Earth’s Future Ocean: Acidic Or Basic
This inquiry activity allows students to use the scientific method to explore the pH of various liquids and apply the results to determine the impact of fluctuations in ocean chemistry on calcifying organisms that absorb seawater and create calcium carbonate exoskeletons. Interrelationships pertaining to the Atmosphere, Lithosphere, and Hydrosphere through biogeochemical cycles may also be explored and discussed. Background material and useful websites may be provided to assist higher level students in synthesizing current scientific research being used to project trends in Earth’s future climate and changes to ocean’s chemistry.
