Jacob Hill explains his research on Nick Saban and Bear Bryant.
Two hundred budding scientists presented their experiments and results at today's STEM Expo at Shades Cahaba Elementary.
The STEM Expo, previously called "I Wonder Why?" was a collection of independent research projects by K-5 students, based on STEM (science, technology, engineering and math) education standards. The projects that students presented covered a wide variety of topics.
Some of the research, which students presented to judges on March 9, was more scientific, such as studying high and low air pressure, plant growth, salamander eggs and the science behind gymnastic movements. Other projects were a little more lighthearted, such as which brand of bubble gum creates the biggest bubble, or studying Pokemon video games.
Fourth grader Anna An did her research project on whether fingerprints are similar in members of the same family. With her mom's help, Anna even contacted relatives in China, who mailed her photos of their fingerprints to compare. Anna said she did discover that fingerprints have similarities due to genetics, and she enjoyed learning about them.
Fellow fourth grader Dorian Sanchez studied the effect of high and low air pressure on aircraft and how planes take in and expel air. Though Shades Cahaba has held similar expos in the past, he said it was his first time to participate.
"I was just too nervous to do it in third and second [grade] and kindergarten," Dorian said. "But in fourth grade I learned so much that I could just do it."
Dorian said he hopes to participate again next year.
The judges awarded 129 gold ribbons and 61 silver ribbons to outstanding projects, based on students' use of the scientific method, creation of a results report and their ability to explain their project to a judge.
Parents will be able to view the expo projects at Parent Night tonight, and the rest of the Shades Cahaba student body will visit the expo from 8 a.m. to noon on Friday, March 10.
