Mar 7, 2012 - By Emily Etheredge, Staff WriterFifth-graders at Rendezvous Elementary School entered 124 projects in their annual science fair Thursday. The areas of study for the projects included zoology, botany, physical science, health, chemistry, energy, thermodynamics, consumer science, earth and space, mechanical engineering and kinesiology.
Members of the National Honor Society at Riverton High School, retired teachers, and community volunteers made up the panel of 51 judges interacting with the students and learning about the projects.
Fifth-grader Katelyn Slack wanted to figure out which brand of popcorn popped the most in a bag. After testing three different brands -- Jolly Time, Pop Secret and Orville Redenbacher -- Slack found that Jolly Time popped more kernels because it had more butter contact.
Titling her project, "Mr. Popper's Popcorn" Slack said her reasoning for trying to figure out how many kernels were popped in a bag was because of her love of popcorn.
"I love eating popcorn and wanted to know which brand would give me more popcorn to eat when I popped it," Slack said.
Kami Bolte researched flowers and the variables that might keep her flowers from wilting quickly. She originally did her project using red tulips but displayed red carnations at the fair Thursday. Testing the flowers in solutions such as water, water and sugar, and water with pepper, Bolte found that using water and sugar kept the flowers fresh. She said she will use this solution when making a bouquet of flowers.
"When I put the flowers in pepper water they did the worst, but it was helpful for me, because whenever I pick flowers I always want to make them last longer," Bolte said. "Through this experiment I was able to find out a way to keep them fresh."
This year, the students completed a majority of their projects at school, which let teachers observe the students as they planned their projects, completed the experiments and designed their display boards. The students were also allowed to team with another student to complete their project. Projects were awarded ribbons based on evaluations and interviews with the students.
Rendezvous Elementary science teacher Bill Reiter said he was excited about the science fair and felt the students had worked really hard on the projects they were presenting.
"Everyone has worked really hard this year, and we are excited to be able to showcase their talents," Reiter said.
