Awakening Millennium

　　 "Then what happened to you just now?"

　　Xiao Jing doesn't seem to believe it yet. It seems to be in her heart. If there is something wrong with her sister, shouldn't she say something? But Levi's impression was that when the four girlfriends were together, Xiao Si was also very active. Today it is estimated that because of the addition of these three school girls, Feit makes Xiaosi a little embarrassed, so he always looks dumb. In fact, this girl is not just a little bit natural, it is not the kind of nothing that Nagato has.

"I just want to ask, why do you make ice cream with salt? What did you just hear from Miyuki? Doesn't salt melt snow and ice? In that case, adding salt would make it harder to turn milk and cream into ice cream. ?"

　　Two of the three school girls are missing, and the pressure of Xiaosi seems to be reduced. Or maybe she got used to it a little bit longer. In fact, because of this side, the sisters of the Zeng family and Gao Liangmei had some contact with the girls who transferred to the No. 2 middle school this time. It's just that the time for girls to enter school is short, and everyone hasn't known for a long time. I believe that the next semester will begin another period of time, and friends here will gradually become familiar with the girls of the Levi family.

　　 "It turns out that this is true, Xiao Si is actually right. If you put the salt directly in the iron bucket, it may be difficult to make ice cream."

　　 Meixing is worthy of being a natural teacher. When he heard the questions from Lei, Levi could feel that this girl who was always light and flirty seemed to be more happy.

　　 "In fact, the reason why the salt can melt snow and ice is mainly because the salt melts into the snow water, so that the temperature required for solidification becomes lower."

　　 This simple explanation, of course, Xiao Si can't understand, and the expression of aggression makes Levi want to laugh.

"In general, the freezing point of water is zero degrees Celsius, that is, water with a temperature below zero degrees Celsius will freeze. The freezing point of brine, that is, sodium chloride solution is lower than zero degrees, generally below ten degrees Celsius. Yes. Among the chloride salt snow melting agents, there are lower freezing points. For example, the freezing point of calcium chloride is -20 degrees below zero, and the temperature of acetate drops below -30 degrees before freezing. ."

　　Although I still don't understand what salt can make ice cream. However, those knowledgeable divisions that Gao Liangmei Xing said understood. After all, she was also a student who was able to pass a good high school grade on her own. If she can't understand even that simple scientific knowledge, it really makes people worry about how she usually completes her homework every day.

"The reason why putting salt on ice or snow can help to make ice cream. In fact, it uses the lower freezing point of the chloride salt snowmelting agent, which is equivalent to reducing the temperature of ice and snow. The lower the temperature, the iron The ingredients in the bucket can solidify more quickly. For example, some refrigerators in the refrigerator of the home can reach minus 20 degrees Celsius. Such a temperature is obviously much lower than the temperature we can get at this ski resort. That is to say, use the refrigerator to store the water. The speed of freezing into ice is definitely faster than putting it on the ski **** in the open air. The same is true for making ice cream."

　　 "The original role of salt is to lower the temperature!"

　　Miyuki spoke clearly and clearly, and Xiaosi heard it immediately. Looking at her nodding frequently, people are curious about her sister Xiaojing's ability to teach others. Everyone often listens to Xiao Jing complaining that when Xiao Si asks himself at home about something he does not understand in his homework, it takes him a long time to barely teach her. However, now observing the process of Miyuki explaining to her, it makes people feel that Xiaosi's understanding ability is not as bad as Xiaojing complained about.

So in the end, it is Xiaosi who is more serious, just like Naye. She understands the content of these sciences better, but the liberal arts always do not understand, so let Xiaojing say that it is not consistent with everyone’s perception. Complain. Or is it actually that Xiao Jing is not very good at imparting what he knows to others, so that he has lost his tongue for a long time but still can't let Xiao Si learn?

　　Leive, a teacher, came to give a fair judgment. He personally tends to be Xiao Jing's lack of "teaching ability" is the main reason. Although Levi himself is a liberal arts teacher, he must admit that from the analysis of a large number of samples observed in his long-term teacher career, at least in the high school stage of this study, as long as the outstanding children of science generally don’t resist, In the liberal arts courses, it is often possible to achieve very good results with hard work.

　　Since Kosi even has a good grasp of science, so normally speaking, at least the knowledge of liberal arts at the middle school level, which is still at the level of proficient memory, shouldn’t be too difficult to learn, right? It’s not the kind of complicated thing that people don’t know how many bends to turn after going to university or even research institute.” Metaphysics~www.readwn.com~ Levi estimated that the reason why Xiaosi was complained by Xiaojing might be small Jing's responsibility as a sister is still greater.

　　 Of course, Xiaosi’s brain is slower than the average students of the second middle school. This is probably certain. After all, everyone sits in the same classroom every day and listens to the same teacher to teach the same class. The final test scores are different, but it is necessary to insist that there is no difference in ability between each other. I am afraid that even the optimistic students themselves know that the teacher is comforting themselves.

　　 On the other hand, Xiaojing is probably the type that he can learn well but can't communicate well what he knows to others. Levi felt that with Xiaojing's personality analysis, there was nothing surprising about this kind of thing. After all, Xiaojing was originally a typical Aojiao girl, and the existence of Aojiao was often not because she was not good at expressing, or dared to express, and was unable to express herself, which led them to always make it simple and directly cope with the situation. Is it complicated or even the other way around?

　　 "So why do you have to turn the iron bucket around? It feels so tired to turn around with such a big iron bucket..."

"Yes, yes! At the beginning, I heard that Miyuki said that it was necessary to turn the iron bucket all the way to make ice cream, and I came up with a way to roll the iron bucket directly off the hillside. There is a lot of milk and cream. Without the help of a machine or the like, the girls alone will keep turning around until they make ice cream. Maybe everyone is tired and can’t eat it!”

　　 For a while, Quan Quan, who didn't open his mouth, finally found a chance to speak. Although the words she rushed to say had a great suspicion of excuse for herself, it did have her own reason.
