CollapseEvent Name: Anatomy
 11/13/18 9:00 AMNational FAQ: In this section, I am told to interpret ECG readings on strips. However, there are many complicated heart conditions that can be read on ECG strips. I'm wondering whether we have to know about all of these heart conditions or just a few basic ones.ECG interpretation will be simple and straight forward for B division. It is more about understanding how than diagnosis.
 09/21/18 9:00 AMNational Rules Clarification3.a.iii. should read: "Starling's forces in the capillaries"; (not Startling's)
CollapseEvent Name: Battery Buggy
 01/27/19 1:17 PMCan the vehicle-mounted aligning device be a laser pointer which will be removed before the vehicle running?No, please refer to 3.f.
 01/25/19 3:00 PMNational FAQ: Will competitors be allowed to remove the cans from the course prior to each run to set up their sighting device? With the understanding that the sighting device is removed and the cans replaced prior to each run.Yes, this will be allowed.
 01/25/19 9:57 AMNational FAQ: Is a solenoid considered to be a mechanical relay, given that they are both electromagnetic coils with a similar function?Technically, all mechanical relays are built with a solenoid. However, some event supervisors may not know this and you may run into a problem. That, plus "solenoid" is not specifically mentioned in the list of allowable components (rule 3.f.) could result in a construction violation.
 01/25/19 9:14 AMThe rule says Participants may bring but not impound measuring devices and stand alone calculator of any type. Are we allowed to bring Analog or Digital Multi meter to Verify the voltage. Most of the commercially available battery packs go bad or contacts become loose quickly. Since the students has to install the battery before the run, It would be helpful for the students to verify the voltage across the pack before the run. If there is any loose installation they can identify with that. No, please refer to rule 3.f.
 01/15/19 8:33 PMWe saw teams using battery buggies with a laser pointer attached for alignment. Is that permissible? If so, do they have to be attached to the vehicle?No, laser pointers are not allowed. Laser diodes are not one of the allowed components in 3.f., and laser pointers are an electric/electronic tool which is prohibited per 3.f..
 12/15/18 8:40 AMIs it allowed to impound 2 battery buggy vehicles and decide later which one to use?No, rule 2.a. states that "Participants must bring and impound a vehicle"
CollapseEvent Name: Boomilever
 01/22/19 7:39 AMNational FAQ: The parameter states "no portion" may touch below the line which is "more than" 15cm below the hook. Does this imply that supervisors can choose any distance greater than 15cm to draw the contact depth line? Boomilever B & C 3.e. The Contact Depth Line for a Boomilever is set at Div. B - 20 cm and Div. C - 15 cm. This is a set distance and will not vary between tournaments. All tournaments will have the same contact depth distance.
 01/22/19 7:32 AMNational FAQ: Does the 6 minutes include "placement verification time"?No, the 6 minutes should not include time taken by the Event Supervisor to verify the placement, although any corrections that need to be made will count as part of a team's 6 minute.
 01/22/19 7:24 AMNational FAQ: Boomilever.5.b.ii. states:"ii. ¼” threaded eyebolt, no longer than 3”, and a ¼” wing nut"Does the 3" include the eye or just the rod/threads that extend from the eye? Is there a minimum length of the threaded eyebolt?The 3" threaded eyebolt refers to the labeled length at purchase. There is not a minimum length of the threaded eyebolt.
 01/21/19 1:13 PMHow will students be allowed to load sand? During the past few years, students were always allowed to hand- load, but this year, will it change to auto-loading?Participants should be prepared for either loading mechanisms. Teams require stepping stools to reach the test apparatus may check them in with the event supervisor from 7:15 to 7:30 and retrieve them at 3:00 PM. Stepping stools may be used by other teams.
 12/05/18 10:30 AMNational Rules Clarification 3.e. should read: "Before and throughout loading, no portion of the Boomilever may touch the testing wall below the Contact Depth Line which is 20 cm (Div. B) or 15 cm (Div. C) below the center of the hole for the Mounting Hook (5.a.iii.)." ("more than" has been removed from the text.
 11/16/18 8:00 AMNational FAQ: If Wood is turned into wood string, would that still qualify for build materials?No, string made from wood can not be used.
 10/25/18 9:12 AMIs the loading block considered one piece, or are you allowed to remove the threaded eye bolt and wing nut from the loading block to mount it on the boomilever, and re-connect the threaded eye bolt and wing nut after mounting?The "Loading Block" is only the square block with the hole (5.b.i.); it is separate from the threaded eye bolt and wing nut (5.b.ii.). Both are components of the Loading Assembly (5.b.), which, per 4.Part II.c., is allowed to be disassembled.
CollapseEvent Name: Circuit Lab
 01/25/19 10:01 AMNational FAQ: Don't questions concerning the "electrical characteristics of a silicon PN junction" count as questions involving semiconductors, which is a topic "not included in the competition" according to 3. d.?PN Junctions, Operational Amplifiers, and diodes are allowed for Division C and LEDs are allowed in limited capacity for Division B, no other semiconductors devices are allowed other than stated by rules.
 01/25/19 9:19 AM3.d. says "AC circuit theory" is not included but 3.c.iv includes "AC characteristics". What's the difference between "AC circuit theory" and "AC characteristics"?AC Circuit analysis is not allowed, but AC characteristics such as knowing why they are used for power transmission and the dangers of AC current would be allowed as AC characteristics. What is meant in 3.I.c.iv is the characteristics (or properties) of AC electricity, which is an included topic. AC circuit theory, which is not included, involves methods of analyzing circuits with capacitors, inductors, transformers that behave differently for DC and AC. In general, theory items delve into more technical analytical techniques (e.g. phases differences and power calculations, etc.), while characteristics are more general knowledge (e.g. typical frequencies and transmission voltages, etc.).
 11/16/18 8:21 AMNational FAQ: Define the word "Basic." What is considered a Basic Multimeter? What is not considered a Basic Multimeter? Could it be digital? Auto ranging? What part is discretionary?Basic multimeter refers to those devices that are hand-held, battery powered, analog or digital, manual or auto ranging, measuring volts, amperes and ohms. Multimeters with advanced features, such as graphing, time waveform displaying, fft/frequency-domain functions, non-contact voltage sensing, current clamp probes are not considered basic. Whether to allow participants to use their own multimeters is at the discretion of the event supervisor. For example one regional supervisor may allow it, while another regional supervisor may not and require all participants to use multimeters they provide.
 11/16/18 8:00 AMNational FAQ: Are the breadboards mentioned limited to solderless breadboards, or will they involve soldering? Only solderless breadboards will be used.
CollapseEvent Name: Codebusters
 01/25/19 2:32 PMNational FAQ: When encrypting a hill cipher with a 2x2 or 3x3 encryption matrix, what should be done with letters left over that will not fill the encryption matrix? Different sources say to add different letters at the end, but it will change the final answer.For purposes of Science Olympiad, students should always pad an encryption matrix with the last letter in the alphabet (e.g Z for a 26 letter alphabet).
 01/25/19 10:07 AMNational FAQ: What will students be asked to do with respect to the RSA cipher?Students may have to identify formulas for encryption or decryption of data values given one or more computed RSA values, compute the private key given a factored n, compute d given the other 5 RSA computed values, or decode an encrypted value using a given private key. Examples of all of these can be found at https://toebes.com/codebusters/RSAEncrypt.html
 01/14/19 10:43 PMNational Rules Clarification 3.h. should read: "For all questions, the event supervisor will identify which cipher is to be used." ("All but one" was changed to "all")
 12/27/18 1:13 PMFor these questions, will the letter frequencies given on the exam correspond to frequencies of the cipher text or the frequencies of the plain text? We have seen both in practice questions, which can be confusing.The rules do not mention anything about frequencies.
 12/27/18 1:12 PMThe rule states that a Hill cipher question can be asked about "computing a decryption matrix given 4 plaintext-ciphertext letter pairs". The Science Olympiad wiki (https://scioly.org/wiki/index.php/Code_Busters) does not provide a clear example of solving this type of question, and the toebes site (https://toebes.com/codebusters/index.html) does not generate example questions/solutions of this type. We also did not see this type of question on past exams. Should the students expect this question on the exam? How about for division C?Yes, teams should still be prepared for this type of question. They should look at other resources on the Mathematical Cryptanalysis of the Hill Cipher.
 12/05/18 11:43 AMNational FAQ: Are different types ( i.e. pencils, highlighter, pens, etc.) of "writing utensils" acceptable? Yes. pencils, highlighters and pens are all valid writing instruments. However, any solutions written must be readily read by the person grading the test and an answer written only with a yellow or other color highlighter may be scored the same as a non-answered question.
 12/05/18 11:40 AMNational FAQ: Must competitors finish the first question before moving on in order to obtain points for the bonus, or may one or two students move on from the first question while others work on the first question in the first 10 minutes? Rule 3.d states that "participants are free to answer the questions in any order, working individually or in groups, attempting whichever of the questions seem right for them." Therefore, there is no requirement to complete question 1 before moving on to the other questions to be eligible for the timing bonus on the timed question.
 12/05/18 11:37 AMNational FAQ: For monoalphabetic ciphers, is an error defined as per incorrect letter or does one error encompass everything from that letter matching to an incorrect letter? If A is B and if the word AA is translated by mistake to CC is that 1 or 2 errors?..Errors are counted against the decode phrase and not the alphabet. If A is supposed to map to B, then AA mistakenly translated to CC would count as two errors.
 12/05/18 11:33 AMNational FAQ: Does "Mathematical Cryptanalysis of the Affine Cipher" refer to merely decoding a cipher given the a and b values, or determining the a and b values from given ciphertext? Mathematical Cryptanalysis of the Affine Cipher means that the student has to decode the entire plain text of the cipher given two plain text characters to match the cipher text.
 12/05/18 11:29 AMNational FAQ: Will the crib necessarily be provided in the exam?Not for all questions. "cribs" (also known as Hints) will only be supplied for cipher types under rules 3.e.iii.(1), 3.e.iii.(3), 3.e.iii.(5), 3.e.vi, 3.e.vii, 3.f.iii and 3.f.vi.
 12/05/18 11:26 AMNational FAQ: What type of baconian Cipher is being tested, the one in which V and J do not have a unique code or the one where all the letters have a unique code?The Baconian ciphers will use the 24 character alphabet in which I and J are both represented by ABAAA and U and V are both represented by BAABB.
 12/05/18 11:23 AMNational FAQ: Is xenocrypt necessarily monoalphabetic substitution?Yes. All Xenocrypts will be mono-alphabet substitution following the same substitution rules of Aristocrats.
 12/05/18 11:18 AMNational FAQ: For aristocrats with spelling/grammar errors, should the errors be included in the final answer?Yes. The final answer should exactly match the errors in the encoded text. Specifically if the aristocrat was LFOE JG KOI GNFQJH then the correct answer would be HEAR IS BAD SPELIN in order to count as zero mistakes.
 11/16/18 8:23 AMNational FAQ: Are xenocrypts only limited to Spanish? The wording makes it unclear. Yes. For this year, all Xenocrypts will be in Spanish.
 10/06/18 9:00 AMNational FAQ: If students make errors while decoding the first question, but still receive full or partial credit per 4.b.ii., will this be counted as answering "correctly" for purposes of earning the timing bonus? There is no partial credit for the bonus. In order to be considered solved for rule 3.i.v. the team must solve the timed question with 2 or fewer errors within the 10 minute timer. After the 10 minute time has passed, the timed question is scored like any other question under rule 4.b.ii. such that a team may still receive points for solving it with 3 mistakes, but no bonus is awarded.
CollapseEvent Name: Crime Busters
 01/27/19 9:26 AMIt says that the supervisor MAY provide differential density solutions or other method of determining the density of polymers such as plastic. If they DO NOT provide the differential density solutions, will they still ask students to determine the density of plastics? If this is the case, then should students BRING THEIR OWN differential density solutions in their Crime Busters kit so that they can still perform the density determination?No, students should only bring what they are allowed to bring. A penalty of up to 10% may be given if a team brings prohibited lab equipment to the event.
 01/25/19 2:40 PMNational FAQ: Can teams bring spoon straws in their kit for scooping and stirring?Yes, spoon straws would be an acceptable substitution for spoons and spatulas as part of the materials participants bring to the event.
 01/23/19 12:40 PMNational FAQ: Can teams bring pipettes in addition to droppers?Pipettes are a type of dropper and are allowed.
 01/22/19 7:49 AMNational FAQ: The list of equipment for the chemistry events is listed as "recommended". Are the check marks recommended for each event or are teams limited in each event to those items with a checkmark? Teams may have in their kits all the items that are listed as Recommended Lab Equipment for Div. B Chemistry events for any Div. B Chemistry event even if there is not a check mark in the column for that event. Please see https://www.soinc.org/sites/default/files/uploaded_files/RecommendedLabEquip_DivB_121718.pdf The statement at the top of the list for Recommended Lab Equipment for Division B Chemistry Events says: Each team may bring any or all of the items listed below for use in Division B Chemistry Events. Teams not bringing these items will be at a disadvantage as Event Supervisors will not provide Recommended Lab Equipment. A penalty of up to 10% may be given if a team brings prohibited lab equipment to the event.
 01/22/19 6:57 AMRecommended Lab Equipment Form lists several materials in plural form (beakers, flasks, etc). How many of each are allowed?Per General Rule #1, there is no limit to the number that may be brought.
 11/05/18 8:00 AMIn the event parameters it says that gloves are optional and up to the host's decision. If gloves are optional, will the participants be allowed to touch the powders? If gloves are not permitted, how far in advance will the teams be notified? Gloves are optional; San Diego Regional will not require a specific type of gloves for its tournament.
 10/17/18 8:44 AMNational FAQ: Previously, students were allowed to bring in magnets for metal identification. However, in the new recommended material list on the soinc website, magnets are not listed. Are students allowed to bring in magnets in their supply box?Yes, magnets will shortly be added to the list available online.
CollapseEvent Name: Density Lab
 01/27/19 8:35 AMIn the rules manual, some events rule pages (eg. Density Lab) says under Event Parameters " Each team may also bring writing utensils, and two stand-alone calculators of any type for use during any part of the event". But the Calculator Guide in page 38 lists Density Lab under events in which only a "Stand-alone non-graphing, non-programmable, non-scientific 4-function or 5-function calculators" is allowed. So, which of these rules will be applied?Page 38 states that Stand-alone, programmable, graphing calculators and stand-alone non-graphing, programmable calculators can be used for Density Lab. It also says that Stand-alone non-graphing, non-programmable, non-scientific 4-function or 5-function calculators are acceptable.
CollapseEvent Name: Disease Detectives
 01/15/19 8:26 PMI see below comment from FAQ section. Does it mean there will be no questions related to topics : Foodborne, Environment and Population growth? >>>>>> 10/05/18 9:41 AM National FAQ: What is the focus of Disease Detectives this year? Disease Detectives has been reorganized for 2019 and the topic rotation has been dropped. See the 2019 rules for the emphasis in each area. For an outbreak investigation, needed background will be provided. >>>>>> While the focus will not be Foodborne, Environment and Population growth, there may be questions relating to these topic that are relevant to the three parts in section 3 of the rules.
 10/17/18 8:35 AMNational FAQ: Are the steps of an outbreak investigation based on the 13 steps as listed on the CDC site, or on the 10 steps provided in previous years' event description.The updated event outline uses the 13 steps that are listed on the CDC site and in the textbook listed in the resources. It is the most up-to-date format. The process is the same, but the division into 13 steps emphasizes the validation of the hypothesis.
 10/05/18 9:41 AMNational FAQ: What is the focus of Disease Detectives this year?Disease Detectives has been reorganized for 2019 and the topic rotation has been dropped. See the 2019 rules for the emphasis in each area. For an outbreak investigation, needed background will be provided.
CollapseEvent Name: Elastic Launched Gliders
 01/27/19 9:39 AMIs it allowed to launch with just the elastic? (i.e. no handle?) Rule 3i can be interpreted in both ways.Yes.
 01/22/19 7:07 PMHave the room dimensions for the Elastic Launched Gliders event been announced? Ceiling height, etc.?See Tournament updates: https://scilympiad.com/san-diego-so/QnAs/doc/tournament-updates Posted date 9/4/2018
 01/22/19 7:51 AMNational FAQ: If a team launches their first flight in 30 secs. Do they have 5 minutes beginning at the 1st flight to continue or only 4 min 30 sec because the 5 minute period started with the initial minute countdown? The team has a total of 5 minutes for their Flight Period. The start of that 5 minutes is either with their first flight (trim or official) or their 5 minute Flight Period will begin 1 minute after they have picked up their glider from the ground, whichever time comes first. If a team launches their first flight (trim or official) within the 1 minute, there 5 minute time begins at that point no matter how much time elapsed between picking up the glider and the allowed 1 minute.
 01/15/19 8:29 PMAt a regional event over this past weekend my students were instructed to aim their airplane straight at the ceiling (90 degrees) by the judges. Per the statement in the rules "Gliders must only be launched while aimed at any point on the ceiling. Participants must not aim for the walls, spectators, low obstructions, etc." I believe this means they can aim them at any part of the ceiling. Even if that creates a lower trajectory so long as it is aimed at the ceiling. Can you please confirm that so long as it is aimed at any point on the ceiling it is ok, even if that means they are launching at a 45 degree angle (as opposed to a 90 degree angle)? Thank you.Aiming at any point on the ceiling it is acceptable.
 10/18/18 11:17 PMRule 3.c. states glider may be constructed only of wood, foam, paper, plastic film, carbon fiber, tape, thread and/or glue. Can rubber bands be used in the construction and specifically to hold the wing on to the fuselage?No, rubber bands cannot be used as part of the glider.
CollapseEvent Name: Experimental Design
 10/29/18 3:12 PMNational FAQ: Will participants be required to write a "Statement of problem" even though it is not included in the rubric? No. Students may write a Statement of Problem but the Hypothesis will contain information necessary to determine what is happening in the experiment.
CollapseEvent Name: Fossils
 10/29/18 3:09 PMNational FAQ: Will binders be measured using the binding or the rings?Binders will be measured by the size of the rings. A 3" binder has rings that have a 3" diameter on the inside of the rings. The binding of a 3" binder will be larger.
 10/05/18 9:35 AMNational FAQ: Cannot find the Official S.O. Geologic Time Scale. Found a reference in old 2010-11 event that went to a dead GSA site link, so I assume you're using the latest GSA Time Scale (v. 5.0), but that is not the way it's described in the rules.The Official S. O. Geologic Time Scale was modified from the GSA Time Scale and is available on the Science Olympiad website: https://scilympiad.com/data/org/san-diego-so/public/FossilsGeologicTimeScale.pdf The Geologic Time Scale was updated in 2018, but the Science Olympiad Official Time Scale will have 2019 in the title, to reflect use for the 2018-19 season.
CollapseEvent Name: Herpetology
 01/02/19 3:36 PMThe instructions say you can bring a two-inch binder with information from any source, does that mean that a field guide could be modified and then placed into the binder?Yes
 12/05/18 3:28 PMNational FAQ: For Herpetology are the species’ information based on North America only? For example, in population is it for North America or the whole world?Questions relating to species' information will be limited to North American groups and organisms included in the official herpetology list. However there might be a one or two broad, generalized questions about major, exotic groups (populations, examples) elsewhere in the world.
 11/25/18 12:02 PMCan you help clarify if we need to limit ourselves to the exact official herpetology list OR go down even further under those families. Example - for Tortoises, should I limit to just tortoise OR go down to more like Gopher tortoise, Texas or Berlandier tortoise, desert tortoise etc. According to 3.d., participants only need to "be able to do basic identification and answer taxonomy questions to the level indicated on the Official National Herpetology List", but will need to "demonstrate knowledge of anatomy and physiology, reproduction, habitat characteristics, ecology, diet, behavior, conservation, taxonomy, sounds, and biogeography" to levels lower than those indicated on the Official National Herpetology List.
 10/13/18 9:24 AMNational FAQ: "One two-inch or smaller standard binder" should refer specifically to the rings in the binder being two inches or smaller, correct? Yes, the standard for measurements of a binder are based upon the inner size of the rings. For round ring binders, the size is determined by measuring the inside diameter of the ring(s). D-ring and slant-d ring binders are measured by the straight edge of the ring.
CollapseEvent Name: Meteorology
 01/21/19 10:58 AMRecent invitational has questions on Lightning, and characteristics of Ferrel cells. These are only very thinly relevant from the the perspective of topics such as atmospheric circulation and thunderstorms. Otherwise the event rules have no mention of these specifically. What are students expected to do here? Can an appeal be made in such questions or is the expectation that even the thinnest and remotest connected topics be coached and learnt. Aligning with National and Southern California State Science Olympiad, questions of the following type will not be answered: those that are already posted, what materials to use, how to build a device, if a device complies to the rules, what will be covered on a test, how to coach the event, test formats or types of test questions.
 01/15/19 8:28 PMCan students bring coloring materials for the analyzing & interpreting maps and models sections?Yes
 11/13/18 10:58 PMThe rules list only Local winds & Precipitation. Can we take this to mean that student will not be questioned on Global winds and Atmospheric-Ocean interactions?There should not be any questions on global winds. However, although atmospheric-ocean interactions is not a listed topic, questions may still be asked about it in relation to other listed topics.
CollapseEvent Name: Mystery Architecture
 01/27/19 1:17 PMis there a restriction that the parts provided in the bag have to be used whole, in other words without trimming them? of course sticky tape is trimmed to length, but i am referring to things like sticks/straws/paper that are members of the structure? i don't think there is such a restriction (at least from reading the rules) but i had heard that there was some disqualification done regarding this last year. please clarify.Event Supervisors will announce that to the participants after the event has started.
 01/27/19 1:17 PMwhat is the approximate build time? is the overall event duration 50 minutes (when rules are explained, questions are answered, etc.), or is it just the construction time? for example can the construction time itself be just 30 minutes or so? Event Supervisors will announce that to the participants after the event has started.
 01/20/19 12:59 PMin one of trial events in my local area, the event was to build a tower with cups, straws, etc. i was surprised as i know tower was removed from the list this time around and we mostly focused on bridges, cantilever, etc. when asked, i was told that raised bridge is essentially a tower. i don't see how this is the case as a tower is used to raise something and a bridge is used to cross something. maybe i am not being imaginative enough? help me understand, is tower still part of this years competition, albeit in disguise?The devices to be built will be limited to an elevated bridge, cantilever, arch or tunnel.
 12/15/18 8:42 AMFor Arch's primary dimension, if the Arch is built over two pillars, will the height need to be measured from the top of the pillar to the top of the Arch (OR) will the height need to be measured from the bottom of the pillar to the top of the Arch? (OR) is the Arch itself need to be built from the base itself without any pillars at the two ends of Arch.The arch is the part that is curved. The pillars would not be included in the height measurement.
 12/05/18 4:28 PMNational FAQ: For Mystery Architecture, how do you distinguish a tunnel from an arch? Must a tunnel be curved?The tunnel would be a completely enclosed passage leading from point A to point B. The tunnel does not have to be curved. For an arch, it would be a curved symmetrical structure spanning an opening and typically supporting the weight of a mass.
CollapseEvent Name: Potions and Poisons
 01/27/19 10:03 AM"Each team may bring any or all of the items as Recommended Lab Equipment for Division B Chemistry Event." The Recommended lab list includes, Thermometer, 9 vt battery or less conductivity meter and pH or litmus paper. Question: are commercially available battery powered conductivity meter that are powered by less than 9 volts total which also digitally display temperature and pH acceptable equipment for use in the SD San Diego Regionals?No - a digital pH meter is not on the allowed list.
 01/27/19 9:26 AMThe pertinent section states: Each team may bring any or all of the items as Recommended Lab Equiment for Division B Chemistry Events. The aforesaid Lab equipment list recites: "9V or less Battery Conductivity meter." Question: At a recent invitational, in order to perform the Lab Practical sections a digital conductivity meter was required to complete the lab section. My previous experience did not require or use such conductivity meters, e.g., a self constructed one with a 9 vt battery, a red led that glowed, etc., was sufficient. Is a digital output/read out conductivity meter required, as I do not want my team to be at a disadvantage and not have a digital read out? A digital output/read out conductivity meter is allowed as per the list. Teams without it may be put at a disadvantage.
 01/15/19 8:20 AMNational Rules Clarification3.Part I.a.viii. should read: "identification of various poisonous plants and animals, and their toxic effects: ...Wild Carrot (Cicuta douglasii),...". ("Wild Carrot (Daucus carota)" was changed to "Wild Carrot (Cicuta douglasii)")
 10/08/18 8:00 AMCan you clarify the type of "...any needed probes" that may or may not be used and their purposes as noted under the "Event Supervisor will provide..."?For example, the Event Supervisor may ask students to measure the pH of a solution to a higher precision than pH paper is able to determine. In that case, the Event Supervisor will provide the necessary probe(s) needed to get the additional precision.
CollapseEvent Name: Roller Coaster
 01/22/19 7:02 AMHow do you define “next surface” in the rule? For example, When a ball lands on a surface after jumping a gap, can it continue to go up the ramp on the same surface and finally land on “next surface” which is 0.5cm below the elevation of gap landing surface.The "next surface" only refers to the surface immediately below the End of the Gap.
 01/08/19 10:53 AMIs the time taken to level the device counted as part of the 8 minutes?Yes
 12/27/18 1:10 PMAre data/notes required to impound? Do a team need to bring data/note to impound even they are not planned to use them in competition?No.
 11/03/18 11:53 AMIf, for instance, the ball traveling rightward leaves the track and lands on a piece of track angled such that the ball travels leftward upon landing, does this constitute a gap? And, if so, between which two points is the gap measured?No, this would not count as a gap.
 10/29/18 3:31 PMNational FAQ: Please give an example of the added rule: The beginning and the end of each Gap must be at least 0.5 cm above the next surface(s) below them.There has to be a step down to the next 'level' surface below the beginning and end of a gap. There can't just be a line drawn on a continuous surface. The Event Supervisors should be able to take a ruler, place it at the end or beginning of a gap, vertically oriented, and measure a minimum of 0.5 cm from the surface of the track before they hit something below it. (10/25/18 Update: Removed "A drawing will be posted on the website.")
 10/23/18 12:56 PMIn the rules it states prior to the competition, teams design, build, and test a Roller Coaster track to guide a sphere down the track as close as possible to a Targe Time. There is no mention of what that target time is. When will teams be informed of that time so they can design the appropriate Roller Coaster prior to the competition? The Roller Coaster should be designed so that its Run Time can be adjusted during the competition to achieve the Target Time. Please see 4.b. for the Target Time specifications.
 10/18/18 8:17 AMAre there any limits on materials we can use for Roller Coaster B? Please refer to General Rule #1: https://scilympiad.com/san-diego-so/Policy/doc/general-rules
 10/16/18 8:35 AMNational FAQ: Please give an example of the added rule: The beginning and the end of each Gap must be at least 0.5 cm above the next surface(s) below them. There has to be a step down to the next 'level' surface below the beginning and end of a gap. There can't just be a line drawn on a continuous surface. The Event Supervisors should be able to take a ruler, place it at the end or beginning of a gap, vertically oriented, and measure a minimum of 0.5 cm from the surface of the track before they hit something below it. A drawing will be posted on the website.
 09/25/18 8:40 AMNational Rules Clarification2.c. should read: "Participants without eye protection will not compete and will be awarded participation points only."; (removed "ranked in Tier 4" as there is no Tier 4 for 2019)
CollapseEvent Name: Thermodynamics
 01/22/19 7:06 AMWill digital thermometers be used for more precise measurement as compared to a "Liquid-In-Glass Thermometer"? Teams should be prepared for different methods of temperature measurement.
 01/21/19 10:57 AM2nd line, "the best precision of the available instrument", can you provide the precision value of the available instrument which will be used in the regional such as +/- 0.5C, or +/-1C. Aligning with National and Southern California State Science Olympiad, questions of the following type will not be answered: those that are already posted, what materials to use, how to build a device, if a device complies to the rules, what will be covered on a test, how to coach the event, test formats or types of test questions.
 01/14/19 10:48 PMNational Rules Clarification5.c.iii. should read: "Heat Score (HS) = 20 x (the k value closest to zero of all teams) / k, where k is from Newton’s law of cooling: k = - (1 / cooling time) x ln((start water temp - room temp) / (final water temp - room temp))". ("(lowest k of all teams)" was replaced with "(the k value closest to zero of all teams)")
 01/02/19 4:02 PMIn the rules, it states that we are not allowed to use COMMERCIALLY available vacuum sealed devices. However, if the box has been vacuum sealed by the team, not using any previously vacuum sealed parts, will that be permitted. Devices or components that have been built and vacuum sealed by teams are permitted.
 01/02/19 3:48 PMDoes "commercially available thermoses/coolers/vacuum sealed devices" refer only to thermoses, hydroflasks, etc., or does this also include vacuum insulated panels and chambers?Vacuum insulated panels and chambers are vacuum sealed devices.
 01/02/19 3:43 PMCan I use Polyurethane foam (used for Seat Cushion) for device construction? Can I use polyethylene foam (used for packing material) for device construction?Please check rule 3.a. to see what materials are and are not allowed.
CollapseEvent Name: Water Quality
 01/27/19 9:07 PMIn the event rules it specified that the salinometer must be able to function within a 400-600 mL beaker. Does this mean that the water level within the beaker will also be within 400-600 mL, or is it possible it will be less than or greater than this?No less than whatever the capacity of the beaker. The beaker will be filled.
 01/15/19 8:36 PMEach team must build their own salinometer device? During an invitational, we saw teams using commercially purchased salinometers. Is that permissible? Teams must construct their own salinometers and may not use commercially available salinometers.
CollapseEvent Name: Write It Do It
 01/22/19 7:56 AMNational FAQ: is the writer allowed to use phrases such as ‘shaped like a u’ or ‘shaped like a L’? Yes, the writer is allowed to use those phrases as long as the letter they are using does not take on any unique characteristics that would make it a diagram.
 01/15/19 8:31 PMPer the rules, "One participant from each team is shown an object,". Is a 2-D object (or basically a drawing) acceptable as the object for Write It Do It? (A 2-D drawing was recently presented as the object at an Invitational.)Yes, 2D object is acceptable.
 01/02/19 8:40 PMSan Diego Regional ClarificationWriters must stay for the entire writing period (25 minutes), and they will be dismissed once this writing period is over. However, builders must arrive at the start of the event to check in as a team, and they will be required to stay for the entire testing period.
