What on earth is a yell, what in tarnation is a whisper, and how in the hippopotamus do we use them? Let's give it a go and find out together! In this fun and interactive children's book about volume, we'll explore how to use our voices to control just how quiet, and how loud, we can be. Practicing volume control will set children up for success in real-life situations when they need to be aware of the power their voice holds.
