Study Activity

Perform the study activity below:

Use the Virtual Urchin at the University of Washington to study how CO2 increases in the atmosphere has promoted Our Acidifying Ocean.

  • How have CO2 levels changed in the atmosphere since 1960? Is this change significant? Why?
  • Compare the acidity of different household substances. Which are the most acidic? Which are more basic?
  • Has the ocean pH level changed during the last 20 million years? By how much?
  • How does CO2 affect substances in the ocean, such as levels of carbonic acid, bicarbonate, and calcium. How do changes in the concentrations of these compounds affect marine organisms?
  • Explore how different carbon levels will increase or decrease compounds needed for coral reef survival. Then look at other marine organisms that use or ignore calcium compounds.
