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.
