Answer: experiment: to create fire oxygen is required

For this what u have to do is, taka a candle, match box and a glass according to the length of the candle,
1. Light the candle, the fire will be created by using oxygen present in the air,
2. then close the candle using the glass, u can find that there will be no flame inside,

from this we can conclude that oxygen is required to burn or to creat fire

good luck
