How to Impact Your Community with Citizen Science, Even if You’re New to Data Analysis

How does a cell phone discarded into the trash in Seattle make its way to Florida? Further, why does that happen and how can we prevent it? Citizen scientists can help answer those questions.

Citizen science offers regular people ways to join in the process of scientific discovery. When amateur scientists participate in projects that measure air quality, monitor damage from storms, or track where their trash is going, they can help solve problems and shape a better future for their communities and society.

Through citizen science, volunteers contribute to research by providing rich and diverse forms of data that scientists at universities, government agencies, and in the private sector can apply to myriad projects. The process helps scientists save time, money, and effort by generating useful data from around the world. In turn, citizen scientists nurture their curiosity and, particularly in young budding scientists, develop their passions for STEM education.

Consider the cell phone example. Before starting a food supply company, Erin Baumgartner was a researcher at MIT. There, she oversaw a project in which sensors placed in garbage tracked refuse items from Seattle to points across the country. The sensors tracked some trash all the way to Florida.

Now, imagine what scientists might learn if millions of citizens worldwide dropped sensors into their garbage cans? The data could help change our approach to trash disposal.

In this article, we’ll explore how amateur scientists, hobbyists, teachers, and students can help create change by becoming involved in citizen science. We’ll also discuss projects and best practices, provide tips and resources, and help cultivate interest in being a part of the scientific community.

Citizen Science Projects

Citizen scientists participate in thousands of research projects around the world. At, the U.S. government’s official site for citizen science and crowdsourcing, nearly 500 projects are registered. These projects cover an array of fields including animal study, climate and weather, medicine, food, ecology, and many more. Other government agencies, such as the Environmental Protection Agency and the U.S. Forest Service, support their own projects. State, local, and independent organizations offer more ways to become a citizen scientist.

We’ll introduce some projects that are being conducted in various fields nationwide and in the New York area. Each of these projects offers opportunities for volunteers to collect data and participate in studies that are helping to improve our lives and communities.

The Value of Citizen Science

William Redfield was a steamboat captain in the mid-1800s whose fascination with weather led him to become a meteorologist and the first president of the American Association for the Advancement of Science. He also is considered an innovator in citizen science for his work in tracking hurricanes.

Since then, citizen scientists have played an important role in conservation, contributed to Alzheimer’s research, and even found a lost spacecraft. The field of citizen science is “booming,” according to the online magazine Vox, as more and more people are turning their hobbies into beneficial research.

The best part is, citizen scientists don’t need degrees, research grants, expensive equipment, or experience analyzing data to enrich the scientific community. With some common tools (a smartphone or a telescope, a rain gauge or a barometer) and an inquisitive mind, anyone can practice citizen science.
