Our congratulations go to Anna Ward, a fifth grade student at St. John Neumann Catholic School, for winning the Ijams Prize at this year's regional science fair.
Ward's experiment was titled "What are Fronds "Frond" of?
Dr. Louise Conrad, judge for the award, says that Anna wanted to determine if duckweed—a small floating aquatic plant and the smallest flowering plant—was an indicator of water quality. She floated 100 plants in each of several different containers. One container held fresh water, the others had water from the same source but that had been fouled by a variety of different pollutants: detergent, motor oil, fertilizer, etc.
After a week, Ward counted the number of plants that remained in each container.
A simple experiment that yielded a very observable answer and that is the way science works.
