Sound In Space!

Sounds in Space

List 3 interesting facts that you learned from the article:

1. In space there is no air, so if you say anything no one will hear you.

2. Sounds are caused when something vibrates.

3. Vibrations can travel through solids things as well as air.

Why can’t we hear sound in space?

Because space is a place of silence and there is also no air and also nothing for the vibration to travel through.

How did NASA record the sounds of interstellar space?

The data was stored on an old fashioned tape recorder!

What does deep space sound like?

it’s like Dawn Chorus of birds singing in spring from super bass!

What does the plasma wave detector detect? How do they turn this into sound?

It senses waves of electrons. Play the data through a loudspeaker and listen.

How to play net-ball!

How to play net-ball!

Do you know how to play net-ball? Well, if you don’t here is an explanation on how to. First, there are 7 positions that any of your teammates can play. For example Goal Shoot, Goal Attack, Goalkeeper, Wing Attack, Wing Defence and Centre.

To play have to know the basics. Passing, Not Stepping and . As you can see down below is what the court looks and where the positions go just before the whistle. In net-ball there is a round ball that is used. There are 2 goal posts  that the goal shoot and goal attack can shoot in. As you can see also in the picture that there are lines and 2 circles at the end of each end of the court. The lines are bound trees which of the positions cannot pass.

If you are not three feet from the person you are defending the ref will call obscuration. If you accidentally hit a person with the ball that is called contact. If you cross the line on the court when you are not supposed to that is called Braking, which is not a good thing. The ref will also blow the whistle and your team or the other team will get the ball. It depends who’s centre pass it is.

When you are Goal Shoot, your team is counting on you to get most of the goals in. Goal Attack is when you are also a shooter but you are just a back up for the Goal Shoot. GoalKeeper has to stop the Goal Shooter from shooting the ball into the goal. He or she and also around the court but within the circle and past the line.

Wing Attack is when you are a wing and the centre will pass it to you if there is no one else free. Wing Defence is like Wing Attack but different. You have to defend wing attack from the other team that you are versing. And the last position and the last one is Centre. You have to run around the court and be able to be there to get the ball.

How to post a piece of writing onto your blog.

How to post a piece of writing on your blog.

Do you know how to post a piece of writing onto your blog? Here is an explanation on how.

First, you have to have a blog and an account so you can log in and start posting things onto it. Then, you should be able to access and do anything or post anything on your blog. But, the main thing is you have to make sure that your writing is all done and ready to be posted.

Next,  you are just going to post your writing on your blog, if you want to be ahead have the blogger link (blogger.com) already open as well as the doc with your writing.

When, you click onto the blogger tab, click on the little sign that looks like a pencil. Then when that opens, write in a title in the little rectangle on the top of the screen next to the word Post. After that click back on your doc with your writing and select it all (Ctrl A) and then copy and paste ( Ctrl C - Ctrl P) it in the big rectangle shape on the blogger TAB.

After, you have done that your writing should be ready to post. But, first write some labels. To do that in the top right corner there should be a little rectangle shape with a word ‘Labels’ in it. Click on it and put things for example ,your name, the word ‘google’, what year it is, what term it is, what writing is about etc. When you have done that click post and then it should appear on your blog and will be saved.

Explanation of Homemade Instruments!

I’m going to explain how make a homemade Can Drum. It is very simple but can be hard at times if you DON’T follow the instructions correctly. Along the way I am going to be taking you though the instructions.

The materials that you will need are a can, Rubber Band and a piece of paper. First, cover the top of the can with the Piece of Paper, using the Rubber Band wrap it around the top of the can to keep the piece of paper down. Make sure that it doesn't come off.

Now you can see that your Can Drum might just look like a piece of paper covering the top of the can with a rubber band tied on the top to keep the paper down. But wait, when you hit/tap the top of the can it will make a little bang sound and if you make a little rhythm it could be a little jingle.

Funnel Ears Science Experiment

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

Hypothesis: (What do you think will happen?) e.g. I think that the sound of the paper will be a echo sound like in a tunnel.

Materials needed

Piece of paper and tissues.

Experiment (procedure):

e.g. 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?)

No	Shape/object/materials	Results:
1	flat piece of paper	It was clear and didn’t make a difference.
2	funnel facing to the front	It sounds like a echo.
3	funnel facing to the side	It sounds like you are inside someone else and like you are whispering
4	tissue blocking funnel.	It just sounded clear.
5	rolled up piece of paper (facing to the front)	It Sounded like I was having a conversation.
6	rolled up piece of paper (facing to the side)	I could just hear the sound in the background.

Observations:

It turns out that half of my hypothesis was right. When the paper was flat and Nikita spoke it sounded like Nikita and I were having a conversation. When we turned the paper into a funnel shape and faced it to the front it sounded like an echo. When we faced the funnel sideways it sounded like you were inside someone else's head and they were whispering. When we added a circle shape tissue at the end it sounded like someone was shouting to you across the room. When we rolled up the piece of paper facing the front it sounded like

someone is talking to you but echoing. Finally, we faced it to the side and it sounded like someone was whispering to you.

Conclusion:

Just Like my hypothsis was right. And my Observation.

Summary On Hearing!

This article was all about this boy named, Dylan Vaughan. He was born profoundly deaf. He had to have a cochlear implant.  The health system paid for the first implant. So, his parents (Jo and Neil Vaughan) fundraise so he could. They raised $50.000 and paid for the second implant. Yes, he had 2 implants. But, now the government is paying for 2 cochlear implants for children under 6 years of age.

How Sound Affects Your Brain!

------------

How does music affect our ears? Well, if we are listening to music with little ear buds and the music is too loud, it can damage our hearing and you can’t get it back. You will just be deaf and wouldn’t be able to hear anything. But it doesn’t only affect your ears, it can affect your body.  

There are all different types of music. For example Hip Hop, Jazz, Pop, Rap, Soul, R&B, Opera, Blues, Classical, Reggae and 70’s and 80’s and many more. Sometimes, if you listen to music it can bring back old memories. My favourite is hip hop. Some other peoples favourite’s might be Opera or even the Blues.

All around the world but mostly in America, there are all sorts of artists. For example, Beyonce, Will.I.Am, Taylor Swift, Chris Brown, Katy Perry, Michael Jackson, Eminem and many more. It is really great to have these sort of people to make music for us. Without music it would be…. boring.

Instruments make sound, and there are lots of instruments in the world like… piano, drums, guitar, violin, percussion instruments, triangle, flute, trumpet and much more. Many instruments are hard to play but some can be easy  to play.

How does music or sound travel? If you hit an object the sound bounces off  and becomes sound waves. Then, it travels into your inner ear and air drums. Finally, your brain should then recognize it as sound.
