Try
this! Put your hand on your throat and start singing. Can you feel
your vocal cords vibrating (moving back and forth)?
Use
sound waves to make sugar dance!
Can
you play Mary Had a Little Lamb using only a spoon and
8 glasses filled with water?
Show
this to a grown up!
Sound
travels in waves. The higher the frequency of the wave, the higher the
pitch of the sound. The lower the frequency, the lower the pitch. Try
helping your child to experiment with frequency and pitch by conducting
the ZOOM experiment Glass Xylophone. Then encourage
your child to watch a music video (one that you both enjoy!) and think
about how the different instruments create vibrations.
