Division B Events

Reveal Questions

Questions must be directed toward the rules. We cannot pre-judge your device by answering questions on whether it complies.

Earth & Space Science
- Dynamic Planet - Div B
  - (Section: 3 / Paragraph: x / Line: 1)
    
    12/31/2019
    
    Line x. says Division C only: etc....Is that only applicable to Line x or does that apply to Line x. and everything after it/below it?
    
    Division C Only refers to just "x". All subsequent sub-paragraphs are for both Div. B & Div. C.
- Fossils - Div B
  - (Section: 2 / Paragraph: a / Line: 1)
    
    10/29/2019
    
    Shouldn't Limestone on the Fossils List read "Limestone (chalk/fossiliferous limestone)" instead of "Limestone (chalk/fossil limestone)" (which fits with how Rocks and Minerals names it)?
    
    "Limestone (chalk/fossil limestone)" is equally acceptable to "Limestone (chalk/fossiliferous limestone)". Either term may be used.
- Meteorology
- Reach for the Stars
  - (Section: B40 / Paragraph: a / Sub-Paragraph: 2a / Line: 7)
    
    10/24/2019
    
    Are pictures and illustrations allowed on the 2 sheets of notes in Reach for the Stars and can we ID them? We don't know what no labels means.
    
    Yes, pictures and illustrations are allowed and can be captioned or labelled. What is not permitted is the addition of anything to the surface of the sheet, such as but not limited to adhesive labels, tags, stickers, or Post-It Notes, which add surface area and space to the sheet of paper.
- Road Scholar
Inquiry & Nature of Science
- Experimental Design - Div B
  - (Section: 4 / Paragraph: a / Line: 1)
    
    10/10/2019
    
    In the checklist section H, do the raw and condensed data tables need to be distinct, with the "raw table" containing measurements and the "condensed table" containing derived values?
    
    Yes, the raw and condensed data tables are two separate tables.
  - (Section: 4 / Paragraph: a / Line: 1)
    
    01/05/2020
    
    On the Experimental Design Checklist does Statistics Claim refer to claiming what the statistics are, or what you are deducing from the statistics, or choosing which statistics to base your trend and interpretation of the data?
    
    A claim is an assertion of the truth of something, typically one that is disputed or in doubt. You will then provide evidence, in this case statistics, that back up your claim. In the reasoning section, you will explain how the statistics back up your claim.
  - (Section: G. / Line: 1)
    
    01/03/2020
    
    On the top of the table, what is meant by "Before" and "After" for Procedure and Results?
    
    As for your question about the meaning of “Before” and “After” on the Experimental Design Report Form this section is looking for participants to make observations about their procedure and approach to the experiment (e.g.; spills, limitations on measurements/accuracy, compromises for efficiency) and then make observations about the results they obtained (e.g.; trends in the data, relationships between variables/constant). The blank space asking for a results observation Before conducting the actual experiment is an error. New a form that clearly show the box shouldn’t have any information is posted on the Event Page at soinc.org.
- Game On
  - (Section: 5 / Line: 2)
    
    10/29/2019
    
    For this year will there be different point ranges given for particular types of games, is it expected to make combination game types for higher score?
    
    No, there is no requirement of game type in this year’s rules.
- Ping-Pong Parachute
  - (Section: 2 / Paragraph: B / Line: 1)
    
    11/08/2019
    
    "Parachutes must be attached to ping pong balls with tape only." Can a team tape a ping pong ball to string and tape the string to the parachute?
    
    Yes, this does not violate the rules as stated in rule 2b. The strings that are attached to the canopy are called shroud lines and they are part of the parachute. The shroud lines may be taped to the ping pong ball.
  - (Section: 5 / Paragraph: e, f / Line: 1)
    
    10/23/2019
    
    Can other parts separate from the rocket other than the parachute payload system? For instance, can a cone covering the parachute land off to the side separated from the rocket and payload system and not be tiered?
    
    Yes. Parts separating from the rocket/payload assembly will not cause the rocket to be "tiered." The parachute / ping pong flight time is what accounts for the score. No part of the rocket / parachute assembly can come in contact with the ceiling.
  - (Section: 2 / Line: 1)
    
    01/08/2020
    
    Does anyone know this? To practice at school: Is it possible/safe to use a bottle rocket launcher that has been used in previous years--when the rockets contained water?
    
    Yes, it is possible to use launchers from previous years as long as the launcher has been inspected and determined to be safe by your coach/adult supervisor. You should also make sure that the launcher will launch rockets that fit the construction parameters. Depending on the launch pad you have you will need to insure that it does not damage the floor when being used.
  - (Section: 2 / Paragraph: B / Line: 1)
    
    10/10/2019
    
    Is glue allowed on the actual parachute itself? In other words, as long as the only thing directly holding the parachute to the ping pong ball is tape, is it legal?
    
    Yes, glue is allowed on the parachute. It is not allowed on the pressurized bottle.
  - (Section: 3 / Paragraph: c / Line: 1)
    
    10/24/2019
    
    Is the nose required to fit partway into a bottle cap?
    
    No, the nose of the rocket is not allowed to be able to touch the inside top of the cap. It is not required to fit partway into the cap.
  - (Section: 2 / Paragraph: a / Line: 1)
    
    10/29/2019
    
    May multiple parachutes be combined into a single parachute payload system and attached to a single ping pong ball?
    
    Yes. Multiple parachute systems can be used as long as they are attached to the ping pong ball. The parachute(s) ping pong ballflight time is what accounts for the score.
  - (Section: 3 / Paragraph: C / Line: 1)
    
    01/08/2020
    
    What classifies as a blunt or rounded top?
    
    Blunt and rounded are two separate issues. If the nose of the rocket comes to a point, the point must be rounded so that it fulfills the requirements of rule 3.c. This is specifically shown in Figure 1 in the rules. If the nose of the rocket is not pointed, the leading edge of the rocket must be blunt. Blunt means that the edge must not be sharp and still fulfill the requirements of rule 3.c. No part of the edge can fit into bottle cap as defined in rule 3.c.
  - (Section: 2 / Paragraph: a / Line: 1)
    
    10/23/2019
    
    What qualifies as a parachute?
    
    This is the definition of a parachute we will be using: parachute - a device for slowing the descent of an object through the air that consists of a canopy beneath which the object is suspended
  - (Section: 2 / Line: 1)
    
    10/09/2019
    
    What's the maximum psi?
    
    Please see the posted Rules Clarification which says that at no time should the pressure vessel (bottle) be pressurized beyond 65 psi. ~~Due to the variation in the sites where the ping pong parachutes will be held, there can not be one max psi that is published.~~ Teams will be placed in Tier 3 per rule 5.g. if any part of their rocket or parachute hits the ceiling or any part connected to the ceiling.

    Yes
  - (Section: 2 / Line: 2)
    
    10/08/2019
    
    Under Order Strigiformes, the screech owl is listed, but I believe that is a genus that doesn't pertain to a singular species. Should this be specified to a certain species (Eastern screech owl), or should this remain as a genus?
    
    Remain as a genus and be familiar with species within the Genus.
  - (Section: List / Line: 40)
    
    10/29/2019
    
    Under the list, it says “Clapper rail” with the scientific name of Rallus Longirostris. However, Rallus Longirostris is actually the Mangrove rail, which is not in the rules. Which one should participants study?
    
    Use the taxonomy as listed on the Official National Bird List.
  - (Section: 2 / Paragraph: c / Line: 2)
    
    10/08/2019
    
    Will a separate National Ornithology list that is annotated be allowed to be taken out of the binder?
    
    No, an annotated Bird List must remain in the binder if the event is run as a series of stations per rules 2.b. and 2.c.
- Water Quality - Div B
  - (Section: 3 / Paragraph: b / Sub-Paragraph: i= / Line: 1)
    
    11/24/2019
    
    Are participants expected to differentiate between multiple species of the same organism?
    
    No, the students will just need to recognize all variations as a particular species.
  - (Section: 2 / Paragraph: 1 / Line: 3)
    
    10/08/2019
    
    Could you please clarify the meaning of, "from any source without any annotations or labels affixed". Can they have diagrams that are pre-labeled?
    
    Students may make a word document in which they put in notes, diagrams etc. which can be pre-labeled and print it onto a page double sided or they may hand-write the notes, diagrams etc., but they may not add anything additional to the sheet of paper such as labels, adhesive flags, sticky notes, or anything extra to the surface of your reference sheet.

      Can skinny jeans be a universal exception to the "loose-fitting" pants rule for chemistry events?
      
      From the rules: Pants should be loose fitting; if the host has more specific guidelines they will notify teams in advance of the tournament. In chemistry events, any tight-fitting pants do not provide the loose-fitting safety margin necessary should a hazardous chemical be spilled on the clothing to prevent the skin from sustaining a chemical burn.
    - (Section: 2 / Paragraph: B / Line: 1)
      
      10/08/2019
      
      For both the Chemistry events, the rules say “each participant may bring one 8.5” by 11” sheet of paper.” Does this mean each team is allowed two pieces of paper, or does “participant” mean team?
      
      If a team has two participants in these events it is allowed two reference sheets; one for each participant. If for some reason the team only has a single participant in the event then that team is allowed a single reference sheet for that participant. If two sheets are used the content does not have to be exactly the same on both sheets.

      10/29/2019
      
      For the nutrition labeling regulations, are the questions supposed to be about the nutrition label of fermented food types only or all food types?
      
      Students should be able to read any food label and answer questions about the information on the label.
    - (Section: 3 / Paragraph: a / Sub-Paragraph: ii / Line: 1)
      
      10/09/2019
      
      I do not know how to find the % moisture in a pickle without using dehydration & volume (before and after) or through commercial equipment. How are students supposed to be able to do this?
      
      There are multiple methods that will allow the approximate percent moisture of a pickle to be determine. Complete dehydration is one. An approximation of the percent moisture can be determined by massing the pickle in a container then doing something to the pickle (i.e., crushing it) to release the moisture. The moisture released can then be removed and the pickle remnants and container can be remassed.

      11/24/2019
      
      Is the salinometer required to be mechanical? Can it be electrical or electronic, as long as it is built and can be explained by the team?
      
      Yes, it can be electrical.
    - (Section: 3 / Paragraph: b / Sub-Paragraph: 1 / Line: 2)
      
      10/24/2019
      
      It states in the rules that "to operate within a standard 500 mL beaker...," however 500 mL is not a standard Griffith beaker size. Should this read 400 - 600 mL?
      
      Yes, a beaker size between 400-600 ml is fine.
    - (Section: 3 / Paragraph: a / Sub-Paragraph: xi / Line: 1)
      
      10/09/2019
      
      There are quite a few yeast and bacteria out there. Can we get a list of which ones the students will need to know?
      
      These are common examples but event supervisors may use bacteria or yeasts that are regionally appropriate. Yeast-fungus-the most common type used in fermenting is Saccharomyces cerevisiae - Can grow aerobically or anaerobically on sugars - Most commonly used for production of ethanol in fermentation Lactic Acid Bacteria (LAB) Lactobacillus, Homolactic-used for making Yogurt, souring vegetables, making sausage Leuconostoc, Heterolactic-used to sour vegetables Streptococcus, thermophiles, Homolactic-used for making Yogurt Acetobactor, Acetic Acid Bacteria -used in the production of chocolate & wine. Bacilus, spp., spore producing bacteria – used in the production of chocolate.

      11/08/2019
      
      Rules specify maximum beam lengths of 80.0 cm (B) and 40.0 cm (C). What is the definition of Beam Length?
      
      The “length of the beam” is the physical length of the single beam, including any permanently affixed non-movable fixtures extending off the physical end of the beam. If either attachment point (or the fulcrum) extends beyond the physical end of the beam, the distance between the attachment point (or the fulcrum) and the end of the beam is included in the “length of the beam”.

      11/08/2019
      
      What is the desired format for the mass ratios?
      
      That will be up to the individual event supervisor to specify. Any equivalent format (decimal, fraction, table format) will be accepted. However, fractions must not be complex fractions (i.e. having a decimal or fraction in the numerator or denominator). Note the official scoresheet expects it to be entered as a decimal value, but the supervisor can easily convert a fraction to a decimal if they desire.

    The wall or base may be considered as part of the "tee holder" and would not be subject to the 10cm clearance requirement. However, the top of the tee must still be at least 2.5 cm above any part of the "tee holder".

    Is there a maximum Chord length/wing span and/or wing area for the fore wing/horizontal stablizer?
    
    No, but as stated in para 3.j, the horizontal stabilizer must be in front of and smaller than the main wing to meet the canard bonus. Span and chord both. There is specifically no limit on the horizontal stabilizer this year, be it behind the main wing, or in front to meet the criteria for the canard bonus. The largest horizontal surface will be considered the wing. As already stated, largest by BOTH span and chord. The next largest horizontal surface will be considered the horizontal stabilizer. There should be no significant third horizontal surface. Fuselage, so long as it does not contribute significant lifting surface will be disregarded.
