  9. 9. from the Smithsonian: http://ocean.si.edu/ ocean-acidification
  10. 10. Let’s put acid into action!
  11. 11. Break for acidification workshop (20min): Materials: 1) coral fragments – these should work well, although I handed out 5,000 yr fossil coral fragments for kids to keep 2) household vinegar in squirt bottles To do: -place coral onto table -squirt vinegar onto coral piece, let it sit for a few minutes -observe and share observations -talk about the chemistry that is happening, relate to ocean acidification
  12. 12. What’s next for the world’s coral reefs?

  14. 14. Things are happening faster than we thought. We have to reduce our greenhouse gas emissions.
  15. 15. How can kids help? 1) conserve gas, electricity 2) don’t waste food 3) eat less beef 4) plant trees
