Dartmouth Previews National Science and Engineering Festival in the Upper Valley

The “Stellar Forensics” group demonstrates how to ‘dissect’ light during an early preview at the Christa McAuliffe Planetarium.

On Saturday, September 11, three teams of Dartmouth faculty and graduate students will lead three hands-on exhibits from 10:30 a.m. to 12:45 p.m. at the Montshire Museum of Science in Norwich, Vt., and from 1:30 to 3:30 p.m. at the Vermont Institute of Natural Science (VINS) in Quechee, Vt.

The faculty and graduate students represent the departments of physics and astronomy, engineering, earth sciences, and chemistry. The groups are teaming up with the Upper Valley science museums to host interactive “USA Science Festival Preview Day” exhibits in preparation for the inaugural USA Science & Engineering Festival located in Washington, D.C. on October 24 and 25.

Billed as the “Woodstock of Science,” the USA Science & Engineering Festival is a 16 day-long event to promote science, technology, engineering and math to the nation’s youth. The event culminates with the festival on the National Mall and is expected to attract thousands of attendees. The Montshire and VINS provide Dartmouth’s festival team with the opportunity to showcase the groups’ exhibits in a local setting.

Hosting the preview for Upper Valley youth is important to Dartmouth’s festival team. “Today’s students will enter a world of unprecedented challenges in energy, environment, health, security, and education,” says Solomon Diamond ’97, Thayer ’98, assistant professor of engineering and faculty leader of the exhibit “Biosignals! Synchronizing Rhythms in the Human Body.” “The creative problem solving and inspired leadership that is needed to stare down these challenges starts with the innocent curiosity of youth.”

 Ivan Aprahamian leads a demonstration of “DNA Misbehaving” during an early preview at the Christa McAuliffe Planetarium.

Dartmouth’s exhibits in both the Upper Valley and D.C. will engage people of all ages in the sciences through observing light from supernovae, evaluating melting polar ice caps, discussing DNA assembly, and investigating biological rhythms.

Danny Milisavljevic, a physics and astronomy graduate student, researches light from exploding stars (supernovae) and the evolution of supernovae explosions to gain insight on how the first supernova explosion occurred. Milisavljevic says, “Dartmouth is at the forefront of finding opportunities to disseminate the research in ways that can be appreciated by general audiences at local and national levels. I’m proud to be a part of this effort.” Milisavljevic is a member of the “Stellar Forensics” group led by faculty member Brian Chaboyer.

Nancy Serrell, director of outreach, and David Kotz, associate dean of the faculty for the sciences and professor of computer science, are organizing Dartmouth’s USA Science & Engineering Festival participation.

Biosignals! Synchronizing Rhythms in the Human Body

The rhythm of life is fundamental to the function of our heart, muscles, and brain. Outside our conscious awareness, our heartbeat, breathing and even our muscle contractions are coordinated not just with each other but with the environment around us. But what happens if we do become aware of our own rhythms? Can we change them at will, or coordinate them with someone else’s biological rhythms? Come see for yourself and learn what scientists are discovering about the brain’s function in synchronizing our biological rhythms.

DNA Misbehaving: Self-Assembly Gone Wrong

It happens naturally all the time—within each cell of our bodies, molecules assemble themselves into the forms we need for life.  But what is self-assembly and how does it work? Come see the self-assembly of patterns essential for the development of life! Did you know you have about 2 yards of DNA in EVERY one of your tiny cells? You can also see how DNA uses special types of organization to encode the information of life and to fit into your cells. What do you think happens when the DNA misbehaves and disobeys these rules of organization? Come find out!

Polar Detectives

Just as clues helped Sherlock Holmes solve murder mysteries, "fingerprints" hidden deep in glacier ice help today’s polar scientists decode climates of the past. What are they finding, and why is it important to you?  Try out your own detective skills by touching and analyzing an ice core from Greenland that originated as snow hundreds of years ago. Create a model glacier and watch it flow. Get the real scoop on abrupt climate change as you talk with a scientist who works at the South Pole!

Stellar Forensics

By observing light from the cosmos, Dartmouth scientists are reading clues from the past to help us understand the world we live in today. How were the elements that make up everything on Earth created? Are Earth-like planets common around other stars? Come join us on a scientific exploration into the origin of the building blocks of life.
