Lab: Creating Carbon Dioxide

In a lab, we mixed vinegar and baking soda to make carbon dioxide. Before we mixed the vinegar and the baking soda, we lit a candle. You might be thinking, why did you light a candle? Well, to answer your question, when baking soda and vinegar is mixed, it creates carbon dioxide and also a chemical change. When you pour the carbon dioxide over a flame, it makes the flame go out. An interesting fact is that, if you are putting a candle fire out, you only need a small amount of baking soda mixed with some vinegar to make the candle fire go out. Since, fire needs energy to get larger, carbon dioxide actually helps get the fire put out, not helping the fire enlarge, which is another fact that intrigued me. It is cool that we made carbon dioxide, which is what is in a fire extinguisher and now if there is a fire, I know how to put it out, (without using a fire extinguisher). A fact that I liked was that carbon dioxide prevents energy from enlarging a fire, by putting a blanket or force field around the fire, making it go out.The part that caught my attention, was that there are many ways to make carbon dioxide, besides vinegar and baking soda. For example, if you put dry ice in water, it would create carbon dioxide and also a fog. I think that doing fun labs in class helps students learn. Making a fire extinguisher, (carbon dioxide), was one of the most fun things I have done in class so far. It is cool to do things, like this lab, in this class that we wouldn't do in other classes or outside of school. I am looking forward to doing more exciting labs like this one in the future. In conclusion, when mixing baking soda and vinegar, you get a fire extinguisher, carbon dioxide.
