Environmental Explorers program brings public health to kids’ backyards

An innovative online summer course empowers budding environmentalists nationwide to tackle local public health challenges, fostering informed and engaged community leaders.

This summer, a group of middle school students from across the country is diving into environmental health topics thanks to a free, self-paced, online program from the Brown University School of Public Health.

Launched in June 2025, the program, called the Environmental Explorers School, was created by the Community Noise Lab with students from the Health Equity Scholars program. The online summer course modules cover topics from air and water quality, to noise pollution and public transportation. The curriculum includes short video lectures, quizzes and hands-on community activities designed to help students connect their learning to their own neighborhoods. The goal is to introduce young students to the world of public health and, in particular, to environmental health.

“Typical science classes only have room to cover specific earth or physical science materials, but there is so much more in science especially looking at environmental health,” said Jacqueline Larson GS, a Health Equity Scholar who co-developed the program. “Learning about the different issues, like illegal dumping or water contamination, can lead to exposure to new careers and job interests. It helps students become more rounded in the sciences, and could potentially become an interest they pursue, or even study in college.”

Currently in a pilot phase with 20 students, the program has attracted participants from states including California, Kentucky, Louisiana, Mississippi, Missouri, Massachusetts and Rhode Island. Organizers hope to expand the program and work with schools to offer it year-round.

“Middle school is such an interesting period in our lives,” said Erica Walker, assistant professor of epidemiology and founder of the Community Noise Lab. “Middle schoolers are old enough to think deeply about anything and everything, but they are often viewed as too young to participate meaningfully in their communities. We have created an opportunity that allows them to do both.”

The program covers 25 environmental health topics including air quality, food deserts, the importance of greenspaces, illegal dumping, overfishing, carbon footprints and public policy around these issues. Each module, which students complete at their own pace, features short, pre-recorded lectures. The modules conclude with a quiz and a community engagement project, such as using a noise-measuring app or conducting a local greenspace inventory.

Thirteen-year-old Chloe McDougal from Mississippi—who completed all the quizzes with perfect scores—wrote about her experience in the program in an essay that will be published in the Jackson Advocate. McDougal’s essay points to the program’s ethos of helping young learners become knowledgeable about environmental challenges and inspiring them to take action.

“When I joined a local park clean-up crew, I didn’t expect to feel so connected to the land and the people around me,” McDougal said. “We picked up trash, cleared trails and planted native plants. It was hard work, but knowing I was helping preserve a space that many families, children and seniors rely on for exercise and relaxation made it all worth it.”

Along with merit badges for completing modules, students in the program can earn points that can be redeemed at the Brown University Bookstore. Those who complete all modules receive a certificate of completion and are invited to a virtual graduation event.

The online program runs through October and will re-open next June.

“Our program fills a unique need,” Walker said. “If you read the headlines, you'd think that we should be afraid of pretty much everything—from the air we breathe to the food we eat. With these students, we aim to replace fear with knowledge, while encouraging them to take a leading role in their communities.”
