DIGITAL DOWNLOAD: you receive a printable A4 PDF to print at home or school. No physical book is posted.

Across 32 pages, this Year 4 booklet works through how sounds are made and how they travel, before explaining how the ear itself works. A ruler twanged off the edge of a desk sets the tone for "Big or small?" and "High or low?" questions linking vibration directly to volume and pitch. A closing "Can you keep the noise down?" section brings sound management into everyday life. Every question in the Year 4 National Curriculum carries its own Watch the video button here, pointing straight to a free lesson by Brenda Hayles on YouTube. Diagrams of the ear and photographs of vibrating objects fill the booklet, and new words such as vibration and pitch are explained at the back.

Inside:

• Six questions, from how sound is made to the ear
• A video link on the contents page for each question
• Diagrams of the ear and photographs of vibrating objects
