Echolocation explanation template

Echolocation is a series of sound waves which reflect off about it hits. Bats are a perfect example of echolocation. Bats are not blind but they do travel in the dark because they sleep in the day and are active in the night. Bats are nocturnal mammals and they rely on their ear when their In the dark, bats use Echolocation to hunt and live.

dolphins are another great example of echolocation. When they send an echo it makes a click sound, and that sound wave keeps going like a message and once it reaches something like another dolphin it reflects back to where it came from. Once it reaches the dolphin, it will have a reply. It also show’s them the location of objects or obstacles, it show what size and shape it is. There’s also distance, the longer it takes for the sound waves to return, the more distance between it and the object. Did you know that humans can’t hear the echolocation of a dolphin but we can feel it. Dolphins also use echolocation through their blowholes and another thing is that the high frequency sounds don’t travel that far but low frequency sounds are able travel further distance and the reason of that is because low frequency sounds have more energy.

An echo is something that repeats itself for example, when your in a cave in the mountains and you yell, your voice echoes through the air bouncing of the smooth areas it hits. You notice it repeats what you yelled and repeats it about 5 or 8 times, that is what an echo is. Dolphins echolocate by slapping their nostrils together but that isn't quite nice for us or clean

Sound explanation template

For inquiry this term we are studying sound, the fascinating vibration that travels through our ears and then to our brain. Sound comes from vibration which from there it turns into molecules which travel to our brain.

Sound start’s when something or someone vibrates or moves. Then it travels through molecules that are made out of thin air. Which from there they go to your outer ear and then the through a tube called the auditory canal, then hit’s the ear drum which makes a vibration on the bones in your ear. It go’s to the auditory nerve then to your brain which translate’s the sound into words.But some vibrations are so far away that by the time they reach your ear it’s not clear enough for the brain to translate it. Sound is a wonderful element and that’s why we are learning about it.

Sound is such a fascinating element and I wonder what our world would be like without it, every word we spoke would not even be heard by our own ears so that’s why we need sound to communicate with each other and to understand each other. So take good care of your ears or you’ll end up doing sign language. Have you heard of the hearing house, I’ll tell you a story  about something really sad and really amazing. There was a deaf girl. She was part of the hearing house there is a lot of misery in that place, there was a package and it was for helping them better. One lucky her got to put in one, once she put it on she cried for ages for being able to hear again. Her parent’s were so happy and so lucky because that gadget cost millions of dollars. It was such a sad story.

Singing Trees by John Parker

Singing Trees by John Parker

WALT: Find key information in the text.

Success Criteria: I can discuss and find key information in the text.

Answer the following questions in red


What had the writer found out when he visited Noel Sweetman?
He found out that the patterns on his violins were the same as the ones Antonio Stradivari, who lived in italy in the seventeenth century. So that means violins haven’t changed for over three hundred years.

How many parts are there in a violin?
As many as one hundred-and each has to fit perfectly to work properly, even the tiniest mistake can make it out of tune.

What does Noel do with deer antlers?
He made planes that were made out of deer antlers. I have no Idea why he did that.

Why do you think violins have not changed much over hundreds of years?
Because a violin has more than one hundred part’s, you need all the parts for it to work properly and perfectly.

What does the word hollow mean?
It means that the inside of the violin is completely empty and but out looks like its full of wood, this is called hollow.

Why does a violin have specially shaped holes?
It allows air to travel and move in the sound box which makes the sound of the violin work.

Why are various parts of the violin from different places around the world?
Because the violin needs particular pieces of material which help it find its voice, the violin is made out of wood from all around the world


Analyse the last paragraph on page 23, what do you think the author means when he says this?
since the violin is made out of wood from around the world, another reason might be the sound of peace and relaxation just like the trees around the world.

Do your own research and find out how a violin produces sound?
The violin makes sound through vibrations. This vibration can be achieved by plucking or bowing the strings. The strings that are normally suspended above the body, the vibration will be transferred through the bridge to the body where the sound will be amplified.

Write this in an explanation about how a violin produces sound?
a violin is produces sound through vibrations. The strings vibrate and air inside the instrument vibrates to make the sound louder.

Write a list of other string instruments similar to a violin: guitar, viola, cello, and string bass.
