Walker Middle School students learned about several different science discoveries recently, as one of the mobile exhibits from the National Science Center in Augusta was in town.
With instructor Cal Marschall at the helm, students in grades 4, 6, 7 and 8 couldn’t help but have fun as they also learned about the power of sound and the uniqueness of electricity.
In a controlled atmosphere, Marschall demonstrated the power of sound and emphasized how people need to be aware of how important their sense of hearing is and not to do anything to jeopardize it.
“Doctors have been able to replace just about everything in the human body, but the ear and the brain, they haven’t been able to,” Marschall said.
During the sound demonstration, Marschall showed how sound could be used to break glass said it is even strong enough to bend metals.
After the demonstration with sound, Marschall’s used several different tools to demonstrate how electricity can pass through the body and described its usefulness.
Seventh-grade teacher Sabine Little organized the special day and said “This was set up to expand their knowledge and to show them some different aspects in regards to science.”
According to Marschall, the exhibit travels all throughout the US and is on the road 10 months out of the year.
“We go all over - to any school who wants to set us up, to the Boy Scout (National) Jamboree, to summer programs, you name it and we’re there,” Marschall said.
He noted the program is funded through the National Science Center in Augusta and through the US Army.
