How Fire Works


1️⃣ What is fire?

  • Fire is energy we can see as heat and light.
  • It is made when three things come together.

🔺 The Fire Triangle

Fire needs 3 things to exist:

🪵 1. Fuel

  • Something that can burn
  • Example: wood, paper, candle wax

🌬️ 2. Air (Oxygen)

  • Fire needs oxygen from the air
  • Without air, fire goes out

⚡ 3. Heat

  • Heat starts the fire
  • Example: spark, hot surface, lightning

🧠 Easy line:

Fuel + Air + Heat = Fire


2️⃣ What happens when fire starts?

  • Heat makes fuel release gas
  • The gas mixes with oxygen
  • This creates flames

3️⃣ Why does fire go out?

  • Remove any one part of the triangle:
    • No fuel → fire stops
    • No air → fire stops
    • No heat → fire stops

4️⃣ Fire in nature 🌋

  • Lightning can cause forest fires
  • Volcanoes have fire (lava)
  • Early humans learned to use fire for warmth and cooking

🛑 Fire safety (important!)

  • Fire is useful but dangerous
  • Kids should never play with fire
  • Always call an adult if you see fire

🧠 Easy to remember

Three things make fire: Fuel, Air, Heat
