Sound can reach another objectYear 2 Science · T1 W1–2 · Texts / Sound
Source review complete · local suitability still needs review.
A sound source vibrates: it moves back and forth. Sound energy can travel through air. When sound reaches another suitable object, that object can vibrate too.
One real example is the eardrum. Incoming sound waves can make this thin part of the ear vibrate. Hearing involves more steps after that; this short text does not show the whole ear or test anybody’s hearing.
We may not see tiny, fast vibrations in a gentle classroom try. A hand moving paper is a direct-contact action. It is different from sound arriving from another source and making a receiver vibrate. A drawn arrow explains the idea; it is not a measured result.
