Some things to remember are that tables in the discussion rooms generally can not be used for EOH projects since classes are held during EOH, and the Physoc office has a few extra extension cords and power strips in case the number requested is not enough. Presenters should know what they are talking about, speak loudly and clearly, be able to run the equipment, and be able to answer questions. Be aware that some projects desperately need more than one person to run things smoothly, e.g. the bubble room works best when there are more than 3 people helping out. Safety inspections are the first thing that happen on Friday morning. Make sure that the project leaders are at Loomis ON TIME because sometimes the safety people show up early.
Same thing goes for judging.
Friday is always the busier of the two days of EOH because that is when all the schools take field trips to see the cool science stuff, so be prepared to be overwhelmed by a mob of excited screaming kids, especially around late morning, noon, and early afternoon.
