Pitch: Straw Kazoo (printable instructions) (Document)
RAY: Sarah and Jonathan S. of Jackson, Michigan, sent us the instructions to make a musical instrument using a drinking straw. All you do is flatten one end of the straw.
CAROLINE: Like that?
RAY: Yep, that's pretty good. Then with a pair of scissors cut out a V shape in the straw. Cool. Just like that.
RAY: This will act as a reed, just like in a clarinet.
CAROLINE: Place the V end of the straw in your mouth so that the V is just past the inside of your mouth. Then press on the V with your lips while blowing, like this— this might take some practice. Maybe we have to kind of open it up a little. Oh, here we go— I think this'll work. (squeaking) (blowing note)
RAY: Brilliantly done. (blowing note)
BOTH: That's awesome.
CAROLINE: (blowing note)
RAY: Here's another cool thing you can do. Cut the straw and then blow on it. Listen to how the pitch gets higher. This is because a smaller straw vibrates differently.
CAROLINE:(notes getting higher)
RAY: Let me try. (notes getting higher)
CAROLINE: Oh, that's awesome!
RAY: (notes continue to go higher)
CAROLINE: That's awesome.
RAY: See if you can make a musical instrument that uses vibrations in different ways.
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.
