Class Discussion

This guide is designed for educators in both formal and informal education situations. It is a regional introduction to three main categories of marine debris: litter; derelict or abandoned boats; and lost or abandoned commercial and recreational fishing gear. Appropriate for grades 5-8.

Turning the Tide on Trash is a learning guide on marine debris. This set of lesson plans and background information introduces educators, students and researchers to the topic of marine debris. The interdisciplinary education guide is designed to provide maximum flexibility in the classroom: it can be used as a stand-alone teaching tool or to supplement work in other subject areas.

Students will learn about the efforts of private organizations and individuals, both locally and nationally, to prevent marine debris and take steps to become involved in a stewardship activity.

As a class, students organize and conduct a cleanup of a local beach, lake, or stream. Students keep track of the types and amounts of trash picked up and analyze this information in the classroom. As a class, students discuss the marine debris problem in their community and consider ways to prevent it.

Students will develop map skills by locating various nations on a globe or map, and by identifying various oceans. As a class, students discuss how an international treaty about marine pollution (MARPOL Annex V) regulates the disposal of garbage at sea.

Students complete a form that requires them to make decisions about how severely different types of marine debris affect animals, people, vessels, and habitat. As a class, results are totaled and analyzed to determine which types of marine debris are most harmful to the different categories.

Students perform an experiment in which they wrap a rubber band around their fingers and across the back of their hand and try to disentangle themselves. As a class, students discuss their thoughts and reactions and relate to real animals. Older students will write a short story about an entangled animal.

Students listen to descriptions of marine animals and then identify marine debris items that could harm them.

Students will observe and record litter they see in their neighborhood, reflect on how the litter came to be there, then make predictions on how the littered items might make their way to the ocean. Students will compare the litter they have observed with data collected during the International Coastal Cleanup.

Over the span of a week, students keep a log of the types and amounts of trash they generate, and how they dispose of that trash. Students also learn which items were (or could/should have been) recycled, and which items could become marine debris.

Students learn about different trash items and define “marine debris” through a discussion about these items. Students then categorize debris and use statistics and graphing to describe the types and amounts of marine debris that are found each year.

Students perform an experiment to learn how different types of debris break down in the environment (degrade) and how weather and sunlight affect the rate of degradation.

Students will first define marine debris, discuss its possible impacts, and then sort household trash items into different categories to learn about different sources of marine debris. Older students then use statistics and graphing to better understand the types of marine debris that are collected each year.

Team-building/active activity where students use verbal directions to guide blindfolded classmates through an obstacle course, simulating navigation around abandoned and derelict vessels.

Research-based role-playing activity where students identify and investigate stakeholders on the issue of abandoned and derelict vessels.
