Hello, I'm Jared, back with another experiment on the water cycle.
Love the water cycle, it cleans through evaporation, condensation, precipitation
accumulation. And
we want kids to see that. So we're gonna start with a glass bowl.
And I wanna fill this bowl with anything. I can fill with any liquid: it
could be dirty,
it could be clean, it could be grass,
and that's the cool part, you can experiment. So, I'll just fill this with water.
All it is, is just a little bit water. And I'm gonna add some food coloring to it so
you can see. This could be cool-aid, this could be grape juice, this could be soda,
you could throw in applesauce, and check that. Anything with moisture in it
that can evaporate is cool. Let's put in some salt,
and I have my little mixture. And what I want to do is actually try and
create a solar still. So I have a little glass container that's going to
sit in the center, and all I want to do now is cover this, seal this. I have a
piece of plastic
I'm gonna put over the bowl.
Make sure its sealed. If you wanna run a piece a tape around the edge you can.
And now what I need to do
is, I need a weight. A piece of rock would work. I have just a little metal bearing. It's
gonna go in center.
And now I'm ready to put it outside and let it cook
and see the water cycle happen. What's a great thing about this is you can guess,
hypothesize what's going to happen as that sun
heats up. What do you think's gonna happen? Is blue water gonna end up in that little
cup?
Is it gonna taste salty? if I fill it with soda,
am I gonna have a cup of soda? I don't know, but that's cool thing about science.
You get a run the experiment and see the results happen.
Let's see what happens after it cooks.
