Explanation of how sound is created:

Introduction:

I’m going to explain how sound is created from my guitar. As you already know I have made a homemade guitar. You won’t really hear any noise if I play it. But when I play my guitar, the sound waves suddenly vibrate.

Main reason:

Answering ‘how’

The string (rubber band) vibrates when I strum it. So thats how the vibration of the rubber band creates the sound waves.

Conclusion:

If you have done the guitar and it looks like one, then congratulations because you have just made a homemade guitar. You have followed my instructions and have completed it. Was it easy? Did you understand the instructions? Making a guitar with cardboard things is very easy. Have fun strumming your guitar!

Samoan Week

This week is Samoan week. It is a very special day for the Samoans, our school Point England has celebrated it by our Samoan group performing as well as Tamaki college Samoan group. I was in the Samoan group. Our school has declared Samoan week for Tamaki Makaurau a.k.a Auckland. It was very nerveracking because I just joined the Samoan group on Friday, and the Samoan group was already been made because the dance that we did was from the FiaFia night.

My grandparents Rev. Lei’ite Setefano and his wife (my grandma) Lealofi Setefano came to support our school for the Samoan week, and he is a very good friend of Mr Burt our principal. Also Sam Lotu-Iiga is the NZ Parliament for Maungakiekie. He has come to support just like why my grandparents came, and he was a very good friend of my mum. They went to University together.

Mr. Burt and the school were saying in the hall “Taofi mau i au measina” which means “Hold fast to your treasure”. After both of the schools had perform everyone had left and only Tamaki college and our Samoan had morning tea.

HAPPY SAMOAN WEEK!!! Cheeehoooo!!

How does musical instrument creat sound?

1. Intro:

Guitars are one of the most enjoyable instruments in the world. A lot of people play guitars more than the other instruments. Do you want to know how a guitar works, well this story is about a guitar!

2. Parts of a guitar:

On a guitar there are six strings. It goes from low to high. On the guitar there is a headstock, tuners, nut, neck, sound hole, body and bridge. All those parts are very helpful. The headstock is on the top where the tuners and nut are. On a guitar there is a neck, the neck is the long part where you play the chords. The sound hole, is when you strum a guitar it goes into the hole and rebounds back. Lucky last is the bridge, the bridge is on the body, it holds the strings on the guitar.

3. How is sound created from a guitar?

The guitars sound is created by the soundhole. When a string from a guitar is played, the sound waves vibrate through the air and it goes into your ear. When someone plays a guitar, it goes inside the soundhole.

4. How to play a guitar:

You play a guitar by putting your fingers on the chords on the neck. Then when you strum a guitar it will sound good. Once you get the chords all you need to do is to get the beats right and you’ll know!

5. Conclusion:

Guitars are fun and easy to play. It will sound good if you learn how to play a song.

Funnel ears science experiment template

Science experiment:

Question: What will happen to the sound if I change the shape of a piece of paper? (e.g. from a flat shape to a funnel shape)

Links to research about Sound:

http://www.thetech.org/exhibits/online/robotzoo/guide/bats_and_echoes.html

http://www.ask.com/question/how-do-animals-hear

Hypothesis: (What do you think will happen?) e.g. I think that….

I predict that when you make a funnel shape, it will be louder than the flat shape.

Materials needed:

paper and sellotape and tissue

Experiment (procedure):

Step 1 - First hold a flat piece of paper against your ear. Block your other ear with your hand. Get your partner to speak to you. What is the sound like? Can you hear clearly?

Step 2 - Next, roll the piece of paper into a funnel shape. Put the funnel against your ear. Face the funnel towards your partner and listen to them speak. What does it sound like? Can you hear clearly?

Step 3 - Next, face the funnel to the side while your partner speaks to you. Does it make a difference to the sound that you can hear?

Step 4 - Put some cotton balls or tissue paper into the funnel to block one end. Does it make a difference to the sound you hear?

Step 5 - Next, roll the piece of paper up and l

Data (What happened?)

	Shape/object/materials	Results:
1	flat piece of paper	It didn’t make a difference
2	funnel facing to the front	It was loud and clear
3	funnel facing to the side	It wasn’t clear it wasn’t loud it just sounded blurry
4	cotton ball blocking funnel	It sounded like someone speaking while my ears were blocked
5	rolled up piece of paper (facing to the front)	It was loud, and my ears were sore
6	rolled up piece of paper (facing to the side)	I couldn’t hear my partners voice, I just heard everyone in the background.

Observations:

I just realized that when you roll up a paper and someone talks through it it will sound really and it will hurt your ears .

Conclusion:

The flat paper will not be loud. But then when you roll it up, it will sound really loud. So I guess that my prediction was wrong. The funnel paper wasn’t loud, it was the rolled up paper.

Where's the sound (summarise)

When we are in earth and you hear a space ship blow up, you hear a lot of noise. But if you are in space and you hear a space ship blow up you'll hear completely nothing.

A sound is a type of energy. An object can move by the sound waves when it vibrates.

When you put a rubber ban on two fingers (index and middle). You flick one side and it will vibrate. That is how the sound waves vibrate through the air.

Sound waves can travel through anything. Liquids, gasses and under water. Sound waves can even travel through a brick wall.

Space and vacuum are the same. Basically space is like a vacuum, they both have no matter. So when a ship blows up in space you shouldn't hear anything because there is no matter.

Here is what we have summarised: Where is Sound

Sound

Sound:

Types & Impact:

There are many types of music in the world, like Jazz, Hip Hop, Rap, 70’s and 80’s and many many more. Music can sometimes help you think, relax and even make you sleep. I know music is fun and groovy, but sometimes it can also be very dangerous. Because very loud music can affect your eardrums. If your eardrums are damaged you’ll permanently lose your hearing. So make sure that your music is not too loud before your eardrums break.

Hippocampus:

Have you heard of a word called hippocampus? A hippocampus is the part of your brain that brings lots and lots of memories from the past. There are many more different types of music than in the past. There is Hip Hop, Rap and R&B. When adults listen to old songs from the past like 80’s and 70’s, Jazz, Blues and Classical the hippocampus will help bring some of  your memories back.

Singers and Instruments:

We have lots and lots of singers in the world and from different countries. There is Beyonce, Bruno Mars, Nicki Minaj, Eminem, Jason Derulo and lots more. Their songs is what we listen to in my age. Lots of people like to play instruments. Such as guitar, piano, drums, bass and heaps more. The guitar, when the string vibrates it makes sound waves. They are all enjoyable.

Emotions:

Some songs can get you into mixed emotions. Like sad songs, it can make you cry and feel really emotional. Slow songs can make you fall asleep right on the spot. Your eyes will slowly close by the slow tune of the song. Hip Hop songs will obviously make you dance, and you’ll have lots of fun.

Sound:

The sound waves vibrates into the air then it goes into your inner ear, which goes to your eardrums that has tiny little part of hair. A cochlear nerve takes the sound waves from the inner ear to the brain. For an example: When someone is playing music on a speaker and you hear it. The sound wave vibrates into your inner ear and thats when the cochlear nerve carries the sound waves to your brain.

Science Experiment

Science experiment:

Question: What will happen to the sound if I cut the straw shorter and blow through it?

Links to research about Sound:

e.g.

http://condor.admin.ccny.cuny.edu/~ms6785/page2.html

www.thefreedictionary.com/sound

Hypothesis: (What do you think will happen?) e.g. I think that….

I predict that the straw will go in a high pitched sound when we cut it.

Materials needed:

Scissors and Straw

Experiment (procedure):

e.g. Step 1 - Crease the straw  2-3m long on one end

Step 2 - Then using the scissors again cut the end of the straw into triangle 1.5 metres long.

Step 3 -  Put your lips just over the cut end of the straw (triangle part)

Step 4 - Squash the straw softly with your lips, blow through it

Step 5 - Cut the straw shorter and see what it will sound like

Data (What happened?)

15cm Long Straw -	It just made a low squeaky sound
10cm Long Straw -	The sound went a little higher
5cm Long Straw -	The sound went really high pitched

Observations:

When the straw was 15 cm long, it just went into a squeaky low sound. But I have just discovered that every time you cut the straw shorter the sound goes higher and higher.

Conclusion:

When you cut the straw it goes into a high pitch. So my prediction and my hypothesis was correct. It did go into a high pitched sound.

What can I hear?

Sound: What can I hear?

Team 5’s Inquiry focus this term is about Physics and the Science of ‘Sound’.

This week you are going to write an explanation about the different types of sounds that you can hear in your environment.

Think about the sounds that surround you - at home, at school, outside.

What types of sounds can you hear? Where do they come from? Use the table to help you organise your ideas:

	Home	School	Outside	Other
What types of sounds can you hear?	Television, phone ringing, shower running	people tapping, people tapping, typing	people laughing, kids crying, people talking	busy traffic, cars beeping,
Which sounds do you like listening to? Why?	Dog barking, because I know that my dog is here.	Typing, I like when people type because its just sound so cool.	People talking and laughing because I just want everyone to be happy.	Cars driving past, because I don’t want everything to be quite.
Why sounds are annoying? Why?	Television annoys me when I’m trying to sleep.	When I’m trying to read a book, it’s so annoying when people shout inside class while I’m trying to read a book/or my writing.	People fighting that annoys me because I’m scared that something might happen.	It is so annoying a door closes slowly and all you hear is door making ugly noises.

Finally, think about what your world would be like if you didn’t have sound. What would it be like if you couldn’t hear a single thing, or if you had to live in absolute silence? What do you think it would be like?

Sound is very important. That’s what our ears are used for. Without sound everyone will be bored, living in completely silence. Sound is fun. There are lots of sounds around the world, like music, television and people talking. Sounds can also be annoying. Sometimes you just want silence. But most of the time everyone wants to hear sounds.

I love hearing sound because of music. Music makes me feel relaxed. Everyone loves to hear music. I hear it everywhere, on the radio, television, phones, ipads and on all the technical stuff. The sounds I hear at home are the television, phone ringing, shower running etc.

If we lived in a world with no sound but only silence, it would be pretty creepy. Because with no sound in the world, we would be living in silence. Now that’s a world I don’t want to live in. Living in silence will definitely be awkward. We might as well be deaf people, because that’s a world that deaf people experience. They can’t hear anything, only silence.

I would really hate to live in a world with no sound. Imagine no music and no singers. I love listening to music. No music means no Beyonce, no Bruno Mars and all the other great singers. Would you want to live in that kind of world?? Well my answer is definitely no! Also if we lived in a world with no sound it can be very dangerous. But luckily we live in a world of sound.
