About 70% of our planet is covered by oceans and seas: large, full of life and mysterious.
They are a source of food, way of transportation, oxygen producer, and more.

But the sea is in danger: overfishing, plastic waste, acidification, species extinction.
We need to better understand the marine life and deal with it in a sustainable way, because our life is closely linked to the sea. If it is sick, we cannot stay healthy.

After reviewing the many products that can be made from corn and soybeans, students will create biodegradable plastic using corn and soybean ingredients. These ingredients are as simple as cornstarch and vegetable (soybean) oil!  Source: https://grownextgen.org/media/pages/curriculum/meet-the-bean/fun-and-games-with-soybeans/7e281dd28b-1565628888/biodegradable-soy-plastic.pdf

Students act as engineers to learn about the strengths of various epoxy-amine mixtures and observe the unique characteristics of different mixtures of epoxies and hardeners. Student groups make and optimize thermosets by combining two chemicals in exacting ratios to fabricate the strongest and/or most flexible thermoset possible.

Polymers are a vital part of our everyday lives and nearly all consumer products have a plastic component of some variation. Students explore the basic characteristics of polymers through the introduction of two polymer categories: thermoplastics and thermosets. During teacher demos, students observe the unique behaviors of thermoplastics. The fundamentals of thermoset polymers are discussed, preparing them to conduct the associated activity in which they create their own thermoset materials and mechanically test them. At the conclusion of this lesson-activity pair, students understand the basics of thermoplastics and thermosets, which may entice their interest in polymer engineering.

Geographic information systems (GIS), once used predominantly by experts in cartography and computer programming, have become pervasive in everyday business and consumer use. This unit explores GIS in general as a technology about which much more can be learned, and it also explores applications of that technology. Students experience GIS technology through the use of Google Earth on the environmental topic of plastics in the ocean in an area known as the Great Pacific Garbage Patch. The use of this topic in GIS makes the unit multidisciplinary, incorporating the physics of ocean currents, the chemistry associated with pollutant degradation and chemical sorption to organic-rich plastics, and ecological impact to aquatic biota.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water. The plastic will attract the surface of the water into a visible bump.

Students are introduced to polymer science and take on the role of chemical engineers to create and test a plastic made from starch. After testing their potato-based plastic, students design a product that takes advantage of the polymer’s unique properties. At the end of the engineering design process, students present their product in a development “pitch” that communicates their idea to potential investors.

Students take part in a hypothetical scenario that challenges them to inform customers at a local restaurant of how their use and disposal of plastics relates/contributes to the Great Pacific garbage patch (GPGP). What students ultimately do is research information on the plastics pollution in the oceans and present that information as a short, eye-catching newsletter suitable to hand out to restaurant customers. This activity focuses on teaching students to conduct their own research on a science-technology related topic and present it in a compelling manner that includes citing source information without plagiarism. By doing this, students gain experience and skills with general online searching as well as word processing and written and visual communication.

The Great Pacific Garbage Patch (GPGP) is an intriguing and publicized environmental problem. This swirling soup of trash up to 10 meters deep and just below the water surface is composed mainly of non-degradable plastics. These plastic materials trap aquatic life and poison them by physical blockage or as carriers of toxic pollutants. The problem relates to materials science and the advent of plastics in modern life, an example of the unintended consequences of technology. Through exploring this complex issue, students gain insight into aspects of chemistry, oceanography, fluids, environmental science, life science and even international policy. As part of the GIS unit, the topic is a source of content for students to create interesting maps communicating something that they will likely begin to care about as they learn more.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Global urbanization is driving a flood of plastic pollution, and we desperately need ways to break these plastics down. And plastic-eating insects may be able to help. Such insects leverage their gut microbes to degrade plastic polymers, but little is known about how insects acquired this ability. To learn more, researchers examined the mealworm gut microbiome’s response to different diets. The bonds in synthetic plastic polymers can resemble those in natural polymers. Polystyrene, for example, has bonds like lignin, a polymer found in all vascular plants. So, the researchers fed mealworms polystyrene or corn straw, which is high in lignin. Neither experimental diet had a negative effect on the mealworms’ survival compared to a normal cabbage diet. Both polymer-heavy diets led to similar gut microbial community structures, metabolic pathways, and enzymatic profiles..."

After watching a short online video that recaps the enormous scale of accumulating plastic waste in our oceans, student teams are challenged to devise a method to remove the most plastic microbeads from a provided commercial personal care product—such as a facial cleanser or body wash. They brainstorm filtering methods ideas and design their own specific procedures that use teacher-provided supplies (coffee filters, funnels, plastic syringes, vinyl tubing, water, plastic bags) to extract the microplastics as efficiently as possible. The research and development student teams compare the final masses of their extracted microbeads to see which filter solutions worked best. Students suggest possible future improvements to their filter designs. A student worksheet is provided.

This lesson will introduce students to plastics and microplastics, allowing them to identify various categories of microplastics and how they can reduce the amount of plastic that is used. Students will learn how the consumption of plastics impacts the environment.

There is good reason to invest in tourism in Zanzibar. In 2019, it was expected that over half a million tourists would visit the island, which is only half the size of Funen island in Denmark. Tourists bring in money and growth, but research shows that, for example, Zanzibarians only have 11% of managerial jobs in restaurants and only 20% of tourism revenue goes to the local community, while 53% disappear from the island.

Danish:
Der er god grund til at investere i turismen på Zanzibar. I 2019 forventede man, at over en halv million turister ville besøge øen, som kun er halvt så stor som Fyn. Turisterne bringer penge og vækst, men forskningen viser, at zanzibarianere for eksempel kun har 11% af lederjobs på restauranter og kun 20% af indtægterne fra turismen går til lokalsamfundet, imens hele 53% forsvinder væk fra øen.

"Plastics have countless uses. However, the mismanagement of plastic waste has resulted in widespread ocean pollution, which could persist in the marine environment for hundreds of years. But growing research suggests that certain microorganisms could be harnessed to break down this waste. The key is verifying whether plastic-degrading microorganisms actually occur in the biofilms that colonize the surfaces of plastic particles, or the “plastisphere", and understanding their temporal characteristics. Recently, researchers found a high diversity of microbes that varied in their community composition over time when cultured on different types of polyethylene terephthalate (PET) plastic. They also found evidence of PET degradation by these microorganisms based on a combined proteogenomic and metabolomic approach, which confirmed that two newly identified isolates from these communities are able to degrade PET using different pathways, one of which may be novel..."

400 million tons of plastic is produced every year, 36% of which is designed for single use or packaging. Of that number, only 9% is recycled. It’s fair to say that plastics are everywhere, including the ocean. In fact, approximately 13 million tons of plastic enters oceanic currents annually. Plastic has become a pillar of modern life. It’s going to take a deep, transformational change in humanity’s consciousness and activities regarding the ocean to break the plastic pattern.

We believe this is possible! But we need your help. By relating socio-economic and scientific concepts such as watershed and ocean currents, food chain interactions, and the greenhouse gas effect, youth will learn the history of plastic, how it transformed our consumer habits, how it harms ocean health, exacerbates the current climate crisis, and how they can protect our ocean from further plastic pollution and restore the ecosystems already affected.

Through this education kit’s activities, students will be given the knowledge, tools, and skills to break their plastic pattern and become leaders of change – and this all starts in your classroom.

A group of Scripps graduate researchers recently returned from a 20-day expedition to the ŇGreat Pacific Garbage Patch,Ó a little-studied remote ocean region where plastic debris accumulates. Join Miriam Goldstein, chief scientist on the cruise, and colleagues Pete Davison and Chelsea Rochman, as they discuss the garbage patch, why itŐs there, and how they are exploring and analyzing the problem of plastic in the North Pacific Ocean.

As the name suggests, microbeads are very small (microscopic) beads of plastic. Since they are particles of less than 1mm, they are almost impossible to capture as they enter household drains. This leaves these small, solid balls of plastic to enter our aquatic ecosystems where they are ingested by organisms and accumulated within the food web.  In this activity, students are challenged to design and construct their own device to extract microplastics from cosmetic products such as facial cleansers, body wash, and toothpaste.

Students examine the nature of the problem and work collaboratively to create solutions to the issue of nurdles becoming evermore present in our oceans. Nurdles are small plastic resin pellets which are used to make many of the plastics we use every day. Unfortunately, they end up where they are not supposed to and cause a wide range of problems.  Nurdle Know-How is a series of activities that will ultimately prepare students to design and build a nurdle capture system to clean up their local bay, harbor, or coastal waters.

In this investigation, students design and create a Recycling Sorting Machine to eliminate the amount of waste that is incorrectly being sent to landfill. Students use basic resources (recycled and/or reused items in the classroom, home, or their community) to engineer a solution to the growing problem of waste in our schools.

In this investigative assessment, students describe the life cycle of man-made products that include or originate from plastic and other materials and evaluate how they may impact the environment. Students use a basic life cycle assessment – similar to assessments used by process engineers – that allows them to identify and order the different steps in the life cycle of a product. Using their analyses to compare the impacts of different products, students develop ideas to reduce the environmental impact of the production process or the lifecycle of the product.
