For that reason we have included a sample lesson. Teachers, try this sample lesson yourself and then teach it to a class of students in grades 5 through 8. They will convince you that programming is more fun and more educational than using software. You have learned in your science classes that vibrations produce all sounds. We know that music is made up of sounds.
Sounds differ in several ways.
One of the ways sounds differ is in their pitch. A greater number of vibrations per second produces a higher pitched sound than a lower number of vibrations per second. Musical sounds are produced by certain frequencies . Another way in which sounds are different is their duration or how long they last. We say that a sound of a longer duration lasts longer than a sound of a shorter duration.
