Inspecting his classmate Robbie Breininger’s experiment, senior Timmy Nguyen records the number of worms that reside in the handmade aquatic environment. “I chose this experiment because I was intrigued by the dramatic decline of sea grass in the year 2011, and I wanted to investigate the cause,” Breininger said. “I thought it may have something to do with environmental co-variants in aquatic environments.” At the start of the year, science research students choose an experiment that they work on for many months and take to the science fair in March.
