Today I will be explaining to how does the sound get underwater including the Kina, if you do not know what a kina is it is a living organism that looks like a hedgehog because it has spikes on the body of it. The Kina vibrates the sea by their rasping teeth, as they bite on some rocks the waves keep vibrating and making huge noise,
also when the kina makes the noise then it makes the other animals weak.
Kina eats algae.
it is the time where it tell you that I am writing the body part .When the Kina is on the rock in the sea then the Kina bites on the rock with its rasping teeth and then the sea vibrates, the other animals in the sea get weaker and weaker then it disturbs the animals. The Kina eats the algae and then the razor teeth go on and on and on. Also some of the Kina’s are ok or like it to make their living habitat a Coral reef.
The sound waves are going up to the other sea animals, maybe the Kina is doing this because it is his enemy or that he doesn’t like them maybe it is his friends and they were just playing. The wonderful sound waves can go from a long way out it and go up to nearly the whole sea!. Next the animals run away from the Kina.
The Kina is very special in ways because sometimes they can kill other animals just by vibrating and that is good because some of the the animals can eat us, and kill us
for example sharks can kill us, Hammer fish and big fish.
Also in the water some people go fishing and then their boat might rumble a bit if they are really close to the spot of where the Kina is and if they are even far they might feel it because the sound is strong. Also can affect others.
Now, you know how sound travels underwater from a Kina, and now you can also tell all your friends and your mates. I hope you found this explanation very helpful also you could maybe make a explanation for me about the kina or something else.
Anyways, I hope you found this very very helpful to you because if you are reading this and you didn’t know much about Kina and sound then what would you read?
In week 4 of term 3 our class has been focusing on learning how to write great explanations about how sound travels underwater. We have expanded our vocabulary in our inquiry topic ‘The Noisy Reef,’ and learnt about the structure of a great explanation piece. It was quite a challenge, but we really enjoyed watching clips to stimulate our ideas and having discussions about terms which were new to us.
