What are combustion reactions?

Combustion reactions are when things burn because they meet up with oxygen and heat.

Imagine you have a matchstick, it’s like a tiny hero that loves to fight fire. When you strike it, it starts burning. That’s a combustion reaction: the matchstick meets oxygen in the air and some heat, and poof! It lights up.

Most things that burn are made of fuel, like wood, paper, or even your favorite snack (pretzels count!). When you light a candle, the wax is the fuel. The flame happens because the wax meets oxygen, and the heat from the flame keeps it going.

Think of it like a party:

• The fuel is the guest.
• The oxygen is the host who brings the energy.
• The heat is the music that gets everyone dancing.

When they all come together, boom! You get fire, and sometimes smoke or sparks too.

So next time you light a candle or roast marshmallows, remember: it’s just a friendly party between fuel, oxygen, and heat!
