Normal plastic drink bottles ( water or soda) are between 500 and 600 ml. This is why that range was chosen. It will be up to the event supervisor to determine how close to that range they will accept. Teams should be prepared to stay within that range.
(section: 2 / paragraph: a / line: 4-5)
The requirement is that the container be 500-600 ml. There is no requirement that the container have a manufacturer label to that effect.

No, the students can not bring pipettes. The event supervisor may provide them, but the students should not plan on that.
(section: 2 / paragraph: b / line: 2)
Yes, students may bring a timer.

All test questions should be related to dairy food science.
(section: 3 / paragraph: a / line: - )
Pictures are preferred. But accurate drawings are allowed.
(section: 3 / paragraph: A / line: 2)
The experiments may be typed and placed in the Notebook.
(section: 3 / paragraph: a / line: 2, 3)
The Food Science Experiment Form may be expanded to include all that is required to be documented for each experiment.
(section: 3 / paragraph: a / line: 5)
Each Experiment will have one Independent Variable that must be tested at 2 or more Levels (examples of Levels would be different Levels of milk fat, different quantities of the Independent Variable; different length of time mixing or shaking; different types of acid; etc.). These Levels do not need to be repeated in multiple Trials but can be and should be included on the same Experiment Template. According to the rules there is no expectation of multiple Trials so there will not be penalties or bonuses for the lack of multiple Trials or inclusion of multiple Trials. Each Task (Curds, Butter, or Ice Cream) requires a minimum of 3 different experiments. Each of these different experiments must have different Independent Variables or they should be counted as duplications and receive no credit.

10 points is the maximum number of points. The masses will be confirmed by the event supervisor and points awarded based on their measurements. If the students mass > ES mass, the team will score 10 points.
(section: 3 / paragraph: b / sub-paragraph: ii / line: 3)
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: ii / line: 4)
Yes, they should be dry. Please see the training guide posted on the National Website under Food Science.
(section: 3 / paragraph: b / sub-paragraph: iii / line: 4)
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.
(section: 4 / paragraph: a,b,c / line: 1)
The written test may be given during the entire time period so the students may work on it during the experiment portion. This is up to the event supervisor.
(section: 3 / paragraph: b / sub-paragraph: iii / line: 5)
For crime busters, the only burn tests allowed in the event are on the fibers. If the results of burn tests on the plastics are important, the event supervisor must divulge the results of the competitors in the crime scene scenario.
