Essential Question: The ocean covers 2/3 of the planet- Is it really possible that humans are changing the chemistry of the ocean?
Yes, is it possible that human by the use of the sciences and technology might or can change the chemistry of the ocean.However because it is so big , it may took a little bit of time to finally change all the chemistry of the ocean.
1: Carbon in the Air: What does the graph of atmospheric Carbon Dioxide tell us? The graphs displays the CO2 levels measured at the Mauna Loa observatory in Hawaii 1958-2008.
2: pH Scale: Where do some common items fall on the pH scale? Take a screen shot of your final answers and paste below:
Picture is shown to the right side>>>>>
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.
When the carbon combines with water molecules it becomes carbonic acid , which means that ocean acidity increase.
5: Exploring Carbon Levels and Effects: Look over the interactive and describe what happens
at each of the levels:
Scenario 1: Optimistic
Every 10 years the pH of the ocean water decreases .2%, on the other hand CO2 increases.
Scenario 2: Middle Ground
Every 10 years the pH of the ocean water .2%, on the other hand CO2 increase by 1.6
Scenario 3: Pessimistic
Every 10 years the pH of the ocean decreases 2% , and the CO2 increases.
6: Diversity of Life in the Sea: Sort each of the organisms into Calcifiers or Non-Calcifiers.Take a screenshot.

7: Echinoderms Life Cycles and Skeletons:
Describe the life cycle of Echinoderms and explain why they are so sensitive to changes in pH.
at first they start as larva then they grow becoming of hat its called urchin lava. After this larva starts groing it start developing some juvenile structures, and right after the skeleton developed to its mature style it becomes of what we call methamorphosis.
8: How to Study Ocean Acidification in the Lab-
How may ocean acidification impact Sea Urchins in the larval stage?
It make the ocean more acidic , which makes more difficult to these larva to develop their skeleton.
Can you think of any other possible acidification impacts on marine organisms other than calcification?
Another factor that may affect the ocean acidification can be the dirty waters that industries throw into the ocean.

Welcome to the Ocean Acidification Lab!
- Complete the pre-lab certification.
- Look at the first slide under the microscope- Describe what you see.
- I see a larve in circle form , it also turns to normal light, ere you can barely see it it.
- Fill two flasks with sea water and label them with “pH 7.7” and “pH 8.1”. Explain why we are using these two pH values for this experiment.
- We are using to different kinds of pH's so then e can see the differences of these two different factors. Also because the pH of ocean water is 8.1 while the 7.7 ph can be the the average ph for an end of a century.
- What happens to the pH of the first sample when Carbon Dioxide is added? Explain.
- the ph increases.
