1.
Did the diameter of the tubes have an effect on the pitch
of the sound produced? If it did, what was this effect?
2. Why are tubes of varying length used in this investigation? Did
the varying lengths produce varying sounds?
3. What relationship (if any) was shown with the addition of the holes
drilled in the tubes? Why might this have caused some changes in the
sound produced?
4. What is there about a recorder that makes it so easy to produce
music? What are the limitations of a recorder?
