Students Share Quantitative Analysis Research at Poster Session

On Dec. 9, more than 100 students participated in the Quantitative Analysis Center Research Poster Session in Beckham Hall. The poster session served as the students’ QAC 201 final exam. The event provides students with the opportunity to share the fruits of their work with others. Several Wesleyan faculty and alumni evaluated the students’ poster presentations.

Funded by the National Science Foundation, the QAC 201 course allows students to ask and answer questions about which they feel passionately. Students generate hypotheses based on existing data; conduct a literature review and evaluate the content of empirical research; prepare data for analysis; select and conduct descriptive and inferential statistical analyses; and present research findings to expert and novice audiences. By providing opportunities to learn one of four major statistical analysis software packages, and translate across them, this course aims to empower students to manage, analyze and interpret large data sets from a range of different disciplines.

Local Children Learn about Physics from Wesleyan Faculty, Students

Christina Othon, assistant professor of physics, assistant professor of integrative sciences, met with students enrolled in the Green Street Teaching and Learning Center‘s Discovery AfterSchool Program on Dec. 1. Othon and Wesleyan students Danielle Levinson ’19, Alexis Braunrot ’18 and and graduate student Stefan Kramel taught the AfterSchool attendees about physics through hands-on activities.

GSTLC s a community-based studio that develops, applies, and disseminates best practices in experiential teaching and learning which enhance Wesleyan and the greater community. The Discovery AfterSchool Programs offers a range of classes in the arts, sciences and math for children in Grades 1- 5.

The objective for the day was to investigate the properties of matter, to review the states of matter, and to discuss some of the ways we can change the properties of matter. Othon’s expertise is in soft matter, and therefore the group focused on fluids, gels and plastic deformation. After reviewing how to define the properties of a liquid, students were asked about how they would characterize some unusual materials like peanut butter or Jell-O.

“Of course these are materials which hold their shape, similar to a solid, but deform under stress or strain like a fluid. We therefore determined that the categories of liquid, gas and solid are not rigid categories, but that some materials have properties of both,” Othon said. “We then conducted some experiments on viscosity where students made predictions about which fluids would flow most quickly down an incline plane. The fluids were water, oil, chocolate sauce, honey and ketchup. The students observed that the ketchup behaved differently than all of the other fluids, and that the clumping of the ketchup dramatically impacted how fast it flowed.”

After investigating viscosity, the group discussed how to change the properties of materials. The students recognized that through temperature they could change water to a solid.

To demonstrate the change in structural properties, Othon and the students decided to make bouncy balls through chemical crosslinking. The students took two fluid solutions (glue and starch, and a salt solution in water), and mixed them to make their own bouncy balls.

“This is a messy project, but is highly engaging and the students greatly enjoyed it,” Othon said. “We always have a lot of fun working with the children at Green Street. We hope that this experience helps makes studying science exciting, and that they realize they can make observations of everyday objects and phenomena in their home.”

5 Classes Perform at Worlds of Dance Concert

The Worlds of Dance Concert, held Dec. 4 at Crowell Concert Hall, featured the works of five different dance courses in their semester-end culminating performance. Beginning and intermediate dance students performed works in various styles including Bharata Natyam (South Indian classical dance). The classes were taught by Pedro Alejandro, associate professor of dance; Susan Lourie, adjunct professor of dance; Hari Krishnan, associate professor of dance; and Katja Kolcio, associate professor of dance.

More than 90 Students Perform in West African Drumming and Dance Concert

The Center for the Arts hosted a West African Drumming and Dance Concert Dec. 2 at Crowell Concert Hall. The performance featured master drummer Emmanuel Attah Poku; choreographer and artist-in-residence Iddi Saaka; and more than 90 Wesleyan students. In addition, the Kiniwe African Dance Ensemble from Tufts University also performed at the concert. The event showcased the vibrancy of West African cultures through their music and dance forms.

Redfield Speaks to Wesleyan Staff about Discovering Exoplanets

eve_astro_2016-1031005342

On Oct. 31, Seth Redfield, associate professor of astronomy, spoke on “Blue Skies on Distant Worlds” during a special luncheon for staff in Daniel Family Commons. Redfield, whose research interests focus on exoplanets and their atmospheres, explained how astronomers can detect and measure planets outside of our solar system. In the same way Earth orbits around the sun, an exoplanet will circle around a star. For some planetary systems, from Earth, astronomers can view the the exoplanet passing directly in front of its host star once per orbit.

Wesleyan’s Navaratri Festival Celebrates 40th Anniversary

Navaratri, one of India’s major festival celebrations, is a time to see family and friends, enjoy music and dance, and seek blessings for new endeavors. Wesleyan’s 40th annual festival, held Oct. 28-Oct. 30, celebrated traditional Indian music and dance.

The Navaratri Festival is presented by the Center for the Arts and the Music Department, with leadership support from the Madhu Reddy Endowed Fund for Indian Music and Dance at Wesleyan University, and additional support from the Jon B. Higgins Memorial Fund, the Raga Club of Connecticut, Haveli Indian Restaurant, and individual patrons.

Neighborhood Preschoolers Trick-or-Treat on Wesleyan’s Campus

On Oct. 31, Wesleyan’s Neighborhood Preschool participated in the annual NPS Halloween Parade. The children, accompanied by their families and care-takers, stopped at Olin Library, South College and North College to trick-or-treat, sing songs and show off their costumes. Many trick-or-treaters are the children of Wesleyan faculty and staff. Several staff from University Communications dressed up and offered candy to the parade participants. (Photos by Olivia Drake)
