Very Strange... Last year, I was told that the intent was to standardize the chem equipment so that kids grabbing a crime busters kit would not be penalized for having unauthorized equipment in Potions. This seems to be going in the opposite direction again where 2 separate kits are required.
I attended the Science Olympiad Summer Institute and that is exactly the impression I had gotten from what was being said. The kits are so close, why not just unify them. In addition, I think they could have "trimmed" the list a bit. That's a lot of glassware (as I prefer them working with glass anyway) and not all is really necessary.
I'd hope that the list is "all inclusive" and allow the individual teams to pick and choose which items they feel are critical to have in their kit, and just because it is on the list, doesn't mean it is 'required." I agree that in some cases, certain items that are on the list would not be helpful in Crime Busters... Erlenmeyer flasks as an example... .

Agreed, Dan. I have spoken with our students regarding what they really need and what they can definitely live without. Unfortunately, there are a lot of teams with novice members who will be overwhelmed by that amount of materials. The last time I saw the amount of glassware on that list was when I took my family on a tour of the Pyrex factory complex, on the banks of the Monongahela River in PA!!

I can vouch for this, but I mean we had to use 40 test tubes at nats haha.

But we've NEVER touched our spot plate, petri dish, or microscope slides

I am kinda stressed about this event. Is there an easy way to determine whether the hair is dog/cat/human?

40 test tubes?? Even a "series" of serial dilutions (which should ideally be done in a spot plate, anyhoo!) should not use that many. So why?

The blue dye stained the test tubes and we had to make ~20 mL of a 1:2890 solution. It would've taken forever to rinse and redo everything 5 times.

just find common patterns or aspects of the hairs. for example cat hair has a very distinct medulla, while dog hairs have ovoid bodies, etc. I would recommend looking at different hairs under the microscope, or even searching up pictures of the hairs.

dont be stressed about this event, its actually one of the easier events imo because you dont really have to study or memorize that many things, take advantage of your 5 cheat sheets, put a lot of pictures of hairs if you struggle with them.

I would highly recommend splitting the work between you and your partner based on your strengths and weaknesses so you have time and are more likely to do well. So if one of your team members is really good at identifying fingerprints and you are good at chromatography, each do that task during the competition. Decide which one's you'll be in charge of before the competition!
