Physics Outreach Volunteers Visit Franklin School
Undergraduate volunteers from the Department of Physics took some of their favorite kid-friendly demonstrations to share with families at the annual Family Science Night at Franklin School, Corvallis, on January 25th. The demonstrations included exploding balloons in a vacuum chamber, the dielectric breakdown of air, target practice with a vortex cannon, rainbow effects with diffraction glasses and the department’s home made hover craft. Many thanks to volunteers, Zack Colbert, Lincoln Worley, Mirek Brandt, Garrett Jepson, Hanna Hansen, and Mattia Carbonaro.
Small currents hold big clues to understanding nanoscale diodes
The work of OSU physics graduate student Lee Aspitarte was featured as a Scientific Highlight on the American Institute of Physics website. Lee’s recent experiments in Ethan Minot’s lab provide new insights about nanoscale pn-junctions. Nanoscale pn-junctions are a promising technology for maximizing the efficiency of light-to-electricity conversion.
WIC Culture of Writing Award in Physics 2017
This year’s winner of the WIC Culture of Writing Award in Physics is Jeremy Meinke, for his thesis entitled, “Single-Molecule Analysis of a Novel Kinesin Motor Protein.” Jeremy worked under the direction of Prof. Weihong Qiu. He was with the Qiu research group for two years and in 2016, he received URISC and SURE awards to support his work. Jeremy says of the OSU Physics Department, “I enjoyed the range of physics topics the upper division classes offered, which kept me constantly thinking about new concepts. Overall, it was a great place for me to study physics. I truly benefited from the research experience.”
Atul Chhotray is Awarded the 2017 OSU Physics Graduate Research Award
Atul Chhotray was awarded the 2017 Physics Department Graduate Research Award.
A native of India, Atul joined OSU in 2014 as a transfer student from North Carolina State University.
Atul has since performed his research in the computational astrophysics group of Dr. Davide Lazzati.
Waiting for Starlight
Family Science Night at Timber Ridge
Physics graduate student Carly Fengel shows a Timber Ridge Elementary School student the beautiful spectral lines of hydrogen, helium, argon and neon lamps. When viewed through diffraction grating glasses, the various wavelengths of light are split apart, revealing a unique signature for each gas. “So we could tell what stars are made of!” remarked the student.
Family Science Nights have been a yearly staple in Corvallis schools for more than a decade, but May 16 was only the second one for Timber Ridge School, a combined middle and elementary school serving a rural area on the northern edge of Albany. About 200 students of all ages attended the event, with middle-school students acting as guides and selling snacks as a fundraiser.
In addition to volunteers from the physics department, OSU was represented by other departments, including the College of Veterinary Medicine, the College of Earth, Ocean, and Atmospheric Sciences, and the School of Nuclear Science and Engineering. Non-departmental groups also showed up, such as the Dairy Club, Geology Club, and Fisheries and Wildlife Club. For the first time, nursing students from Linn-Benton Community College made an appearance, rounding out the science offerings with tables focusing on exercise, vital signs, CPR, and hand-washing.
Other physics demos included classics like levitating ping-pong balls with a hair dryer and the ever-popular hovercraft. As usual, the line for the hovercraft rarely dropped below a dozen students, continuing to draw a crowd to the end of the hall throughout the evening. Many were eager to learn how the hovercraft worked and several times kids remarked: “I want to make one!”
(Prof. Ethan Minot explains the design of the hovercraft)
As the last Family Science Night of the school year, this event ended the semester on a high note, with several new groups and a new physics demonstration. Both volunteers and families will be looking forward to next year’s school outreach events.
A big thank you to the physics student volunteers Evan Peters, Garrett Jepson, and Carly Fengel.

Interactive Science at Mi Familia Weekend
Physics joined the Mi Familia Weekend for a hands-on showcase of science. The Mi Familia Weekend is an annual 2-day event that is designed to connect diverse and underrepresented families with their college students and the OSU community. The interactive science and engineering sessions incorporated demonstrations and activities from Physics, Chemistry, Microbiology, Engineering, and more. Dr. KC Walsh and Learning Assistants from the introductory physics course brought a host of fun physics toys to engage the young K-12 participants. Demonstrations from the physics group included a magnetic levitation track, hovercraft, Tesla coil, liquid nitrogen freezing, and much more.
Discovery Days
Story by Monica Bennett
Physics was one of nearly a dozen departments and groups that came together to create the attention-grabbing, educational smorgasbord of OSU Discovery Days.
The event is coordinated by Prof. Margaret Haak of the Department of Chemistry, who took over in 2003 and expanded the program from its predecessor, “Museum Days”. Prof. Haak estimates that about 1,800 children flooded into LaSells over the course of two days, enjoying science demonstrations and trivia games from science departments and other groups, including the sorority Sigma Delta Omega, the Physics 111 course, and local business Brad’s World Reptiles.
The Department of Physics claimed the majority of one of the rooms in the LaSells center, mostly for the sake of the rotating chair that sat in the center of the room. Here students lined up to take a spin, using hand weights to test how concentrating their center of mass increased their speed of rotation, while extending their hands slowed it.
Having discovered some principles of angular momentum, the dizzy students then staggered over to the tables, which contained more physics demonstrations. The demos, all hands-on to some extent, included ping-pong balls supported by a hair dryer, as well as a large tank of water in which students tested their predictions on the relative buoyancy of regular vs. diet soda and cucumbers vs. grapes. A particular favorite was the table of vacuum experiments, featuring not only a chamber that demonstrated the effect of vacuum on balloons and bubble wrap, but also a steel ball that students tried to pull open, discovering the pressure difference when the air inside was evacuated by the vacuum pump.
Physics demos were on display from other groups as well—a contingent from Physics 111 (taught by Prof. Emily van Zee) showed off their skills as future teachers with an array of optics demonstrations, showing students how refraction changes the apparent location of an object submerged in water and how reflectivity varies in different materials. Elsewhere, students watched a Geiger counter detecting uranium in old Fiestaware and observed changes in surface tension with soap and water, being introduced to a variety of physics concepts in addition to the department’s own offerings.
Prof. Haak’s hope for Discovery Days is for students to feel involved, seeing that “science is something you do, not just something you read about.” She believes that major outreach events are valuable to the volunteers as well as the visitors, stressing the importance of communicating science well and encouraging hands-on exploration. With these guiding values and contributions from the fields of physics, biochemistry, botany, herpetology, and more, the spring 2017 Discovery Days were a delight for students and scientists alike.
A big thank you to the physics students who volunteered their time: Ikaika McKeague-McFadden, Willis Rogers, Kelby Petersonm, Zach Colbert, Abe Teklu, Isaac Hodges, Tymothy Mangan, Ian Goode, Ryan Bailey Crandell, Katy Chase, James Haggerty, Carly Fengel, David Rivella, and Nikita Rozanov.
Eclipse video from the Corvallis-Benton Public Library explains it all
Physics graduate student Tyler Parsotan explains the science of a Solar Eclipse in this How-To video. Tyler is President of the Oregon State Astronomy Club and is working with schools and libraries on information about the Eclipse on August 21, 2017. Tyler’s explanation is about 2:00 in the video.
