Straw whistles



We made whistles from straws.  Teacher cut the top of each straw into a point.  When we squeeze this straw between our lips, we can make music.  Some of us could do this, but some of us need more practice.  Some of us even managed to play "Jingle Bells" on our straw whistles. 
Teacher started with a long straw which made a very low sound.  Then, as she was playing her straw she cut it smaller.  Each time she cut the straw it got shorter and the sound got higher.  We can see that long straws make low sounds while short straws make high sounds.
