Germs and suds were involved in Morgan Craig and Blake Wilson’s winning projects in Henry County Schools’ elementary science fair Wednesday at Carver Elementary.
Morgan, a second-grader at Drewry Mason Elementary, won first place for grades 2 and 3, and Blake, a fifth-grader at Drewry Mason, won first place for grades four and five.
Alex Scott, a second-grader at Mount Olivet Elementary, placed second and Delaney Burris, a third-grader at Drewry Mason, placed third for grades 2-3. Isaiah Neal, a fifth-grader at Rich Acres Elementary, placed second and Jonathan Dominguez, a fifth-grader at Sanville Elementary, placed third for grades 4-5.
Several hundred people viewed the projects submitted by the more than 80 school-level winners and attended the awards ceremony.
Morgan’s hypothesis was that hand soap would kill germs better than hand sanitizer or antibacterial soap, Morgan and her dad, Billy Craig, explained in an interview.
The hypothesis was tested by rubbing a Glo Germ gel on the hands, washing the hands with hand soap/hand sanitizer/antibacterial soap, and then shining the hands under an ultraviolet light to discover the remaining germs.
Antibacterial soap worked best, Morgan said.
“She definitely liked it and got into it,” Billy Craig said of the project.
Blake set “to find out why my shampoo does not lather very well when I shower at my house, as compared to when I shower at my grandma’s house,” his project stated. He compared well water, Public Service Authority water, bottled water and distilled water to find out which would lather best. He concluded that his well water does not lather as well as the other types of water. “Distilled water will lather the best because it has no minerals,” he wrote.
Doing the project, “I learned about science and public speaking,” Blake said in an interview.
Students not only had to identify a problem, gather data, formulate a hypothesis from the data and test the hypothesis, but they had to make a presentation about the project, schools Superintendent Jarred Cotton said. He added that a number of excited students at the science fair wanted to show him their projects. “I found myself wanting to find out (their conclusions).”
One of the things Blake learned about was variables, said his mother, Samantha Wilson, a science teacher at Magna Vista High School.
Other projects ranged from the effects of a tsunami on land, to comparing how various types of surfaces affect how high a basketball will bounce, to determining whether eco-friendly cleaners or chemical cleaners clean better, to determining whether cats are right- or left-handed, said Liz Motley, elementary curriculum facilitator for the district.
