That's not how science olympiad works. The community isnt at your beck and call. There's a ton of information in this thread, if you'd go back to the beginning and read it, but remember, YOU'RE responsible for your own success or failure. We're here to offer some advice, but ultimately, you're the one that needs to find as much information as you can and know how to apply it.

that's very true. WE don't have to help you, but we choose to be nice and generous. so don't take our generosity for granted and we will try to help you

thanx for the help, rocketman, the wiki was very helpful.

To everyone who quoted my post: i was just asking for some help, not taking your advice for granted

[sciolympian]

my replies to other posts:
to Rocketman1555: thanx, rocketman you're da best. the wiki link rox.
to sciolyandmathcounts: you were a big help too. the advice you gave me was excellent.

Hey does anybody have any idea on how many observations you should have? Like is there a good ammount that you should have? Sorry if this is a bad question I've just been wondering because it seems like whenever I take the test I never seem to have enough... Anyways if anyone knows and replies thank you for your insight!

Good Tests(in my opinion):
PH
Acidity
Temperature
Endothermic/Exothermic
Carbonate?
Electrolyte?
Color of Agent? etc.

sciolyandmathcounts had some good tests for observations

How do you use the tester to test to conductivity?

[sciolygrl258]

Put the metal probes into the liquid and if it has a high beep it is high ionic, if it has a low beep it's low ionic, if it doesnt beep then it covalent.

Well, that depends on the type of tester you have. We are getting a digital one, and it gives us qualitative data.
