Demonstrate how you can change the amplitude or volume of sound by using a tin can and a rubber band.
I can demonstrate changing the amplitude or volume of sound by putting a rubber band around a can and plucking it hard to make a loud sound and then plucking it lightly for a soft sound.

A trumpet and a tuba are blown with the same amount of effort. They sound different because A. they have different volumes. B. they produce different pitches. C. they have different amplitudes. D. they are made of different materials.
B. they produce different pitches.

How can you use a guitar to demonstrate changing or varying pitch, the frequency of a sound wave?
I can put my hands on the guitar strings and then pluck them. If my hands are close together the strings will vibrate quicker causing a higher pitch, but if I move my hands farther apart I will play a lower pitch because the strings will vibrate slower.
