GANADO, ARIZONA – For LaBelle LaFrance, a student at Ganado Middle School, the school science fair was a foray into her potential career.
At the Ganado Unified School District’s Middle School Science Fair on Feb. 9, she presented the findings of an experiment she conducted to see whether students would more easily remember sequences of words, sequences of numbers, sequences of shapes, or sequences of colors. LaFrance said she wants to become a doctor when she grows up, and her interest in the subject came from her specific interest in the human brain.
For her experiment, she made flashcards with numbers, words, shapes and colors on each. She then laid the cards out in a sequence of numbers, words, shapes or colors, and gave the subjects a few seconds to memorize the pattern, and she recorded which patterns the subjects could most easily remember.
“I got these index cards, and I tested kids in primary, elementary, middle school, high school, and older,” she said.
Her hypothesis was that the students would find the color sequences the easiest, but instead they found the word sequences easiest to remember. Though her hypothesis didn’t bear out, she has a research question in mind for her next experiment.
“Which one do they remember faster: colors, numbers, shapes or words?” she asked.
