Bottle Rocket

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

2015-11-12 13:07 Is putting light pen marks or lines on the pressure vessel bottle considered physical, thermal, or chemical damage?

Writing on the bottle would not be physical damage unless the person doing the writing did something out of the ordinary which damages the structural integrity of the pressure vessel.

Invasive Species - Div B

(section: 2 / paragraph: 1 / line: 4)

2015-11-12 14:05 My question is about the official national list of invasive species. Under vids, it lists Bird Flu, H5N5. Does this mean only H5N5, or could it include other strains of bird flu? I.e., should the kids really only be researching H5N5?

Yes, H5N5 is the only Bird Flu on the National Official List. Check with your State or Regional Director if they will be using a different list.

Food Science

(section: 2 / paragraph: a / line: 5)

2015-11-12 13:27 May students bring pipettes to measure the drops of lemon juice/vinegar? The rules do not specifically require event supervisors to provide them and if the student's prior research was measured using drops, they will need them.

No, the students can not bring pipettes. The event supervisor may provide them, but the students should not plan on that.

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

2015-11-12 13:29 Can students bring something to "fasten" the cheesecloth over the beaker such as a rubber band or will that be provided by the event supervisor?

Students may only bring what is listed in the rules. All other materials should be provided by the event supervisor.

(section: 3 / paragraph: b / sub-paragraph: iii / line: 4)

2015-11-12 13:57 The rule says using heavy cream. We only found heavy whipping cream in supermarkets. Can we use heavy whipping cream for our experiments?

Yes, Heavy Cream and Heavy whipping cream are similar differing with the percentage of fat. Heavy cream is about 36% and heavy whipping cream is about 30% milk fat. The students should practice with different types of cream because you don't know what type of cream the event supervisor will provide for this Lab.

Wind Power - Div B

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

2015-11-12 14:33 Is the CD that the blades are mounted to only held on to the generator by the detent balls on a CD player or can extra support be provided such as double sided adhesive tape to strengthen the joint?

Yes, as long as the tape is easily removable and does not impact other subsequent teams' testing.

(section: 4 / paragraph: l / sub-paragraph: ii / line: 1)

2015-11-12 14:35 Rules state that "Power generator general questions...."Does this refer to the general question of how electrical power is generated in each of these types of power plants or specifically to the generator itself?

Anything related to power generators in general is a valid question, which could include aspects of the power plants.

Air Trajectory

(section: 3. / paragraph: f / line: 1)

2015-11-12 13:04 Team must provide unmodified light weight plastic or foam golf balls to be used as projectiles. Are practice plastic golf ball with holes on the side consider "Unmodified"?

Yes, plastic golf balls purchased with holes in them are considered unmodified and are allowed.


Mission Possible

(section: 4 / paragraph: c / line: 1)

2015-11-12 14:25 Can there be a release of stored energy between the two simple machines in a transfer or does the output of the first simple machine have to directly drive the input of next one?

Yes, there can be a release of stored energy between the two simple machines in a transfer. No, the output of the first simple machine does not have to directly drive the input of next one.

2015-11-12 14:26 Can the second simple machine in a transfer be the first simple machine in the next transfer?



Bridge Building

(section: 3 / paragraph: e / sub-paragraph: N/A / line: N/A)

2015-10-29 13:14 Does this mean that the loading block shall be aligned with the centerline of the test base, or is it acceptable for the loading block location to be off to one side as long as it allows for the chain pass through the 20cmx20cm opening of the test?

The loading block is to be aligned with the centerline of the test base which would be the center of the Bridge span when it is placed on the Test Support on one side and the Bearing Zone of the Test Base on the other side.

(section: 4 / paragraph: c / sub-paragraph: i / line: 1)

2015-10-29 13:24 Will the 5 by 5 block be secured to the testing apparatus?

No, the 2 cm x 5 cm x 5 cm block will not be secured to the Test Base.

(section: 5 / paragraph: b / sub-paragraph: i / line: 1)

2015-10-12 19:36 If the bridge is loaded not to failure of the bridge, but rather the test support falls over, how will the bridge be scored (will there be a second try) ?

If the test support falls over, loading will stop and the weight held at that time will be used to calculate the final score. There will not be a second try at testing the bridge.

Elastic Launched Glider

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

2015-11-12 15:04 The rules state that "The functional components MAY be attached to each other using tape, thread or glue. However could the wing or horizontal stabilizer be attached to the fuselage stick by way of a rubber band?

No, rubber bands are specifically not allowed to attach the wing or stabilizer to the fuselage for safety. The wing or stabilizer could become separated from the fuselage during launch.
