LOCKPORT, NY -(WKBW)-
Science Day was recently celebrated at George Southard Elementary School in Lockport, and all classes participated with special science related events, as well as the opportunity to participate in specially planned science experiments and observation.
"Our second grade experiment was a lesson on matter, liquid combined with a solid, and to compare the differences in the density of salt water versus fresh water," said Teacher Susan Gmerek. "After the students made predictions, they added salt to one of the glasses of water to change the density of it, and then they added egg yolks to both the freshwater and the salt water, which showed how they float easier in salt water compared to fresh water, since salt water is denser."
In fifth grade classes at the school, students hosted a special program by chemistry students at SUNY Buffalo who conducted experiments using student volunteers. "The fifth graders really loved an activity the U.B. students did that included demonstrations in all fifth grade rooms. One included using chemicals to set dollar bills on fire, comparing the way the chemicals produced different looking flames and so forth, another used liquid nitrogen to freeze things and then break them. The kids love it," said Teacher Paul Zuccari. "We started doing this last year and the students really get a lot out of it. It always makes such an impact in supporting the in-class lessons that we have as part of the science curriculum. They are able to present activities that we aren't able to do in class."
