SCIENCE PRACTICE BASIC PRINCIPLES EXTINGUISH FIRES

What did you feel when the practice of science in it comes to physics, chemistry and biology, we can do with fun by using simple tools and materials. This time, ok we will practice the principle of a simple fire.

Title Practice : How to put out fires

Destination : Know about the basic principles of fire

Tools and materials:
1. Vinegar
2. Baking soda
3. 1 piece glass
4. 1 piece plastic glasses
5. 1 piece of wax
6. Matches (fire box)


Step work:
1. Keep candles in glass cups.
2. Light a candle in the glass is standing upright.
3. Combine 3 tablespoons vinegar and 1 teaspoon of baking soda into plastic cups
4. Put plastic cups into the burning candle
5.View changes

Conclusion:
What we just did is the basic principle of putting out fires. When vinegar and baking soda mix and cause a chemical reaction, in fact we have made carbon dioxide. You need to know, basically fire needs oxygen, so when the fire starved of oxygen so the flame will slowly die.
