Through research on how animals communicate, I can explain how sound vibrations are carried by waves through air, water and other media.

SCN 2-11a

Benchmarks:

· Discusses and demonstrates through experiments how sound travels differently through air, water and solids.

· Explains how hearing is limited by a range of factors, for example, age, position, and flexibility (direction) of ears.

Understanding Sound Worksheet

Can be used to identify the mental model pupils are currently using to understand how sound travels. The common misconception is that 'sound' travels from the noise making object, through the air like a basketball and into the listening ear. Can also be used as a pre and post assessment, identifying how the child's understanding of how sound travels has changed.

How to make a wave machine in your classroom!

For a primary classroom the key learning from this activity is that sound is produced when an object vibrates. When an object vibrates it in turn causes the air molecules surrounding it to vibrate, these vibrations spreads out in all directions like a ripple in a pond. A key point to note is that the individual molecules are not travelling from the vibrating object (the drum for example) to our ears, but rather there is a wave or domino effect as the vibrations travel.

In the wave machine shown in this video children can clearly see that the individual Jelly Babies do not travel from one end of the machine to the other, however, they can see the vibration of one Jelly Baby pass to the next and so on creating a wave.
