I had NO IDEA!!! I don't why this surprised me so much. Even in space there is air, is it just composed differently.
In Dr. Cuccio's Teaching Elementary Science class, we did this Science demonstration where Casey was placed inside a heavy duty trash bag. Dr. Cuccio then placed the hose of the vacume cleaner and sucked all of the air out of the bag until it was tightly formed around Casey's body (Picture 1).

I am still not 100% positive on what all this demonstration was exactly showing. I was at a family lunch today and was telling everyone about it. Amanda, my future **whitty and smart** cousin-in-law asked "well, if there is no air in the vacume, whats in it?" and I was stumped. I honestly don't know. Which got me thinking, it is not the vacume in itself that is the object without air- rather the result of the vacume on a certain type of subject matter (body inside of a trash bag). See, the demonstration resulted with us looking at the absence of air around embryo Casey inside the bag (Picture 2). Not the vacume cleaner itself. Monday I will be asking Dr. Cuccio about this.

If anything this demonstration showed me how much more there is for me to learn. This is such a small concept/ fact -the presence of air everywhere- but there is SOOOO MUCH science behind it. I know I will aquire more knowledge as the years pass, but there better be more awesome demonstrations along the way! This was deff a fun day in class. Dr. Cuccio says that our jobs as *EFFECTIVE* science teachers should not be to simply pass tid bits of knowledge onto our students, but rather to get them curious about things. To get them questioning. That will last.
Well I am definitely curious. Let me know if you have any opinons on this idea, science, demontrations or anything.
Ta-Ta for now!

There is air in a vaccum cleaner... not a vaccum. And the picute (where I look like an alien or something) is to show a vaccum orhow it works. If you had something in the bag like a coke can or something, after all the air around the can was sucked out the can would crush just because the air inside the can wouldbe sucked out, too. It didn't crush me because there is sir in me and they would have had to have my head in the bag (BIG NO, NO) to do that. And I really wouldn't appreciate it. So maybe it's a little clearer?
