Lifting with Air (Document)
GARRETT: Ashley of Ashland City, Tennessee, challenged us to see if we can lift things by using a resealable baggie and some straws. We're going to try lifting this table by putting a hole in the baggie, putting a straw in the hole, sealing the baggie and blowing it up like a balloon. On the count of three, we'll blow, okay? One, two, three.
GARRETT: That's so cool. Oh, mine popped. That's so awesome. Try holding it because some of the air will go out.
RACHEL: It's so far off of the table.
KALEIGH: I know, we couldn't... we could lift it up a little but we couldn't lift it up that much and look at the baggies.
GARRETT: This is so cool how air can lift this thing up.
MATT: When we blew air in the resealable baggie there wasn't a lot of space for the air to spread out and it was compressed. This means that the air was pushed together really tightly.
KALEIGH: We could tell that the compressed air was pushing hard because we had to push even harder with our breath to get air into the baggie.
MATT: We were able to lift the table because the compressed air pushed on the baggie and the baggie pushed on the table, causing it to lift. It's kind of like the tires of a bicycle. When they are flat, it's hard to ride your bike, but when you fill them up, the tires hold your weight and it's easier to ride.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
