Awesome Aquifers B

[SirBobo]

How did you demonstrate evapotranspiration?

Good question. Erm, the only thing I can think of is having little lego trees near water.However, actually showing water getting sucked in through the roots and evaporate is going to be kind of hard.

Could i just tell the proctors about the process and say that water will get into the tree and eventually evaporate?

That should work, proctors shouldn't want to see the whole process right before their eyes.

Does anyone know a good way to show remediation without using charcoal? I read on the side of the container that it was known to cause cancer so I guess that wouldbe hazardous. Any other ideas?

There are many many many ways to remediate water. Just think of a material you could add to water that you could easily get rid of through some kind of filter.

If you take a funnel and experiment a little bit, you can generally make a pretty awesome filter. I would suggest using sand, paper towels and some small rocks.

Thanks you guys!!! I ended up using the charcoal, and my topic was contamination and remediations so thank god I took it with me!

Anyone ever heard that the aquifer media have to be "natural" materials like real sand and gravel? We were docked points at regionals for using glass beads as the upper layer because it was "unrealistic". I don't believe there is anything in the rules that limits you to "natural" materials.

That doesn't seem fair at all. Did you have the rule sheet handy?

Unfortunately not, but also did not want to make an issue of it since we finished 1st anyway. Just want to make sure we are good with the glass beads going forward to state.

I'm really not that knowledgeable in this event, however if you look at the official event supervisors guide (http://www.groundwater.org/pe/docs_so/AABeventguide.pdf) on page 19, it indicated that you get penalized for not using the 'correct' materials. Since I don't see glass beads listed as one of the example materials, I'd guess that's where the event supervisor is coming from.

"The list of materials contained in the rules is a suggested list of materials that should allow students to demonstrate all required concepts. With the exception of motorized tools and hazardous chemicals, students may add to the list if they like. Students are not to be penalized if they fail to bring materials on the list; their penalty will come in trying to build models without the correct materials. It is permissible if teams loan each other materials.

Although it says this in the training handout, I'm pretty sure the rules don't say anything about penalties for incorrect material. I recommend you submit an official clarification to soinc.org.



EDIT: The quote was from the section called "Tips for Judging and Scoring".

Thanks for the input. I think an official clarification is the way to go.

Charcoal is only hazardous if you are breathing in large amounts. I am using charcoal as a way of remediation as well, and my coach has told me it is not considered hazardous. Hope this helps
