Sound is caused by vibrations in matter.
Vibrations can travel through objects. In particular, they can
travel through air (and thus reach our ears).
The loudness of sound increases with the strength of the vibrations.
The pitch of sound depends on the vibrating material and its size.

girl is continually told by the adults in her world to SH!! Finally
the SH-ing becomes too much for her. She goes outside and yells,
screams, and makes all kinds of other noises before being quiet
are sounds produced? Have the children hold their hand on their
larynx (throat) and say their name. Tell them that what they feel
is a vibration. Ask the children to say the days of the week and
months of the year, to growl, whisper, cough. Do all these sounds
produce the same vibrations? Ask the children to describe the differences
in the vibrations.
Give each student a rubber band. Ask the students to produce a
sound using only the rubber band.
Have the children hold a rubber band tightly between the index
fingers of both hands. They can rub their chin across the rubber
band to produce a sound. What happens if they stretch the rubber
band even more? What happens if they use a thicker rubber band?
A thinner rubber band?
a ruler or tongue depressor on the edge of a desk with the palm
of one hand while gently plucking the free edge of the ruler with
the other hand. Change the length of the protruding part of the
ruler. Ask the children to describe how this changes the sound.
a tuning fork with a rubber mallet or against your knee. (Never
strike a tuning fork against a hard surface.) Place the prongs into
a container of water. Ask the children to describe what they see.
an oscilloscope. Cut the ends out of a soup can and cover the rims
with tape for safety. Stretch a balloon over one end. Hold the balloon
in place with a rubber band. Stick a small mirror onto the balloon
with white craft glue. Allow this to dry overnight. Hold the open
end of the can to your mouth and cup your hands around it. Talk
into the can while a partner shines a flashlight on the mirror.
Your voice will cause the balloon to vibrate, and this vibration
will be enlarged in the reflection of light on the wall.
the children look through magazines and cut out pictures showing
objects that make sounds. Have them decide if they think each object
makes a loud or quiet sound. They can glue each picture in the appropriate
column of the reproducible worksheet. Encourage the children to
share their worksheets, giving reasons for where they placed each

things that do not make sounds.
Take a Trip:
Go on a sound walk
on the school grounds. No talking, only listening to the sounds all
around. When you return, divide the class into groups and have each
group list the sounds they heard. Combine the lists. How can the sounds
be grouped? (For example, into natural and human-made, loud and soft,
short and long, etc.)
where you live, a walk at different times of the year can give students
the experience of different sounds, such as the rattle of dry leaves
in the fall, the crunch of snow in winter, soft footsteps in spring,
