Scientific Discovery

Toll Science Center

Welcome

Home to the John S. Toll Science Center, the Decker Laboratory Center, and Dunning Hall, the Toll Science Center complex is the heart of scientific research and discovery on campus. 

The science facility is named for College President John S. Toll, a noted physicist who served the institution from 1995 until 2005. The John S. Toll Science Center is a 45,000 square foot, state-of-the-art classroom, office, and laboratory complex. The facility houses chemistry and biology labs, a 94-seat lecture hall, an environmental classroom, two seminar rooms, a penthouse greenhouse, and a dramatic three-story glass atrium. The atrium connects to the newly renovated Dunning Hall, and the Alonzo G. Decker Jr. Laboratory Center.

 

Upcoming Events

November 4th, 2014

  • Image preview 6:00pm: Mike Vlahovich, Coastal Heritage Alliance (tentative date)
    Mike Vlahovich is the founding director of the Coastal Heritage Alliance. He is a master boat builder and restorer and is most interested in how restoring these boats is a means for restoring and preserving the watermen culture.

    Antidepressants and pharmaceuticals have been found in the environment as they are released in the effluent from wastewater treatment plants, which are not designed to remove such compounds from the water. This summer, Dr. Martin Connaughton and summer research student Kathy Thornton ‘13 are focusing on fluoxetine (Prozac) and its impact on the startle response in Zebrafish. Stimuli that are perceived as dangerous, in our case an acoustic/vibrational stimulus, can elicit a startle response from fish, aiding in the fish’s survival. Fluoxetine is a selective serotonin reuptake inhibitor (SSRI), which increases the concentration of serotonin in the blood, producing a “lighter” mood. It is hypothesized that under exposure to fluoxetine, the startle response will differ in swimming velocity and severity. Any decrease in responsiveness to a startle stimulus in response to fluoxetine would suggest that this compound, found in the environment, might decrease the likelihood of a fish surviving an attack by a predator.

    “Ahhhh, Strontium!”Pyrotechnics expert John Conking ‘65, an adjunct professor of chemistry, offered a talk on the Chemistry of Fireworks Saturday afternoon. Professor Conkling explained the chemical compounds and methods used to produce the various colors and special effects of fireworks displays.Conkling and Chris Mocella ‘01, a chemist with US Customs & Border Protection, collaborated on the second edition of Conkling’s book, The Chemistry of Fireworks, published in January 2011. The lecture was part of the College’s celebration of the 2011 International Year of Chemistry.

    In an illustrated talk, historian Peter H. Wood used Winslow Homer’s 1866 painting, Near Andersonville—one of the artist’s most striking, yet least-known works – to discuss the tumultuous final two years of the American Civil War.An emeritus Professor of History at Duke University, Wood was in residence at Washington College from April 23-30 as the Starr Center’s 2011 Frederick Douglass Visiting Fellow. He is the author/editor of six books, including Black Majority (Knopf, 1974), which set the stage for a new generation of scholarship on American slavery.

    Students in the Ichthyology class at Washington College, taught by Dr. Martin Connaughton, observed and experimented with male Betta fish and their displays of aggression. Students learned the different signs of aggression (opercle expansion, lateral display, approach, fin spreading, etc.) that a male might exhibit in order to intimidate an opposing male, an object outside the tank, or even its own reflection. After observing their behavior, students developed their own experiments to determine the impact of factors such as fish size, fish color, and opercle size on the fish’s display of aggression.

    The Ichthyology students observed Zebrafish larvae exhibiting positive phototaxis, a tendency to move towards the light. In this experiment, half of a glass tank was covered in foil to create dark conditions and students watched as the larvae settled themselves in the lighted portion. Check out video from this lab.

    The Student Environmental Alliance planted over 400 green flags in the median between Bunting Hall and Larabee Arts Center representing those individuals who have signed the green pledge for campus sustainability.To help increase campus awareness of climate change, SEA members drew a chalk line around the perimeter of the Toll Science Center to illustrate the anticipated global sea level rise by the end of the 21st century. Alumni networked with students and community members in the McLain Atrium prior to a panel discussion on environmental careers moderated by Interim Director of the Center for the Environment and Society John Seidel. The EnviroPanel featured a mix of alumni from conservation organizations, academia, government, and business: Bruce Alexander ‘94 M’00, Katy Bishop ‘04, Thomas Hopkins ‘86, Andrew McCown ‘77, and Michael Scozzafava ‘02.
