Brian Stewart, associate professor pf physics, demonstrates how liquid nitrogen looks like water but evaporates rapidly at room temperature. Fifth grade students from Snow Elementary School toured the Wesleyan sciences June 19.
Vacek Miglus, lab technician and curator of the Physics Department, shows the students how various lamps are lit by a Tesla coil without being attached to wires. Brian Stewart is on the right.
Laurel Appel, adjunct associate professor of biology, senior research associate and director of the McNair Program, watches DNA fibers come out of a solution as ice-cold alcohol meets the warm, salty, DNA solution. One of the students described the reaction as looking like a spiderweb.
McNair fellow Kelley Miller '10, at right, helps the Snow Elementary School students isolate DNA from wheat germ. The recipe for this, and other experiments is online at http://lappel.web.wesleyan.edu/expts.htm.
