BOY 1: We had to design a balloon car... out of orange juice boxes. The wheels are made of spools... And we're using balloons.
BOY 2: And you inflate the balloon...
BOY 1: And the force of the air coming out of the balloon was to make the car go, so what we really had to do is design a good car... That would go far...
BOY 3: For the longest time.
EVERYONE: (all exhaling loudly).
BOY 1: You have to have the right size opening at the end, because if you let the air out too fast, it'll just go fast for a second, and then it will stop. But if you let the air out too slowly, you won't get enough force. I tried with this long, skinny balloon, and what I realized is that the balloon was starting to flop over and get in the way of the wheels.
BOY 1: So I had to design this to keep the balloon straight.
BOY 4: I put the wheels farther apart so it wouldn't, like, be able to turn like this more.
BOY 5: Caramba!
MAN: Ah! Okay.
BOY 6: There's always a trade-off for how fast it can go and how far it can go.
MAN: Let's go. Let's get a bunch of them going there.
BOY: It worked! All right! Oh, nice! Yay! (laughter)
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.
