Ocean Acidification

Students begin IS6 by investigating how dissolving carbon dioxide into water lowers the pH through the steps of ocean acidification. Students then plan and carry out an experiment to test how increasing concentration of acid decreases the mass of shells. Students also explore equilibrium, collision theory, reversible reactions and dynamic equilibrium through inquiry activities and mathematical computations. Students finish with an experiment in dynamic equilibrium through iron thiocyanate and analyze the results of their experiment with shells dissolved in acid.
