Janise and glorias science exsoeriment

Name:Janice and Gloria

Title of experiment: Straw oboe experiment

Question:

(What do we want to find out?)

How does the straw change if you cut it smaller and smaller if it makes a higher pitched sound or, if it stays quite.

We want how it made that silly noise.

We want to know why do we have to cut it into a point.

Hypothesis:  (what do you think will happen?)

It will sound like a trumpet.

It will sound like someone farted.

It will be strang.

Sound wave will come out.

The straw will vibrate then the sound will come out through the

Procedure:

How will we find out?

(Step by step)

1. Get a straw

2. Flatten the top of the straw with your fingers

3. when you have flattened your experiment you want to cut it to the edge from your right then you want to cut from you left to make another edge.

Results:

What actually happened?

When you blow it make a funny sound. Suddenly when you cut it smaller and smaller it has more of a higher pitched sound.

Conclusions:

What did we learn?

We learnt when you blow into the straw it makes a funny annoying  

Questions:

1. What is producing the sound?

The thing that happens is that the sound makes the phenomenal

2. What pitch did we get when all holes were closed, compared to when the holes were

open?

It makes a high pitch and when it was open it makes a low pitch.

3. What does opening or closing a hole in the straw really mean in terms of vibrating an

air column?

The straw

Procedure:

4. Repeat step 2 with another straw. (DO NOT CUT HOLES IN THIS STRAW)

5. Take the pair of scissors and cut small pieces off the end of the straw while blowing as

shown in the diagram below. Repeat while cutting off more of the straw.

Questions:

What happens to the pitch as you cut off pieces of the straw? It sound like a low or high pitch. Why? Because

Maths

You need to use 2 different strategies to answer the following questions:

241 - 68 = 173

312 - 56 =256

173 - 67 =106             JANISE  RAMON DEL GLORIA ANISHA AND Allanah

56 x 5 = 280

42 x 6 = 252

40 X 6 = 240

2 X 5 = 10

4 X 10 = 40

7.0 - 3.25= 4.25

5.75 - 3.51 =1.24

9.0 - 4.73 = 5.73

6.0 - 2.56 = 4.56

Use two different strategies to answer the following questions

There are 24 ladybugs on six leaves. How many ladybugs are on each leaf?  4

To fill one jug it takes 3 litres. How many jugs can I fill with 21 litres? 7

To fill a bucket is takes 8 litres. How many buckets can I fill with 56 litres? 7

Echolocation about bats

Echolocation is a form of communication of when bats hunt and find where objects are hidden at night, bats also   communicate with other bats on how they use echolocation, this means that when you speak in a large area, or cave you can hear your own echo. Echolocation is a very special sound, this is a remarkable process of how they use their  ears instead of there eyes at night.

Echolocation is such an exceptional thing for animals because when they wake up at night which means they sleep in the daytime and that is called nocturnal. Echolocation is when bats hunt at night for food, this also helps the bats know where to go at night, because at night when they make a higher pitched sound the sound goes in front of the bat, then they become sound waves and then hit the object then back to the bat. The further away the object the softer the sound.

Echolocation is when sound waves locate the object.

Other animals like whales use echolocation and the whales use water and this is a terrific transmitter  because, the sound waves travel through the water 5 times faster in water then it does in the air.

Bats rely on their ears at night because there eyes are tiny and can not really see so thats why they rely on their ears. The bats ears are quite large compared to the size of the head.

bats don't care at night because they just think

Bats communicate by when they make sound and thats how they gather up into a group

and fly together. They stay together as they are sleeping in the daytime which is  when they are in the cave and using ultrasound which is a special sound which they use with their eyes.
