The lab that they’re doing is talking about the ocean acidifying.you may ask yourself why the ocean is acidifying and it's because there is an ongoing decrease in the ph levels of the earth's ocean and it's caused by the uptake of carbon dioxide from the 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…
What we did for our project was create water bottle rockets. What I all learned from making water bottle rockets was really interesting. We figured out that the smaller the rocket is, the farther it will go. The reason it will go farther is because it has less weight on it, although some big rockets will go pretty far too. What I did for my rocket was get one 1-liter bottle and cut out four triangular cardboard fins. After doing that, I hot-glued the fins towards the bottom of the rocket. When I…
Radiocarbon dating was invented similarly with the discovery of the Dead Sea Scrolls. Furthermore, due to the long duration of time elapse, it was hard to date the time when the scrolls were produced. Although the hot and dry climate of the Dead Sea prevented it from rotting severely, it was still difficult to exclude the containments included in the fragments and scrolls. As a result, the process of processing the samples was intricate. At the first part of the process, the scientists tried to…
I am writing to you to explain how coal is effecting our environment and give solutions to decrease our country’s carbon dioxide emission and coal-reliance. “Coal is the dirtiest of all fossil fuels.” (Dowdey). Every person in the United States uses approximately 3.7 tons of coal each year. Coal accounts for 94 percent of our nation’s fossil energy reserves. (Fast Facts About Coal). That is a lot of coal being consumed and retrieved. Many dangers come with the recovery of coal. “Thousands of…
Ocean Acidification, a process where the pH of ocean decreases as Carbon Dioxide (CO2) concentration increases in the water from the atmosphere. Since industrial revolution, the concentration of CO2 has dramatically increased in our atmosphere due to the burnings of fossil fuels, deforestations, and many more actions that humans take to make our lives luxurious. About 30% of CO2 from the atmosphere is absorbed by the oceans, making marine life’s survival uncertain. It has huge impact in the…
Fashion is believed to have a noticeable role in the modern world. It consumes and generates big incomes for countries and it is a huge industry by itself. Many governments, companies, organizations, global brands and even princesses are making approaches towards improvement in fashion. The challenge lies in making it more sustainable, which can only be possible if it achieves an environmentally-friendly production that will have an effect on the environment, the available resources and creates…
energy in the useable form of adenosine three phosphate (ATP), and produces carbon…
the Calvin cycle. The first stage (light-dependent reactions) occurs in the thylakoid membrane, which absorbs light energy to create NADPH and a proton gradient used to power the synthesis of ATP. The latter occurs in the stroma, and results in carbon dioxide fixation. In this experiment, only the light-dependent reactions were studied. 2,6-dichlorophenol-indophenol (DCPIP) was used as an artificial electron acceptor in order to determine the rate of the light reactions by observing the…
Abstract: Hemoglobin is an iron-containing protein in red blood cells that enable the red blood cell to bind oxygen in the lung and transport the oxygen to tissues and organs throughout the body. Oxygen binds reversibly to these iron atoms and is carried throughout the blood. As part of the experiment, we computed the concentration of hemoglobin and iron in a crystalline blood sample by measuring the absorbance of the sample as methemoglobin and cynamethemoglobin at 450-650nm. Furthermore, the…
researched and found connections between the earth’s atmosphere and the rising temperature of the earth. There are still those who do not trust the science behind global warming, and debate whether global warming is a scientific fact. However, the rise of carbon dioxide emissions cannot be debated. These emissions and a number of other things are combined in to the commonly referred term of pollution. It’s a frightening thought that the pollution of the earth has been normalized to the point…
