Metric Mastery

(section: 3 / sub-paragraph: ii / line: 2)

2013-11-04 01:50 The "plus one estimated digit" rule only applies to analog equipment, not to digital, right? Students should not be estimating digits on a digital scale, digital thermometer, etc. Correct?

Correct. You can not estimate a digit on digital measuring devices.

(section: 3 / paragraph: c / sub-paragraph: iii / line: 1)

2014-01-07 01:30 Can we use scientific notation in our answer?

Yes, proper scientific notation will be an acceptable format for an answer in the Metric Mastery event.

2014-01-07 01:45 Does the "plus one estimated digit" rule apply to a vernier caliper? One of markings on the vernier scale is supposed to be exactly “aligned" with a marking on the main scale which will gives the exact reading.

No, you are correct. On a vernier caliper there would not be an estimated digit.

Rotor Egg Drop

(section: 1 / line: 3)

2014-02-28 16:45 Are feathers allowed as an attachment to a homemade wing or blade?

Yes

(section: 3 / paragraph: a / line: 1)

2014-02-28 16:47 In the sentence, "The device must use wings or blades that rotate around a central axis to slow the descent of the egg", does the "axis" have to be a physical axis (like an axle) or can it be conceptual axis (like the earth's axis)?

Either conceptual or actual is acceptable.

(section: 3 / paragraph: e / line: 1)

2013-12-19 13:54 Does the statement at the device must fit inside a 51cm cube in any orientation mean that the device must be able to rotate in all directions inside the cube? I don't understand the intent of the "any orientation" phase.

The entire device (with the cup), in both launch and flying configuration, must fit into a 51 cm cube in any orientation the student chooses. The entire device does not have to rotate in the 51 cm cube when it is being measured it just has to fit within the cube.

2014-02-28 17:12 Must the device be able to fit in the cube in any orientation the judge chooses? "Any orientation" could mean if it can be fit, it passes or that all orientations must fit.

Students will be the ones who choose the orientation of their device in the cube and place it in the cube for verification. Students must be the only ones to touch their device. As long as it fits into the allowed dimensions of the cube,in flying configuration which means with the cup attached, then it passes.

2014-02-28 16:56 Does the rotor have to revolve around a central axis a minimum of onerevolution? How is revolution defined (approximately onecomplete turn to be determined by event supervisor?)

The rotor should rotate at least once around a central axis or it could be determined to be a parachute or glider. It will be up to the event supervisor to determine whether the device has rotated around the central axis.

2014-02-28 17:05 If the students' rotor design does not encourage parts other than the cup to hit first, will the students be tiered if the cup is not what hits first due to causes out of their control such as air drafts/currents?

Students will be placed in Tier 3 or 4 if the cup does not hit first. Construction 3.d. "No other shock absorbing or cushioning materials can be used..." If another part of the device hits first it would act as a shock absorbing material.

2014-03-09 20:13 Are abbreviations allowed to be concatenated? For example, if one has defined N = north, and E = east, is NE -> northeast valid, or will it be penalized?

Yes, this is allowed as long as each part is correctly defined.

(section: 2 / paragraph: b / line: 3)

2014-03-10 01:11 It is stated that any single letters or words may be used. However, do those words have to be in English. Specifically, are students allowed to use letter combinations that correspond to chinese characters (pinyin)?

The standard English keyboard is identified for use with all Science Olympiad tournaments. However, each tournament may - at their discretion and announcement to competing teams - provide additional or alternate languages that may be used. If the PC standard 101 keyboard is able to make Chinese characters, this would only be acceptable if the event supervisor has identified non-English language may be used. For nationals, English is the identified language. Using keyboard symbols to create non-English words will not be acceptable.

(section: 2 / paragraph: b / line: 7)

2014-03-10 01:03 In Write it Do it, it says you can use any symbols on the PC standard 101 key keyboard. On that keyboard there is an "and" symbol, can the and symbol I make look different than the one on the keyboard, or does it have to be the same?

As long as what is written is readily apparent it refers to the "and" symbol and not something else, it would be accepted. Keep in mind that the "+" is not the same as the "and" symbol.

(section: 3 / paragraph: d / line: 1-3)

2014-03-10 01:07 Will a penalty be assessed for abbreviated fractions (e.g., 1/2 for "one-half")?

No, fractions may be referenced as 1/2 or 3/4 etc.
