Wartburg College’s eighth annual Physics and Chemistry Demonstration Show will offer science entertainment for all ages Saturday, Feb. 21, at 7 p.m., in the McCaskey Lyceum of the Saemann Student Center.The event, hosted by the Wartburg Chemistry Club, Engineering Club and Society of Physics Students, is designed to engage children and adults with exciting applications of physics and chemistry concepts.Demonstrations include liquid nitrogen, exploding balloons and a sled race using fire extinguishers. Students and faculty will present hands-on activities in the McCoy rooms in Saemann Student Center for 30 minutes before and after the show.

For the first time, the event also will be available live and on demand via the college’s live-streaming network, Knight Vision, at www.wartburg.edu/knightvision.

“We decided to live stream this year’s event due to the popularity of the show in previous years, and we wanted to engage not only the Wartburg-Waverly community, but schools and students across the state of Iowa,” said Christine DeVries, associate professor of chemistry.

Teachers are encouraged to have their students watch the show as a classroom assignment or extra credit opportunity.

“We really want this year’s demonstration show to be an extension of our classrooms here at Wartburg,” said Benjamin Bousquet, associate professor of physics. “It is important that we find unique and interesting ways to engage young people in math, engineering and the sciences. We feel multimedia and live video is one way we can do that.”

Teachers interested in making the demonstration show part of their curriculum can register their classroom at www.wartburg.edu/demoshow. Registrations must include the teacher’s name, school, class and number of students. Teachers will receive brief lesson plans linked to state standards to accompany the program and demonstrations.
