According to what was done at the Summer Camp, there will be an identification portion to the event. Still not sure whether or not there is a salinometer.

Here are the rules for the 2006 version of the event.
ornithology, forestry, entomology, triple E, green generation, water quality, dynamic planet (lakes & rivers), awesome aquifers, meteorology, robot arm, write it do it. :)

A cone of depression occurs when you drop your scoop of ice cream on the ground on a hot summer day.

The last known rules don't allow for any resources besides a non-programmable calculator - however, that is how ecology started, and eventually a notesheet was allowed. I wonder how they will do it this year.

the questions (from really old practice tests) seem relatively easy, basic chem knowledge. the ID (if it's gonna be there) might be the hardest part. and judging from the NY state schedule, it's a sign-up event so there probably will be a build/lab involved.

The lab will probably be 1) the Salinometer being tested and 2) actual testing of water quality (using hydrometers, Secchi discs, TDS meters, ph paper, etc)

Where would be a good start for making a Salinometer?

I heard, in the beginning, that a lightbulb system might work. The only issue is, it's probably not sensitive enough...
It's so easy, even a Badger could do it.

Does anybody know why we have to wear goggles in WQ?

Probably safety precautions - we will probably deal with a lot of water. Don't want that in your eyes!

I could understand goggles if it was testing powders.. But if it is only testing salt in water, that seems interesting..

There are a lot of differing opinions on the rules committee about goggle usage, and as a result, we are a little inconsistent, but do tend to err on the side of safety. This event isn't in my committee, so I don't know what discussion if any went into this, but my guess is there is concern the the team-built hydrometers might have various chemicals / components that pose a potential eye danger.
