6. Go to **Discussion** in Laulima to post reflection from the presentation, 2 articles, and 2 videos.
 * Question: Carbon dioxide is one of the greenhouse gases that are accumulating in our atmosphere. What impact do you think the increase in carbon dioxide may have on the corals? Do you think other organisms would be affected? Why or why not?

7. Download the following packet, then go to Understanding Ocean Acidification to complete the Ocean Acidification simulation.

8. After completion of simulation, collaborate with a partner on the packet by completing the 3 tables and answering the 4 questions at the end of the packet. Be sure to submit a pdf of the completed answers into **Assignments** in Laulima.
