Topic: There must be a lot of scientific

There must be a lot of scientific experiments that impress you in the six years of study life. In my memory, there is a particularly interesting scientific experiment, that is, "the eruption on fire.""Volcanic eruption", everyone must have seen it on TV, but have you seen it with your own eyes? I have seen a "volcanic eruption, but this is a simulation experiment of "volcanic eruption". I also did this once in the experiment. Hey, "volcanic eruption" is really fun. I got a test according to the experiment. Glass, a bottle of vinegar and a bottle of detergent, a packet of baking soda, a newspaper. First pour some baking soda into the cup, then pour some detergent, then put the newspaper under the glass. The experiment will be immediately To start, I poured some vinegar into the cup Newport 100S, and the miracle soon appeared. Just the bottles were just some baking soda and detergent. They were divided into two parts. How did it take a few seconds to become What about the bubble? And it was just a little bit of foam. Now it��s soaring. It��s only a dozen seconds. It��s swarming from the glass mouth and overflowing the bottle to the newspaper. At this time, I��m excited again Carton Of Cigarettes. Surprised, looking at the floating foam, I was afraid of missing any details. After about 18 minutes, the bubble disappeared gradually. Ha, this experiment is so fun, it��s so interesting! What is it? I Hurry to catch The book was checked Cigarettes For Sale, but there was no mention in the book. Oh! No way, I have to ponder over it. Didn��t Teacher Liu talk about it in class: Baking soda and vinegar will react chemically and produce a lot of foam. Just like a soda, it will also produce some foam. So what does the detergent do? I can't think of it Newport Cigarettes Coupons. I have to revisit the experiment and find out the mystery. The reason why the bubble will go up is because the detergent plays a catalytic role. Isn't this similar to the formation principle of pumice? This small experiment is really interesting. I did a small experiment in science Newport Cigarettes, let me know the scientific reason in play, and exercised me. The ability to move the brain is really the best of both worlds.Through this interesting experiment, I not only let me know the reason of "volcanic eruption", but also understand that there is science everywhere in life. As long as I continue to experience the process of scientific inquiry, I will certainly acquire scientific knowledge and understand the true meaning of science.
