Models

In this lesson, students build a model showing how water flows through a system and evaluate different management practices to see how they might reduce the amount of marine debris that enters the marine environment. The models in this lesson could be used as a classroom demonstration or traditional lab investigation for students, depending on time efficiency of instructor and students.

This lesson plays on students’ creativity by asking them to design a machine that collects debris in the ocean without impacting wildlife.

This lesson covers different impacts of marine debris on the ecosystems and human communities, including ingestion, entanglement, and our own experiences. Students will complete two activities:

Students will draw connections between land-based debris and its travel to the ocean through exploration and understanding of watersheds. Through these activities, students will:

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.

Students use photographs of regurgitated albatross boluses to perform a “virtual dissection” and analysis, comparing the amounts of prey and non-prey items found in several boluses. They then use what they have learned to create a model of a bolus, with which they can educate others. This activity is available for Grades 6-8 and 9-12, within the "Impacts" unit. 

Students learn about at least two possible impacts of microplastics on the marine environment. They calculate the surface area of rectangular prisms of various sizes and create an argument that the greater surface area of small plastic pieces can potentially accumulate more toxins.

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 construct models of ocean surface currents and winds to explain the dispersal of Japanese Tsunami Marine Debris (JTMD). Then they compare their model to those generated by researchers.

Students use a model to test how air movement affects water movement, and devise a hypothesis about how the direction of air currents affect the movement of ocean surface currents and floating objects. This activity is available for Grades 6-8 and 9-12, within the "Sources and Transport" unit. 

In this lesson, students will collect debris on their school grounds,“x” number of miles from the ocean and compare the quantity of plastic in the sample with a similar sample at the mouth of the river, where it empties into the ocean.

This interdisciplinary lesson centers around a storybook and three related classroom activities. In the story, three children work together to learn about surface currents and the seafaring history of a plastic duck found on a beach. Students engage in reading, writing, and science process skills. This activity is available for Grades 4-5, within the "Sources and Transport" 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. 

The goal of this lesson is to demonstrate what happens when natural disasters collide with inhabited areas. Students have the ability to interact with scientific models to learn about weather/natural disasters.

The goal of this lesson is to demonstrate what happens to animals that get trapped by some kinds of marine debris. Students will experience similar effects to those that happen to animals that get trapped. This activity works well as an engagement activity.
