To conduct this investigation we will need to go outside.
We will need:
A way to make noise - our voices
- an instrument
A way to measure the distance - ruler
- metre stick
A way to measure the volume of the noise at each distance - garage band to record the sound
- our ears
- data loggers
Something to record our results in - table
What are you using to make the noise?
Once we have completed our investigation explain your findings.
Use scientific language to explain.
Vibration, sound waves, travel, molecules, particles, near, far, louder, quieter
If you are working at home you could use objects from around your house and ask a family member to help you.
You could use a tape measure if you have one to measure the distances at 1 metre and ask someone to make the noise, then you could see what happens to the sound as you move away.
In your red exercise book, record your findings in the table above. After you have done this, write a simple explanation of your findings.
