Carbon dioxide, which consists of a carbon atom and oxygen 1 2 atoms per molecule.Formula is CO2 non-flammable and not react. Carbon dioxide can dissolve in water. Become the carbonic acid which will transform into bicarbonate and carbonate, carbon dioxide, a gas with quantity (0.038%) volume was ranked 4 in the air, the nitrogen, oxygen and argon. Experiment 1 do experiment of reaction, carbon dioxide. By the reaction between sodium bicarbonate with vinegar, baking sodaThe float higher. When there is so much gas will push balloons, inflatable out. The test gas carbon oxide which can 2 methods. Test with candles.Test 31.91 and 31.91 turbid. Caused by calcium hydroxide reacts with carbon dioxide in the air caused the sediment of calcium carbonate. Experiment 2 brought vinegar put into bags zipper lock.To make bags zip lock explosion due to the reaction between sodium bicarbonate with vinegar น้ำส้ m. Cause of carbon dioxide expanded much better. So the bag of the explosion. 3 trials when the food coloring.Put into the volcano model. Then pour the vinegar cause reactions and carbon dioxide on gas lighter than air. The rise to the crater. Just like the mountain to explode.The many styles, such as volcanic eruptions, breathing of life or การเผาไหม้ของ organic compounds. And the photosynthesis of plants. The carbon dioxide human uses such asMaking cakes, soda, soda, and used for transporting frozen foods, such as ice cream and transport
.Activities in the teaching of Science Science in elementary education from the simple activities to give students the knowledge. The understanding and the importance of carbon dioxide in living organisms.The cause of carbon dioxide, such as state conservatory, the explosion of the volcano. To create awareness of the conservation and seek protection. Prevent severe natural disasters up
