Chemical Change - Fire
Ask a question
What will happen if you combine the paper and the matches?
|
Construct a hypothesis( make a guess)
I think that the paper will burn.
|
Conduct the experiment
   |
Record your observations and data: Change of colour, release of gas,
|
Analyse information

Report results
Today we conducted an experiment on paper and matches. A chemical change is something that is irreversible after being formed.Before conducting the experiment, we needed to complete the scientific method which is..
I made a guess that the paper would burn. While the experiment was held, I noticed…
As soon as the newspaper was burnt, there was a sudden change in the formula of the paper. It transformed into ashes. The temperature changed by quite a mile and there was clearly a release of gas. I believe this helped expand my knowledge in chemical change. I would also like to try more experiments to see how they are unable to be reversed.

Kia orana ALicia,
The choice of words in your table is astounding. I also noticed those things, yet I wrote up in a different way. I actually had no idea that fire was counted as a chemical change. Did you know?

I really liked how you explained what the scientific method was and how we can use it. I do a variation of this experiment quite regularly when I BBQ. As I have a charcoal BBQ I have to buy charcoal and I get it in paper bags and to start the BBQ you have to light the paper. Paper burns so well because it is made from a very flammable resource which is wood that obviously comes from a tree. Do you know what are the three components necessary for lighting a fire?
