carbon dioxide was 2.2L/min and the volume of oxygen was 2.9L/min. The RQ was 0.79, which indicates that the 33% of the kcal that the subject was using came from carbohydrates and that 67% of the kcal came from fat. In the 100W stage the volume of carbon dioxide was 4.08L/min and the volume of oxygen consumed was 4.1L/min. The RQ came out o be 0.99, the substrate being used was only carbohydrates at this point. The 200w stage had a carbon dioxide volume of 7.91L/min and a oxygen consumed volume of 6.51L/min. The RQ was 1.2 which indicates that the body is producing more carbon dioxide than the oxygen being consumed. The substrate being used for energy again is only carbohydrates.…

    In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role, if any, that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose, lactose will separate into galactose and glucose, as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions, and will not work.…

    Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts, enzymes work by lowering the activation energy for a reaction, thus dramatically increasing the rate of the reaction. As a result, products are formed faster and reactions reach their equilibrium state more rapidly. Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions. As with all catalysts, enzymes are not consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions. However, enzymes do differ from most other catalysts in that they are highly specific for their substrates. Enzymes are known to catalyze about 4,000 biochemical reactions.…

    In the article “How Boys Become Men”, written by John Katz, he analyzes situations he experienced while growing up. Katz believes that boys become men by not showing fear or feelings and not ratting on others. As in the novel, The Other Wes Moore, both Weses are forced to become men at an early age. They experience events that push them to make decisions that make them grow and think like men do. Katz details the maturation process for boys, as the book, The Other Wes Moore, does with both Weses. They make decisions and take actions to mature and become a men.…
