Echolocation : Explanation
Introduction
Echolocation is a unique process of sound that is repeatedly used mainly by many animals to help to avoid/detect danger,obstacles or food/water. Animals such as bats, marine mammals, rodents even humans.
Body:
A bat is a perfect example of echolocation. When a bat travel through pitch-black caves, they use echolocation. Bats sends vibrating signals which can either bounce back to the bat or carries on until they reach an object then bounce back. If the vibrations bounce back fast that means there are objects ahead so they avoid it but if it doesn’t come back until it reaches a nearby object the bat goes ahead until they reach that objects. Bats also use echolocation to hunt insects or food. Bats use their ears as eyes. They send the same vibrating signals which bounces of an insect then back which tells the bat thats its a prey. Echolocation helps humans too. They use ultrasound to check if a baby in the mothers stomach and to detect animals in seas and rivers.
Conclusion:
Try yelling in a cave can you hear your echo. The vibration of your vocal cord vibrated throughout the cave then back to your ears where the brain translates it back into sound. Many animals rely on their ears instead of their eyes.

Sound Explanation
Introduction :
Sound is everywhere around us. Even when you're in a silent room you can still hear yourself breathing or your heart pumping.
Body :
Sound is vibration. If an object is hit, it begins to vibrate. These vibrations travel through sound waves. The closer the sound waves the higher the pitch, further away sound waves gives you a lower pitch. Also sound can travel four times faster in water than air. Just think about ripples in a pond. When you throw a pebble into the pond, it creates ripples. Just like sound, It vibrates then fades and it shows you an example of what these vibrations may look like. Why we hear sound is because these sound waves travel through your ears then into your brain where your brain translates it into words/sound. Did you know? In space there is no sound. The reason behind this is that vibrations need something to travel through. In earth the vibrations can travel through air or water. In space though, There is no mediums so the vibrations cannot travel and make sound. So without water or air there is no sound.
Conclusion :
A world without sound would be so tough. Sound boosts our chance of survival and communication. Sound can help animals hunt their food and help detect danger. Animals would become extinct fast and humans wouldn’t have meat to eat.

Alphabet Addition : Term 2 ; Week 2
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 + 1 + 15 + 14 = 102
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= 56
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.
102 + 61 + 73 + 86 + 129 + 56 + 128 + 107= 742
Reading : The Right Beat
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?
It looks like there doing maybe a play or a singing show but can’t actually get the right beat for the song.
Simon is the producer of Feilding, what would his job entail?
He puts the show together and he is like the boss he gets to tell other people what to do
Who is the fundraiser for?
The fundraiser is for people who has been affected by recent floods.
What will be done with the money generated from the fundraiser?
It will be donated to help maybe rebuild or build new buildings
What is Shona’s problem?
Shonas out of tune. In the text ; “ Simon likes the text , but it takes 65 seconds to sing it to Ben’s tune.”
Why is it important to sing in tune? (do your own research)
It is important to sing in tune because there doing a fundraiser and if its out of tune then they probably won’t raise anything or noone will listen.
What lasts for two beats?
A minim: Simon knows that each of the notes shown by an open circle with a stem ( the minim ) lasts for 2 beats.
What lasts four beats?
The semibreve : On the other hand, the big circle note without a stem, the semibreve lasts 4 beats.
What would happen if they double the tempo? What is the tempo? (do some of your own research?
The tempo is the rate or speed of motion or activity. If they doubled the tempo it will be quite fast and the song won’t be 65 seconds but 30 seconds and the dancers would have to do one movement per beat, so the dance would be totally frantic if he made the tempo faster.
Why is it important for the drummer to know about bounce?
so when the dancers come they don’t have to dance faster to catch up to Ben's beat.
Wednesday:
Why is it important to understand the rhythm when taking part in music?
Without rhythm, humans would have no sense
of patterns, and music would simply sound like nonintegrated noises of nonsense
Summarise what has happened in the story so far.
So a bunch of high school kids put together a fun show and raise a few money to rebuild/build new buildings for those who’s been affected by the recent floods but things became very complicated. Somehow their song isn’t sounding right maybe its too fast maybe the beats wrong or maybe their out of tune. Something horribly went wrong that caused an inconvenience to the producer and the dancers. What would they do ? Will the fun show go on ? Will they sound bad and look bad on stage ?
Describe and analyse the image and labels on page 27. What does each title referring to the musical bars refer to?
Semibreve : The longest note in a 4/4 bar is a semi breve. It lasts for the whole beat.
A minim : A minim lasts half as long as a semibreve, so you can fit two of them in a bar.
A minim : A minim lasts half as long as a semibreve, so you can fit two of them in a bar.
Kiwa has been listening to the argument with amusement, what does amusement mean?
Amusement means the state of experience of finding something funny.
Put amusement into a sentence of your own..
I went to an amusement park in the holidays.
What is Kiwas idea that will solve the issue?
In the text; At the moment, we’ve got 16.5 bars of music to play in four beats in each. SO that means we’re playing 4x16.5 = 66 beats, and at 3 beats a second , that gives us 66 divided by 2 = 33 seconds.
The ratio of crochets to minims to semibreves is 4:2:1. What does this mean?
It is timing, The crochets takes the longest and the minims takes the second longest and the semibreves takes the shortest.
Define the word ratio? (You may research this)
The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Put ratio into a sentence.
During the Vietnam war, it took like 500,000 rounds to kill or injure just 10 Vietcong: a total hit ratio of 50,000:1.
Friday:
What is a hasty decision? Simon says “let’s not make any hasty decisions, what does he mean by this?
Not to make a bad decision that could embarrass themselves
Why would knowledge of maths be important as a musician? Refer to the text on page 31.
They to multiply, add and divide the ratios and the beats of the song.
How was Feilding Idol a great success in the end?
The dancers do their thing with flair, and Shona is pleased to hear that all her lyrics will be used in the news clip.
