Teachers become students again at physics data workshop

Editor’s note: Fermilab offers a wide range of STEM educational programs. This article is the first in a multi-part series that highlights some of the opportunities available at the lab.

For the first half of a weeklong workshop at the U.S. Department of Energy’s Fermi National Accelerator Laboratory, a select group of high school teachers put on their “student hats” and learned how to use real-world scenarios to expose their students to particle physics.

They did so at the QuarkNet Data Camp. QuarkNet is a nationally acclaimed science education program, funded by the National Science Foundation and coordinated by the University of Notre Dame. Fermilab, a major contributor to the QuarkNet program since its inception, hosted the program’s annual Data Camp in July.

The camp lasts for a week and draws about two dozen high school teachers, predominantly physics teachers, from across the country. Other high school teachers who are teaching and learning fellows for QuarkNet run the Data Camp and instruct the participants. In addition to the main activities, the teachers participating in the workshop get to see Fermilab and learn from scientists.

For the first few days at the workshop, the teachers worked together in groups to analyze real particle collision data from the Compact Muon Solenoid detector at the Large Hadron Collider. The teachers must use the data — cleaned up a bit to make it easier to use — to figure out particle masses and look for a particular kind of particle collision event. Particles created in the collision decay into other particles, and by finding those post-decay particles, the teachers can infer what kind of event they are seeing.

“They were students for the first part of the week,” said Jodi Hansen, a high school physics teacher from Minnesota and a teaching and learning fellow for QuarkNet who has helped facilitate the program for more than a decade. “We pushed them; sometimes they were uncomfortable, and sometimes they were doing things that were hard for them. A lot of them hadn’t done physics like this before, and this is what physicists who work on the LHC do all the time.”

Spencer Pasero, a member of Fermilab’s Office of Education and Public Engagement, said giving the teachers real datasets that physicists have used provides a more authentic experience, and it teaches them that real data can be messy and ambiguous. One challenge for the teachers is picking out signals, or useful information, from the background noise that clouds real-world data.

“You have to explore and figure out, ‘what’s this really telling me?’” he said. “Are there things that I might be assuming that are not accurate? How do you tell signal and background apart? In a lot of high school labs, there is no background, it’s all signal, and so being able to tease those things apart is useful.”

Putting the teachers into the position of student and asking them to solve problems can be daunting, said Jeremy Smith, Baltimore physics teacher and a teaching and learning fellow for QuarkNet who helps facilitate the data camp. But he and Pasero both said the process is rewarding and leaves the teachers eager to share what they have learned with their students.

“It can be really helpful to experience new topics, new content, new ways of thinking and working, from that student perspective,” Pasero said. “It helps them get into that mindset of, now that I’ve experienced this, and I know what I needed to learn to be able to understand this data, how am I going to give that to my students?”

Emily Rosen, a teacher from Cincinnati and a participant in this year’s data camp, has been teaching for 18 years and has been involved with QuarkNet since the beginning of her career.

For Rosen, analyzing the data challenged her in a way that teaching cannot. The experience gave her an opportunity to solve a complex physics problem and reminded her of what it’s like to be a student.

“As teachers of a subject that is sometimes intimidating and complex, it’s really good to be reminded that the first time a student sees something, it’s not as straightforward as it appears to me,” Rosen said. “It’s just nice to be academically challenged and to remind myself what that feels like, and what working with other people feels like when I’m feeling challenged.”

As the groups of teachers finished their project, they could then collaborate with and learn from other groups that were looking for particles with similar decay products. This collaboration helped the groups of teachers put together unique presentations that focus on the differences between the different groups’ tasks, Hansen said.

“They share with other teachers studying the same decay channel to see what their particle did to make those electrons, or to make those muons, that’s different with different particles,” she said. “We had them look for what was similar and what was different. When they got back together with their particle group, we asked them to point out things that were different from the other particles.”

After the teachers gave presentations about what they learned, they spent the last couple of days discussing ways to use this experience to bring particle physics into their curriculum. In addition to the data camp, QuarkNet provides a vast library of data activities, covering different aspects of particle physics that teachers can integrate into their classrooms.

“For the second half of the workshop, they put their teacher hat back on and focus on thinking about ways that they can implement what they’ve learned into their curriculum,” Smith said.

“Teachers say they don’t have enough time to teach the stuff they already have to, to say nothing of an entire new unit,” he continued. “Rather, the teachers find it helpful to sprinkle these activities throughout the curriculum and do it as an addition to or replacement for something that they already have. They’re weaving particle physics concepts into the whole course.”

Hugo Delgado, a physics teacher from Puerto Rico, said he learned not only about particle physics and Fermilab, but also how fellow teachers use particle physics to construct a diverse and engaging physics curriculum.

Delgado usually works with other science teachers and doesn’t have many opportunities to meet fellow high school physics teachers. During the QuarkNet Data Camp, he got the chance to learn from peers.

“Learning that the difficulties I have as a teacher in Puerto Rico are similar to the ones that people from other places in the United States have, that gave me hope that I was doing things right,” Delgado said. “Also, they gave me ideas for how I can approach particle physics in my classroom.”

Discussing opportunities to bring particle physics into the classroom with other teachers was also inspiring to Rosen.

“Teaching science is like shooting a moving target — because if you’re doing it well, it’s changing — and we should keep up with it and bring it into our curriculum,” she said. “I am deeply appreciative of experiences where I can grow myself so that I can bring that back into my classes.”

QuarkNet Data Camp takes place each July. Teachers who are members of QuarkNet can be nominated by their mentor or QuarkNet staff to participate in the annual camp. There is no cost to attend – all expenses are paid – and the educators receive a stipend for their time.

“Even though it was just one week, I think it has been the highlight of the whole summer,” Delgado said. “I have already started to plan my year, and it’s going to have a great impact on how I approach my class this year.”

Chicagoland has been a stronghold for birds for the past two decades, a recent report showed, and the U.S. Department of Energy’s Fermi National Accelerator Laboratory plays a key role in providing habitat for birds.

The Bird Conservation Network, a group of 21 Chicago-area nature conservation organizations, presented the results of the last 22 years of bird population monitoring during colloquium at Fermilab on July 12. Alongside BCN’s own bird counts, the group presented the data gathered at Fermilab since 1987.

“Fermilab has been preserving and restoring thousands of acres of land, and our findings show that efforts like those are having an incredible impact on birds in the Chicagoland region,” said BCN President Eric Secker. “By managing preserved habitats and prioritizing ecologically sensitive areas, Fermilab has protected threatened species and shown the surrounding community how development and growth can take place in a way that allows birds and natural areas to continue to thrive.”

Much of BCN’s report brought good news about local bird populations. In the Chicago area, 56% of bird species are either stable or increasing, compared to 37% elsewhere in the state. The sandhill crane, a bird that lives near marshes and ponds, has increased in the Chicago area 7.3% annually according to the BCN report, and the Fermilab data shows that sandhill cranes have been seen more consistently, especially since 2012.

Not all bird species are doing well, however. The black-crowned night-heron, for example, has declined 10.5% annually, and its presence at Fermilab became less common in the 2017-to-2021 reporting period.

Bird monitoring and land management has been a part of Fermilab for decades. Prairie restoration efforts at Fermilab began in 1975, pioneered by local biologist Robert Betz. Fermilab has a long history of supporting science-based long history as part of its mission: Founding director Robert Wilson immediately championed the idea when Betz proposed a prairie restoration project. The conservation work over the decades has resulted in about 1,000 acres of restored prairie.

Peter Kasper, a birdwatcher and retired Fermilab employee, began monitoring the birds at Fermilab in the mid-1980s. Eventually, he teamed up with a student from the Chicago Academy of Science who wanted to study the Fermilab birds, leading to a formal bird monitoring program. More than 290 species of birds have been identified on the Fermilab site since monitoring began.

“It’s interesting how it has evolved by individuals pushing for things like the prairie,” Kasper said. “It has been dedicated individuals who have kept that alive, myself included. The only reason we have all this data is because I like watching birds. Working at Fermilab was a golden opportunity for me to combine my physics interests with my birding interests.”

Since then, Fermilab Natural Areas, a nonprofit organization that brings in volunteers to help manage the site’s 2,600 acres of natural area, continues to collect bird data and make the lab more hospitable for birds.

“The volunteer group gives people a way to interact with the natural areas to really feel ownership of them,” said Fermilab ecologist Wally Levernier. “If a steward is removing the last pieces of buckthorn in their woodland and restoring the understory, and they see how it started versus what it is now, it’s a huge sense of accomplishment.”

Although both the BCN survey and the Fermilab survey have lasted for decades, the two approaches provide different information about bird populations. BCN collects data twice per year during the breeding season and counts every bird that can be seen or heard. The Fermilab surveying program, in contrast, collects data every week of the year and only records whether or not a species is present. Since the Fermilab survey is year-round and weekly, it shows when migrating birds leave and come back throughout the year.

The Fermilab site was designated a National Environmental Research Park in 1989, one of only seven in the United States. It features many types of habitats typically found in Illinois, including grasslands, woodlands, wetlands, savannas, lakes and agricultural fields.

There are 12 spots throughout the Fermilab site where birds are monitored as part of BCN’s breeding bird survey, said Dave Spleha, who monitors birds for both Fermilab Natural Areas and BCN. When monitoring birds, Spleha walks to a particular point, waits a few minutes for birds to settle down after being disturbed, and begins counting the birds by either sight or sound within 75 meters for five minutes. Other bird monitoring throughout the year is less structured and takes place in random locations.

When gathering and analyzing bird population data, Spleha stresses the importance of species diversity.

“Diversity is one of the key factors,” he said. “If you have 20 breeding birds, and they’re all the same species, that’s good. But if you have 20 birds and there’s three different species, that’s better.”

The effort to make Fermilab’s natural areas more amenable to birds is ongoing. One such project to encourage the grasslands on Fermilab’s Eola Road involves comparing the use of prescribed fire on one side of the road and mowing the other side of the road to clear out larger plants. In the most recent experiment on Eola Road, relatively narrow strips of grass are mowed in different years to vary the height of the plants in each strip.

The Eola Road grassland is important for certain species, like the declining bobolink and Henslow’s sparrow, but brush and trees provide perches for hawks to hunt the grassland-nesting birds.

“Part of what we’re doing is researching what is most effective on site,” Levernier said. “Our site might be different from the next-door neighbor, but we can pass that information along and say what we’ve learned to help others along the way.”

In contrast, when managing the shrubland on the east side of Fermilab, the team found that mowing hasn’t produced the proper vegetation structure for shrubland. Now, volunteers improve the shrubland by clearing all non-native plants by hand.

“That’s a time-intensive effort,” Levernier said. “We’re taking longer, but hopefully getting better habitat in the long run.”

The population of ospreys, a bird of prey, is one success story, with three nesting sites at Fermilab, Spleha said. Over the past 15 years, 73 ospreys have grown up at Fermilab; last year, there were nine young ospreys, the most ever in a year.

As weather patterns change and the suburbs of Chicago see more development, Spleha said providing a habitat for birds has become more crucial.

“Fermilab is right in the middle of a residential area,” he said. “If we don’t have a good, quality environment for these birds, there’s not going to be anything around here. This is just a little chunk, but it gives these birds a chance to breed in this area, and it keeps them one step away from extinction.”

By their nature, high-energy particle accelerators take up a lot of space while leaving plenty of open space for wildlife, Kasper said.

“It is a unique place, and it’s a model for how technology and wildlife need not be incompatible,” he said. “I think there’s something significant about the fact that you have one of the most advanced technological apparatuses in the same location as eagles and ospreys.”
