Welcome back to Everything under the Sun everyone! We've missed you! We've been taking a little break but now we are BACK and ready for another fantastic episode. 

This week we're learning all about SOUNDS! And we've got some very interesting questions indeed, from Sam, Florrie and Bruno.

Why do people's voices sound different? Professor Guri Sandhu answers this one, as he is a doctor who takes care of the human voice.

How do echoes work? Have you ever shouted into a big empty space, and then heard your voice coming back towards you? We learn all about the mysterious way that we hear echoes.

How did the Grand Canyon open up? The Grand Canyon is famous for its powerful echoes, and its breathtaking views. We learn about how the canyon came to be!
