Shooting for the moon
Wadena-Deer Creek fifth-graders were inches of Plexiglas from touching a piece of the moon on Wednesday afternoon.
Dr. Duane Sea, a retired professor from Bemidji State University, was a special guest on Wednesday afternoon, giving three 40-minute presentations and hands-on learning.
Sea worked for NASA from 1967-1968 and taught physics at Bemidji for more than 30 years.
His son is Dave Sea, one of the teachers at WDC Elementary.
Sea gave an overview of the history of the space program and gave laboratory demonstrations showing how chemistry and physics relate to rockets and space travel.
And liquid nitrogen is much colder than Minnesota air, as any students who volunteered to stick their fingers into the smoky flask found out.
Duane Sea's daughter Debra Sea presented a rock from the moon encased in Plexiglas and held in a safe. She said it is usually loaned to museums.
"It's considered a national treasure and it's priceless," Debra Sea said.
Debra Sea is working on an experimental film "Moon Rock" as her master's thesis in film for University of North Carolina at Greensboro.
Duane Sea said he has been to schools before, with the largest audience being 5,000 students in Chicago. He said the visit to WDC was the his first school visit in years.
