NEW YORK — The fish, glassy-eyed and inert, had been dead for decades. Yet its belly held possible clues to an environmental crisis unfolding in real time.
Forceps in hand, Mia Fricano, a high school junior, was about to investigate. She turned over the fish, a bluegill, and slid in a blade, before extracting its gastrointestinal tract. Then, she carried the fish innards to a beaker filled with a solution that would dissolve the biological material, revealing if there were any tiny particles of plastic — known as microplastics — inside.
Mia and two other high schoolers working alongside her in a lab this spring were part of a program at the American Museum of Natural History designed to give young people hands-on experience in professional science. Called the Science Research Mentoring Program, or SRMP (pronounced “shrimp”), the program enrolls roughly 60 high school juniors and seniors each year who collaborate with scientists on a research project.
Mia and her peers were matched with Ryan Thoni, an ichthyologist and curatorial associate in the museum’s division of vertebrate zoology. Thoni’s project to gather information on when and how microplastics began to enter the environment relied on the museum’s vast collection of fish specimens dating from more than a century ago — some 3.2 million in total.
Concern about the tiny pieces of plastic debris has grown in the last few years, along with early-stage research on the health risks they pose. The particles are found in human blood, breast milk and even the brain — and in animals, including, as it turned out, nearly all the fish in Thoni’s lab.
“It was kind of shocking to see just how many we did find,” Mia said later. “We weren’t expecting to find more than two to three per fish but in some fish, we would find over 15.” Specimens from the 1970s or earlier were less likely to contain high levels of microplastic, more than three or so pieces, and fish near urban centers seemed to have more of the plastics, on average, than fish from less populated areas.
“It really does make you realize just how much the environment has been affected,” said Mia. “There hasn’t been a lot of research on it yet,” she added. “Our project might be able to help future people who are also doing research on microplastics.”

SRMP, started in 2009, is operating at a time when the federal government is eliminating fellowships and other support for early career scientists, and defunding scientific research broadly. That both amplifies the need for, and complicates the work of, programs like this one, said Amanda Townley, executive director of the nonprofit National Center for Science Education. Over the last 15 years in particular, such programs have played a big role in giving students a chance to do the kind of applied science that is rarely available in K-12 classrooms because of money and time constraints, she said.
“Museums, university extensions, sometimes libraries, have really done this tremendous job of creating spaces for high school and younger students to engage with scientists doing science,” said Townley. “Those museums, libraries and universities are all under attack.” She added: “We’re going to see a generational impact.”
While the American Museum of Natural History has received some federal government funding, the SRMP program’s money comes from private foundations and individual donors, with additional support from the New York City Council. Students in SRMP participate in a summer institute in August, when they learn basics like how to investigate research questions. Then they spend two afternoons a week during the school year on their projects.
Each student receives a stipend, $2,500 over the course of the year. “It’s really important for high school students to know their time is valuable,” said Maria Strangas, the museum’s assistant director of science research experiences. “They are doing something here that is really useful for the researchers; it’s an education program, but they aren’t the only ones who are benefiting.”
Students from New York City schools that partner with the museum can apply, as well as those who have participated in programs with the museum in the past. SRMP has also spawned a network of about 30 similar programs across the city, with institutions including Brooklyn College, Bronx River Alliance and many others participating.
In the lab on the sixth floor of the museum, Mia, who attends the New York City Museum School, cleaned out a beaker, while Yuki Chen, a senior at Central Park East High School, sat at a metal table, dissecting a pike. Thoni inserted a slide containing material harvested from one of the fish under a microscope, and pointed out a few microplastics, which looked like threads.
Freyalise Matasar, a junior at the Ethical Culture Fieldston School in the Bronx, plucked a white sucker fish from a jar. She said SRMP had altered her career trajectory. Before the program, she was considering studying journalism in college, but her experience this year persuaded her to focus on engineering and data science instead.
“I have totally fallen in love with science,” she said. “It’s been an amazing experience to see what professional science looks like — and more than just see it, to be a part of it.”
Freyalise said she wanted to build those skills in order to help fight climate change, perhaps by working on weather models to predict climate risks and ideally spur people to action. “It’s the biggest problem faced by our generation. It’s inescapable and unignorable, no matter how much people try,” she said. “It’s everyone’s responsibility to do what they can to fight it.”

Microplastics contribute to climate change in several ways, including by potentially disrupting oceans’ ability to sequester carbon and by directly emitting greenhouse gases.
Interest in climate science among young people is growing, even as the federal government tries to zero out funding for it. Other climate-related topics SRMP students explored this year included the climate on exoplanets, the ecology of sea anemones and aquatic wildlife conservation in New York City.
Sometimes the fish dissections were gross: Mia, who plans to study biology and machine learning in college, sliced into one large fish to find poorly preserved, rotten innards — and a major stink. Sometimes they provided a lesson beyond pollution: Yuki identified a small pickerel inside a larger one. (Pickerels prey even on members of their own species, the students learned.)
The scientists in the program, most of whom are postdoctoral fellows, are trained on how to be effective mentors. “Scientists are often not trained in mentorship; it’s something that people pick up organically seeing good or bad examples in their own lives,” said Strangas. “A lot of it comes down to: ‘Think about the impact you want to have, think about the impact you don’t want to have, think about the power dynamic at play, and what this student in front of you wants to get out of it.’”
Thoni earned rave reviews from the students, who said he ensured they understood each step of the research process without being patronizing.
Thoni’s next steps include working to publish the microplastics research, which could earn the students their first co-authorship in a scientific journal. “Aside from forgetting to put on gloves,” he said in a playful jab at one student, “they can operate this machine on their own. They do science.”
