Potential and Kinetic Energy: Spool Racer (Document)
KEIKO: Eleanor M. of Philadelphia, Pennsylvania sent us these instructions to build a spool racer. All you need are some spools, toothpicks, pencils, metal washers, rubber bands and tape. The first thing you have to do is put a rubber band through the middle of your spool. What I do is put the rubber band on a toothpick, like this.
MIKE: Did you still have it on the other side? All right, good, cool.
KEIKO: Now... and on the other end... you put a pencil.
MIKE: There you go.
KEIKO: That's kind of loose, so you probably should double it, maybe.
MIKE: Yeah, wrap it around the pencil twice.
KEIKO: So, we'll just put this on like this.
MIKE: Yep. Now, to get your spool racer to go faster, you snap off the ends of your toothpick, so it's right... even with the ends of the spool like that. Okay, then you have to tape it down so it'll be sturdy.
KEIKO: There you go.
MIKE: Okay. Now, you hold the rubber band on one side and take out the pencil, because you have to put a washer on now so it'll go more smooth. Grab the pencil... and put it back in. And...
KEIKO: …double it. (laughs)
MIKE: Want to do the honors?
KEIKO: Okay. Now you just wind it up...
MIKE: …until it comes back to you.
MIKE: All right, here we go. Let's see how this baby works.
KEIKO: Go! It's not going...
MIKE: Oh, wait. Maybe it's too far up now. There we go!
KEIKO: There we go!
MIKE: All right, you want to race now?
MIKE: I got one ready. Welcome to the ZOOM 500.
KEIKO: Wait, how do I know if I overwound it?
MIKE: You don't. All right, ready?
MIKE: You get to say "Go ahead."
KEIKO: Ready... Set... Go!
MIKE: Oh, no!
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.
