Ocean Acidification

Abstract

● SC.912.L.17.16: Discuss the large-scale environmental impacts resulting from human activity, including waste spills, oil spills, runoff, greenhouse gases, ozone depletion, and surface and groundwater pollution. ● SC.912.E.7 The scientific theory of the evolution of Earth states that changes in our planet are driven by the flow of energy and the cycling of matter through dynamic interactions among the atmosphere, hydrosphere, cryosphere, geosphere, and biosphere, and the resources used to sustain human civilization on Earth. Overview: This goal of this lesson is to reinforce basic scientific principles taught in the classroom and applying them to increase students comprehension of ocean acidification, an environmental issue that is threatening marine ecosystems. Students will first learn about pH and buffering capacity of solutions such as oceans. They will explore the influence of humans and marine animals and plants on the acidity of the oceans. Lastly, students will learn how natural resources and the historical rise in the use of fossil fuels has contributed to increasing atmospheric CO2 and ocean acidification.
