Focus Speaker Feature – Karis McFarlane
by Lisa Hegdahl
Karis McFarlane is an environmental scientist who has been using radiocarbons to study and better understand the carbon cycle since 1999. By studying Earth’s carbon cycle—the exchange of carbon between the planet’s land, atmosphere, and oceans—scientists are trying to understand the role played by huge tropical rainforests such as the Amazon River basin. In particular, they want to determine how long an ecosystem stores atmospheric carbon dioxide in its plants, soils, and rivers. At the 2012 CSTA Conference, Karis McFarlane will discuss the ways radiocarbon is used to study carbon cycling in ecosystems, and why it’s unique and important for climate change. She will focus on the importance of understanding how much, and for how long, carbon is sequestered in soil, as well as the role it plays in the carbon cycle. Environmental science educators and other conference attendees will find this lecture informative and thought provoking.
Karis grew up in St. Louis, Missouri and spent a lot of time in the woods canoeing and camping with her family. She received her Bachelor’s degree in Environmental Science from DePaul University in Chicago. As an undergraduate student, she worked as a research assistant studying restored prairie, oak savanna, and woodlands. Her interest in forest ecology led her to Syracuse, New York where she earned her Master’s degree in Forest and Natural Resources Management at the SUNY College of Environmental Science and Forestry. Later, Karis moved to the West Coast to pursue her Ph.D. in Forest Engineering with a minor in Soil Science. For her dissertation, she investigated the effects of forest management on soil organic matter, which is important for carbon sequestration and sustainable forestry. She was awarded her Ph.D. in 2007 and was hired by Lawrence Livermore National Laboratory as a post-doctoral researcher. She currently works at LLNL’s Center for Accelerator Mass Spectrometry where she and other scientists measure rare isotopes like radiocarbon (14C) for lots of different kinds of research. In general, though, Karis uses radiocarbon and other measurements to study terrestrial carbon cycling, particularly in soils and natural ecosystems. Her work is contributing to the development of more realistic carbon cycle models that will improve our ability to model changes in climate and anticipate the effects of climate change in the future. When she isn’t working, Karis enjoys running, bicycling, and yoga and spending time with her husband and their two big dogs.

Since the public reviews of the Next Generation Science Standards have come to a close, like many primary teachers, I’ve been wondering what science will look like in kindergarten, first, and second grade classrooms. Learn More…
“SOL Grotto, 2012. 1368 glass tubes, paint. Fabrication: Matarozzi Pelsinger, Rael San Fratello Architects. SOL Grotto is a contemporary take on a grotto or Throeau’s cabin – a spartan retreat that is a space of solitude and close to nature – where one is presented with a mediated experience of water, coolness and light. The SOL Grotto also explores Solyndra’s role as a company S#@t Out of Luck. 1,368 of the 24 million high tech glass tubes destined to be destroyed as a casualty of their bankruptcy, are used in the installation. The tube’s original role as a light concentrating element is extended to transmit cool air into the space via the Venturi effect, to amplify sounds from the adjacent waterfall via the vibrations of the tubes cantilevering over the creek, and to create distorted views of the garden. The form of the electric blue array evokes Plato’s Allegory of the Cave where shadows, light and sounds can call reality into question.”

Congratulations to CSTA member and STEM Educator, Katherine Schenkelberg, of West High School, in Torrance, CA! Katherine was recently awarded one of the 2013 Vernier/NSTA Technology Awards. An appointed panel of experts selected her for her innovative use of data-collection technology. “The use of data-collection technology in the classroom helps foster students’ interest in STEM education and provides them with engaging, hands-on opportunities for scientific investigation,” said David Vernier, co-founder of Vernier and a former physics teacher. “For ten years Vernier and NSTA have recognized innovative STEM educators through this award and this year’s winners are no exception – their projects and programs truly utilize the power of data-collection technology as part of the teaching and learning process.” Learn More…
