This fun lab does a great job helping students understand ocean acidification. Lab includes thorough direction, extensions, and teacher analysis answer key and hints. A big hit with my students!
I review pH with the Mystery pH Lab
first. I also cover carbon cycling. This includes: Follow the Carbon Atom Activity
and Create a Carbon Path
. Another great link to ocean acidification is the Global Climate Change Project: Oceans
This lab requires standard lab equipment and basic materials, universal indicator, distilled water, calcium carbonate (chalk can work), optional pH paper or probes.
