STEAM (36)
STEAM stands for Science, Technology, Engineering, Arts, and Mathematics. These are study subjects in which U.S. pupils are generally not at par with their peers in other developed countries. That reduces our chances of finding timely solutions to the dire crises that face our planet. It also diminishes the chances for the U.S. economy to remain competitive.
More people already know the STEM abbreviation. Some states and communities are now implementing STEM education programs. Many experts believe that Art education is important, too. Scientific studies have shown that STEM students and professionals who attended art classes are more likely to find crative solutions to new problems.
Mountain monarchs inspired Wanda DeWaard’s legacy of citizen science

Successful Smokies monarch tagging project is a product of the people
Every winter, way up in the oyumel firs in Mexico’s high elevation forests, millions of North American monarch butterflies that have traveled from as far north as Canada cluster in colonies to overwinter before flying north again to lay eggs in spring. Tens of thousands of monarchs might adorn a single tree like a papery gown, sometimes weighing it down enough to break off branches.
To get to the oyumel forests several miles above sea level, which provide a perfect microclimate for the weary travelers, they migrate south using different aerial paths, or flyways, that merge together over Central Texas. This migrating generation can live up to nine months and might travel anywhere from 1,000-3,000 miles to the forests they seek, yet have never been to. Mysteriously, they find their way and sometimes even make it to the exact tree where their ancestors four or five generations back once clustered.
Monarchs are the only butterfly that makes a long two-way migration. Despite much research on the species, science still hasn’t fully unraveled the secrets of their incredibly accurate homing system. This makes them one of the true marvels of the natural world.
A tagged monarch feeds on nectar in the Great Smokies before joining the migration to Mexico for the winter.

WASHINGTON — The green floater, a freshwater mussel native to the waters of Southern Appalachia, is now formally considered at risk of extinction due to the loss and fragmentation of its aquatic habitat.
The U.S. Fish and Wildlife Service determined the green floater, historically found in 10 eastern U.S. states, is likely to become endangered due to existing and emerging threats. The service is proposing to list the mussel as threatened under the Endangered Species Act.
The green floater is still found in its native range in North Carolina, Tennessee, Virginia and West Virginia. It is considered locally extinct in Alabama and Georgia.
While the species has strongholds in places, green floaters are rare in nearly 80 percent of the watersheds where they naturally occur. More than 75 percent of the nation’s native freshwater mussel species are endangered or threatened, considered to be of special conservation concern, or presumed extinct, according to USWFS.

Etnier left behind a legacy of research and ambitious students
KNOXVILLE — Dr. David Etnier, a professor at the University of Tennessee internationally known for his research on freshwater fishes and caddis flies, died May 17 at the age of 84.
Etnier, known as “Ets” to his students, joined the UT faculty in 1965 and retired in 2001. Three aquatic insect species he helped discover are named after him, and those are just three of the more than 410 insect species he helped discover.

‘It’s very good for the soul.’ Bo Baxter and Conservation Fisheries focus underwater to save our Southern fishes.
This is the latest installment of an occasional series, Hellbent, profiling citizens and organizations who work to preserve and improve the Southern Appalachian environment.
KNOXVILLE — For more than 35 years, an obscure nonprofit headquartered here has grown into one of the most quietly successful champions of ecology and environmental restoration in the Eastern United States.
Conservation Fisheries, which occupies a 5,000-square foot facility near the Pellissippi State University campus on Division Street, has spent nearly four decades restoring native fish populations to numerous waterways damaged years ago by misguided governmental policies.
In fact, the mid-20th century saw wildlife officials frequently exterminating key aquatic species to make way for game fish like trout.
“It was bad science, but it was the best they had at the time,” said Conservation Fisheries Executive Director Bo Baxter. “A lot of the central concepts of ecology, like food webs and communities, were not developed back then.”

How to use free satellite data to monitor natural disasters and environmental changes
This story was originally published by The Conversation. Qiusheng Wu is assistant professor of geography and sustainability at University of Tennessee.
KNOXVILLE — If you want to track changes in the Amazon rainforest, see the full expanse of a hurricane or figure out where people need help after a disaster, it’s much easier to do with the view from a satellite orbiting a few hundred miles above Earth.
Traditionally, access to satellite data has been limited to researchers and professionals with expertise in remote sensing and image processing. However, the increasing availability of open-access data from government satellites such as Landsat and Sentinel, and free cloud-computing resources such as Amazon Web Services, Google Earth Engine and Microsoft Planetary Computer, have made it possible for just about anyone to gain insight into environmental changes underway.
I work with geospatial big data as a professor. Here’s a quick tour of where you can find satellite images, plus some free, fairly simple tools that anyone can use to create time-lapse animations from satellite images.
Knox County mayor honors women leaders in STEAM all month
KNOXVILLE — Knox County Mayor Glenn Jacobs is observing Women’s History Month throughout March by sharing videos each Wednesday highlighting time spent in different Knox County Schools’ Science, Technology, Engineering, Art and Math (STEAM) classrooms taught by female teachers.
The March 15 video features a visit with South Doyle High School STEM/Computer Science and 2022 KCS Secondary Teacher of the Year Katie DeVinney who was teaching a class on the principles of advanced manufacturing and practical design.
“I hope out of courses like this, that young women are able to see the opportunities available in sectors of the economy like advanced manufacturing and hopefully pursue those,” Jacobs said in a press release.
DeVinney is a 10-year educator who began her career as a foreign language instructor but was inspired by her husband who started the Robotics program at South Doyle High School, to switch paths.
“I just love it. It’s so much fun to see the excitement in kids when they get to take something that they designed on this computer and then hold it in the real world. It’s the coolest process I have ever seen so that’s kind of why I do it.” DeVinney said.
Mayor Jacobs said celebrating women in STEAM is important for young girls because it shows them that women can succeed in technical fields — industry typically driven by men.
The mayor has already shared his visit with Hardin Valley Elementary STEM Educators Jessica Everitt and Jana Yra and his visit with West Valley Middle science teacher Bethany Saunders.
Later this month, he will share visits with Gibbs Middle School Art Teacher Dorothy Verbick and STEM Teacher Lauren Downs; as well as Karns Middle School Math Teacher Rebecca Layton.

Updated March 2023 with notes from a reader:
My name is Allison, and I am a teaching volunteer with Students For Research. I am reaching out because our class found your website very useful while researching STEM resources that can help students discover the various aspects of science, technology, engineering and math. Many of our current students are interested in learning more about how topics associated with STEM work, especially in relation to online research, either for school or for their future careers. Your website ended up being featured by our students, so we wanted to notify you and say thank you!
As a part of the assignment, one of our students, Becky, did some research on her own time and found this informative page for more STEM using this resource. The team found it helpful as it provided guidance on how libraries can introduce children to STEM and continue to provide resources as they progress through their education.
I was hoping you would be able to include this resource on your website, even if it's only for a short time. I think your other visitors might find it helpful, and it also helps our group of students cite appropriate resources and stay engaged whenever outreach yields positive feedback everyone can see. Please let me know if you would be willing to add it so I can share the exciting news with Sophie and the rest of her fellow students. I appreciate your help!
KNOXVILLE — What do environmental, social and economic sustainability have in common?
There are numerous ways to answer that question, but for those who pay close attention to education or economics it’s an accepted fact that the future belongs to societies that invest heavily in STEM (Science, Technology, Engineering and Mathematics).
That’s why educators at all levels are pushing students towards those subjects at every opportunity, as was evidenced Jan. 21 at Big Orange STEM Saturday (BOSS) at the University of Tennessee.
About 150 high school students picked from communities across East Tennessee spent much of their Saturday at John C. Hodges Library, getting a first-hand taste of what awaits them should they choose to pursue careers in STEM through the UT system.

Hellbent Profile: Amber Parker brings nature to the people
Written by JJ Stambaugh
Ijams Nature Center Executive Director Amber Parker poses with opossum Opal. She was an Ijams animal ambassador for more than three years. “She came to us after her mother was hit by a car and Opal would fit in the palm of your hand. Sadly, Opal passed away earlier this year. Opossums live short lives, usually about three years, so Opal had a nice long one by opossum standards. She was beloved by all and we miss her.” Courtesy Ijams Nature Center
Each year more than 600,000 people visit Ijams Nature Center
This is the second installment of an occasional series, Hellbent, profiling citizens who work to preserve and improve the Southern Appalachian environment.
KNOXVILLE — On any given day, the parking lot at Ijams Nature Center in South Knoxville is packed with cars, trucks, and buses as folks of all ages flock to hike, climb, swim and paddle its 300-plus acres of protected wildlands.
Making sure the center’s 620,000 or so annual visitors have a positive experience interacting with Mother Nature requires dozens of full-time employees plus a generous contingent of volunteers. Ensuring the complex operation stays on course and within its $1.8 million operating budget is a tough job, but Ijams Executive Director Amber Parker has been doing it for six years now and has no desire to be doing anything else.
When Amber talks about Ijams she fairly bursts with giddy, infectious energy. This is a woman who has clearly found her place in the world, and even a brief walk along any of the center’s 21 trails makes one wonder if the land itself hasn’t responded in like fashion to her devotion.

Wildlife masterpieces mark an artistic autumnal fundraiser for the Tennessee Aquarium
CHATTANOOGA — While getting ready to tackle his next artistic masterpiece at the Tennessee Aquarium, Avior the red-ruffed lemur likes to take a few steps to center himself: languid naps in the sunshine, delicate nibbles of romaine lettuce, a resounding howl to focus his energy.
Only after these rituals are complete can this master of composition — a true “Lemur-nardo” da Vinci — begin putting paw and tail to canvas to create his next opus.
Avior’s latest triumph — made using non-toxic, animal-friendly tempura paint, naturally — is a 16-by-20-inch piece created in collaboration with his fellow lemurs and social media star Atlanta-based artist Andrea Nelson (TikTok video). Avior and Nelson’s masterwork is one of more than two dozen pieces of art made by aquarium animals now up for bid during the Tennessee Aquarium’s online fall fundraising auction. The auction will conclude at noon on Monday, Sept. 26.
Foreign freshwater jellyfish have been swimming among us since the 1930s

Freshwater jellyfish: Here one year, gone the next.
KNOXVILLE — Paddling along the still water of Mead’s Quarry Lake you notice the air bubbles created by your oars. They are all around your canoe near the surface.
It’s a hot early September afternoon and the nearly transparent bubbles seem to take on a life of their own. You slow to watch and yes, they undulate, rising and falling in the pristine water of the abandoned marble quarry.
Air bubbles do not undulate!
Taking a clear plastic cup, you lean over the gunwale and scoop up one of the penny-sized bubbles to get a closer look.
Tentacles? Air bubbles do not have tentacles. What you are looking at is a freshwater jellyfish and the heat of late summer is its mating season. It’s a blossom of jellyfish as hundreds gather together near the water’s surface. They are commonly known as peach blossom jellyfish.
Citizen scientists are taking stock in Smokies, and the inventory keeps increasing

Next demonstration on Thursday, Oct. 20
GATLINBURG — Great Smoky Mountains National Park is celebrating the success of a community science project led by nonprofit partner Discover Life in America (DLiA) called Smokies Most Wanted. The initiative encourages visitors to record life they find in the park through the iNaturalist nature app. DLiA and the park use these data points to map species range, track exotic species, and even discover new kinds of life in the park.
“iNaturalist usage in the Smokies has skyrocketed from just four users in 2011, to 3,800 in 2020, to now more than 7,100 users,” said Will Kuhn, DLIA’s director of science and research.
In August, the project reached a milestone, surpassing 100,000 records of insects, plants, fungi, and other Smokies life submitted through the app. Among them are 92 new species not previously seen in the park.
