Student Learning Map for Unit: The Present and Future of the Marine Environment (6.2)
Key Learning(s):
Niche organisms play an important role in their ecosystem and can be supplanted by non-native species. Conditions challenge
organisms and dictate population diversity in habitats. Resources are distributed unevenly throughout the Earth and its oceans.
Marine policy has evolved over time in reaction to economic and environmental stimuli. Humanity and natural processes have effects
on ecosystems such as coral reefs around the world. Students have opportunities to be stewards of the oceans.
Unit Essential Question(s):
What is ecology?
How does the flow of energy through the food web affect an ecosystem?
What factors affect the productivity of an ecosystem?
Why do human activities have wide-ranging potential effects on coastal ecosystems?
How would you classify the broad range of marine resources?
Who owns marine resources?
What does biodiversity mean to you?
Are the ocean and the atmosphere linked together?
What are the different classifications of pollutants and their effects?
What is the “Tragedy of the Commons” and how has it applied to the oceans?
How do we construct marine policy for effective stewardship of the oceans?
