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 will follow the engineering design process to explore solutions to the overwhelming plastic packaging problem. They will develop sustainable designs that will consider alternatives to plastic packaging in items like juice boxes, plastic straws, bin liners, and single-use take-away/take-out containers.

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 describe the life cycle of man-made products that include or originate from plastic to 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 lifecycle of the product.
