Thanks. I have another question though, wouldn't you have to take out the previous aquifer?

Why would you need to do that?

well, i guess you wouldn'nt really, i was just thinking a different way, but you could explain it all in one aquifer, i just never really thought about it... thanks for explaining :)

No problem, good luck at your competition!

I just explained the concepts using an extensive knowledge of the vocab words to impress the judge and managed 4th place at NY States even though the model that we built was nothing but a layer of sand, gravel, and a piece of clay thrown in somewhere. To show confidence in the model and in your presentation skills really impress the judges.

Does anyone else think that the States test for Awesome Aquifers was too easy and ridiculous?
Congrats on fourth! Is there any reason why you used sand instead of gravel for one of the layers? We tried using sand, but it was difficult to see the location of the water table.

Stations 1 and 2... left much to be desired. There wasn't any actual diagram interpretation, and everything but the last question was multiple choice. I liked the concepts chosen for station 4, but there could've been a few more difficult ones thrown into the mix to create a wider gap between scores. I'm sure 1st place and 6th place were only separated by a few points.
Good job on 2nd! We hadn't really prepared and our model was a fail but we had really brought it together with the presentation because we pretended to show confidence. Sand was just what we brought and we used a very thin layer of sand, about a fourth to a half of an inch thick. We made the water table higher than the sand since we were able to see the water table when it was at the gravel thanks to the porosity of the gravel.

For some reason, we cannot show a cone of depression concept (for states) because the pressure in our aquifer is to low. Can anyone tell me how they are doing it.

I don't know if this will help you, but we had the same problem until my partner got a huge soap pump from our tech teacher.

Here it is in all its glory. =D For those who are wondering, we were experimenting with Go stones for the top layer, and the colorful foam below the Monopoly houses was supposed to represent sinkholes.

Thanks FueL, that really helps. I can't tell from the picture, but is that a confined aquifer or an unconfined :?:

Me and my partner will try a larger hand pump, though.

The blue thing is a clay layer but it doesn't stretch all the way across, so there's both a confined and unconfined aquifer. The soap pump is drawing water from the confined aquifer.

I see.
