[00:00:11.861]Alright guys, so what do you have
[00:00:13.660]in your jars right now?
[00:00:15.990]Sand.
[00:00:16.823]Sand. All right, next,
[00:00:18.280]we're going to put a little water
[00:00:21.650]in each of your cups so that our sand gets wet.
[00:00:24.940]Can you add a little bit of water?
[00:00:27.260]Uh-huh.
[00:00:28.168]The water is in this cup.
[00:00:29.150]Can you add a little water?
[00:00:32.277]I can't.
[00:00:33.620]I help.
[00:00:35.788]Like that?
[00:00:36.621]Exactly, yes.
[00:00:38.635]Do we put it in now?
[00:00:39.468]Here you go.
[00:00:40.370]Go ahead and pour that into your sand
[00:00:41.980]to make it a little wet.
[00:00:45.690]All of it?
[00:00:46.530]Yes.
[00:00:50.440]We're gonna make our sand damp.
[00:00:53.440]Very good. Now let's wait a little bit.
[00:00:56.450]More? No, that's enough.
[00:00:58.380]We just needed enough to make our sand a little damp.
[00:01:02.670]Next, while that is soaking into our sand,
[00:01:06.430]I want you to take this ball of clay
[00:01:08.630]and I want you to flatten it into a flat circle.
[00:01:12.610]Can you put that right over here?
[00:01:14.320]And can you flatten it into
[00:01:19.169]a flat pancake?
[00:01:21.390]Flat, flat, flat.
[00:01:23.490]Just like this?
[00:01:24.323]Yes, maybe a little bit more.
[00:01:25.540]Can you try to flatten it a little bit more?
[00:01:30.919]This? About this?
[00:01:32.984]All right now what we're going to do,
[00:01:34.542]Very good. Very good.
[00:01:36.150]Now what I want you to do is you're gonna place that clay
[00:01:39.370]into your jar.
[00:01:41.660]Just like this?
[00:01:42.830]Yes, and we're gonna cover half of our sand
[00:01:45.410]with that clay.
[00:01:47.455]Like this?
[00:01:49.950]Yes. Yes.
[00:01:52.120]Very good. Perfect.
[00:01:53.950]We'll probably,
[00:01:55.560]yep, move that over a little bit.
[00:01:57.720]All right. So, Lily, very good.
[00:02:00.371](indistinct whispering)
[00:02:04.190]Now we are going to place the gravel on top of the clay
[00:02:08.820]and have it slope to one side.
[00:02:11.430]It's the rocks.
[00:02:12.710]So we're gonna go ahead,
[00:02:13.543]use your little cups that you used for the water
[00:02:16.470]and scoop a little gravel out of there.
[00:02:18.961](gravel rattling)
[00:02:20.320]Go ahead and pour that on top of your clay.
[00:02:26.300]That'll work. That's enough.
[00:02:27.540]Garrison.
[00:02:29.800]You go ahead and get a little gravel
[00:02:32.720]and pour
[00:02:34.520]on top of your clay.
[00:02:37.381](gravel rattling)
[00:02:46.691]You add a little bit more?
[00:02:49.600]Go ahead and get a little bit more out of the cup.
[00:02:53.173](small child sings) (Sarah hushes child)
[00:03:00.047](gravel rattling)
[00:03:02.950]Alright, now what I'm going to do is add the pollution.
[00:03:05.990]The pollution is going to be our food coloring.
[00:03:10.690]So I am going to place the food coloring,
[00:03:14.060]or our pollution that pollutes our water,
[00:03:18.700]right on top of the gravel.
[00:03:23.120]And we're going to watch it spread throughout our aquifer.
[00:03:33.740]Okay, watch the pollution.
[00:03:36.709]Okay.
[00:03:43.947]Now can we put the lid back on?
[00:03:46.530]You can put the lid back on.
[00:03:49.509]It smells yummy.
[00:03:51.077]Put the lid on.
[00:03:52.696]Do we shake it?
[00:03:53.529]Nope.
[00:03:54.533]You're gonna set it, watch it there,
[00:03:56.065]and watch it
[00:03:57.460]as the pollution, watch how it goes through the layers
[00:04:02.560]of our
[00:04:05.510]different types of
[00:04:07.690]Cup.
[00:04:09.970]Turn that back around Lily.
[00:04:12.482]Alright.
[00:04:13.315]So that the video can see it.
[00:04:15.020]There you go watch that red, which represents our pollution.
[00:04:20.740]Now explain
[00:04:21.786]A bit more, Dad?
[00:04:23.910]Explain to me,
[00:04:26.890]A bit more, Mom. Lily, what do you see?
[00:04:29.431]I see red rocks in there.
[00:04:32.900]I see red rocks in there.
[00:04:35.540]Do you see that red pollution
[00:04:38.360]going anywhere else?
[00:04:39.691]Can I have a little bit more rocks, Mom?
[00:04:44.065]No.
[00:04:54.778]A little bit more.
[00:04:57.783]Okay, we're done.
[00:04:59.835]Yay!
