The gunners

WALT find information
We are looking at sound
1. Things that vibrate or move backwards and forwards very quickly make a sound
2. Elastic bands and rulers are sources of sound
3. Often we can't see vibrations because they are so fast but we can still hear the sounds
4. Sources of sound are all around us
