Microplastics have been found in the most remote locations on Earth as well as in where we live, work, and play. Despite increasing research focus on microplastics, efforts to inform the public about their omnipresence have lagged. To bridge this gap between research and public knowledge, we developed a museum exhibit with interactive and informative displays that explain what microplastics are, how they are formed, where they are found, and what individuals can do about it. In a partnership between researchers at the University of Michigan (Ann Arbor) and staff at the Dossin Great Lakes Museum (Detroit), the exhibit highlights the impacts of microplastic pollution in the region. Collected survey data revealed that museum visitors were aware of microplastic pollution and are worried about it, that they felt the museum exhibit was helpful and informative, and that they are likely to take simple actions to decrease microplastic pollution.
