Students at Sand Hill Elementary had a visit from the Mobile Discovery Center on Tuesday.
The MDC is part of a partnership between the U.S. Army and the National Science Center to bring hands on science exhibits to schools.
Fifth graders attending the lesson covered electricity as part of the lesson. Call Marschall conducted the lesson for the fifth graders, talked to the students about states of matter, and asked for a volunteer.
Jordan Saxon volunteered and demonstrated how electricity is conducted around the body. Marschall moved a light around Saxon as she placed her hand on a plasma ball.
He explained direct current and alternating current to the students.
To show alternating current, Rebecca Bragg held a lightbulb. D’Angelo Housey held a long light while holding Bragg’s wrist, and Zacari Thompson and Laure Barday held long lights close to Bragg. As Marschall placed the AC current to the light bulb in Bragg’s hand, all of the lights around her lit up.
Sherri Turner, technology teacher, said the school was on a two-year waiting list to bring the MDC to the school.
“It was worth the wait,” Turner said.
