Whenever we go to a competition, one of the teachers is always ready w/ scientific calculators, splash goggles, and aprons. Hopefully your school already has these materials, but if not, these are easily the most important resources. Most of the times, students forget about the safety stuff until the very end, and so when a teacher is supplying these items, it's one less thing for the kids to worry about.
