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

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

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

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

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

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?

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. :? :x :roll:
