Virtual Urchin lab
The ocean covers 2/3 of the planet- Is it really possible that humans are changing the chemistry of the ocean?
1. Carbon in the Air: What does the graph of atmospheric Carbon Dioxide tell us?
CO2 levels
2. Ph Scale: Where do some common items fall on the pH scale? Take a screen shot of your final answers and paste below:

3: Ocean pH: How might it 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.
The carbon in the ocean water dissolves and mixes in
5: Exploring Carbon Levels and Effects: Look over the interactive and describe what happens at each of the levels:
As the year increases the CO2 increases with the year. The coral calcification is thinner.
Optimistic:
it dissolves
Middle Ground:
co2 increase, pH decrease
Pessimistic:
The CO2 increases alot more and the pH levels decreases too. The coral calcification is thinner.
6: Diversity of Life in the Sea: Sort each of the organisms into Calcifiers or Non-Calcifiers. Take a screenshot of your final answer and paste below:

7: Echinoderms Life Cycles and Skeletons: Describe the life cycle of Echinoderms and explain why they are so sensitive to changes in pH.
The 2 cell embryo, is free on its own. then, it turns into a young sea urchin larvae.
8: 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?
it destroys the whole marine food chain.
