Fourth-grade students displayed their projects during the science fair at West Boulevard Elementary May 16. The students have been working on their projects since November.
Every project at the fair include a question, research, hypothesis, materials, variables and the results. The projects then explained the steps they took in conducting the experiments.
Christian Ortiz created a combination bottle that allows you to apply ketchup and mustard at the same time, or separately.
“Will a combination bottle be more convenient than single bottles?” He asked.
Emily Rutledge displayed a solar cell that powered a lightbulb and a solar panel that charged a cell phone in the sun.
Marco Stilliana’s project “Bouncy Polymer Chemistry” was all about silly putty. He asked what makes silly putty bounce and discovered that the answer was the molecules. Stilliana then used Elmer’s Glue, Borax, a bowl, a plastic bag and food coloring to create his own silly putty.
Alyna Cuevas’ project tested which substance would preserve an apple the best. Out of Epsom salt, baking soda and table salt Cuevas found that table salt would preserve the apple.
Jacob Spin’s project “Amazing Polymers” showed how polymers can help conserve water when taking care of plants.
“If you’re a person who forgets to water your plants, polymers are your lifesavers,” said Spin.
Fatima Rehman discovered slime will stay slimier in a bag opposed to leaving it out because the bag traps the water inside.
Jen Cabuno, science teacher said the science fair is a great event for the kids.
“It’s important for them to know how things work and why they work,” said Cabuno.
