Fire Experiment

A few days ago we did a fire experiment. We lit different things on fire and took notes on interesting things each one did. We lit a tea candle, an acorn, a piece of paper, a corn husk, a strand of hair, and cotton fabric.





Data


Tea candle:
  • Fire color is blue on the bottom
  • Fire color is orange on the top
  • When moved, flame moves other way

Acorn:

  • Smokes
  • Smells like burnt wood
  • Did not catch on fire easily

Paper:
  • Turns brown
  • Curls
  • Smokes
  • Smells like roasted marshmellows


Corn husk:

  • Burned quickly
  • Curled
  • Twisted
  • Didn't stay lit for very long
Hair:
  • Sparks
  • Burns really fast

Cotton fabric:

  • Left yellow residue
  • Burns quickly
  • Turns see-through
We also did two more experiments. One was seeing what would happen whe we put a tea candle on a plate with a jar over it, and another with water on the plate.

Data

When the candle is under a jar it snuffs out the oxygen, since fire needs oxygen, the flame goes out. It takes about 15 seconds.

When there is water on the plate, the jar acts like a vaccuum and sucks up all of the water as the flame goes out.
