Sit and silently listen.
Make a list of the sounds your can hear.
Take a look at my list.
Then decide what is that animal/object/thing doing to make the sound.
Take a look at my examples:
The singing of the bird
The whirring of the photocopier
The shouting of the pupil
Make your own poem of what the Sound collector could collect.
Rehearse yourself reading your poem and video it. Send it to Mrs B in an email.
