Grade 6-8

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 extract microplastic beads from personal care products, explore ways microplastics get into the ocean, and learn about a researcher who studies microplastics. This activity is available for Grades 6-8, within the "Sources and Transport" 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. 

Students read a true story about bath toys that fell off a container ship and washed up on beaches around the world. Using a world map, they locate and record the dates and places where the toys were eventually found.

This activity will serve as a catalyst for students to derive connections between their actions and the impact on the environment. Students will observe marine debris from around the world, collect their own trash data around school, and use technology to further research. Once the data can be compared, students will communicate their findings in a group setting.

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.

Students perform an experiment to learn how different types of debris break down over time and how they are their degradation is affected by environmental conditions. This activity is available for Grades 6-8 and 9-12, within the "Composition and Abundance" 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. 

There is a great deal of information and misinformation about how much marine debris exists in the open ocean and how it is distributed. We often hear that “The Great Pacific Garbage Patch is twice the size of Texas”, but what exactly does that mean? Students will read and discuss the article “Pacific Ocean 'garbage patch' exaggerated, new analysis asserts”.

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. 

In this activity, students explore contents of ‘beach boxes’ in groups at tables, sorting contents into “marine debris”, “NOT marine debris” and “not sure”. This activity is available for Grades 4-5, 6-8, and 9-12, within the "Composition and Abundance" unit. 

After creating the masks, take the opportunity to spread the message by sharing what you’ve learned. Post the faces in the hall and write out messages, put them on the stage and share their messages with the school, or use them to present what was learned to the larger community at a local event!

This lesson will begin with an introduction to the mosaic technique and then students will create the background (skin) of the plastic and earth masks.

Students will explore the concept of packaging, both what it has been and what it is. Then they will consider how modern packaging is affecting the environment and what they can do about it.
