Hypothesis: (What do you think will happen?) e.g. I think that the shorter you cut the straw the higher the sound gets.

Materials needed:

All you need is a straw and scissors.

Experiment (procedure):

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

Step 2 -  Cut a triangle shape at the end of the straw and blow into cut end.

Step 3 - Listen to the sound it makes.

Step 4 - Cut the straw shorter.

Step 5 - Blow on cut end.

Data (What happened?)

Straw Length:	Results:
Long - 15 cm	Makes a Sound
Shorter - 10 cm	Sound was higher
Short - 5 cm	Sound was more high pitched.

Record:

I Cut the Straw shorter and it was high not low.  

I Cut it a bit shorter and it was a bit higher than before.

I Cut it even shorter and it was higher than the other ones I have blown.

Observations:  

When you cut the straw shorter the sound of the straw when you blow it gets higher. When it is long the sound was low but when I cut the straw down the noise was higher. At 15 cm it made a sound. At 10 cm the sound a bit higher. But at 5 cm the noise was high pitched.

Conclusion:

It turns out that my hypothesis was right. I have noticed that when you cut the straw shorter the higher the sound gets when you blow it.

Sound: What Can I Hear?

Having ears are great! Not having ears you wouldn’t be able to hear a single thing. Imagine, if you couldn’t hear anything? It will be boring and weird. If you couldn’t hear you wouldn’t be able to listen to conversations that your family and friends will be having.

Being able to hear sound is really important. At home I like listening  to the sounds of my family laughing and getting to know each other more because it is funny. Sometimes I can hear the sound of the dishes being washed or the vacuum sucking up all of the dust thats on the ground.

There are many sounds in the environment. At school I can hear the sounds of the teachers having conversations with groups and people laughing and typing on there netbooks. Sometimes I even hear the sound of visitors walking past us and watching our work.

Outside and being able to hear noises around you is good for people.  When I am outside I like listening to the sounds of netball balls being bounced. Or rugby balls being kicked. But mostly I like it when my friends and I are chatting with each other.

Whenever I am on the street and listening to things I can hear the sounds of cars whizzing past me. Not only that, I can hear the sounds of the buzzers at shops when people leave. I also can hear the sounds of police car firetrucks sirens.

My ears are great! I am glad that there is sound and I can hear. Not being able to hear will be a nightmare to me because at home I am a pretty loud person :) WIthout my ears I will be hearing nothing and I will just hear silence. It will be totally boring and creepy.

Immersion Assembly: Term 2 2014.

Wow! We just arrived back at school and it is a whole new term. It is Term 2 and people are really pumped, I know I am. Normally, in the morning we just get started with our work but not today. We had Immersion Assembly. The theme this year is ‘I like to move it move it’.

To be honest I really like that theme because I like the song ‘I like to move it move’.

If you don’t know what Immersion Assembly is well, it is when the school teachers do a performance to show the school what they’re topic is for the whole term. The first team that was up was, Team 1. There topic was all about the zoo and the safety equipment that they use.

The second team that was up was, team 2. There topic this term is all about Flight. For examples airplanes, thrust, drag and gravity. The teachers were wearing great costumes. Mrs Eddie was wearing a plane, Mrs Glaze was pretending to fly a helicopter and another teacher was pretending to be a air balloon.

The third team was of course, team 3. There topic is all about light and how it works. On stage the teachers were showing the colours of light and the speed of it. All the teachers were wearing tutus and that was the light on them. Next after team 3 was, team 4. There topic is all about Floating & Sinking. On stage they were playing a video and it was all about the displacing of water when a boat floats on it.

The last team was, Team 5 (My Team). Our topic is all about Sound and Voluming. We are learning about how sound is made, how it travels and how we hear it and Physics etc. I also hope we are going to be doing some fun experiences along the way.

At Immersion Assembly I thought it was very interesting and entertaining. I really enjoyed the performance’s. My favourite one was team 4. When they were asking questions and it was funny.

Only 2 Days Left.

Nooooooo Only 2 days left on holiday and I feel sad. I want it to continue but sadly I have to go back to school. Normally, I feel happy going back to school but not now. I just want at least one more week on holiday :) Right now I wish I was in my Mum and Dad's shoes right now.

During the holidays I got a new baby cousin, Caleb. He was unexpected the day he was born but it was a great surprise. That was my holiday highlight. He is so cute thought. Sadly I don't have a photo but I will post one soon.

At My Uncle and Aunties House.

Right now I am at my Auntie and Uncle's house playing on the computer. What do you think i am playing you ask well, I am writing this post. I am also listening to music and playing games, but in the background I can here the sounds of people laughing and my brother and cousin playing around. I am by myself right now because my cousin's (Devon and Austin) went out and went to go pick up our food to eat. I am looking forward to when they get here, so then I can eat :) Later I might be playing around with my cousin's or playing on the computer still. But I might go home later so I don't know?

Benji Marshell Going Back To NRL.

Did you know that Benji Marshell is not going to play rugby anymore. It turns out that Benji is going to be going back to NRL and might be playing for the Sharks. I am not a really big Benji Marshell fan but I think he should continue on playing Rugby. He just started and he is going to be playing NRL now. What? I think that Benji Marshell should not play any NRL and Rugby to be honest. And I think he should play for another team if he is going to play NRL. He shouldn't play for the Sharks, he should play for the Vodafone Warriors or the Melbourne Storm not the Sharks.

P.S - NRL stands for National Rugby League, I Think.

Hunting For Easter Eggs.

On the Easter Weekend I got to go on 2 Easter Egg Hunts with my family. The First one I had was at my Aunty's house. I got to Find some clues to hunt for the eggs and I had to cooperate with my buddy. Yes, I had a buddy. We went around the house and tried to find some Easter Eggs so we could eat them. It wasn't a competition but the first one to find all the clues got a HUGE egg that we got to keep and eat of course. But it wasn't fair for the other kids so they got a HUGE egg as well,  including me.

The Second Easter Egg hunt was at a Birthday. The birthday was for Nicole's daughter, Olivia. If you are wondering who is Nicole, she is my aunty's friend. We got to go on a Easter egg hunt and were allowed to just go around the house and find as many eggs that we could find and but in our bag. I had the biggest bag out of my cousin's and when I got home I ate half of them :).

I really enjoyed my Easter Weekend. Next year my aunty is planning something more exciting so I am looking forward to that. I was also glad that I got invited to a birthday party and my cousin's came with, and that was also excited and fun at the same time.

P.S - My Favourite chocolate brand is Cadbury.
