Echolocation Explanation

Echolocation is a type of communication that certain animals use. This process is very unique and some mammals use it to help them survive, whether its in the forest or in the ocean. This explanation is going to tell you what echolocation is.

Where do the echoes go? Mammals that use echolocation basically rely on their ears, because their eyesight is not as good as their senses and hearing.  Bats are nocturnal, they sleep during the day and are awake at night time. As they fly through the air they use echolocation to help guide them. Bats have a type of noise that they make. They do this because they have poor eyesight and need to find their way around objects. When they make a sound it echos,  if that particular sound comes back to them then that means there something ahead of them.  Bats use sound to see, they also use echolocation to guide them through the forest and to avoid obstacles.

What is  echolocation, why is it used? Echolocation is a sort of transmission. This unique process is incredibly important to mammals that utilize it. There are many different reasons of why they use this type of communication. It helps them to, avoid obstacles, seek for water, catch their prey,  refrain from predators,  navigate, hunt and to interact with the environment. As Bats awake at night time the set out to hunt for food. While there out they have to keep a look out for predators. For them to figure out whether there’s something in front or around them they produce a sound.  It has to be loud enough for them to hear it, if it bounces back to them. If it does they pick up the sound with their really sensitive ears.

Try yelling in a cave and see if you can hear your echo, because that’s exactly what mammals that utilize echolocation do. If certain mammals didn't have the capability to use this very distinctive process called echolocation, it would change their lives. They wouldn’t be able to catch their prey, avoid obstacles, abstain from predators or do anything that they could do if they had that kind of ability.

Sound Explanation

This term we are learning about sound. Now what is sound, how is it created, where does it come from? Well... sound is all around us and we hear noises and sounds on a daily basis. It is a form of energy and vibrations. In space I think that there is no sound because there's gravity. I think this because if there's gravity than how are the sound waves suppose to travel.

Sound initially starts from a material or any other object that vibrates. When the material vibrates, sound waves are created. Unfortunately we cannot see sound waves but they are there. Why? Maybe because they move too fast. Sound travels through water at approximately 1,430 metres per second, which is about five-times faster than it travels through air. As they travel through the air, it hits your eardrums. The brain translates it into a sound that we recognise or know. Instead of us hearing vibrations we hear sounds, because our brain already translated that vibration into a noise that is recognisable for us. There’s a low and high pitched sound. If the sound waves are far apart then its a low pitch, but if the sound waves are close together its a high pitched sound.

How is sound created? Well.. Sound can be created in a variety of different ways. Such as when you talk, sing, when you hit something or when you make any noise you create sound. Even when a material vibrates they send vibration that travels through the air by sound waves. Sound waves start off in one spot then go out in every direction. We hear all kinds of sounds everyday, but don’t take notice of them. Especially sounds we hear on a daily base.

What does our brain do and how is it involved in this process? Our brain has a very important job which is translating vibrations into a sound. With class 3’s cup experiment it went great. Finding how this worked was really interesting. As you talk into the cup your vocals vibrate and sends that vibration through the string. As soon as its travelled to the other person you're communicating with, it goes in their eardrums and the brain does it’s job. Which is transferring it into a sound. The human brain is magnificent. Making the “Talking Cup Experiment” was really easy. The equipment needed for this is plastic cups, a pin, string and a ice block stick. First of all you need to make a hole with a pin in both cups so that the thin string can fit through. Thread the string through the hole and attach it to a ice block stick inside the cup. You need to tie the string around the ice block stick so that it won't be able to come out. After that you’re ready to have a go for yourself and see if this cup experiment does actually work.

If we had to live in absolute silence it would be totally boring. How would you hear music, or even the relaxing sound of the birds chirping away as you awake. You won’t be able to hear your Mum telling you off, but that would be marvellous. Why live in silence when you can live with hearing sounds. I couldn't imagine living without sound.

JK Rowlings Reading Activity- Shine by Makerita Urale

School Journal Story Library, Shine by Makerita Urale

WALT: Identify and understand new vocabulary we come across in a text.

Success Criteria: I can research words I am unsure of that I come across while reading the text.

Answer the following questions in red:

Who are the people involved in the group ‘Shine’? What are each of their roles in the group? Lasi Hunt- Drummer
Phillip Sipa- Rapper
Malia Wilson- Singer & Rapper
Matapa Tairea- Guitar Player
Tepa Foua- Bass guitar player
Mana Faraimo- Guitar player

What does Lasi mean when he says ‘I reckon we should go for it’? I think that he means they should try and sing and give it a go, even though they may not win.

What is a record deal? A record deal is where a musician records their music and sells it to a record label.

Define what a competition is? A competition is when you or someone competes in something, you could compete in anything such as an art competition, singing competition or even a dancing competition. Then give an example of a competition? “Come one Milly we got to compete in the dancing competition, we’ve been practising for a long time. We can’t just back out now”, said Zoe

What is a musician? A musician is someone that writes and creates music. Who are famous musicians we know? Beyonce, Nesian Mystik, Demi Lovato, Miley Cyrus, Selena Gomez, Justin Bieber, Justin Timberlake, Kelly Clarkson, Alicia Keys, Ariana Grande, Little Mix, Jonas Brothers, Titanium, One Direction

What are the group rehearsing for? They are rehearsing for the Smokefree Pacifica Beats award in the Cokesmokefreerockquest.

Why is it so important that we rehearse if we were in a band or for anything important coming up where we may be presenting in-front of an audience? It’s important to rehearse so that as soon as you get on stage you know exactly what to do and what to play. If you didn’t know any of these things you would stuff up really badly, you’d probably embarrass yourself.


Define the word region? A business place of a city or country. Then write it into a sentence of your own. The regions are held at Australia.

Would it be difficult for a group of young musical artists to write a song of their own? Yes Why/why not? Because you’ll be so busy doing heaps of other things, probably studying or working for something. You may not have enough time to even write a song.

Research all of the instruments in the band, how do each of them play sound? What vibrates that enables us to hear a noise? How does the pitch of each of these instruments change?

Guitar/ Bass guitar: You play the Guitar/ Bass guitar using your fingers. When you pluck the string it vibrates and it also depends on how you tune the string. If the string is tight then it makes a high pitched sound. If the string is a little bit loose than it makes a low pitched sound.

Drums: Like every other instrument drums are basically the same well... sort of. When you hit the drum head with the stick it pushes the head down and forms energy. The drum head then vibrates back and forth. The vibration of the drum head creates pressure waves. The harder you hit the drum head the more the drum head flexes.

A microphone: Microphones are a type of transducer- a device which converts energy from its normal form into another. Different types of microphones have different ways of producing energy but they all have one thing in common: The diaphragm. When the diaphragm vibrates, everything else in the microphone vibrates. The vibrations are then converted into a electric current, and becomes the audio signal.

Summarise what has happened in the article so far: Lasi and Philip were talking to their friends Malia, Matapa, Mana, and Tepa about entering the Smokefree Pacifica Beats competition, in the Cokesmokefreerockquest. They all make up the Porirua College band Poetic Dynasty. “When are the regional heats?”, asked Malia. “A couple of months away. We’ll have to rehearse a lot if we want to be ready for it”, says Lasi. Most of the band went to watch last years Pacifica Beats at the Wellington Town Hall. They had to write their own song for the competition. Matapa was told to play the bass and Phillip would play the drums. Each person in the band could play all sorts of different musical instruments. They swapped instruments so that it gives everyone a good feel for the new song. The band played the whole song. They were very pleased with it. The bands music teacher reminded them to always practise. They practise up to 3 times a week, but mostly during music time. Malia’s Mum and Dad have their own band, so sometimes Poetic Dynasty goes to Malia’s house to use their gear. They have a drum kit, ukulele, bass, guitar, microphones and everything they need to practise with. They’ve played at a local gig before. “Lets go down to the shops at Cannons Creek and jam for the people walking past”, Tepa suggests. “Great idea”, says Mana. The band is use to playing in front of their community and families. Most of them have grown up playing music in church.  The day of the competition arrives and they were all ready and excited, but before the band even got to the venue, Matapa dislocated his shoulder, while playing a rugby game for the first fifteen. The band rushed to the hospital. Even though they're going to be late for the competition. The doctors strapped up his shoulder with a sling. There is no way Matapa can play the guitar now.  The band then heads off to the school where the heats are being held at. In the hall everyone was waiting for Poetic Dynasty to arrive. The MC fills in and starts to entertain the audience. Then finally the van pulls up and the band members rush back-stage- all except for Matapa. Because of his injury and his sling on his arm, he has to stay in his rugby shirt. They then take their positions on stage. Philip, Malia and Matapa stand at the front of the stage. Lasi’s on drums, with Mana and Tepa on guitars. Lasi starts with the drums, and then the guitars come in. Three strong voices start singing away in harmony. They fill the hall with the words “Shine! Shine!” The crowd dance to the music and clap. When the song finished the band took a bow and walked off stage as the crowd roars and cheers in appreciation. The band gathered in a circle backstage and are relieved that its all over. Sadly they didn’t win this time, but they’re determined to keep trying. They’ve still got their eye on that recording deal.

Matapa dislocates his shoulder, how do you think the other band members are feeling about this? I think they were feeling very sad and a little bit let down because he won’t be able to play the guitar.

The band is scheduled to perform a 5 minute set - what does the word schedule mean? Schedule means what you do at a certain time or date. Also what your going to do after that.

What do we know about Matapa’s attitude after the dislocation of his shoulder? He still wants to play the guitar, but he still doesn’t perform on stage.

How do you think Poetic Dynasty did on stage after reading the text? I think they did very well indeed. They tried their hardest and did the best they could, even with one person in their band not contributing because of his injury.

Why had the group chosen to name their band ‘Poetic Dynasty’? Poetic refers to the lyrics they write, and dynasty refers to their history and culture. Research the word dynasty? What does it mean? A line of a family's heritage and history.

We know the group mainly write sound about their culture, what do you think is their reasoning for this? They probably are really proud of their culture and really love their culture a lot.

State three facts about Malia Wilson:
1. She is quite use to practising and rehearsing. She thinks that practising is very important to get your songs really tight.

2. She likes Soul and R’n’B music, sometimes she listens to heavy metal songs to just let go.

3. She sings and raps. She also helps writing the songs. She can also play guitar, bass, and drums.

Talking Through Cups

Name: Taeshell, Cheyanne, Raeleen

Title of experiment: Talking through cups

(What do we want to find out?)
We want to find out if its possible to talk through cups and still hear each other. We also want to find out if this experiment is going to work. I also want to find out how vibration works using cups, strings and an ice block stick. How are we able to hear each other.

Hypothesis:  (what do you think will happen?)
I think it that the thickest string is going to work and also the rope string. I think this because the first string may be too thin and the more space the vibrations have to travel the clearer and louder you'll hear the other person your communicating with.

How will we find out?
(Step by step)

1. First of all we need to make a hole with a pin in both cups so that the thin string can fit through

2. We need to thread the string through the hole and attach it to a ice block stick inside the cup.

3. We need to tie the string around the ice block stick so that it won't be able to come out

4. When we are finished with that string we detach that string from the ice block stick and move on to the rope string

5. For it to fit through we need to make the hole a little bit bigger.

6. Next we thread that string through the hole and tie it to the ice block stick.

7. After we've finished with it we can move onto the thickest string. So we need to take the string off the ice block sticks.

8. We'll probably need to make the hole bigger using a pin once again so that the string can fit through

9. Thread it through the hole and tie it to the ice block sticks.

10. That's how we're going to find out.

What actually happened?
1. We were able to hear through the thin string. It was allright but it could've been better. The noise level could of been louder.

2. When using the rope string it was much better then our first string, we could hear each other very clearly maybe because it was thicker. I also think that the further away the person your communicating with is. It's

3. Our last string was probably the loudest out of all of them. I think that this string was the loudest because it was the thickest out of all of them.

What did we learn? We learnt that using cups as telephones actually do work. We also learnt that the thickest string is probably the string that's going to work. Probably the closest you and the person your communicating with, you'll be able to hear them much more clearer and louder. I also learnt how vibration works when you have 2 cups, strings and an ice block stick. When you talk into the cup your vocal cords vibrate and make the bottom of the cup vibrate as well. When it vibrates the vibration travels through the string and to the other person your communicating with. Since you're listening to them with a cup and the cup covers your ears. You can hear them clearly. I think it depends on the length of your string and the thickest your string is.

Triangle Decimals

This is my triangle decimal that I've completed.

Alphabet Addition

Each number in the alphabet equals a number, here is your key.

You need to add the numbers in the words together to find your answer.

A = 1
B = 2
C = 3
D = 4
E = 5
F = 6
G = 7
H = 8
I = 9
J = 10
K = 11
L = 12
M = 13
N = 14
O = 15
P = 16
Q = 17
R = 18
S = 19
T = 20
U = 21
V = 22
W = 23
X = 24
Y = 25
Z = 26

Vibration - 22 + 9 + 2 + 18 + 1 + 20 + 9 +  15 + 14 = 110
Maths - 13 + 1 + 20 + 8 + 19= 61
Sound - 19 + 15 + 21 + 14 + 4= 73
Molecule - 13 + 15 + 12 + 5 + 3 + 21 + 12 + 5= 86
Experiment - 5 + 24 + 16 + 5 + 18 + 9 + 13 + 5 + 14 + 20=  129
Pitch - 16 + 9 + 20 + 3 + 8= 58
Transferred - 20 + 18 + 1 + 14 + 19 + 6 + 5 + 18 + 18 + 5 + 4= 128
Movement- 13 + 15 + 22 + 5 + 13 + 5 + 14 + 20 = 107

You need to add each number in these words and find out what they equal in numbers.

Jk Rowlings Reading Activity- The Right Beat by Ken Benn

The Right Beat by Ken Benn

Connected 3, 2005.

WALT: Read the text to extract greater meaning which we will display in our follow up activities.

Success Criteria: I can read the text to extract greater meaning which we will display in our follow up activities.

Answer the following questions in red:

Referring to the images and title of the story what do you think this text is about? I think that it’s about singing and a band.

Simon is the producer of Feilding, what would his job entail? He helps to make sure everyones doing what they need to do and he is in charge of it.

Who is the fundraiser for? For people affected by the recent floods

What will be done with the money generated from the fundraiser? It will be given to the people that have been affected by the floods.

What is Shona’s problem? She thinks that the tune is not right

Why is it important to sing in tune? Because if you don’t sing in tune you get it all wrong and everything goes out of time. (do your own research)

What lasts for two beats? An open circle with a stem, lasts 2 beats

What lasts four beats? The big circle note without a stem, the semibreve, lasts 4 beats.

What would happen if they double the tempo? The dance would be totally frantic if they made the tempo any faster. What is the tempo? Its the type of speed that the music should be played at.

Why is it important for the drummer to know about bounce? It’s important for the drummer to know about bounce because when it comes to drumming they need to keep the beat in place for all the other instruments or people to do their thing. They also need to know about bounce because they’re the drummer, there the ones that create the beat for everyone to join in.


Why is it important to understand the rhythm when taking part in music? It’s important to understand the rhythm because if you don’t you won’t know what tune to sing at or what pitch. You won’t know what note to play if you’re playing an instrument.

Summarise what has happened in the story so far. Simon (the producer) was putting together a great show for the people that have been affected from the recent flood. But Simon says that Shona’s words aren’t that great. Shona disagrees with Simon and says that the problem is the tune. But things just got worst because a news crew will be filming them for 30 seconds and putting it on for national t.v. Simon also wants the dancers to be in scenes as well, so it has to be something they can move to. “It’s your words Shona. There’s too many of them”, says Ben. Simon looked at Shona’s lyrics again. He liked the words but it takes 65 seconds to sing the whole thing in Bens tune. He knows just a little about music but he tried to understand what the problem was. Simon knew that each of the notes shows by an open circle with a stem (the minims) lasts for 2 of the beats. That means 2 full dance steps. The big circle note without a stem, the semibreve, lasts 4 beats. Moniques the lead dancer and thinks that it might just help if they played this tune at double speed. Monique placed her hands on her hips and said “We make one movement per beat, so the dance would be totally frantic if you made the tempo any faster. “Sorry Simon, it’s the tune that’s the problem. It’s got no bounce”. Ben (the drummer) was a little bit startled and said “ No bounce!, what does she mean no bounce”. Simon passed Ben a piece of paper and a pen and mumble “You understand rhythms better than I do, Ben”. “ Your music is made up of only 2-beat and 4-beat notes”. They tried so hard to figure out how to make it shorter without ruining it and finally they found it. Kiwa was listening to the argument with amusement. He has written his own music before and knows about the time limits and dancers. “Try writing the tune in crotchets”, he suggests. Kiwa then explained how he could make the timing right by adding in and taking out things. “Your tune is cool Ben. But we need to flash it up a little. If we change the rhythm, we can leave the beat the same, That way the dancers won’t have to move any faster”. “Whatever”, Ben mumbles. Shona sang with with a big smile spread across her face but the timing was 33 seconds, which was still too long. They needed it to be 30 seconds. “We still need to lose another 3 seconds, I know what we can do”, says Kiwa. A quaver is halve a crotchet. “We need 30 seconds of music. At 2 beats a second, that’s 60 beats. So with 4 beats in a bar, we need 60 divided by 4 which equals 15 bars of music at the most!” “I think we’ve got it,” Ben says to Kiwa. Feilding Idol was a great success. The dancers did their moves and Shona was pleased to hear that all her lyrics will be used in the news clip. Simon was relieved and said a special thanks to Ben and Kiwa. He decided to frame the music for them- in three versions.

Describe and analyse the image and labels on page 27. What does each title referring to the musical bars refer to?
Minim- lasts half as long as the normal semibreve, you’re able to fit 2 beats in a bar
Quaver- lasts half as long as a crotchet, you can fit 8 beats in a bar.
Semibreve- The longest note in a bar is called a semibreve. It lasts for the whole bar.
Crochet- lasts half as long as a minim, you’ll be able to fit 4 of them in a bar

Kiwa has been listening to the argument with amusement, what does amusement mean? When you find something funny or when you find something entertaining. For example- Amusement filled the room as bill held up his artwork.

Put amusement into a sentence of your own. Amusement filled the room as bill held up his artwork, which was a portrait of himself.

What is Kiwas idea that will solve the issue? Writing the tunes in crotchets.

The ratio of crochets to minims to semibreves is 4:2:1. What does this mean? I think that this means there are 4 crotchets, 2 minims and 1 semibreve.

Define the word ratio? The relation between two amounts, how much is in one of them and how much is in the other one.

Put ratio into a sentence. The ratio between girls clothes and boys is 8 to 1.


What is a hasty decision? A hasty decision is when you react or make a decision quick. Simon says “let’s not make any hasty decisions, what does he mean by this? I think he means “lets not make any quick decisions”.

Why would knowledge of maths be important as a musician? Refer to the text on page 31. So that the musician can understand how many beats there are and all of that stuff.

How was Feilding Idol a great success in the end? They managed to get the show done and dusted and all the dancers got to do their thing. Shona was pleased to hear that all her lyrics will be used in the news clip.
