Science Roadshow

If you have gone to the science roadshow, then you would have seen the balloon explosion? This is how is works. With the first balloon you blow it up with your breath which is carbon dioxide. When it is blown up with air you tape a piece of paper to the balloon. Before you lite the paper you should block your ears or put earmuffs on so you do not hurt your ears. Watch the explosion and see if you like this explosion compare to the next balloon.

In the next balloon you put 100% oxygen and tie it up. Do the same with this balloon as you did with the first and watch the boom. Have you noticed the difference? Do you you know what has made the difference. The reason is because fire needs oxygen to stay in a flame.

Government boost cochlear funding

Cochlear implant

Jo Vaughans 4 year old son Dylan was born completely deaf. The government paid for the first Cochlear implant for Dylan. Dylans parents had to save $50,000 to pay for Dylan's second implant. Dylans Speech is improving and his parents are able to teach dylan how to walk. The government is now paying for both implants for children under six years old.

Eric, Rave and Nikita Funnel ears Science experiment template

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:

Hypothesis: (What do you think will happen?) e.g. I think that...
Rave: I think that the sound will get worse.  
Eric: I think that the sounds volume will go up with the funnel facing to your partner
Nikita: I think that the sound will go worse.I think that the sound
Materials needed:
A Piece of Paper, tape and tissue or cotton.
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?)

flat piece of paper
The sound was clear and didn’t make a difference.
funnel facing to the front
The sound was clear and it sounds like you turned up the volume.
funnel facing to the side
It sounds like you are inside someone else head and like you are whispering.
Tissue  blocking the narrow end of the funnel
It sounds like someone is whispering inside your head
rolled up piece of paper (facing to the front)
It sound like someone is talking to you but it sound like echoing.
rolled up piece of paper (facing to the side)
It sounds like someone is whispering to you.

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.


We have noticed that the sound is louder when it is facing in front of you. With all the experiences of the paper is turns out that it kind of makes a difference to the sound travelling to your ears. But from the different angles that we held the funnel the sound was different. Some sounds sounded like someone was whispering to or shouting to you from across the room.

Term 2 Immersion Assembly

The first day of term 2. While all of the classrooms were coming to sit down Mr J played (I like to move it, move it). After all of the classrooms was sitting down Mr Burt started to greet us back. “ This term is about science” Mr burt said.

Mr Burt said “Give it up for Team 1!” A movie started to play on the screen. The movie had a lot of safety equipment to protect the animals and us. There was a giraffe Walking into a metal box so he can get feed. The was hippos, kiwis, lions and all kind of other birds.

“Give a round of applause for Team 2” Mr Burt said. A music video popped up on the screen. There was lots of air balloons then the teachers come up on the stage. One of the teacher had a cardboard plane over her another teacher had a box on her waist with a little propeller at the end there was a teacher who was wearing a pilot suit and the last teacher was wearing a fairy suit.  The pilot through all kind of planes. Paper planes and gliding planes.

“Give a round of applause for Team 3” Mr Burt said. There was music and the team 3 teachers started to dance their way up onto the stage. They started to talk about rainbow colours and see if they can join the colours. You can join any colour to green except green. You can join any colour to black. You can not join any colour to white.

Mr Burt said “Give it up for Team 4!” A movie started to play on the screen. It had a video about flotation. There was a man who had a modal boat and he put it in a tank of water and was falling out of the tank and went in a jar. Next the man Was next to a big bowl of water and he had a piece of tape to show the height of the water and the man jumped into the bowl and he showed that the water rises.

Mr Burt said “ Its time for team 5!” The team 5 teacher started to march next to the stage with musical instruments. The teacher started to play the instruments for a little while then a movie started to play.It had the teacher play the instrument one by one and then it had them play all together. It also had the teacher play real instrument while lip syncing. They had been playing two kind instrument in the same movie.

“Give it up for Mr J” Mr Burt said. Mr J went up on the stage and started to talk about number 8 fence wire. He was saying “ You can Fisk anything with number 8 fencing wire. He asked for a boy named Lee. Mr J picked a little kid to come up and try and lift an object over his head. Lee could not lift it so Mr J grabbed a rope crane and asked the Lee to pull the rope to see if he can join the crane to the object. Mr J went behind the stage and grabbed a piece of number 8 fencing wire joined it together. Lee started to pull and he was able to lift the object over his head. Music started to play and we went back to class.

Straw Oboe Science experiment template

Science experiment:

Question: What will happen to the sound if I cut the straw shorter and blow through it?

Links to research about Sound:

Hypothesis: (What do you think will happen?) e.g. I think that….
I think the pitch will go higher and higher each time you cut it.
Materials needed:
Scissors and a drink straw
Experiment (procedure):
e.g. Step 1 -
Crease the straw 2-3 cm on one end
Step 2 -
Cut a triangle shape on creased end. blow in cut end.
Step 3 -
Listen to the sound and record
Step 4 -
Cut the straw shorter
Step 5 -
Listen to the sound and record

Data (What happened?)

Straw Length
The pitch was annoying.
The pitch went higher and more annoying.
The pitch was really high and really annoying.

When the straw was 15cm the pitch was annoying.
When the straw was 10cm the went higher and the sound got more annoying.
When the Straw was 5cm the pitch got even more higher and much more annoying.


I have noticed when you cut the straw shorter the pitch goes higher.

Sound: What can I hear

Sound is important for or environment. Without sound it is not safe. What if you could not hear and your fire alarm goes off you would not hear it and you could get burnt. Without sound you could cross a road and get hit by a car. So sound help everyone.

When at home you might hear your brother sister dad or mum could be playing a game or watching a movie so you might join in that is sound. At school you can hear the kids in your class talking and tapping. Outside you can hear people chatting and kicking balls.

You can hear cars whizzing past the road so you know when to cross the road safely. Most People do not like to listen to their brothers or sisters fighting. You might hear the tap turning on and off that might be annoying. Not being able to hear must be boring and weird because sound makes the world a much better place.
