A vibration is when an object moves very fast from side–to–side.

A loud sound is one that is easily heard, such as shouting.

A quiet sound is one that is not as easily heard, such as a whisper.

The volume of a sound is how loud or quiet it is.

Science

In this Introduction to sound unit, pupils learn that sounds are made by vibrations and that vibrations travel through a medium to the ear. In the Sound, light and vision unit, they will build on this knowledge to learn more about how sound waves travel through different types of medium and are absorbed and reflected.

Pupils will draw upon exploration of making and listening to different sounds in EYFS and their own everyday experiences. In this Introduction to sound unit, pupils will build on this knowledge to identify how sounds are made, associating some of them with something vibrating
