Adeline Rang and Kalista Wales were named National Champions in the FFA Agriscience Fair, Environmental Systems and Natural Resources Division 4, at the 91st National FFA Convention which was held in Indianapolis, Indiana this October. Their project was titled, The Effect of Tire Particles on Ceriodaphnia Dubia, and they looked at the toxicity of tire rubber particles on aquatic microorganisms. Adeline and Kalista won their division at the State Agriscience Fair last spring. This allowed them to submit a written report to National FFA and after being judged over the summer, the top 12 projects based on written report score were invited to present their work at the National Agriscience Fair where they were named the winners in their division. Adeline and Kalsita were part of a group of 11 Sumner FFA students who were all National Finalists in the agriscience fair and ended up with final rankings between 5th and 11th in the country. There were over 67,000 FFA members and guests at the National Convention this year, setting a record for the largest conference in the organization's history.
