Put the Steps in Order – Understanding Sound
Plan an investigation to show that sound is produced by vibrating sources, propagates through material media, cannot travel through vacuum, and forms a longitudinal wave in air.
You are provided with the following materials:
Rubber band, tuning fork, water, wooden desk, bell jar and slinky.
Arrange the following jumbled steps in the correct order to complete the investigation.

Answer variants:
Observe that the disturbance in the slinky consists of compressions and rarefactions moving along its length.
Conclude that sound is produced by the vibration of an object.
Push and pull one end of the slinky along its length and observe the alternate crowded and spread-out regions formed in it.
Pluck the stretched rubber band and observe its vibration while listening to the sound produced.
Place a vibrating tuning fork inside a bell jar and gradually remove the air while observing the sound heard outside.
Observe that the sound becomes weaker as the air is removed, even though the source continues to vibrate.
Tap one end of the wooden desk and listen for the sound at the other end.
Conclude that sound can propagate through a material medium and that a vacuum does not provide a medium for sound propagation.
