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.

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.

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.

On Saturday, March 4th, the Physics Department was part of the annual “Discovering the Scientist Within” event at OSU. Twenty-three middle school girls from all over Oregon visited the department and learned about physics by playing with some of our coolest physics toys.

The girls drew “physicists doing physics” on the wall-mounted touch screens in our hi-tech studio classroom. The girls played with our superconducting train, centrifuge chair, precessing bicycle wheel, standing wave strobe setup and tabletop hovercrafts. They used OSU diffraction glasses to look at atomic emission spectra. They zoomed down the halls of Weniger on our leaf-blower hovercraft. We turned out the lights and did some “light painting”. We finished the day with homemade liquid nitrogen ice cream.

Shane Larson, BS 91, has won the Vth Fermilab Physics Slam – a public contest in which scientists are given 10 minutes on stage to explain what the heck they do to over 1000 people in a sold out auditorium.

http://www.chicagotribune.com/suburbs/aurora-beacon-news/news/ct-abn-physics-slam-st-1202-20161201-story.html  has a Chicago Tribune article about the contest.

Shane works  at the Adler Planetarium and teaches at Northwestern University.  He gave a talk here in 2016 on the LIGO gravitational wave discovery.

 

At the most recent Astronomy Open House, on February 17th, many tried to reach for the… planets?

The newly formed OSU Astronomy Club and the Department of Physics hosted the most recent Open House with invited activities by the Corvallis Public Library and the Corvallis Arts Center. The event also featured Tom Carrico of the local amateur astronomer club: Heart of the Valley Astronomers who talked about how to view an eclipse safely.

At the event, parents, college students, and children alike, learned about how telescopes work, how astronomers identify what stars are made of, what causes the seasons, and the different types of shadows formed by an eclipse! Once each person completed their activity sheet, they were able to get a free commemorative eclipse poster about the upcoming Total Solar Eclipse in August.

Everyone seemed to love the event, and the OSU Astronomy Club is working to make the event even better than it already is, especially with anticipation growing for clear weather for the next Open House! So be sure to keep an eye on facebook.com/osuastronights to hear about the next exciting Astronomy open House! We hope to see you there!

 

 

Elementary school students at Franklin School, Corvallis, enjoyed the wonders of riding a frictionless craft across the school gym on Thursday night. They also learned how to make their own hovercraft using an old cd, and checked out other “wow” physics demos. Many thanks to the student volunteers from the Department of Physics who gave over 150 kids a super fun experience with physics. More school events are coming up soon.

The Spectrometer has been operating from the Oort cloud for the past few months, hence some delays in the signal reaching you.

A big event Spring quarter was Janet Tate’s masterful Gilfillan Lecture, “It’s a Materials World” on May 9th.

If you ever wanted to know what goes on in her lab, this is the lecture to watch.
