Making Sound With String  Have you ever made sounds with a
string? How did you do it? What kinds of sounds did the string
make? Could you change the sounds it made? Here we'll explore
different ways to make and change sounds produced by string.
Think about a musical instrument that has strings. How would you
describe the sound? What sounds do you think you could make with
a string that is not part of an instrument? Thread the end of
the string through the hole in the bottom of the plastic cup.
Start with the thread inside the cup. Pull the string all the
way through the hole; the washer will be inside the cup and keep
the string from pulling out. Think of ways you could use this
string and holder to make sounds. What do you think you could do
with the cup? How could you make the string vibrate? Hold the
cup against the floor with one foot. Change the length of the
string by winding more of it around the pencil. Pluck the string
to hear the differences in pitch. Try this with another student
or friend. Remove
