Two simple laboratory experiments for addressing the issue of microplastics in the aqueous environment in science teaching are developed. Extraction of microbeads from cosmetic products using a coffee pad machine makes students aware of the potential emission of microplastics into the environment by using these products. Density separation of microplastic particles from beach sediment samples on the other hand demonstrates the difficulty of dealing with the problem once the particles have entered the environment. Using the low-cost experimental setup facilitates integration of the microplastics' topic into laboratory teaching making science lessons vivid and more interesting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
