Today’s project comes to you from Science Buddies. The video below will show you the supplies you need and how to create your own kazoo.  You can experiment with different materials to place at the end of your kazoo:  plastic bag, wax paper, aluminum foil, paper towel, or you can even grab something from outside, like a large leaf.  You can even make a scientific chart to record your observations when you change out the material.  How did the sound of your voice change when you spoke in the tube with each different material.  Try placing a finger or two over the end of the tube when you speak in it.  What do you observe?  To make more observations, what happens when you have more than one hole in the tube?  What happens when you change the length of the tube?  Be sure to record your observations!
