Sounds and colours are all around us, all the time. And sometimes we don’t really notice. The Sun is in the sky, even on a cloudy day; the stars are always there whether it’s day or night. We talk to each other, enjoy music and use machines; and animals use sounds to communicate too. It’s easy when we are busy at school or work or at home or in between to take for granted that our world is colourful and noisy.
But what are sound and colour made of? Do they move? And, if so, which is faster?
Fish are cold-blooded animals that live in water. Most fish have scales on their bodies, use gills to breathe and have fins instead of arms or legs or fingers or toes. And they range enormously in shape and size – from tiny seahorses to huge whale sharks!
But have you ever wondered if and how fish can hear? We have! So, let’s find out more about fish and how they sense the watery world around them…
If, like us, you’re a fan of the Trolls movie, you’ll know that King Peppy looks for three things in a new home: fresh air, clean water and sweet acoustics! But what does he mean? And can you find acoustics in the place where you live?
I speak every day – to my family and friends, to the people I work with and to other people that I meet. Sometimes I use my voice to sing or hum or whisper or shout! My daughters and husband use their voices too; even Fishfingers the cat purrs and meows. As you might imagine, our house can become rather noisy!
Speaking is one of the ways that humans communicate with each other. But how do we do it? What happens inside our bodies to make sounds that other people can understand?
My younger daughter asks this question all the time. She only recently learnt how to ask ‘what’s that noise?’ and has become very fond of asking it! So, I thought this would be a great opportunity to talk how sounds are made and how we hear them.
