Anybody thinks there'll be changes to the rules this year?

[sciolygrl258]

I don't think so, there's not much to change. The rules are pretty simple.

[melody2k6]

Well, they might add NaOH to the rules this year or some other reagent.

[rocketman1555]

NaOH was in the rules last year.

[melody2k6]

Was it? They had it at Nationals but I don't think it was in the official rules.

[rocketman1555]

You're right, it wasn't in the rules last year. I was looking at an old test.

[melody2k6]

I've always been wondering about this, but are you suppose to make an inference in an observation? Some sources say that in order to get a 5 point observation, you have to make an inference. Is this true?

[haven chuck]

Absolutely not. It may mean that in order to answer the question (and get the full 5 points), you have to make an inference from your observation, but a good test/test grader would never dock points because you made an observation and not an inference. The [wiki]Can't Judge A Powder[/wiki] has a good section on writing proper observations if you need more clarification on what is and isn't allowed.

This may sound redundant, but that event supervisor from nationals was a super-d****e. She disqualified a person (I forgot your username, sorry!) for rubbing their eye inside their goggles! Most people aren't perfect! We might forget stuff even if it's Nationals and extremely important.
