What Is the Effect Food Has on Vocal Range?

CSEF · 2010 Human Biology (Junior Division Only)

Shelby N. Smith · Grauer School, The, Encinitas, San Diego County

Overview

Objectives/Goals My experiment is the effect food has on vocal range. Methods/Materials I tested this with peanut butter, soda, and chocolate. I measured a person's voice by using the piano and then gave them one of the foods and measured it again and then repeated for each food. Results The results I got did not match my hypothesis. Chocolate had the least amount of effect on the vocal range. Next was peanut butter and the last one was soda. Conclusions/Discussion If this experiment were to be retried I would suggest more subjects.

Summary statement
