Corals and Chemistry

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marine animals. Learners conduct an experiment to see whether CO2 is making the oceans more basic or acidic.
