Indiana Academic Super Bowl Science Round 2017 – Senior Division – Invitational 1 A Program of the Indiana Association of School Principals Emcee: Please remind proctors that there should be a copy of the Periodic Table with the values of the Ideal Gas Constant included at their table for student use in the Science and Interdisciplinary rounds Students: Throughout this competition, foreign names and words may be used. If there are any discrepancies between how a word/phrase should be pronounced and what you see on the screen, the screen supersedes what is spoken. Emcee: Please ask Proctors to check student calculators at this time. The only calculators allowed during this competition are the following models: TI-30Xa and TI-30X IIS If someone at your table has a different model, raise your hand for a procedural official.
