Aubrey Funke, the Assistant Director of the Imaging and Histology Core Facility (IHCF), welcomed the iCREATE students to the IHCF to learn how to use an extremely powerful (and extremely expensive) microscope! The Scanning Electron Microscope (SEM) can magnify 1,000,000 times - which is 1,000 better than a light microscope, which is already 1,000 time better than our eyes!
The Imaging and Histology Core Facility provides imaging services to faculty, undergraduate and graduate students, along with industry partners. They provide services in light microscopy, electron microscopy, and histology (microscopy of tissues).
Graduate Student Alyssa Talbert creates scaffolds for wound healing with elastin, collagen and water in her graduate work. But here, she is illustrating how to collect and stain cheek samples for the students to view under the light microscope.
Alyssa and Aubrey then take the students to compare the digital light microscope images with the detail they can see with the SEM. Because electrons have a very small wavelength, much smaller than the wavelength of light, the resolution using the SEM is much greater than that of light microscopes.
Aubrey and Alyssa shared a variety of SEM images with the students, from insects (see past Ugly Bug Contest winners below), to fungi, Alyssa's scaffolds, and much more!
The students spent approximately 8 hours at the IHCF learning how to use the SEM. They took copious notes they then followed explicitly, with Aubrey observing them, and they were able to run the SEM themselves on their last day of the training!
Thank you to both Alyssa and Aubrey for all the time and patient effort they put into instructing the students on the SEM. We weren't surprised to learn that Aubrey won the "Outstanding Staff Member" for NAU's Biology Department at their award ceremony on Wednesday, May 2nd. Congratulations to Aubrey!
Colleen Hopkins, Telehealth Coordinator for North Country Health Care (NCHC) shared an interactive lesson on NCHC’s Telehealth program with the iCREATE class on March 15, 2018.
NCHC reaches across all of Northern Arizona, stretching 500 miles from Nevada to New Mexico, and has 23 Access Points for care across this vast region. The mission of NCHC is to provide accessible, affordable, comprehensive, quality primary healthcare in an atmosphere of respect, dignity, and cultural sensitivity. The health and well-being of patients and community alike are promoted through direct services, training/education, outreach, and advocacy.
The NCHC Telehealth program uses video conferencing technology to link providers and their patients, as well as educators and health care consumers, to a comprehensive continuum of care. Using this technology, they can reduce the isolation of providers and their patients within rural communities. They can also save a lot of time. For example, a patient can get immediate information and help for behavioral health, diabetes, nutrition advice and more, without a practitioner needing to make a 6-hour drive.
The students watched a video about Project ECHO (Extensions for Community Healthcare Outcomes) by Dr. Sanjeev Arora from the University of New Mexico. He shared this collaborative model of medical education and care management that empowers clinicians everywhere to provide better care to more people, right where they live. The students then practiced using the system to watch their own heart rate on the monitor (photo above) that a remote doctor or nurse would be able to observe and hear real-time. They also used another monitor to see their ear drum (photo below).
Colleen ended the field trip with a tour of the NCHC facilities. Students got to see many areas in the clinic and see the dedication of the entire community working at North Country Health Care. Thank you, Colleen!
Dr. Bret Pasch, Assistant Professor in the biology department at NAU, is partnering with one of Jillian Worssam’s 8th grade science classes at Sinagua Middle School through the “Scientists in the Classroom” program founded by Jillian.
Bret specializes in recording and analyzing mouse vocalizations and has brought his digital sound recorder into Jillian’s classroom so the students can learn first-hand about singing mice. These grasshopper mice have a relatively loud voice so other mice can hear them over the vast distances in the desert where they live.
Bret shared audio recordings of the mice, and then slowed them down so the sound was more apparent to those of us with ears that don’t hear at high frequencies any more! He also showed the students how they can measure both the frequency and duration of the sounds on the sonogram.
The students are making hypotheses about whether the male or the female mice will vocalize more frequently, and which will have a higher pitch, higher amplitude (loudness), and longer duration of the sounds. Bret will leave the mice (male on one side of the room and female on the other) for the next few months along with the digital recorders so students can capture their vocalizations. The mice are nocturnal and vocalize more at night, so the students will be able to access their sounds when they return to school each day.
Bret fed the mice while eager students looked on. He fed them their natural diet of bark scorpions, which are one of most venomous scorpions in Arizona. These mice have a mutation in their pain receptors so they don’t feel the sting as much as another species of mice would. They also like Pinacate bugs that lift their hind ends and spray as a defense strategy. The mice have a behavior where they stick the bugs abdomens in the ground so they don’t get sprayed and then they eat the heads first!
Thank you to Bret for participating in the Scientists in the Classroom program and also for elucidating information on singing mice through a Science on Tap presentation to the community! Flagstaff really appreciates your scientific outreach to both our schools and our community!
Note: You can also see and hear the mice at Bonnie Stevens’ Brain Food story on Bret Pasch here!
As stated on their website: The Ancient DNA Lab provides support for researchers working with ancient, historical, forensic, or other sensitive (low DNA quantity/quality) genetic samples. Established by the School of Forestry’s Carol Chambers and Faith Walker in 2016, the Ancient DNA Lab is physically isolated from other genetics labs on campus and adheres to rigorous quality control measures to prevent contamination, both of which are internationally recognized standards for the early stages of ancient DNA handling and processing.
The Ancient DNA Lab is sterilized (left) and ready to use in 2018.
The 2017 iCREATE class (right) was able to go into the lab between cleanings.
Some of the projects the lab has been involved with include a 10,000 year old bat, research using both extant (living) bats and bat guano, the 8,500 year old bison (below), and work with extant wombats in Australia.
Undergraduate Research Assistant Sam Hershauer presented some basic information on how DNA is extracted, amplified and analyzed in the aDNA Lab. Sam is working on collaborative research project on DNA from organisms in Alaskan lake sediments going back thousands of years. This collaborative project is with the Arctic Lakes Project headed by Dr's. Nick McKay and Darrell Kaufman in the School of Earth Sciences and Sustainability.
Thank you to Faith, Colin and Sam for sharing your hidden treasure with the iCREATE students!

Congratulations to San Francisco de Asís Catholic School 6th grade student Robert Zavala. Robert earned a 3rd place Bronze medal at the Arizona State Science and Engineering Fair. Robert qualified to compete at the state level by winning first place at his school competition with his project “How much Pure Aluminum is in the Average Soda Can?” Robert constructed a homemade foundry and reached temperatures of over 1200 degrees F to melt 30 aluminum cans. He separated the pure aluminum from the “dross” or non-aluminum material and determined how much aluminum is in the average soda can.
At the State Fair Robert competed in the 5th and 6th grade Engineering category with 47 other students from across Arizona. Robert was interviewed by four judges during a three and a half hour exhibition at the Phoenix Convention Center to earn his bronze medal.
In total, over 900 students and 700 projects were registered for the state fair. Only
students who place first at their school fair may compete at the Arizona State Science and Engineering Fair. Congratulations to Robert!

Every student enrolled in our CAVIAT programs has the opportunity to participate in a Career and Technical Student Organization (CTSO). These organizations provide scholarships, competitions, leadership opportunities and so much more that enriches the life and learning of our students.
Some of our students are traveling to the Arizona state competition hosted by the CTSO, HOSA - Future Health Professionals. HOSA is an international organization focused on developing character and technical skill competencies for members, to uplift current and future people in the health professions.
Our students are there to compete in a variety of subject matters. Madison Stump, of the Medical Professions program, is competing in the Behavioral Health event. Cylie John, also in the Medical Professions program, is taking the Medical Law and Ethics test. Dakota Palmer, of the Veterinary Assistant program, is doing the Veterinary Science skills test. Zachary Ashland and Elizabeth Strones, from the Bioscience program, are both taking part in the Medical Innovation event, and their classmate Antonia Green is taking the Biomedical Laboratory Sciences test.
To qualify for this week's state competition, students took an online test which covered a wide variety of topics from their program's curriculum. Only top scoring students are allowed to attend the state competition and earn the chance to move on to the international competition at the International Leadership Conference, which takes place at the end of June.
The state competition this year is taking place in Tucson, from April 2nd through April 4th. Let's cheer them all on to victory!
And not to be left out of the fun, this week our Fashion Design and Merchandising program is headed off to Los Angeles! They're going to visit the Fashion Institute of Design & Merchandising and the LA fashion district. They've been fundraising for this trip all year, and all the hard work has finally paid off.

On Saturday, March 10th, 2018, Open Space staff completed the first session of the 2018 Indigenous Youth STEM Academy. This year, we are partnering primarily with the Kinlani Bordertown Dormitory which consists of 9th-12th grade Native American students from various tribes. We had 9 students participate in our first session. The STEM focus area of this session was astronomy and included a site visit to Lowell Observatory. Our program began with a hike from Kinlani Dorm to Lowell Observatory via Observatory Mesa trail system. This gave us an opportunity to explain the significance of the relationships between Flagstaff Open Space and our neighboring properties.
Participants were given a private one hour tour of the Lowell campus followed by a 30 minute guest presentation from astronomer and researcher, Dr. Deidre Hunter, who is also co-founder of the Navajo-Hopi Astronomy Outreach Program. This program connects astronomers from Lowell to schools on the Hopi and Navajo reservations to partner in culturally-relevant astronomy-based curriculum. Dr. Hunter tailored her presentation to our specific group with a focus on the importance of minorities in STEM. She discussed her educational background and career path, gave information on her research, and described the Navajo-Hopi Outreach Program and how the program came about. The program session concluded with lunch provided for the students, transportation from Lowell back to the dorm provided by the Boys and Girls Club, and a gift card drawing for all participants. Students filled out questionnaires that aimed to gauge their interest in STEM careers, their interest in college, their favorite and least favorite parts of the program session, and why they think it is important for Native Americans to be in STEM careers fields.
Our next session will be a two part session taking place on March 26th and 31st with a STEM focus of Art and Graphic Design. Our guest presenter, Corey Begay, is a local Navajo STEM professional and artist who is the Lead Artist and Graphic Designer at the multicultural publishing company, Salinas Bookshelf, Inc. He will present to students on Monday night at Kinlani Dorm about his career path in STEM followed by a hands-on art activity. Part two of this session will take place on Saturday, March 31st which will consist of a visit to Picture Canyon Natural and Cultural Preserve. The students will be taken on an interpretive tour of the Preserve where we will focus on the importance of our interpretive signs to show the possibilities of turning interests in art and graphic design into a professional career. Corey Begay will be present during this tour to share his knowledge and experience about turning a passion for art into a career.
Thank you to Marcus Yazzie, Recreation Coordinator, and Vicki Anderson, STEM VISTA at Kinlani Bordertown Dormitory, for their assistance with this event! If you would like to sign up for the Flagstaff Open Space Newsletter, click here!
Eleven high school students in the CAVIAT iCREATE bioscience class publicly presented their unique solutions to the authentic problem of tracking and reporting influenza-like illnesses in Coconino County. The presentations were held on March 7th at NAU's Center for Science Teaching and Learning. The students are in the second semester of this college-level course that earns credits from both Coconino Community College plus from Coconino High School or Flagstaff High School. The class meets after school for 2.5 hours each day from Monday to Thursday to learn the CTE (career and technical education) bioscience standards through an epidemiologic lens and with rich community involvement. Community partners include Coconino County Public Health Services District, North Country HealthCare, Northern Arizona Area Health Education Center, Northern Arizona Healthcare and TGen North. The students also gained assistance from Corryn Smith in using GIS technology for their reports.
Instructors Dr. Aaron Tabor and Robert (Bobby) Woodruff co-teach the class at NAU. Both have extensive experience in research and education. They also include additional community partners for in-class presentations and field trips. Students have toured the Science and Health Building at NAU, the Center for Ecosystem Science and Society (ECOSS) laboratories, the Clinical and Pathology Laboratory at Flagstaff Medical Center, and more!
The students study disease-causing agents as then use the tools necessary to determine what microbes cause the illnesses. The class includes biosafety skills, microbiology techniques, DNA extraction, separation and analysis. Students take an end-of-year test to demonstrate their knowledge and skills.
Congratulations to all the students! And thank you to the community members that attended their presentations! NAU Provost and Vice President for Academic Affairs Dan Kain (Left), FUSD Assistant Superintendent for Curriculum and Instruction Mary K Walton (Center), and FUSD Superintendent Mike Penca (Right), all came to hear the student presentations and ask them questions about their unique solutions to this authentic community problem.

A Ribbon of Life for Flagstaff Students, Residents, and Visitors
Walking from City Hall north you will find yourself on the Flagstaff Urban Trail System (FUTS), seemingly headed towards the San Francisco Peaks. As you pass the Public Library, you’ll notice Wheeler Park to your right and a grassy, depression with a footbridge crossing to your right, the Rio de Flag.
An ephemeral stream, you will not see water in this grassy channel unless a monsoon hits in the summer or snow melts and flows downstream in the winter.
Keep wandering half a mile up the FUTS along the Rio de Flag and you will quickly arrive at Frances Short Pond. Filled naturally and sometimes supported with additional reclaimed water, the “duck pond” is one of the most visited sites along the Rio due to the recreation and wildlife viewing opportunities it provides.
The pond and the Rio flowing downstream from it provide a unique setting for Flagstaff students to learn about their environment. The Rio also gives students a chance to give back to their river through restoration and citizen science.
It is my goal as an AmeriCorps STEM VISTA member to connect Flagstaff students with the Rio de Flag. That is why I started the Adopt-the-Rio de Flag Stewardship program in my first VISTA term in 2016-2017. This program allowed me to connect with local teachers to share resources and provide introductory lessons on the Rio de Flag.
In fall 2017, freshman and sophomore biology students at Flagstaff High School began participation in the program. First, the students engaged in a classroom Introduction to the Rio, exploring different aspects of the Rio in small groups.
The following month, students collected data on the Rio de Flag, which was done in partnership with the Arizona Department of Environmental Quality’s citizen science program called Arizona Water Watch. All of the photos in this blog post are courteous of these students who worked hard to document their surroundings as part of the data collection protocol.
During the remainder of my position, I hope to expand these place-based learning opportunities to other Flagstaff students. To achieve this goal, I will host a teacher workshop in the spring that focuses on stewardship, citizen science, and the Rio de Flag. This will give teachers the tools they need to connect their students to the Rio de Flag as stewards of their local river.
In order for the Adopt-the-Rio program to continue into the future, I also conduct grant writing and partnership building as part of my AmeriCorps STEM VISTA position. These tasks require a watershed-wide focus and long-term visioning with guidance and support from local government, residents, businesses and nonprofits.
The Rio de Flag is Flagstaff’s river, and it is our collective duty to protect it for future generations. My AmeriCorps STEM VISTA position gives students the chance to take the lead in protecting and restoring the Rio through citizen science and stewardship.
If you’re unfamiliar with the Rio de Flag, we welcome you to watch our new short film, “Ribbon of Life.” Produced by one of our volunteers, Brittain Davis, this film is about those who visit and love the Rio de Flag.
