Burning newspaper experiment

Burning Newspaper
Ask a question
What will happen when we burn a newspaper?
Construct a hypothesis( make a guess)
I think that the newspaper that we burn will turn to ash.
Conduct the experiment
We burnt the newspaper and it turned into ash.
Record your observations and data colour change
When the experiment was happening I noticed that my hypothesis was correct when I said it would turn into ash but there was a little more to it. Its temperature also changed from room temperature to hot and the colour also changed as well, from different colours to dark and light grey. I also noticed that when it was burning it let off smoke and the smoke also had an odd smell attached to it.
Analyse information
  • There was colour change ( light grey and dark grey )
  • The temperature changed ( went hot )
  • Its irreversible ( the paper could not go back to its original form after it was burnt )
  • It let off smoke with an odd smell. ( the smoke was caused by gas in the experiment, when it burnt the smoke carried a smell with it when it evaporated into the air. ).... ( can't describe the smell )
Report results:
My hypothesis was partly correct. (  I said “The paper will turn to ash“  ) and it did
