Ocean Acidification Formal Lab Report

Introduction- Isopods, or what your 7-year old self would refer to them as ‘Roly-Polys’, are actually a type of class crustacean. They breathe with gills, so they have to stay in damp areas with high humidity. That’s why you normally find them under rocks (Isopod, Pillbug, Sow Bug Information, 1997). Also, they like to eat Detritus and it is a more acidic plant (Animal Behavior: Pillbugs and Their Preferences, 2003-2015). This being said, would isopods refer to be in an area with low pH, high pH or water? I there is a low pH, high pH, or water, then the isopods would prefer the water because most organisms are sensitive to certain pH levels.

Many organisms use energy to perform their cellular functions. That energy comes from the energy that is stored in food then converted to adenosine triphosphate or ATP. ATP can be obtained with or without oxygen, aerobic respiration and anaerobic respiration. Aerobic respiration produces carbon dioxide (CO2) as a by-product while anaerobic respiration produces Ethanol (C2H6O) or Lactic acid (C3H6O3). In aerobic respiration the “CO2 produced during cellular respiration can combine with water to produce carbonic acid.” While CO2 is produced, the amount of CO2 produced is different depending on the organisms, in this case crayfish. To test the changes in pH, NaOH is used to neutralize the carbonic acid produced by the crayfish, by which the

Around 150 years ago, humans started releasing fossil fuels into the atmosphere during the industrial revolution. The ocean takes up a quarter of the gas that surrounds earth by absorbing the CO2 we put in our atmosphere. Scientist thought the ocean was a great resource for getting rid of these CO2 gases in the atmosphere; however, they didn’t know how much these gases where destroying our great ocean. NOVA’s documentary presents, Lethal Seas, a documentary of the destruction of our vast ocean, concentrating on the American northwest coast, Papua New Guinea among the volcanic islands of Milne Bay, and Aurora Australis. The documentary dresses the issue of rising acidity levels in the ocean and its effects.

Statement of Purpose: The purpose of this experiment is to see whether or not alkaseltzer tablets have an effect on the boiling point of 100 mL of water. The control is just water, the variable groups are 100 mL of water with one tablet, and 100 mL of water with two tablets.

This occurs because excess nutrients can fuel the growth of algae blooms that block sunlight from reaching underwater grasses and, during decomposition, rob the water of oxygen that plants and animals need to survive. Certain species of algae that are common in bodies of water plagued by eutrophication can also contaminate shellfish. When consumed by humans, these diseased aquatic invertebrate cause paralytic shellfish poisoning: a potentially fatal disease. Unfortunately, though there are many drawbacks and negative effects on the water quality in the Bay, no real benefits are found in the water when agricultural pollution is present.

“Humans are creatures of habit and of predictable emotions - that preside over logic,” writes Robert R. Barefoot in Death by Diet. He refers to the fact that we human beings, even intelligent, scientific-minded ones, tend to stick to the status quo, even when it’s not valid and makes no sense. Hence, when new information threatens his/her previously held convictions, the average scientist (being human) can use all kinds of fallacious reasoning to controvert new information - especially if his/her livelihood is at stake.

Imagine sitting in a fancy restaurant and ordering the Willapa Bay oyster special. the waiter says they don’t have any oysters.This tragedy is due to ocean acidification. Ocean acidification is happening in Washington’s backyard, but residents might not know what it is. Ocean acidification is when the pH in the ocean is replaced with more acidic substances like carbon dioxide. Ocean acidification is killing off the oyster population, which is also affecting the jobs in Washington.

The question is, how does a physical or chemical change affect the mass of a substance within a closed system? To respond to this question, my group did a lab to determine whether or not the mass would change or not. Our lab was to have a plastic bag containing baking soda, then add a cup of vinegar and a block of clay to the mix. We made sure to weight every element separately and then add them up for our total mass of 31 grams before the reaction. During the reaction, as soon as the vinegar was poured in there was a gas produced, bubbles. We immediately knew it was a chemical change, then we added in the clay. The bag was very cold and the block of clay had gone from squishy to rock solid. After they were put together and the chemical reaction reduced and calmed down. One thing we did wrong was let out a little bit of air because the bag was not fully closed, in return, it messed up our weight. Our ending mass was 30 grams. We conducted our investigation this way because we wanted to easily find a way to prove that no mass can be created or destroyed in a reaction.

Pop rocks are sugar with carbon dioxide. When they get wet like in your mouth. The candy part dissolves and gas is released. That's what makes the crackling sound. Carbon dioxide is in soda too. Carbon dioxide has a less than density of soda, so the bubbles rise. You know this because if you put a balloon on top of the top of the bottle and put pop rocks in.The carbon dioxide will fill up the balloon. Pop rocks and soda make a chemical reaction. The soda is the main part that makes the balloon fill with gases.

Acids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter. Its pH is greater than 7 and turns red litmus paper into blue.

The purpose of the experiment was to determine what happened during osmosis and diffusion across membranes by using a fresh hen’s egg.

The movie “The Day After Tomorrow” depicts a scenario in a future where humanity does not curb its pollutive ways, paving the way for a global climate shift and an apocalyptic ice age that freezes many great cities. That might be a fictitious reality, but one that is seemingly possible given the way we are destroying the environment. In recent years, there have been increasing discussion about ocean acidification, which Feely referred to as “global warming’s evil twin”. Acidification affects elementary process related to composition and role of marine ecosystem, causing long term impacts on humans (Doney, 2009). Despite the potential seriousness of ocean acidification, little attempts have been made because of the lack of motivation, awareness, capability and diverging interest.

Modern human life is polluting the world. The products that make our life livable, are a big threat to the oceans. Even places that are untouched by mankind, are experiencing the effects of pollution. Entire populations of fish species are being wiped out by overfishing, not even mentioning the species caught as bycatch. The oceans suffer a lot from pollution as well. Fishermen throwing their garbage into the ocean, which affects the health of the coral and the fish that live in it. Climate change is destroying the living environments of various animals, like the walruses. The WWF1 started their campaign Seastars to fight against the threats of the ocean.

The topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity. Ever since the industrial revolution commenced, around one third of the carbon dioxide released by human interference has been absorbed by the ocean, which is one of the reasons of the drastic change in climate as well. Without the ocean absorbing carbon dioxide, the carbon dioxide n the atmosphere would be drastically higher, with possibly increasing the levels of climate change.The point of the research is to see how will the pH affect the organisms in the marine ecosystem and does carbonation affect an organism’s mass and form. Many organisms that are part of the marine food chain are going to be affected by ocean acidification due the levels of acidity deteriorating the calcium carbonate within the animal. It turns out
