Kids Have a Ball With Math and Biology

Kelly Sturner, NIMBioS Education & Outreach Coordinator, prepares to throw a beach ball Earth into the hands of Andersonville Elementary School Students.

Catch! Kelly Sturner, NIMBioS Education & Outreach Coordinator, prepares to throw an inflatable globe into the hands of Andersonville Elementary School students.

How can you use an Earth beach ball to estimate the area of forest on our planet’s surface? Andersonville Elementary School students figured this out and more at the interface of math and biology on their visit last week to the University of Tennessee.

One hundred and fifty 4th-6th grade students filled the auditorium at the university’s library, excited about the fun-filled day ahead of them meeting scientists and eating pizza. , NIMBioS Associate Director for Education & Outreach Suzanne Lenhart began the NIMBioS math biology session by talking about her work studying various diseases, including whether cats make people crazy (or rather, the effects of toxoplasmosis gondii on humans). Then, NIMBioS Education & Outreach Coordinator Kelly Sturner talked about her work as a soil ecologist and how she used math to study ecosystems such as forests.

The forest surface area on the inflatable globe was estimated using probability and tossing two identical balls around the auditorium, an idea modified from the environmental education curriculum designers at Project Learning Tree. The rest of the forest-math activities were modified from the NIMBioS education module Measuring a Forest.

Children reach for the Earth ball as it flies through the air. When they catch it, if their right index finger falls on green (forest), Sturner records it as well as the total number of tosses.

Gresham Middle Students Visit NIMBioS

A group of Gresham students, teachers and chaperones posed for the camera -- a Matlab edge detection software has transformed this image.

Gresham Middle School students, teachers and chaperones visit NIMBioS. A Matlab edge detection code transformed this image to give it a cartoon-like quality.

Local middle school students took their learning beyond the bounds of their classroom on a visit to NIMBioS last week. Fifty students from Gresham Middle School‘s Beta Club, along with teachers and parent chaperones, visited the institute and participated in hands-on activities exploring the connections between math and biology.

In one activity, designed and presented by NIMBioS High Performance Computing Specialist Eric Carr, students learned how computer code can help analyze images for biological applications. For the image lab, students explored how one could use the software to figure out the basal area of leaves. The students changed parameters for the program in Matlab to improve detection and imported images of leaves taken with webcams.

In a second activity, NIMBioS Associate Director for Education & Outreach Suzanne Lenhart explored with students the properties of platonic solids and how they relate to the structure of viruses. Students built solids from plastic triangles and made their own origami solids to take home.

Postdoctoral fellows Ryan Martin and Jeremy Beaulieu both helped with the activities.

Students finished out their visit to the University of Tennessee with a trip to CURENT, an engineering research center on campus, where they toured engineering labs. TNSCORE, another engineering research center on campus, was also involved in the visit and helped the students build small solar-powered cars.

In light of the success of the Discover Birds program among Tennessee elementary schools, the Tennessee Ornithological Society (TOS) voted at their annual meeting in Knoxville last weekend to order a second printing of the popular Discover Birds activity book.

The program appears to be meeting its primary goals of getting elementary school-aged children excited about birds and science. “The excitement and enthusiasm you see from the kids is a real thrill,” said Chris Welsh, NIMBioS deputy director and Discover Birds volunteer.

Welsh recently visited two local elementary schools with the program. At Sevierville Primary in April, 215 second grade students viewed a slide show about birds and examined feathers, owl pellets and other bird-related objects. Welsh joined other volunteers to lead students on bird walks on the school grounds where students spotted an American Robin sitting on a nest and Tree Swallows visiting nest boxes, as well as many other birds. More details and photos about the school visit are available at the Tennessee Ornithological Society Discover Birds blog.

Nearly all 1,000 activity books from the first printing have now been distributed with most having been donated to classrooms and teachers. NIMBioS contributed math-bird activities to the 36-page activity book. The math-related activities developed by NIMBioS for Discover Birds, along with illustrations by Vickie Henderson, are freely available for download here. For more information about how to obtain the Discover Birds activity book or to request a visit at your school, contact the Knoxville Chapter of the Ornithological Society.

Meet Education & Outreach Intern Kelsey Bratton

Kelsey Bratton, NIMBioS Education & Outreach Intern

Kelsey Bratton, NIMBioS Education & Outreach Intern

NIMBioS is pleased to introduce Kelsey Bratton, our education & outreach intern who began her work here in January. A junior in mathematics at the University of Tennessee-Knoxville, Bratton is enrolled in the VolsTeach program, which enables students to graduate with teaching licensure. She recently accepted a continuation of her position for the summer and fall semesters. In the following interview, learn more about what inspires Bratton, her future plans to teach mathematics, and her work at NIMBioS.

Why did you decide to participate in the VolsTeach program?

At first I was apprehensive about being in the VolsTeach Program. I couldn’t decide if I wanted to be a high school math teacher or an elementary school teacher. I have a passion for both. At my freshman orientation, I met Jada, the VolsTeach recruiter/coach. She encouraged me to consider VolsTeach. I like the idea of being able to graduate in four years with a math degree and a teaching license, but I still was not certain that I didn’t want to teach elementary school. After my freshman year, I decided that I did want to teach high schoolers, so I quickly got myself enrolled in the Step 1 class for VolsTeach. That was the perfect thing for me. VolsTeach has provided and will continue to provide opportunities that are ideal for a teacher-to-be. Everyone is friendly and helpful. It is a great program to be a part of!

What have you been learning so far at NIMBioS?

Since I have been at NIMBioS, I have primarily been working with Biology in a Box materials. I have been looking through the exercises and activities of each unit, and analyzing what math topics are addressed. Then I take those math topics and figure out what Common Core State Math Standards (for Tennessee) apply to each grade level. This way, when teachers use the Biology in a Box program, they have easy access to the Tennessee Common Core Math Standards that apply to each activity. I really enjoy being a member of the the NIMBioS team! Everyone here is helpful and kind. There are great things going on here, and I am thrilled to be a part of all of it!

What drew you to the field of education?

I have always wanted to be a teacher. Like I mentioned before, I wanted to teach elementary school. That was all I ever thought about doing. I do think that I would be a great elementary school teacher; however, I truly feel that I made the right choice in choosing high school math. I like the idea of helping teenagers learn difficult math skills and watching their knowledge in the subject expand. In the summer of 2012, I was an assistant at an algebra camp for incoming high school freshman who needed extra help to be able to be enrolled in algebra 1 that fall. It was an amazing experience that I will never forget. It was also a wonder learning experience for me. Those students were thirsting for someone to believe in them. When I become a teacher, I want to encourage students to pursue a higher education and let them know that they can do anything they put their mind to!

What are your current plans for after graduation?

After I graduate, I plan on becoming a teacher. I can hardly wait to have my own classroom and watch students become brighter, one math problem at a time. I think I would be perfectly happy returning to my hometown to teach if they’ll have me, but I will be happy anywhere.

Do you have anyone who inspired you to pursue education, or who has
inspired you in general?

All my life I have wanted to be a teacher. I believe it was because my mother is a third grade teacher, so the occupation always appealed to me. She always let me dream about being a teacher even though it seemed like everyone around me told me not to because of the pressures and the stress of it all. I appreciate her not discouraging me. Also, when I was in high school, I had a math teacher who inspired me in so many ways. Her name is Pattye Post. I never hated math because it always came easy to me, but her classes challenged me. She somehow, without meaning to, made her class fun. I only hope that someday I will be able to be as great as she is.

NIMBioS Spring Hikes: Phacelias and Salamanders in the Mud

NIMBioS at Porter's Creek, Great Smoky Mountains National Park

NIMBioS at Porter’s Creek, Great Smoky Mountains National Park

NIMBioS Fearless Leaders Chris Welsh and Lou Gross test the waters. It’s cold!

NIMBioS not only likes to study nature, we also like to experience it. NIMBioS colleagues, friends and their families enjoyed springtime hikes to Porters Creek and White Oak Sinks in March. The full display of wildflowers had not yet begun, but some white-fringed phacelia were starting to bloom on the Porter’s Creek hike. The hike to White Oak Sinks via Schoolhouse Gap trail was a muddy slog but good for spotting salamanders, thanks to the expert eye of NIMBioS postdoctoral fellow Julia Earl. Also spotted was a bat flying out of the caves at the Sinks. If you missed these, join us next time on the trail. Full set of photos on the NIMBioS Flickr page.

Julia teaches Hannah how to find salamanders.

Carlos Castillo-Chavez Appointed to President’s Committee on the National Medal of Science

Carlos Castillo Chavez

Carlos Castillo-Chavez

Congratulations to past NIMBioS Advisory Board Member Carlos Castillo-Chavez who has been appointed to President Obama’s 2013 Committee on the National Medal of Science.

Castillo-Chavez will be part of a committee of 12 engineers and scientists appointed by the president to evaluate nominees for the award. “I am grateful that these impressive individuals have chosen to dedicate their talents to serving the American people at this important time for our country.  I look forward to working with them in the months and years ahead,” said Obama in a White House press release today.

The National Medal of Science was established by the 86th Congress in 1959 as a Presidential Award to be given to individuals “deserving of special recognition by reason of their outstanding contributions to knowledge in the physical, biological, mathematical, or engineering sciences.” In 1980, Congress expanded this recognition to include the social and behavioral sciences. Since its establishment, the National Medal of Science has been awarded to 468 distinguished scientists and engineers whose careers spanned decades of research and development.

Castillo-Chavez, a Regents and a Joaquin Bustoz Jr. Professor of Mathematical Biology at Arizona State University, served on NIMBioS’ Board of Advisors from 2009 to 2011. He was also a co-organizer of the NIMBioS Working Group on Synthesizing and Predicting Infectious Disease (SPIDER). President Obama first appointed him to the President’s Committee on the National Medal of Science in 2010.

Women Researchers Share Their Stories with Aspiring Girls

IMG_2346_cropped

(From L to R): Maud Lelu, Julia Earl, A. Michelle Lawing, and Alison Buchan

With less than 25 percent of STEM (science, technology, engineering, and math) jobs in the United States currently held by women, women researchers and faculty from NIMBioS hoped to change that sobering statistic and inspire young girls from the L&N STEM Academy at the first ever STEM Breakfast held there on Wednesday.

NIMBioS postdoctoral fellows Julia Earl, Anna Michelle Lawing, and Maud Lelu, along with NIMBioS Associate Director for Graduate Education Alison Buchan, were among the 48 local women in STEM careers who were invited to shared their science stories and career advice with the high school girls. After breakfast, the high schoolers rotated among tables to conduct “speed interviewing” of the STEM professionals, who started with 90-second elevator talks about themselves and their careers. Then, the girls asked questions and engaged in conversations to network with the women.

The event, which was attended by about 50 female students at the STEM Academy, was designed to “start the awareness of what’s out there” for STEM careers, said organizer Mark Smith, Dean of STEM at the high school.

A 2011 U.S. Commerce Department report said that American companies urgently need professionals trained in science, technology, engineering and mathematics (STEM) fields, but there are not enough workers with the necessary skills and too few Americans earn post-secondary STEM credentials. And although women fill close to half of all jobs in the U.S. economy, they hold less than 25 percent of STEM jobs.

Not only is there a dearth of women in STEM jobs, more than half — 52 percent — leave when they hit the “mid-level” point in their careers, more than double the quit rate for men, according to a 2008 Center for Work-Life Policy study. The researchers cite factors that they call “antigens” that repel women, including hostile macho cultures, isolation, lack of mentors, poor work-life balance, and financial as the reasons. The ever-present income gap doesn’t help: In 2008, women in tech fields earned an average salary of $70,370.21. Over the same time period, men’s salaries averaged $80,357.

“I really wanted the high school girls to see that there are women out there doing all kinds of math and science for their jobs and that we are really excited and passionate about our work,” said Earl in explaining why she participated in the event. “The media often portrays science in a very narrow way.  It was great to see so many women working in many different disciplines and at the interfaces between those disciplines sharing what they do with high school students.”

Earl echoed what other women in STEM fields are saying — there is a noticeable lack of mentors, especially role models who have successfully navigated their careers while raising children. “I’ve never seen a woman with small children obtain tenure at a research university, a challenge I will be undertaking in just a few years. I think it’s hard to be sure you can accomplish something without having seen at least one person go through the same type of challenge,” she said.

The L&N STEM Academy, located in the restored historic L&N train station and depot in downtown Knoxville, is a public magnet school that opened in 2011. High school students from throughout Knox County are eligible to enter a lottery to attend. STEM permeates the school’s curriculum, even into English classes where students read and discuss Mary Shelley’s Frankenstein and Ray Bradbury’s Fahrenheit 451.

Kids Discover Birds with Math

DiscoverBirdsCover5_2 copyjpgTwo fun math activities for kids from the exciting world of birds are now available to download from our website. Both activities were designed at NIMBioS and recently published in Discover Birds, a 36-page activity book with fun facts about our feathered friends for elementary school-aged children.

NIMBioS Deputy Director Chris Welsh  and NIMBioS Education & Outreach Coordinator Kelly Sturner worked together on the project. Welsh is a past president of the Knoxville Chapter of the Tennessee Ornithological Society (KTOS) and studied forest-bird habitats for his PhD. Sturner also enjoys bird watching as a hobby.

One activity titled “Changing Populations” features real data from the North American Breeding Bird Surveys, where students explore how populations of Eastern Bluebird, Northern Bobwhite, and Wild Turkey have changed in Tennessee over time. The other activity, “Bird Champions,” is a simple math puzzle where kids solve arithmetic to break a code to learn about the fastest, smallest, largest, and tallest North American birds as well as the migrant with the greatest annual mileage in the world.

The book is a project of the Discover Birds program sponsored by the Tennessee Ornithological Society. Written and illustrated by artist Vickie Henderson, the book also contains other activities contributed by local naturalists and educators as well as organizations, such as the Great Smoky Mountains Institute at Tremont.

The book is available for purchase for a limited time at Henderson’s website. Most of the books have already been donated to classrooms and educators. Currently, only 170 of the 1,000 copies of the first printing are left.  A second printing of the book may be considered by the society in the April.
