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

(section: 2 / line: 1)
Yes, a tablet computer fulfills the same functions as a laptop computer. The only constraint is that like the laptop computer, the tablet must have the ability to turn its internet connection (Wi-Fi, 3G, or other) off for the competition.
(section: 2 / line: 1-2)
No, there is no reason to override this and teams preparing to use a laptop as one or both of their resources will be hampered greatly in competition.
(section: 3 / paragraph: c / line: 2-3)
This is referring to the possible information given about each object, found after the boldface "The Competition", and then sections A and B of the rules following.

(section: 2 / line: 1)
A pocket sized magnifier of any type will be acceptable at the event.
(section: 2 / line: 3)
A published or commercially published field guide is any printed resource that is published and used for identifying natural objects, flora, or fauna.
(section: 3 / paragraph: e / line: 1)
According to the National Audubon Society Field Guide to North American Rocks and Minerals, a recommended resource listed in the SO rules manual, Anthracite Coal is a sedimentary rock. The National Tournament will follow this listing.

(section: 1 / line: 1)
Yes, state and regional even supervisors can make their own list of trees for their competitions as long as the listed is provided to all teams in a timely manner. The local or state list of trees can be substituted for the National Tree List and brought by the students if this is the list being used for the competition.
(section: 2 / line: 3)
A published or commercially published field guide is any printed resource that is published and used for identifying natural objects, flora, or fauna.
(section: 2 / line: 5)
No, This would be a violation of the Spirit of the Rules of the competition. If the tree list is printed on a single side of paper, only the front of the paper may contain notes.
No you are not allowed to make digital modifications to the tree list but you are allowed to write on the tree list.
(section: 3 / paragraph: c / line: unsure)
No, tree identification will be based only upon live or preserved leaf specimens but may be accompanied by other parts of the tree. Twigs, cones, seeds, flowers, bark, fruit, or other parts of the tree may be used without leaf specimens for other types of questions, but will not be used for tree identification without the presence of a live or preserved leaf specimen.
(section: 3 / paragraph: e / sub-paragraph: / line: 5)
Quercus Muehlenbergii is the correct spelling for Chinkapin Oak. This correction has been made to the Official Tree List posted on the National Website. Please be sure you are using this corrected version of the tree list.

(section: 3 / paragraph: c / line: 4)
NO- one device allowed per team.
A purchased multimeter cannot be your entire device, it may be incorporated into the homemade device.
You should expect between 400 and 600 mls of saltwater.
Yes, teams may bring their own containers in which to place the test solution.
(section: 3 / paragraph: c / sub-paragraph: 1 / line: 4-6)
No resolution is stated. This will be determined by the Event Supervisor.

(section: 1 / paragraph: a / line: 1)
Yes. Both sides of the note card can be used for explanation. The text must be legible for the event supervisor.
(section: 2 / paragraph: a / line: 1)
No. The students are not allowed an active website. They work off a CD or off a program on the computer. There should be no active links in the test environment.
(section: 3 / paragraph: a / line: 1)
Use what Jmol designates as the helix. The physical (3D) models that the event supervisors will be using to aid in the scoring will be based on the Jmol designation of the length of the helices.
(section: 3 / paragraph: b / line: 4)
No, there is no specified number, but only 4 will be scored.
(section: e / paragraph: a / line: 2)
The PDB file 1i3o has a mutation at Cys285 in which Alanine was used instead. The cysteine is indeed important to the function and this should be used in the model. The sequence information tells you that Cys should be in that position. The mutation was done to keep the enzyme in a particular conformation for the crystallization process. This information can be found in the primary citation associated with the PDB file.

(section: 2 / paragraph: a / line: 1)
Yes
Templates do not need to be placed in the binder.
(section: 2 / paragraph: a / sub-paragraph: 1 / line: 1)
Yes, students may modify their templates and/or measuring tools in any way during their allowed 4 minutes.
(section: 3 / paragraph: d / sub-paragraph: xii / line: 1)
The barrier (barriers for Div. C) will be placed in the same position for all teams. The chosen position for the barrier will be at the Event Supervisors discretion.
No, teams may not move the barriers. They may place the templates around the barriers or on top of the barriers. Teams may cut their templates to fit during their 4 minute set up time.
It is the line between the laser tip and the target point.
(section: 3 / paragraph: d / sub-paragraph: xv / line: 1)
Yes, mirrors may be placed and left on top of or under the premade template(s)during set up and testing. Putting templates on/in the LSS is not considered modifying it.
Yes, you may use tape to secure the templates.
(section: 4 / paragraph: b / sub-paragraph: iv / line: 2)
The stronger beam will be used for measurement purposes.

(section: 1 / line: 1)
The word “different” refers to the instruments not being alike. The wording “of any type” means the type of either instrument doesn’t matter. Examples of what is not allowed: two flutes, two guitars, two trombones, etc. Examples of what is allowed: a flute and a piccolo, a trumpet and a tuba, a flute and a trombone, a guitar and a ukelele, an xylophone and a drum, etc. While these examples are technically different instruments, they are of similar variety, and students would lose points for "variety". Refer to the scoring rubric when choosing instruments.
(section: 3 / paragraph: b / line: 1)
Parts is all inclusive. Rule 3.b. line 3 only permits strings. Fretwire is not a type of string therefore, commercial fretwire is not allowed.
Yes, all parts of an instrument (other than strings) must be constructed by students.
(section: 3 / paragraph: b / line: 2)
Yes, as long as they are not made from reed material that is commercially sold for use with a musical instrument. If you make a reed out of something other than reed cane, then that would be allowed.
(section: 3 / paragraph: d / line: 1)
Yes, you have 5 minutes to set up.
(section: 4 / paragraph: b / sub-paragraph: ii / line: 1)
In order to get full points in rule 5.i.iii, all music must be played in the allowable range.
(section: 4 / paragraph: c / sub-paragraph: i / line: 1)
In order to get full points in rule 5.i.iii, the chosen duet must be played in the allowable range.

(section: 2 / paragraph: a / line: 1-4)
Yes, as long as their own thermometer or probe is at room temperature, this is legal.
(section: 2 / paragraph: a / line: 2)
Yes, as long as their own thermometer or probe is at room temperature, this is legal. The thermometer/probe may only be used to get an initial starting temperature once the beaker is placed into the device, and must then be removed from the device during the remainder of the testing period. Note that only the temperatures measured with the event supervisor provided thermometers / probes will be utilized for scoring purposes.
(section: 2 / paragraph: c / line: 1)
No, students can bring as many plots at they want in their binders. They can only submit 4 to the judges for scoring purposes.
(section: 3 / paragraph: a / line: 1)
Organic material is matter that has come from a once-living organism, is capable of decay or the product of decay, or is composed of organic compound. Granular material is a conglomeration of discrete solid, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when grains collide). Thus, organic granular material could be described as a collection of pieces of organic material. Some examples of organic granular materials are rice, coffee, corn flakes, sugar, nuts, popcorn, coal, pieces of cork, leaves, etc.
Some dirt can be considered organic however do not assume all dirt is organic. Some dirt and soils contain inorganic materials and would not be allowed. Clay and sand are conglomerations of organic and inorganic materials therefore are not allowed due to their inorganic components.
Cork is not wood but it is organic and must be granular if used. Please see the posted FAQ for organic granular material.
Natural fibers come from plant or animal sources. In their raw form they are typically continuous filaments or discrete elongated pieces. They can be processed into items such as threads, ropes, matted sheets or fabrics. Any of these forms are allowable as long as they are made up of 100% natural fibers. Examples include, but are not limited to cotton balls, wool blankets, and silk fabric.
Yes
No
Yes, it can have printing on it.
(section: 3 / paragraph: a / line: 1-2)
Yes
(section: 3 / paragraph: a / line: 3)
Allowable examples of fastening materials usage include, but are not limited to: Using a single strip of tape or glue along an entire edge to hold 2 sides of the device together (it doesn’t need to be just ‘tacked’ together at a few spots). Spreading a thin layer of adhesive on the entire surface of a piece of aluminum foil to secure it to a piece of wood (e.g. like you would with wallpaper). NOT allowable example uses include, but are not limited to: Using multiple layers of tape on an edge to seal it. Wrapping the entire device in tape to hold it together. Filling a large cavity with glue to ‘hold together’ an inside and outside wall.
(section: 3 / paragraph: a-b / line: 1)
Packing peanuts made from corn starch are a type foam which is prohibited from use in the device per rule 3.b.
(section: 3 / paragraph: d / line: 2)
The entire opening from top of the device to the water surface must be at least 1.5 cm in diameter and remain completely open during the competition.
(section: 4 / paragraph: a / sub-paragraph: iv / line: 2)
Everyone will be placing their exterior/control beaker on a similar surface. Teams are not allowed to use anything different under/around their beaker. Any manipulation of the external control beaker to change the temperature would be a violation of the spirit of the rule.
(section: 4 / paragraph: a / sub-paragraph: iv. / line: 1)
That is up to the individual event supervisor, although the recommendation is that the event supervisor transfers the water. The student(s) load the beaker into their device.
(section: 5 / paragraph: a / sub-paragraph: v / line: 1)
Rule 2.c. clearly states you may turn in up to 4 plots. Rule 5.c.v. awards 1 point per plot for a maximum of 4 points possible.

(section: 3 / paragraph: 1 / line: 2)
The flat disk may be glued.
(section: 3 / paragraph: a / line: 1)
No, teams may not tether their helicopters.
(section: 3 / paragraph: a / line: 2)
The disc is to be parallel to the rotation of the rotors.
(section: 3 / paragraph: a / line: 2,3,4)
No. The balsa wood disc must be the upper most part of the helicopter that would touch a flat ceiling. The disc can be atop a short spike, but the spike cannot be above the disc.
(section: 3 / paragraph: a / sub-paragraph: NA / line: last)
Timing will stop when the disc is dislodged from the helicopter per rule 3.a. The reference to rule 4.j. falls under the last line "or the judges otherwise determine the flight to be over" which would be when the disc dislodges from the helicopter, not when the disc or any other part of the helicopter touches the floor.
(section: 4 / paragraph: a / line: 3)
We will work with the tournament organizers and local building staff to minimize obstructions as much as possible, but cannot make any promises on specifics. Any obstructions that cannot be removed will remain the same for all competitors.
(section: 4 / paragraph: c / line: 2)
Yes
(section: 5 / line: c)
Not necessarily, one motor could run out of turns before the other while still being a rotor and contributing to the overall flight. Dummy rotors that only momentarily contribute lift to attempt the bonus will not be counted, this determination will be left up to the event supervisor on competition day.
(section: 5 / paragraph: c / line: 1)
The axes do not necessarily have to be parallel, but all rotors must be contributing lift to the helicopter (see 3.d, definition of rotors). A horizontal tail rotor (used for yaw control on full-scale helicopters) will not count for the bonus, as it does not provide lift for the helicopter.
It means the radius of the largest rotor.
They will be measured from the minimum separation of the axes of rotation. Thus, if the rotors are tilted away from each other, the measurement will be made from the bottom of the rotation axes.
In order to count as a rotor, it must contribute a non insignificant amount of lift to the flight. This determination will be left up to the event supervisor on competition day, do not attempt to take advantage of the bonus.

(section: 3 / paragraph: b / line: 2)
No, "competitor provided ramp" means that each team must bring their own ramp and compete with their own ramp.
(section: 3 / paragraph: f / line: 1)
Yes, this will count as part of the 10 minute event time and the event supervisor may re-check the paper clip to ensure that it fits within the stated parameters.
(section: 3 / paragraph: g / line: 1)
Rule 3.b. explicitly states the ramp includes the release mechanism, thus is must be within the dimensions too.
(section: 3 / paragraph: h / line: 1)
Teams may use either end of the provided pencil to actuate their vehicle.
(section: 3 / paragraph: k / sub-paragraph: iv. / line: 1)
Yes, many materials could be considered an "electrical" component if included in an electronic device (e.g, rubber used on wheels could also be used to insulate wires), so it is impossible to differentiate between various materials that way. As long as the vehicle uses no electricity, then the materials are legal.
(section: 4 / paragraph: a / line: 1)
Yes, teams may clean the track using their own equipment. This will count as part of their setup time. As long as every team as the same opportunity to clean the track (regardless of whether they take advantage of that opportunity or not,) then the competition is still fair.
(section: 4 / paragraph: b / sub-paragraph: i / line: 2)
The inside edge of the tape of The Start Line refers to the edge closer to the Target Point.
(section: 5 / paragraph: e / line: 2)
No. It is a construction penalty in that a piece fell off and that run should be Tier 3. If however, the vehicle problem can be corrected, the other run would not be Tier 3 based on the piece having fallen off.
(section: 5 / paragraph: h / line: 1)
Yes
(section: 6 / paragraph: f / sub-paragraph: iii / line: 3)
Yes, if a vehicle has a construction violation for one run, that run would be scored in Tier 3. If the other run is not in violation of the rules it is scored in Tier 1.

(section: 3 / line: 1)
Yes, you can use a laptop for the control system, however you must still submit a technical drawing of the control system, the voltage and frequency must be verifiable and satisfy the rules. Use of the laptop for outside communication while competing would be a violation of General Rule #4.
(section: 3 / line: No #)
Yes
(section: 3 / paragraph: c / line: 1)
The spirit of the problem is for students to design and build a device. This does not necessarily mean each component must be modified by the students, but a token modification of a single component from an entire kit would not be within the spirit of the problem either.
Yes, as long as the valve is on the control box.
(section: 3 / paragraph: d / line: 2)
Yes
(section: 3 / paragraph: f / line: 1)
Devices with Bluetooth icons or indicators meet rule 3.f.line 2 as marked with the correct frequency of 2.4 GHz.
(section: 4 / paragraph: a / line: 1)
Yes, but the student is still responsible for understanding these parts used in the device and may be asked to explain parts of the technical documentation.
(section: 4 / paragraph: b / line: 1)
A fastener is intended to hold two or more things together. Its going to take a little judgement on the part of the event supervisor, but the following things are fasteners when used as such: screws, bolts, rivets, washers, straps, nuts, pins, c-clips, e-clips, twist ties, zip ties, straps, rubber bands, belts used as a strap. Rubber bands used to store energy, or a belt used to transfer energy is NOT a fastener. Axle collars if used to retain the axle are a fastener. Bushings and bearings are not fasteners, they don't hold things together, they reduce friction. Gussets are more structural pieces than fasteners. Same is true for standoffs or couplers. In the same vein as event supervisors are expected to use judgements, so should competitors. If you aren't sure, listing it won't hurt anything, for example, it may not be required to list a screw but it won't be penalized.
(section: 6 / line: 1)
No, but the competitors lose the 4 points for identification by default.
(section: 6 / paragraph: a / line: 1)
Yes, but the event supervisor will reset the playing field before competition starts and students may not be touching their devices at that time.
(section: 6 / paragraph: c / line: 1)
Teams will not be ranked in Tier 3 if the time is stopped because of one of the reasons listed in rule 6.c.
(section: 6 / paragraph: c / line: vii)
There are no penalties but timing stops when any part of the arm falls off or becomes detached from the arm.
(section: 6 / paragraph: c / sub-paragraph: vii / line: 1)
NO. The relevant rule 6.c.vii states the time stops when the arm becomes detached from the base. The tool which was part of the arm is still attached to the base, so time continues.
(section: 7 / paragraph: a / line: 3)
The goal boxes do not need to be in the competition area for objects fully supported by them to be scored, assuming all other rules are met (ex. item did not at any time touch the surface outside the playing area, etc).
(section: 7 / paragraph: b / line: 1)
Items resting on two lips of the goal box are counted as "supported by" as long as they are FULLY supported, they can't touch the ground OUTSIDE the goal box.
If the magnet is detached from the arm before the scoreable item is in the goal box, the item will not receive points because time is stopped when the magnet is detached from the arm.
(section: 7 / paragraph: b / line: 2)
Yes, if items are placed in the Bonus Jug while the Bonus Jug is on its side, it will still count. Note that this is different from the rule for the Goal Boxes.
Yes. The rules only state placed in the Goal Box while upright. The placing of the item does not depend on when the item stops moving. There is no problem of the Goal Box going sideways later as long as the item is completely supported by the Goal Box. Teams will lose the 7.f bonus points which state sideways at ANY time.
(section: 7 / paragraph: c / line: 1)
The North Zone would be considered three dimensional. If an object is completely within this three dimensional area, it will receive 1 point if it is not scored otherwise.
(section: 7 / paragraph: d / line: 1-2)
As long as the extra battery is fully in the north zone as otherwise required for that rule, yes, it earns the 1 point.
(section: 7 / paragraph: j / sub-paragraph: i / line: 1)
A motor is a machine that converts energy into mechanical motion. An electromagnet isn't a motor since it only creates a magnetic field.
A pressure vessel may be part of the control box, just as a battery may. It may not be something separate off by itself. The safety of a pressure vessel will be up to the local supervisor to determine as we cannot prejudge a safety decision without physically seeing the device. If there is any question, err on the side of caution.
(section: 7 / paragraph: k / sub-paragraph: iii / line: 1)
This is meant for competition violations above and beyond the specific consequences spelled out in section 6. Events that stop the clock as spelled out in para 6.c are NOT competition violations. Some examples of competition violations that would result in tiering: - A team uses more than 5 minutes to set up their device. - A team receives outside help during the competition period. - Starting to compete without notifying the Supervisor. Blatant unsportsmanlike conduct could result in a DQ.

(section: 3 / paragraph: a / line: 1-2)
Rule 3.a. allows Towers to be placed on the Test Base surface in any configuration as long as the loading chain is suspended within 2.5 cm of the center of the opening in the Test Base. Towers do not have to touch the top surface of the Test Base all four sides of the 20.0cm x 20.0cm.
(section: 3 / paragraph: f / sub-paragraph: i / line: 1)
Yes, it is permissible for the chain to make contact with the Tower during loading if the chain and/or Tower shifts while adding the sand; contact is not a failure mode. However, if the Tower were constructed in a manner which allows some or all of the load to be supported in any manner (vertically or laterally) by the Tower at any point below the loading block, before or during loading; then the Tower must be placed in Tier 2 with a construction violation. The Event Supervisor must decide whether the load or chain has gained any useful support from the Tower by this contact.
