Changing Sounds: Pitch and Volume | Explanation Writing Pack | Year 3/4

This fully resourced two-week explanation writing unit focuses on the science of Changing Sounds: Pitch and Volume. Pupils will learn how sounds are made, how pitch and volume change, and why these changes are useful—all while developing the skills to write clear, well-structured explanation texts.
