Ocean Acidification- Lab Report (Rubric)
Title: The effect of composition of water on the absorption of CO2.
Top Introduction: Ocean acidification refers to a reduction in the pH of the ocean over an extended period time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere.
Experimental Questions: I want to find out the different between the controls and experimental of the bubbles protocol. For doing that I to the experiment of the control and experimental, I have to put the straw and blow it in 2 min and after 2min I can see different the color is changed.
Pre-Lab Questions:
1. The gas that I blowing into the water is CO2.
2. The happens to the gas when I blow it into the water is absorbed
3. The way I measuring change in the water during this lab is they changed color (pH)
4. The measuring the pH of the water tell us that acidic is on the left side, basic is on the right side, the middle is 7 (life)
5. After studying the reactions above, the carbonic acid will affect the pH of salt water is more acid CO2+H2O=H2CO3 (Carbonic acid)
Hypothesis: bubbles Protocol: The predict would happen when I blow more air into the sea water is the color of the side that blow more air in will change.
Hypothesis: shells Protocol- The calcium carbonate in the shell reacts with the acid in the vinegar and causes the shell to dissolve. Maybe the outside of the shell is break in small pieces.
Protocol: The independent of the bubble is the color and the dependent is the score the color changed after 2 min. The constant is the exchange between the upper layers of the oceans and the atmosphere.

Data Analysis:
1. I add a lot of green color (universal indicator) into the water, then I blow it in 2 min. After two min I saw that the color was changed from 5 it changed to 6.15pH. For the hot saltwater from 7.5 changed to 6.5
2. The universal indicator tell me about the water is the pH.
3. The effects of carbonic acid in ocean water tell me that the pH is changed it color.
4. Based on the results of my experimental protocol, the factor affects the pH of the water most is hot saltwater.
Conclusion:
My initial hypothesis is correct because in biology I already learn about pH so I know that the color of the pH will changed. After the experimental I learn a lot of this, I know that pH is important, and pH needs to be adjusted to optimal levels for my fish to thrive. The oceans has an optimal pH, too. As the ocean becomes more acidic, it becomes more difficult for corals and organisms to build skeletons and shells using calcium carbonate.

Ocean Acidification- Shells Protocol
Central Question: Calcium carbonate minerals are the building blocks for the skeletons and shells of many marine organisms. The seawater is supersaturated with respect to calcium carbonate minerals. There are abundant building blocks for calcifying organisms to build their skeletons and shells.
Student Pre- lab Questions:
1. Mollusks make their shells from calcium they derive from their environment, either the food they eat or the water they dwell in. This shell is actually a part of the animal, growing as it grows, accommodating its needs.
2. I expect to happen to the shell in an acidic solution is the outside of the shell will break in pieces. And have bubble stuck in the shell.
3. Carbon dioxide is biogeochemical important in estuarine and coastal waters. It is closely linked to the organic carbon pool through photosynthesis and respiration. CO2 is also a greenhouse gas and therefore its air-sea exchange is an important issue for climate change study. The coastal ocean, with its small area but large atmospheric CO2 flux.
Hypothesis:
In hypothesis the Experimental (vinegar) will have a lot of bubble. And it has some of the bubble on top of the water.
Analysis/Discussion of Data:
1. When I immersed the shell in vinegar a reaction was happening is that the shell start creates a lot of bubbles, and bubble is stuck around the shell.
2. Animals in a lower pH ocean are exposed to that pH for longer periods of time; we are testing what a shorter period of time does to an animal. The vinegar was far more acidic than the ocean will be, so this is not a direct observation of what would happen in the ocean.
3. Shelled organisms would not be able to build their shells as quickly, and their shells would be dissolved. This could leave them open to predation, kill their food, or kill them outright by becoming too acidic to live in.
4. Shells provide a hard body for the organism, protecting it from predation. Shells can also act as a signal to a potential mate, protect an organism from the sun or desiccation, and anchor and organism to a substrate.
5. Yes. To survive, an organism needs to be able to maintain its shell, and doing so uses energy. The organism must bring in the proper materials to make its shell, convert those to a useable form, and then resecrete this material as a shell.
Conclusion:
My hypothesis is correct is correct because shell organisms and organisms that create calcium carbonate skeletons are threatened by the drop in ocean pH (rise in ocean acidity) related to increased atmospheric carbon dioxide levels.
