“We have four categories for each grade level,” said event committee chairwoman and third grade teacher Hilda Rios.
The winners were:
• Kindergarten to first grade — Mary Joyce Espinosa, first place; Joanna Gadiane, second place and Mariechrist Castro, third place.
• Second and third grades — Denise Bicera, first place; Leandro Bichayda, second place; Andrea Roberto and Christian Castro, third place.
• Fourth and fifth grades — Czarinna Posadas and Cristina Ruiz, first place; Reynafe Aniga, second place; and Ruth Pangelinan and Jiana Dela Rosa, third place.
• Sixth grade: Jake Madamba, first place; Rhea Banados and Christine Aninzo, second place; and Stefficate Alipio, third place.
The five projects chosen for the islandwide competition were submitted by Mary Joyce Espinosa, Denise Bicera, Leandro Bichayda, Czarinna Posadas, Cristina Ruiz and Jake Madamba.
Espinosa’s project proved that detergents are harmful to plants.
“I poured three types of detergent on three plants in different pots. The plants died,” she said.
She wants to win the islandwide competition because her mother promised to take her to McDonald’s if she gets a prize.
Bicera’s project is about which fertilizer would be best for tomato plants.
“I concluded that wastewater from the fish is the best fertilizer compared to just water and vegetable skin with water. The nutrients from the fish are helpful because the plant grew taller,” she said.
Bichayda’s project is “Lava in a Cup.” “My project is about how to make lava. It took me three days to do my project. I searched the Internet for it,” he said.
Posadas and Ruiz’s project proved that a smelly foot can cause bacteria to grow.
“First we made a gelatin to rub a cotton swab after we rub it on our sweaty toes,” Posadas said.
“Then we put on shoes without socks to make our feet sweaty. When the gelatin was hard, we had to take off our shoes and rub the cotton swab between our toes. Then rub the swab on the jar with gelatin. Put the jar with gelatin in a warm dark place. After four days we saw molds and microbes,” she added.
“We learned that we always have to shower and not to always get dirty because bacteria are going to grow on you,” Ruiz said.
Madamba’s project is “Two in One Sand Sack,” which aims to “help the environment.”
“In my sand sack you can plant seeds and put it anywhere. It can absorb 80 percent of water,” he said.
Rita Carreon, event committee co-chairwoman and kindergarten teacher, said the projects must have a problem, hypothesis, result and conclusion.
“The students must be creative and organized,” she added.
The judges during the competition were Tobed Smith, retired principal; Merely Yamazaki, retired teacher, Manny Borja and Leilani Sablan of the Division of Environmental Quality; Chailang Palacios, retired government agency employee; Bob Coldeen of KSPN; John Moreno of the Department of Public Health; Sibylla Guerrero, SAES reading resource teacher; and Daisy Villagomez, SAES counselor.
J.G. Sablan Ice & Water Company donated eight bags of ice for the Science Fair.
