Слайд 4Sound investigation
Around the room there are different everyday objects to

make a sound with.

ALL: Find out how the sound

is made.
Most: Find out how the sound can be made louder/ quieter.
Some: Find out how the sound can be made higher/ lower pitched.

Fill in your table as you go.

Слайд 5

Слайд 6The guitar string makes the air particles
Vibrate and move

towards the ear.

Слайд 7Air particles bump into air particles inside the ear
and these

particles vibrate.

Слайд 8The vibrating air makes the ear drum vibrate
and we hear

the sound.

Слайд 9Fill in the gaps task
Fill in the gaps on how

sound travels to our ears.

Extra challenge: Why can the sound

of this alarm clock not be heard by the end of the video? Answer in your books.

Слайд 10Fill in the gaps task
Any sound is caused by something

_______ . The vibrating object causes the _ _________ next

to it to vibrate; those air particles then cause the particles next to them to vibrate.

In this way, a disturbance of the air moves out from the source of the ______ . Sound travels through the air as a sound _____ , and may eventually reach the _________ of a listener.

When we hear a sound, air vibrates against the ___ ____ causing it to vibrate also. The vibrations are passed on by 3 small _____ to the cochlea. Here in the cochlea, the vibrations are changed into _________ messages. These messages travel along a nerve to the _____ .

Слайд 11Self-assessment
Any sound is caused by something vibrating. The vibrating object

causes the air particles next to it to vibrate; those

air particles then cause the particles next to them to vibrate.

In this way, a disturbance of the air moves out from the source of the sound. Sound travels through the air as a sound wave, and may eventually reach the ear of a listener.

When we hear a sound, air vibrates against the ear drum causing it to vibrate also. The vibrations are passed on by 3 small bones to the cochlea. Here in the cochlea, the vibrations are changed into electrical messages. These messages travel along a nerve to the brain .
