Q: Is perlite a permissible material as insulation? (Section: 3; Pargraph: a; Line: 2)
A: No, perlite is a foam and is not allowed.
Q: Is styrofoam considered to be a type of foam? (Section: 3; Pargraph: a; Line: 2)
A: Yes, styrofoam is a foam and not allowed in the devices.
Q: Whose thermometer is used for the final temp since the supervisor must supply thermometers/probes and paragraph 4a iv says teams may utilize their own thermometers to measure the starting water temp in their beakers? (Section: 2; Paragraph: b; Line 2)
A: Supervisors provide the thermometer for final temp measurement.
Q: Can teams be penalized for submitting a graph containing more than four data plots? (Section: 2; Paragraph: b; Line 1)
Q: Are we allowed to have in our binder more than the required up to 4 graphs that will be handed in? (Section: 2; Paragraph: c; Line 15)
Q: Are calculators (programmable in particular) to be impounded? (Section: 2; Paragraph: d; Line 1)
Q: Is impound only for Part 1 of the event (device, tools, notes, plots, etc), or is the binder for Part 2 also to be impounded? (Section: 2; Paragraph: d; Line 1)
A: Rule 2.d. explicitly states that notes must be impounded. This includes note for both Part 1 and Part 2.
Q: Can duct tape be used? (Section: 3; Paragraph: a; Line 1)
Q: Can my team use duct tape completely around the outer edge of the lid to secure it? (Section: 3; Paragraph: a; Line 2)
A: Yes, General rule #2 applies: http://soinc.org/ethics_rules
Q: Should the students be allowed to place a separate "plug" or "cap" into or on the opening of the internal 250 mL beaker before closing the device? ( (Section: 3; Paragraph: b; Line 1)
A: Yes, teams may put a "plug" or "cap" on the opening of the internal beaker. Anything put in or around the beaker cannot physically modify the beaker nor the water in the beaker. The required hole for the probe must be at least 1.5 cm in diameter in any plug or cap. The device does not need to be all one physically attached unit.
Q: How late is the team allowed to insert a thermometer to measure starting temperature after the inside beaker was placed in the container? (Section: 4; Paragraph: a; Line 5)
A: This will be up to individual event supervisors, but it should happen as soon as possible so as to not violate the overall spirit of the problem.
Q: Are event supervisors supposed to supply the ice-water, or do students need to bring in their own? (Section: 2; Paragraph: b; Line 1)
A: Yes, Event Supervisors provide the ice-water.
