In a series of 12 project-based learning lessons, a group of seven fifth-grade students who live 200 miles from the coast explored their personal connections to the ocean. After completing a unit on the role of water in Earth's surface processes, the students investigated ocean acidification and how this pervasive ocean problem impacts their local community. The use of project- and place-based learning allows students to experience the impact of our actions on the environment; discover a link between their communities and the ocean; and form a meaningful emotional relationship with the ocean that empowers them to take action on sustainability.
