CLAREMONT – Honors biology students at Stevens High School shared the results of their fall semester's research at a poster session held in the high school library Tuesday. 

A poster session is a common way for scientists to share the results of their research with each other and with the public. Their data, methodology, conclusions and references are all shown on the poster. Viewers study the posters, then ask the scientists questions about their research. 

Laiken Becker, Emily Herbert, and Alexandra Perez tackled “Caffeine's effect on cognitive speed” by dosing subjects with 300 mg. of a caffeinated drink and having them complete a cognitive speed test. They charted two lines: “before caffeine” and “after caffeine” to measure the difference. Coffee and Red Bull had the greatest effect on cognitive speed, compared to tea, Mountain Dew, and other caffeinated beverages. 

Joshua Shuey, Joshua Treadway, Lucas Bellimer, Eric Martinez studied the effect of different cleaning fluids on the growth of bacteria, and Tabitha Randall measured how heat affects battery life.

Aunnah Shepard and Olivia Diley experimented with different solutions to preserve cut flowers. Tap water, they found, leads to the fastest wilting. Water with sugar and cider vinegar preserved flowers the longest: eight days. 

Madison Bonneville studied how color affects mood, surveying her subjects to find out how they felt viewing four different colors. 

Amanda Whittemore's research topic was, “How does tempo of music affect the ability to retain a language?” Many of the students found their research led them to more questions, or gave surprising results. Whittemore found that females retained language better than her male subjects. Music with a faster tempo did seem to improve the ability to retain new language, she said.  

Brady Moote, Nolan Ashe, Zoey Foote tested tap water and a variety of bottled waters to find out which was the cleanest to drink. They tested for total dissolved solids and salinity, finding that Poland Spring was the cleanest of the group (they used distilled water as a control) and Fiji water, a popular brand, had the highest salinity and solids. 

Prescott Herzog and Gabby Savo wondered how motor oil would affect snail growth. They added small amounts of oil to the snails' tank water, a tablespoon per day. There was no opportunity to study growth rates, however, because on the fourth day all the snails were dead. 

“We felt bad for the snails,” they said.
