science for tinies: snow, part I
Jan. 27th, 2011 10:49 pmProject: What Is Snow? Part I
Materials: snow, clear jar or pitcher, scoop
Explanatory details: Junie filled the jar with snow while I shoveled, then we brought it in and left it on the counter.
How did it go: Ok. The concept of "let's leave this for awhile and check back later and see what happens" was less exciting than "let's get instant results", but a lot of science is like that, so, enh, realism. (Don't even get me started on the avocado pit, which I put in water on Monday and is apparently supposed to sprout roots in March.)
Things we talked about: Snow is made out of water, and when it gets warm, it melts into water.
What Junie got out of it: I got her to make the identification of what was sloshing in the bottom of the jar as water. Of course then she was like, "a container! with water in it! aha, let me get the rock and the duck!" But this actually led to her making the independent observation that when she put the rock down on top of the lump of snow remaining in the jar, "rock sits on there", which I *think* might have been her noticing that the rock did not sink in the snow the way it sank in water, even though we were just talking about how the snow was water? I don't know, I may be reaching here. Anyways, I told her snow was solid water and solids don't let things sink through them the way liquids do, and she was like, yeah, yeah, look, the rock is wet now. ::shrugs::
Once the snow had melted all the way, we put it back outside to see if it would turn back into snow when it went back outside. We'll look tomorrow and post our results!
