TUPELO – A crowd of third-graders eagerly stared at a table at Lawhon Elementary School as Tupelo High School juniors Tyler Crosswhite and Mary Larkin Rumbarger placed a hard-boiled egg atop a glass vase.
Too wide to slide down the vase’s neck, the egg sat in the top of the container. Mary Larkin then removed the egg while Tyler set a strip of paper on fire and put it into the vase. When the egg was placed back on the vase this time, it fell to the bottom of the container.
The Lawhon students cried “ooh” and “ah,” and the high-schoolers explained how a pressure change sucked the egg down.
The demonstration was one of many held during this week’s Celebrate Science event at Lawhon. Tupelo Middle School teachers Holly Bailey and Judy Harden visited the school on Monday and Tuesday to conduct science experiments with third- to fifth-grade students.
Tupelo High School teachers Sherry Lataham and Monica Rowe came with 10 students to do the same on Wednesday.
“This is a great way to gear up for our science fair on Feb. 16,” said Marty Clark, the instructional coach at Lawhon. “We’re hoping the children will be excited about this and decide they will be a part of our science fair.”
The event was sponsored by the school’s Parent Teacher Organization. It was the brainchild of PTO member Mary Thomas, who coordinated a similar event at Church Street Elementary two years ago.
Thomas and other PTO members helped establish a new science lab at the school earlier this year. The parents staff the lab on Tuesdays and Thursdays and provide materials so teachers can bring their students to it for experiments.
“We want kids to fall in love with science,” Thomas said. “It can be an intimidating subject area, especially if you just read a chapter and answer questions at the end of the chapter. Kids love hands-on experiments.”
On Wednesday, the high school students also led experiments about plants, animals, chemistry and genetics.
