Jingle Bells Science

Description and Materials

Description

Any time we play or sing a song we can hear beautiful sounds. Sounds are waves in the air.
The shape of the waves results in different notes and high or low volume. Sing Jingle Bells and discover the science behind. Let’s see the sound together!

Materials
  • Lyrics
  • A bowl
  • Pinch of salt
  • Clear kitchen film

Instructions

Instructions

Cover the bowl with your clear film, very very tight in order to build a sort of drum.
Place a pinch of salt on the surface.
Start to sing close to the bowl and observe what happen. Sound is made by waves that make the film vibrate. If you sing louder or change notes, you may have different effects.
You can also clap your hands or use pan and a spoon as “drum”.

Please, share your creations on twitter using the #adventSTEM
We are looking forward to seeing what you’ve created!

Lyrics

Dashing through the snow
In a one-horse open sleigh
O’er the fields we go
Laughing all the way
Bells on bob tails ring
Making spirits bright
What fun it is to laugh and sing
A sleighing song tonight

Oh, jingle bells, jingle bells
Jingle all the way
Oh, what fun it is to ride
In a one-horse open sleigh
Jingle bells, jingle bells
Jingle all the way
Oh, what fun it is to ride
In a one-horse open sleigh

Sound is a vibration through a medium such as air, but it can propagate also through liquid or solid.
The sound wave as a shape, the frequency of the wave determines the note (A, B, C..).
While is the amplitude of the wave to determine if the volume of the sound is higher (louder) or lower (soft). The volume is measured in decibels dB, while the frequency is measured in Hertz Hz.
