Question: Explain how sound is produced by your school bag?

Sound can be produced by many things inside a school bag. For example, when the bag is moved around, the items inside create friction between the bag, its contents and the other objects and cause a shuffling noise. Items like coins, keys, and stationary can create a rattling sound when they are moved around in the bag. Percussion items like an instrumental case, or even an umbrella, may create a tapping sound if they make contact with the pockets or lining inside the bag. Finally, when weighty items like books are moved inside a bag, they can create a thumping sound on the surfaces that they come into contact with.
