Ocean Impacts

Engage

30 Minutes

Present the students with an article, video, podcast, or images that depict issues related to human use of the ocean.

Some examples include:

• Read about the Fur Seal Disentanglement Project in the Pribilof Islands. 
• Video of northern fur seals entangled in fishing gear. (Minutes 5:48-7:40 are fur seals)
• Video of marine debris clean up in Alaska
• ADFG information and images of entanglement

Discuss as a class or have students use their science notebooks to:

• Ways entanglements can effect wildlife.
• Describe other ways that you think trash of any kind might affect marine life.
• What do you think would happen if no action was taken to help the seals in the Pribilofs.

Other Videos to consider:

“Altered Oceans “ is a 5 part series. Part four is about plastics in the ocean and is very interesting.

Algalita Marine Research Foundation

Brainstorm ways that human interactions with the ocean might cause harm to other species that use the ocean, or that might prevent future generations of humans from using the ocean’s resources.

Explore

180 minutes

Present the students with a list of possible issues related to human use of the ocean. Alter the following list of suggestions to fit your situation and your class’ interests:

• Bycatch (unintended catch of “other” fish and marine mammals by fishing trawlers).
• Pollution from cruise ships.
• Erosion of beaches and riverbanks from recreational activities (4-wheelers)
• Oil spills.
• Fish farming (invasive species, waste production that pollutes water).
• Marine debris.
• Overharvesting and competition for subsistence food.

Divide students into groups of three or four to research an ocean issue. You may want to decide on a few issues and have students choose groups according to their interests, or assign students to groups first and then have each group choose an issue.

Each group will use Internet, library, and community resources to investigate their chosen issue. You can use the resources section of this website to help provide resources to the students. Explain to students that they will be making a colorful poster that includes graphics and text, to inform and educate others about their issue. The poster will be supported by a two to three page narrative that answers the four research questions in the research guide in depth and detail.

Distribute the research guide and discuss it with students. You might choose an issue to use as an example of what their research might look like, as you talk through the research guide. Explain that they will use their science notebooks to record their findings and the sources that they used.

Help the groups to organize ways to share the research tasks, and show them available resources. Allow time to explore the resources.

At the beginning of the next class period, work with students to develop a rubric or a checklist that sets clear criteria for the poster and supporting paper that they will produce as a result of their research (see example). Set a timeline for completing the research. Show students the following sample posters at these sites (or print ahead of time):

• Long Island Sound Study posters
• Informational posters from USGS

Explain

120 minutes

Have the student groups share their research with each other through a poster session.

Allow time for each group to create a poster that displays the important findings of their research.

Student groups will rotate through the poster “stations” to look at the posters and generate questions about the issues.

At the beginning of the session, have students use their Science Notebooks to reflect on what they already know about each of the issues to be presented and what they would like to know.

As they view the posters they should come up and record on note cards, post its, or slips of paper.:

• Questions 
• Links to other human impact issue
• Additional solutions or ideas to address the problem
• Additional information including facts, key vocabulary in another language, or personal stories related to the topic

Elaborate

30 minutes

Distribute the questions to each group, about the poster that they made. Allow time for them to follow up on questions or suggestions that arose from the poster session, and to refine their displays for sharing at the final Friends of the Sea celebration.

Extend

Students can engage in hands-on activities to better understand the science involved with some of the ocean issues that they researched.

Some examples are in the Project Wild curriculum or the Prince William Sound Alaska Oil Spill Lesson Bank.

Research jobs or careers that are important to the issues. Students could choose one person, job, or career that they have come across in their research. It might be a marine biologist, an environmental officer, a subsistence user, a boat captain, or any other important user or problem-solver. Ask them to find out about the day-to-day activities and duties of the job and what kind of training is needed.
OR
Ask students to write in their science notebooks, “How could I become involved as a scientist in working to solve this problem?”

Evaluate

Use the rubric that was developed to assess students’ research results. (see example)
Students’ questions and answers during the poster session may also be used to evaluate their depth of understanding.

Curricular Connections

Language Arts. Students will be developing and practicing oral communication skills.
Writing. Students will be using their research skills, including citing of sources. To further address writing standards, students could write “formal” research papers to accompany their posters and presentations.

Social Studies. Connections can be made to history, economics, and cultural considerations for most of the issues that students will research.

Math. Students can graph and/or analyze data associated with their issue.

Ideas for adapting to different local environment or context:

• If possible, choose issues to research that are important and relevant to your community and your location.
• Interview and include local people who have knowledge of the chosen issues or jobs that are related to the issues.
• In interior areas that are far from the ocean, emphasize watershed and ecological connections and the idea that what happens upriver ultimately has an impact on the ocean.
