Here are the candle Q's

Cheer Erin

For candle to burn you need a wick, wax, oxygen to breathe and matches.
The wax turns into a liquid and sits at the top of the tin. This is called melting when it comes from a solid to a liquid.
The wick gets black and the wax starts to melt at the top and makes a pool of wax.
When only the wick is burning the gas from the wick becomes carbon dioxide and goes into the air. The wick burns all the way till the end quickly.
If only the wax was lit the wax wouldn’t burn because it has not got a wick.
If you a put a jar over the top of a light candle, the jar blocks the oxygen that the candle needs to stay a light. Also the size of the jar actually gives more oxygen to the candle. If you have a larger jar it holds more oxygen for the candle but if you have a smaller jar it doesn’t hold as much air.

Here are some photos from the candle burning at the end of the photos you will see i have a match stick standing up in dry wax that was originally liquid.

Hi Everyone,
What happened when I changed the size of the jar?
The smaller the jar the less seconds the candle did burn for.
Why did this happen?
The flame from the candle burned up all the oxygen in the jar and turned it into carbon dioxide. The candle went out because there was no oxygen left to keep it burning.
Was my prediction accurate?
Yes it was as the jars ran out of oxygen and the candle went out. The bigger the jar the more oxygen and the longer the candle burned for.

Tania 18

Hi Everyone,
Here is an idea I had when I wonderd what happend to the candle in the jar.
I have an idea why the candle goes out. The jar has oxygen, a candle needs oxygen to be able to burn. It is a bit like a human. When the oxygen in the jar has been burnt up into carbon dioxide it causes the candle to blow out.
Cheers Tania

Hi Everyone.
How are you all??
What do you need for a candle to burn?
You need matches and a wick.
Where does the wax go when the candle is burning?
It either melts to a liquid or it becomes a gas.
What happens when a candle is burning?
When the candle is burning it becomes a liquid, but it doesn’t stay that way for long.
What happens when only a wick is lit?
The wick just burns.
What happens if only wax is lit?
Well if the wax was lit with out a wick the wax would not light.
What happens if you put a jar over the lighted candle?
The candle won’t last long in a gar.

Hi Everyone, I decided to do another experiment. This time I used 3 teaspoons of bicarb soda and 3 teaspoons of tartaric acid. Also with 1 cup of vinegar and a bit of red dye. The bicarb soda and tartaric acid reacted with the vinegar making it fizz and there were lots of bubbles. The gas that was created from the bubbles floated into the balloon causing it to grow. I think the balloon was larger this time because the extra bicarb soda and tartaric acid caused more energy so this caused more gas. The extra gas had to go somewhere, so it went inside the balloon.


Cheers Tania

Here are some of the things i am learning that i have written on the window. Cheers Erin

Tania 15

Hi Everyone, How are you all? Here is a video of a vinegar experiment. The balloon became larger than when I did the experiment using water. The reason I think this happened is because the chemical reaction between the bicarbonate soda, tartaric acid and vinegar was far greater than the bicarbonate soda, tartaric acid and water. This then created energy called bubbles which made more gas. The gas went into the balloon and blew it up bigger. The fizzing went on for sometime. Cheers Tania

Dear M.S.I. detectives
I did the salt dissolving experiment.

Did you know salt molecules actually attach to the water molecules as when they dissolve?

Did you know that in the war you weren't allowed to fight in the war if you worked in a salt mine? Because salt was very important back then.

Did you know there are tiny amounts of gold in sea water? Sadly, we can't get it. Darn!

How cool is that?!

Hi everyone,
Here are some photos of my fizzing experiment.
The tartaric acid, bicarbonate soda and water had the best reaction.
We also found out that if you mix lemon juice and bicarbonate soda it reacts as well.
So if you have some at home give it a try!

Hi everyryone.
I have a question..
Why if you put salt on ice does it melt quicker???
From William.

Mitchell 11

Dear M.S.I. detectives
Hear are the pictures of the fizzy experiment.
The first bottle had no water in it to re-act with the bicarb and acid poured into it.

The bicarb in the second bottle just dissolved in the water.

The acid in bottle three only dissolved in the water.

The bicarb, acid and water in bottle four re-acted with each other. It fizzed and caused lots of carbon dioxide gas bubbles, which blew up the balloon.

Dear M.S.I detectives
This is my video demonstration of particles in a solid, liquid and gas.

Solids are when particles are compact and have a hard structure.
They can only vibrate.

Liquid particles have more energy and so can move around more.

Gases have even more energy and fill up the space they are confined in.

Energy is given to the particles by heat.

Hi Everyone
i noticed when i did my melting of ice i saw steam coming out and the water was sizzling like crazy when i tipped the sauce pan like crazy.
does anyone know why this happens?

Hi everyone
Here is a picture I drew of solid,liquid and gas. My video of solid ,liquid and gas will be up this afternoon or tomorrow.

Erin 16

Here is an lesson i had to do about gases and liquids and solids

Solids
Solids can be soft or hard. They need someone to change their shape they can’t change it themselves. Solid particles can’t move as freely as liquid or gas it just vibrates.
Changing Solids
Changing solids have different materials which means they melt at different room temperatures, that is called The Melting Point.




Liquids
When you pour a liquid into a container the liquid does not just float it goes to the bottom of the container. The reason why is because the gravity pulls the liquid down to the bottom of the container. Liquid particles can move more freely then solid but not as much as gas.
Gases
The gas gets it’s weight from the gravity. Gas particles can move more freely around then the liquid and solid.

Cheers Erin

Hi everyone
I have a question
How many particles in one solid?

Erin 15

Here is a site that you will find lots of info about gases,liquids and solids

Lori 13

Hi Everyone
here is some information on solids, liquid and gases.
Solids, liquids and gases
i used my own words

Solids:
A solid is a substance that cannot be compressed. It does not flow when it is at a given temperature. Solids keep shape to make things easier in a person’s life like being able to sit down after a long days work and being able to eat at the table.

Liquids:
Liquid is a substance that flows and cannot be compressed. A liquid does not stay in shape for long. Liquids can be in any thickness or colour.

Gases:
Gases flow like liquid and can be any shape or size. Every time we breathe in we are bringing in millions of particles into our body. I think it is kind of scary because we breathe in millions of particles.


Gases, liquids and solids:
All these substances are very tiny and cannot be seen through a microscope. In the air particles are all around us but you just can’t see them.

Hi everyone

I like to collect things on my holidays, so on my last one i collected lots of shells, but some are strange. I have some questions about them.
For shell 4, how do you guys think the white shell got attached to the orange shell?
Shell 3 is a side view of my favorite thing i found while looking for shells. I like to think it might be something a starfish died on, but i really have no idea. The circles in between the points are bubbles. What do you think it is?
Shell 2 is a piece of something attached to a shell. What do you think it is and how do you think it got attached.
Shell 1 is an interesting shell. Do you think the spikes on it were formed when the shell was formed? Or did they somehow grow there?
I have no idea what the answers for all these questions are anyway.
I think these are all change questions.
Have a nice day! ;P
