Scientific method

Chemical change fire
Ask a question
Will it release gas?
Construct a hypothesis( make a guess)
I think the paper  burn into ashes and can not be undone.
Conduct the experiment
To do it you light the matches and burn the paper.
Record your observations and data colour change,
When we we burn the paper it release gas and also change temperature and even color.
Analyse information
We got to see the fire because gas was released and it changed into a new substance and it can’t be irrevocable.  
Report results
Today we did a chemical change with matches and paper to know that it is a chemical change it need to resales gas  and other stuff and also it can not be undone.
