This week’s science lesson we have been understanding what happens to sound as it travels, describing how sounds change as they pass through different mediums (solids, liquids and gases) and test how sound travels through different materials.

Fun facts

Did you know that sound is a vibration that travels through different materials?

Sound is made when an object vibrates. When an object vibrates, the air around it begins to vibrate, and these vibrations enter your ear as sound.

These vibrations create sound waves that then travel through solids, liquids and gases but not a vacuum, otherwise known as a completely empty space.

Sound travels four times faster in water than it does in air. The denser the medium is, the faster sound can travel through it. It travels at around 1,230 kilometres per hour.
