1. Carbon in the Air: What does the graph of atmospheric Carbon Dioxide tell us?
The graph of atmospheric Carbon Dioxide tells us how much atmospheric carbon dioxide is being released into the air each year.
2. pH Scale: Where do some common items fall on the pH scale? Take a screenshot of your final answers and paste below:

3.How might ocean ph change? A change from 8.2 to 8.1 on the pH scale is a 30% increase in acidity.
4. Carbon in the Water: Explain what happens to Carbon in ocean water.
Carbon in the ocean water turns into carbonic acid.
5. Exploring Carbon Levels and Effects: Look over the interactive and describe what happens at each of the levels.
Optimistic- The H+ ions are not large in 2090.
Middle Ground- It's a bit balanced here, but the coral isn't really thick.
Pessimistic- There are lots of carbon here, with the coral becoming as thin as a stick.
6. Echinoderms Life Cycles and Skeletons: Describe the life cycle of Echinoderms and explain why they are so sensitive to changes in pH.
Echinoderms first start out as an embryo with no methods of protection. Soon after this, the embryos turn into young sea urchin larva, where it floats along with the plankton and eats microscopic algae. Soon, the larva begins to form its necessary body parts on the left side. After the metamorphosis, the larva sinks, and a juvenile crawls out. From there, it depends on its hard parts for protection when it's growing up. After a year, the juvenile finally becomes an adult. These Echinoderms are sensitive to the changes in pH because they need Calcium Carbonate in the water to build their shells. If the pH in the water changes, then the Echinoderms will have a hard time to build their shells for protection.
7. How to Study Ocean Acidification in the Lab- How may ocean acidification impact Sea Urchins in the larval stage? Can you think of any other possible acidification impacts on marine organisms other than calcification?
Ocean acidification impacts sea urchins in the larval stage by possibly hindering how the shells will develop.
