What is fire?
Our dear kids, some times you may be tempted to play with a fire, a fire is a chemical reaction that converts a fuel in to heat and light in the comment section below.

Fire has a lot of uses.

• The heat it makes can keep the place warm
• Fire is used to cook our food
• The heat from fire make water safe for drinking when we boil it.
• We use fire to dispose some waste.
• a fire can help us keep off wild animals from getting close.

Fire can be dangerous

• Fire can get out of control and burn down useful things and even our home.
• You may suffer some serious burns from a fire.
• The heat from a fire can make things very hot and such hot things can also burn us an example is hot water or a hot pot.

Some facts about fire

Understanding some facts about fire can help us control it.
Fire needs a fuel
For a fire to burn, it needs a fuel, this is any thing that can be consumed by the fire to keep it burning. All fires need a fuel, to keep a fire burning, you will have to supply it with fuel, but if the fire is to be stoped, identify the fuel it is using and stop its supply.
Examples of fuel are: dry wood and things made of wood, paper books documents, clothes, kerosene, petrol, cooking Gas, oil, candle wax, plastic materials,
Without this materials, a fire will get extinguished.

Fire needs heat
Fire needs heat to keep burning, when the temperature of a fuel increase it becomes easy for it to burn, if a fire is getting out of control, removing the heat can help manage the fire. water has been used in many instances to stop a fire. The water takes away the heat and the fire goes out. This is because wet surfaces do not easily heat up.

Fire needs Air
Besides a rich supply of fuel which may be one type or a combination of different fuels, a fire also needs heat and air to burn. This three components are needed together for a fire to continue burning, taking away one of these three will result in the fire going out. While air is a mixture of gases including Oxygen, Nitrogen, Carbon dioxide and others. In this mix of gases that makes up air, it is oxygen that makes fires keep burning.
Some fire extinguisher are good at taking away the oxygen to kill the fire. But how are we sure that air is needed for a fire to burn.

Let's perform an experiment

Experiment to show that air is needed for a fire to keep burning.
Materials
For this experiment, we need the following materials:
• A candle
• A matches
• A sourcer
• Some water
• A glass
• Note taking materials
• A watch

The candle

This will be the source of a sustainable fire, a fire that can burn on its own if not disturbed.

The matches

This will be used to start up the fire

Small plate

This small plate will help hold the candle and the water.

The water

The water will make sure no air gets into the glass.

Procedure

• Cut the candle to a size that is a third of the size of drinking glass you will use.
• light up the candle and place it in the small plate
• Pour some water on the plate and observe the setup for 5 to 10 minutes

• Now use the glass to cover the candle

Observation
As the flame feeds on the oxygen in the glass, the flame gradually dies out as it runs out of oxygen,

The consumed oxygen create some vacuum in the glass. Because the water will not allow for a fresh supply of air/oxygen, attempting to suck in a new supply of air will only result in water being sucked into the glass.

Precaution

• This experiment should only be performed with adult supervision.
• The candle must be cut so it fits well in the glass with the wig and flame put in to consideration
• Be careful not to get burnt by the flame
• This should be done in an environment with good lighting

Conclusion

For the candle to go off in less than 10 seconds after being covered with a glass shows that it needed air to thrive, if the glass is immediately lifted when the flame starts to die out, it gets rejuvenated and glows again when new air is sucked into the setup.

Which means that a fire really needs Air(oxygen) to keep burning. And that is why we have vent holes on lanterns

Experience

I have seen a woman who's oil cought fire and she stoped the fire by covering the burning pot of oil with a very large pot.
The fire in the oil quickly died out when it ran out of air.
