Investigating Sound

As part of our science unit, we are learning about investigating sound. The class made a guitar out of a box and used 3 different rubber bands as the strings. One rubber band was thick, another medium thickness and the last was thin. We learned that various things such as thickness and tightness of a string will cause it to make a different sound. We then compared our guitar to other string instruments and realized each string will give a different sound based on what we learned in our experiment. As we plucked the strings on our guitar we kept a chart to record which string made what kind of sound. We learned the thick string made a low sound, the medium made a medium sound and the thin string made a high sound. What a hands on way to learn!
