Students make predictions about marine ecosystems based on combined impacts of anthropogenic and natural disturbances. They evaluate others' predictions and create concepts maps to identify cause and effect relationships.

Students watch videos and discuss ecological relationships with a focus on observing symbiosis. Then they classify the ecological relationships they observe as mutualism, commensalism, and parasitism.

Students build on their knowledge of individual impacts on the ocean to see how the whole system can react to threats and changes. They examine ways in which human actions throw marine ecosystems out of balance, explore the concept of how impacts can build, and review their understandings of ecosystem dynamics.

Students explore issues related to fisheries sustainability and simulate fish monitoring methods commonly used by scientists and resource managers.

Students identify and characterize important fishing regions on a world map. Then they use an online interactive to research the location, sustainability, and level of human consumption for a variety of seafood fisheries.

Students learn about three examples of human impacts on marine life: migration patterns and shipping, algal blooms and water chemistry, and marine debris. Some of these impacts are due to human activity in the ocean, and some impacts on the ocean are due to human activity on land.

Students are introduced to the idea that humans have enormous impacts on marine ecosystems and resources, and explore the stakeholders involved.

Students use case studies to examine human impacts on marine ecosystems. They evaluate case studies in terms of an area's history, geography, habitats, species, stakeholders, human uses and impacts, and management goals.

Students explore major marine ecosystems by locating them on maps. Students use marine examples to learn about energy transfer through food chains and food webs. They discuss how food webs can illustrate the health and resilience of an ecosystem.

Students compare and contrast two Marine Protected Areas (MPAs) by evaluating case studies. Then they learn how the MPA classification system works in the United States and apply that system to the MPA case studies.

In this lesson, students explore Marine Protected Areas on an interactive map and compare and contrast three case studies. They learn how the MPA classification system workd in the United States, apply that system to example scenarios, and create case studies of their own.

Students read a case study and debate the pros and cons of a Marine Protected Area (MPA) in the region. Then they select a MPA and develop and present a management plan for it.

Students define and provide examples of abiotic and biotic factors of different ecosystems. Then they investigate the importance of abiotic factors and physical processes within ocean ecosystems.

Students investigate the interconnectedness of the Earth's water reservoirs by learning about the hydrosphere. They then discuss ways in which humans are connected to and alter those reservoirs, especially the ocean.

Students analyze videos to make observations about species, populations, and communities of organisms and discuss their symbiotic relationships. Then they create a hypothetical marine ecosystem and describe the adaptive, trophic, and symbiotic relationships between the biotic and abiotic components of the ecosystem.

Students investigate the interconnectedness of the ocean and Earth's physical and human systems through videos, discussions, writing, and mapping. They make personal connections to their own lives and are introduced to the concept of Marine Protected Areas (MPAs).
