To classify is to sort objects into groups.

Noise pollution is when sound becomes extremely unpleasant or unbearable and is a problem.

The volume of sound is measured in decibels (dB).

Noise pollution: acceptable decibel levels (non-statutory)

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

This unit explores how sounds are made through vibrations, how they travel through mediums, and how pitch and volume relate to vibration strength. It also covers why sounds get fainter with distance. The emphasis is on practical enquiries, observations, and using results to draw conclusions.
