Physical Science

This brief reading passage discusses types, sources, and impacts of marine debris, including an anecdote about recovery from Hurricane Katrina in Mississippi.

Students will find creative new uses for common debris items like bottle caps. 

Students will extend their experience in the cleanup by discussing and analyzing ways to prevent marine debris from entering the environment, including Reduce/Reuse/Recycle strategies, Personal habits; Policy change, etc. Using a 4-corners style activity, students will separate debris materials (from the debris deck) into categories for Reduce/Reuse/Recycle/Other.

This lesson includes discussions and activities meant to help students process and analyze their cleanup experience. Students will reflect on the strangest trash item collected and tell the story of its journey to the cleanup site using a medium of their choice (writing, drawing, skits, etc.).

Students will plan, prepare for, execute, and report back on a cleanup in their local area.

Through discussion,vocabulary, and hands-on activities, students will learn about debris composition and what happens to trash once it enters waterways. Students will also explore the formation of mircoplastic through a simple, hands-on activity using a piece of paper.

An introductory lesson using discussion, vocabulary, and critical thinking activities to understand land- and ocean-based sources of marine debris.

Using cards to represent each type of debris identified on the Ocean Concervancy's list of items found during cleanups, students will discuss each debris type and arrange themselves in order of most commonly found. (Debris Deck cards included.)

Students will pick out the hidden images of marine debris amid a graphic of a beach scene.

Plastic pellets (also called “nurdles”) are small pre-production pieces that are shipped around the world to factories that melt them to produce a variety of products. Pellets are often lost during transit, and because they float can be found throughout the ocean and on beaches everywhere.

Students focus on one characteristic of some marine debris – the “loop” shape – and learn how marine debris items with this shape negatively impact sea lions. This activity is available for Grades 4-5, within the "Impacts" unit. 

Students use a model to make observations about how an animal entangled in marine debris might be affected. Then they play a game that demonstrates how plastics in the ocean can be ingested by animals. This activity is available for Grades 4-5, within the "Impacts" unit. 

Students relate the location of plastics in the water column to the feeding behavior of various marine organisms. They discuss how marine debris can cause problems for different animals inhabiting a variety of ocean depths. This activity is available for Grades 4-5 within the "Impacts" unit, and for Grades 6-8 and 9-12 within the "Composition and Abundance" unit. 

Students use a sampling protocol to collect, sort and quantify (by number or by weight) marine debris collected from a beach. The 5 Gyres lesson provides data cards for macro and micro marine debris. This activity is available for Grades 4-5, 6-8, and 9-12, within the "Composition and Abundance" unit. 

Students explore a local riverbank or beach and carry out a survey to assess human impacts on the area. Students analyze and share their findings. This activity is available for Grades 4-5, within the "Composition and Abundance" unit.
