Next, students will be introduced to types of marine algae including coccolithophores and to how ocean pH changes are impacting the availability of carbonate for use in the formation of calcite shells and coccoliths. Students will then plan and carry out a small-scale laboratory to investigate the relationship between the solubility of calcium carbonate and pH. To conclude, students will read an abstract of recent research into coccolithophores and ocean acidification and compare and contrast those findings with their own investigation’s results.
