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…

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…

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…

Background Stoichiometry is a branch of chemistry that measures the quantity of chemicals in a reaction. This branch relies heavily on moles and balancing. A mole is a unit of measure for giant quantities. It is a number of atoms or molecules that is so large that it is only logical and convenient to use it for atoms and molecules. One mole is 6.02 x 1023 atoms or molecules. We call this Avogadro's Number. Furthermore, balancing chemical equations is the process of changing determining the…

1. There is not much known about phage influence on microbial communities in extreme thermal environments. What may be one of the roles these phages have in this environment? - Phages are an important components of surface hot springs, they are abundant and active components of hot springs capable of killing a significant proportion of the resident microbial populations. They play an important role as predators of hot spring microbial communities and influence carbon and nutrient cycling in…

slowly. In order to speed up the process, hydrochloric acid (H+) was used as a catalyst. A catalyst is a substance that can speed up a reaction by lowering the activation energy of the reaction. It does this by changing the mechanism of the reaction and providing more energetically favorable elementary steps that would otherwise not exist without its presence. In addition, a catalyst does not get used up in the reaction. In this case, hydrochloric acid reappears in the products of the reaction…
