For my experiment, I choose to use both the red and green color lens filters. I initially was going to select blue, but when realizing it did little alteration apart from making white appear brighter I opted for a red and green filter. Like both my mother and father, I have Deuteranomalia which means I have a difficult time discerning from reds (appearing more brown) and greens (appearing more yellow). While my father has deuteranopia meaning his green cone is missing, I suffer from…
atmosphere. In the lab the students take a look at the shells and sit them in water that's been acidified over a week. They put the shells in the acidic water to see how the shells would respond to the high levels of acid. The guiding question to this lab was, what does different concentrations of acid do to shells? One of the best hypothesis was turned in by Cesar Olvera and it says “I hypothesis that the vinegar will slowly dissolve the shell”. Now you may ask if we had any procedures and…
Brushing and flossing your teeth is essential for keeping them white. However, there are some foods that can cause your teeth to stain. If you want to keep your teeth white, then you will have to limit your consumption of foods that stain. Foods That Stain Teeth Pasta Sauce Pasta sauce can stain your teeth because of its bright red color. It is also acidic, which cause your teeth to erode. You should consider eating broccoli or kale after you eat pasta sauce. Dark green vegetables have a film…
In this week problem, the students are presented with a table with data on altitude and temperature gathered by a weather balloon. The data is in the first column shows the data of the altitude in feet, and the second data shows the air temperature in degrees Fahrenheit. Part A asked the students to pretend that they are making a comparable metric table of the data with the same variables. The altitude need to be change into kilometer and the temperature is measured in degree Celsius, what is…
From prior knowledge, we know that when you add CO2 (carbon dioxide) to bromothymol blue the water will turn green, when you add O2 (oxygen) the water will turn blue. The experiment we investigated is how does the amount of light the plant receives affect the color of the water. We took three test tubes with water and bromothymol blue, two of them had elodea plants in them one of them the control did not. One of the test tubes with the elodea plant in a dark cabinet where no sunlight could reach…
There are many dangerous, poisonous substances around the house that can be mistaken to be safe, ingestible substances. Two of these substances that can be used everyday are distilled vinegar and ammonia. This paper will discuss the dangers of ammonia poisoning when accidentally inhaled or ingested. Both these products are clear liquids that have a strong odor. Vinegar is used in baking, salad dressings, marinades and can also be ingested daily for health benefits. A child can observe an…
indicate that there should be no more than 1 to 2 % of head-to-head linkages in polyvinyl acetate5. This differs from our results obtained for polyvinyl alcohol (0.34%) by 70 to 80%. One source of error may be from incomplete hydrolysis with the periodic acid. Literature values indicate that the degree of hydrolysis is typically 86.5 to 89%4.…
concentration of xanthine in human plasma ranges from 0.5 to 2.5 μM (40−160 μM in urine) [2]. As the metabolic precursor of uric acid, xanthine is the first indicator of an abnormal purine profile and can serve as a marker of many diseases including hyperuricemia[3], gout[4], xanthinuria[5], perinatal asphyxia[6], cerebral ischemia[7], tumor hyperthermia[8] and pre-eclampsia[9]. Uric acid is typically present at serum concentrations of ∼200−400 μM and is by far the dominant purine of this class…
Defining the Problem/Question Task 3 was to design and test a series of superabsorbent pillows to identify a quantitative trend that can efficiently clean-up spills of heavy metal ion solutions. This investigation has value to companies or people they want to find a way to efficiently clean-up spills of toxic metals in bodies of waters that could damage species in and around these waters. Experimental Design and Procedure In order to efficiently clean-up spills of heavy metal ion solutions…
The addition of the succinate was required in order for the DPIP to be reduced. The addition of the succinate did impact the reactions, however too much the succinate will not be as successful because based on Table 1.4, it was shown that the Sample ID “2” had 100μL of the succinate and it had the reaction rate of 0.68 %/min. However, with the excess amount of succinate which was 200 μL with a reaction rate of 0.0533%/min. However, no addition of succinate could definitely lessen the reaction…
