Making an Instrument!

We continue to learn about sound and the sense of hearing-how/low pitches, vibrations, echos, protection of one's ears, etc.  One of the favorite activites of this unit has always been our version of a harminoca!

I passed out 5 plastic straws and had my students cut them in various places.  We then lined up the ends from shortest to longest and taped the straws together.  We then predicted which straw would have the highest and which one the lowest pitch!  Once they tried out their new instrument, they could not stop using them!  I think we had a band of 19 students playing the same instrument!
