Students practice their skills of problem solving and measurement with sound. Students are challenged to cut 4 straws so that each straw is of a different length. They use the straws to make a pitch pipe instrument, then order the straws by pitch and measurement. Teacher instructions, scoring rubric, recording page, and a sound word writing page are included. A STEM extension is added where students create a gadget that makes sound and can change pitch.
The basic lesson is in the book Rising to the Challenge of the National Science Education Standards, also sold on this website. This the fourth lesson that will also be available in a bundled packet of nine process skill lessons on sound.
