In this activity, teams finalize their Call to Action for inclusion in their magazine to convince their target audience to become a part of the global solution to the plastics crisis. Teams also begin working on their front and back covers, which will hook their readers’ interest with carefully chosen imagery about the plastics crisis.
DIRECTIONS
Plastics: From Pollution to Solutions unit driving question: How can humans solve our plastic problem in the ocean?
Knowledge + Action = Power lesson driving question: How can your publishing team maximize positive impact on your community and the environment?
- On the board, write the words “Knowledge = Power.” Ask students if they have heard this saying before, and whether or not they agree with it.
- After time for discussion of various viewpoints, write a different sentence: “Knowledge + Action = Power.” Ask students how these words compare to the other words, and whether or not they agree with them.
- Tell students they have gained a lot of knowledge about plastics, and now it is time to turn that knowledge into power through action by completing the final elements of their magazines, namely, their final Call to Action and the front and back covers.
- Prompt teams to take out previously distributed materials:
- Call to Action Graphic Organizer, which was completed in the previous activity, Choosing an Audience
- Final Project Checklist and Rubric
- Ask teams to identify the relevant sections of the rubric that will guide their work today.
- Distribute the Call to Action for Readers handout and introduce the task to teams. This handout will help teams draft the text for their Call to Action.
- Guide teams to fill out the first page of the Call to Action for Readers, including Who? (the target audience), What? (the desired future action), and these additional sections:
- How? Teams provide some details about how the change can take place. This could include addressing obstacles to acceptance and implementation of their solution.
- When? Teams should create a timeline for the action that is ambitious, but reasonable. Remind students to balance the urgency of the crisis with the knowledge that real change does not happen overnight.
- Why? Teams explain the negative impacts of plastics as well as the benefits of their proposed solution. They should make a convincing argument supported by data and evidence they have learned during this unit.
- For the second page of the Call to Action for Readers handout, instruct teams to sketch engaging images to represent before and after their desired action takes place. Remind them to sketch their drafts lightly in pencil, because they may decide to modify their images after receiving peer feedback in the following activity.
- The purpose of these images is to help the target audience visualize the differences made by following the Call to Action.
- The “before” image: This should include the current behaviors of the target audience with respect to the target plastic. For example, this image could show people drinking out of single-use plastic water bottles and littering them or putting them in the trash instead of recycling them.
- The “after” image: This should include the desired future behavior of the target audience with respect to the target plastic. For example, this image could show people drinking out of reusable bottles and refilling them from safe drinking water sources.
- Display the website Five Irresistible National Geographic Cover Photos and National Geographic Comes Up With An Iconic Cover To Raise Awareness About Plastic Pollution, about a cover that focuses on the problem of ocean plastics.
- Remind teams that their goal is to create a cover that is both compelling and informative. Clarify that the cover must be original visual artwork: It can be a drawing, painting, photograph, or collage, but it must be created by the publishing team and not copied from an external source.
- Ask: What does it mean for a cover to be compelling?
- Possible answers:
- It makes the reader want to open the cover and learn more.
- It makes the reader feel a strong emotional reaction.
- Scroll to each of the five images on the website and discuss with students.
- Ask: What makes this cover compelling? What makes this cover informative?
- Possible responses:
- Inside Animal Minds is compelling because the dog is looking straight at the reader. It is informative because the dog looks inquisitive and relatable, which connects to the main idea of the story about animals with “a world-class vocabulary.”
- Yellowstone Supervolcano is compelling because it is a colorful and unfamiliar image with a teaser line about “what lies beneath the park.” It is informative because you can see people if you look closely, which tells readers about the scale of the image.
- The cover with the Afghan refugee is compelling because the girl’s story is mysterious, and the reader may want to know why she is a refugee and what she fears. It is informative because it tells the reader where she comes from and that she is fleeing some type of conflict.
- Explain that in addition to the front cover, teams will also create a back cover of their magazine.
- The back cover does not need to be illustrated, but should contain basic information for their target audience about who created this magazine and why.
- Basic information may include their school, grade level, and some type of contact information. The purpose of contact information is so that their target audience can reach out with questions or comments.
- You may prefer to list contact information for the school, or for a shared class email account, if students are not comfortable sharing personal contact information.
- Provide time for teams to draft their front and back covers.
- Teams will have time to finalize these drafts in the next activity, but they should have at least a working draft of both by the end of this activity.
- At the end of class, share draft cover designs with a gallery walk.
Informal Assessment
The Call to Action for Readers and magazine cover provide evidence of students’ ability to tailor their message to a target audience and to apply their scientific knowledge to solve a complex global problem.
Extending the Learning
Consider coordinating efforts with a social studies, visual art, and/or language arts teacher to prepare students to share their magazines with the broader community.

Publishing teams finalize their magazines, including the Letter from the Editors, and prepare for publication. They also provide constructive feedback to another team using the Final Project Checklist and Rubric.
DIRECTIONS
Plastics: From Pollution to Solutions unit driving question: How can humans solve our plastic problem in the ocean?
Knowledge + Action = Power lesson driving question: How can your publishing team maximize positive impact on your community and the environment?
- Announce that publishing teams are in the home stretch. They have learned all the information they will learn in this unit, and now it is up to them to deliver their important message to their target audiences. But first, they must finalize and proofread their magazines to ensure that their products are complete, accurate, and well-organized.
- Have students take out their Final Project Checklist and Rubric and instruct them to check off each element that is complete. Remind students that some elements of their project are still in progress, such as the glossary.
- Introduce the Letter from the Editors handout and task:
- Explain that the Letter from the Editors will go inside the front cover of the magazine.
- The purpose of this letter is to introduce the target audience to the problems and solutions of ocean plastics and explain why the Call to Action is essential.
- This letter will make a claim that human production, use, and disposal of plastics can have both positive and negative ecosystem impacts. This claim must be supported by evidence and reasoning using the C-E-R format.
- Encourage publishing teams to discuss how they will divide the remaining tasks.
- Once teams have a plan for dividing up the remaining elements of their magazines, provide time in class for them to work.
- Remind publishing teams that every magazine needs to be proofread and edited before it can be published to ensure the target audience can read and understand the issues and information clearly.
- During the peer review process, publishing teams will review another team’s work. Determine in advance how you will structure the process.
- Review expectations for peer editing and feedback:
- Every peer reviewer must use a Final Project Checklist and Rubric. They should make notes on the rubric as they go through the project.
- Peer reviewers will not write directly on the draft magazine documents. Instead, they should use sticky notes to indicate suggested changes or questions.
- Peer reviewers should strive to make positive comments as well as constructive comments. Feedback is most useful when it is specific.
- As in other magazine workshop activities, peer editing teams should divide duties to edit their work.
- Since there are 10 elements of the magazine and four students per team, each editor can be responsible for reviewing two to three elements. Alternatively, pairs of editors could each be responsible for reviewing five elements.
- While teams are engaged in peer editing, circulate around the room and provide feedback to teams. Ensure that each group has completed all 10 elements on their Final Project Checklist and Rubric and that they are using the rubric as they finalize their work and edit the work of others.
- Four elements of the magazine are especially writing-intensive (Letter from the Editors, Call to Action for Readers, Featured Marine Organism Profile, and profile of the winner of the Ocean Plastics Pollution Solutions Contest). Keep this in mind as you circulate, especially when working with teams and students who struggle with written assignments.
- Peer editing can still take place even for teams that have not yet finished all 10 elements of their magazine.
- Provide time for publishing teams to incorporate feedback from their peer editors.
- When final revisions are complete, have publishing teams organize all 10 elements of their magazines into their project folders and turn them in.
- When grading magazines, make comments on the Final Project Checklist and Rubric and/or using sticky notes so that the magazine can still be delivered to the target audience.
- If the peer editing teams did not provide comprehensive feedback, or if the publishing team did not incorporate all feedback, you may consider returning magazines to their publishing teams for another round of edits before sharing them with the target audience.
- Consider making electronic copies of each team’s magazine so that you can also share your class’ work with us and other National Geographic teachers around the world @NatGeoEducation.
- If your class is producing hard-copy paper magazines, try to find a way to bind each team’s magazine without using plastics (see Tips for suggestions).
- Instruct publishing teams to carefully arrange their pages exactly as they want them before binding.
- Make sure that each team has included only the pages that will be in the final magazine, since their project folder also contains other drafts, graphic organizers, and handouts that will not be appropriate for inclusion in the published product. Teams should consult their Final Project Checklist and Rubric for the complete list of magazine pages.
- If your class is producing digital magazines, students can produce work online, or each page can be scanned for compilation into a single document with an appropriate title.
- Ensure that your classroom has sufficient devices available to display each group’s digital magazine during the final activity.
- Once your magazines are digitized, consider sharing them with the broader National Geographic educator community online!
Rubric
Evaluate students’ published magazines with the Final Project Checklist and Rubric to assess their fulfillment of the standards addressed in this unit. Be sure not to write on the magazines themselves so that they remain in their original condition for the final activity.

Students share their magazines and imagine how different target audiences may react to their Call to Action. Finally, they reflect on their experiences in this unit, looking inward to see how they have changed and outward at how they want to change the world.
DIRECTIONS
Plastics: From Pollution to Solutions unit driving question: How can humans solve our plastic problem in the ocean?
Knowledge + Action = Power lesson driving question: How can your publishing team maximize positive impact on your community and the environment?
1. Facilitate the publication presentations to an invited audience.
- Display each team’s final magazine around the room for a gallery walk.
- The time necessary for this step will vary greatly depending on your students’ success in inviting their target audiences to your class.
- Welcome any guests to your classroom.
- Provide name tags so guests can write their names and titles. Students may also want to wear name tags.
- Ask for a student volunteer to explain the purpose of this unit of study.
- Possible response:
- We studied the crisis of plastic pollution in the oceans and the problems that it causes.
- We also researched solutions and proposed our solution to members of the community.
- Ask another student volunteer to introduce the various elements that are included in each magazine.
- Possible response:
- Each magazine has a front and back cover, a Food Web Infographic showing biomagnification in a marine ecosystem, an Ocean Plastics Movement Model, a Featured Marine Organism Profile, a profile of the winner of the Ocean Plastics Pollution Solutions Contest, a glossary of vocabulary words, a Letter from the Editors, and a Call to Action.
- Explain to guests that each publishing team chose a different target audience and developed a different Call to Action. Ask each team to briefly name their target audience and describe their Call to Action.
- At this point, make sure all outside guests know which publishing team invited them.
- Provide time for guests to receive a presentation of the magazine from the publishing team or read the magazine in paper or digital format.
- Provide time for guests to ask questions of students and to give their initial reactions to the Call to Action. The guests may answer questions, such as:
- What did you learn from reading the magazine?
- What did you find interesting or thought-provoking?
- What questions do you have for the publishing teams about their projects?
- How realistic is it that you will be able to accomplish this Call to Action and why?
- What barriers or obstacles would prevent you from being able to accomplish it?
- What suggestions or advice do you have for the publishing team?
- Thank your guests for attending and make sure students have exchanged contact information to stay in touch with them in the future.
2. Show the picture of reflections and ripples.
- After guests have left, ask: What do you see in this picture?
- Possible responses:
- clean water, a drop of rain, waves or ripples in the water, reflections of trees
- Congratulate students on the work they have done and explain that on this last day of the Plastics: From Pollution to Solutions unit, their final activity is focused on reflections and ripples.
- Ask: What are reflections, and what are ripples?
- Possible responses:
- A reflection is what you see in the mirror, or in the water.
- A ripple is a wave that travels outward from a single point.
- Tell students that even though the unit is ending today, the problem of ocean plastics does not end today, and neither should their journey from knowledge to action.
- The reflection represents students looking inward at themselves and how they have changed.
- The ripples represent the effects of small actions, like a single drop of water, moving outward into the world and affecting others.
- Orient students to the reflection banner hanging in the room (see Setup for directions). Explain or post directions for how the banner works:
- Top half: Students write or draw at least one individual action they plan to take in relation to plastics.
- Bottom half: Students draw or write one or more collective actions they want to see other people take in relation to plastics.
- Explain that one half of the class will complete the Ripples and Reflections Survey handout while the other half of the class will reflect on the banner with markers.
- After both groups have finished their assigned reflections, tell the groups to trade places until all students have taken the survey and written on the banner.
- Once students have completed their surveys and written on the banner, teachers are encouraged to share their class’ responses, along with the students’ final projects, digitally with the broader National Geographic educator community.
- Conclude the unit with a whole-class discussion about next steps.
- Discussion questions:
- If a member of your target audience did not attend today, what is your plan to reach out to them?
- If a member of your target audience did attend today, what is your plan to follow up with them to check on their progress in completing the Call to Action?
- This is a good opportunity for a final review of the class Know and Need to Know chart.
- What questions about plastics do you still have that were not answered in this unit?

Setup
Ensure that you have ample extra copies of the Final Project Checklist and Rubric on hand for peer review.
Confirm audience attendance for the final publication presentations. Prompt teams to send reminders about timing and logistics as needed based on the outreach teams accomplished in the Choosing an Audience activity.
Step 1: Note that the success of this activity builds on the work of the publishing teams in the Choosing an Audience activity, when teams invited their target audience to a presentation of their published magazine. Ideally, members of their target audiences will be able to attend this session; however, this will not always be possible for all groups. Consider following up with each group’s target audience a few days before this final activity to confirm their attendance. Additionally, inviting school and community members can provide an authentic audience, even if they don’t represent the specific audiences targeted by each group.
Step 2: Hang a long banner across a wall in your room or a hallway at eye level. Draw a dark line horizontally across the paper dividing it in half.
If students will use the template for the Call to Action for Readers handout in their final publication, print it single-sided on two separate sheets of paper, so the two pages can face each other in the published magazine. As in all previous activities, all drafts should be completed in pencil so that revisions can be completed neatly after the peer editing phase in the next activity, Magazine Design Workshop III.

Background Information
Raising awareness about problems is important, but it is not enough. In order to create change, people—individuals, communities, businesses, and governments—must act. Research suggests that the most effective calls to action are highly targeted, with a unique audience, specific place, and observable action. When students participate in authentic, community-based projects, they often experience significant changes in attitude and improved educational outcomes.
Prior Knowledge
- None

Tips & Modifications
Tip
- Step 1: To learn more about best practices for conducting a gallery walk, read How to Use a Gallery Walk.
- Step 1: Determine strategies for handling presentations with limited guests. For example, if multiple publishing teams invited guests who did not attend, prompt them to read each other’s magazines and provide feedback. For teams whose invited guests did not attend, read their magazine and talk to them about next steps:
-
- Do they have a plan to follow up with their target audience and deliver the magazine?
- If they have tried to reach out multiple times and not gotten any response, there are a couple of options.
-
-
- They could escalate their campaign by having other people call on their behalf or report to the news media that they have requested meetings and been ignored.
- They could choose a different target audience with a similar message and reach out to them instead.
-
- Step 2: Learn more about reflective resources and questions for students and teachers:
