"The classmates are optimistic, what are I taken in my hand? Yes, it is a cartoon album. Everyone can see that the pattern inside is black and white or color? Yes, black and white. However, I want to remind the students to pay attention to It is not an ordinary book. It is a book that will change magic! "On the morning of September 20th, in the multi -functional classroom of Jinhe Hope Primary School in Jinhe Town, Xichuan County, a vivid popular science class Standing.

Two "special teachers" standing on the podium, one named Pei Jingru, and the other named Kang Panpan, both from the Zhengzhou Science and Technology Museum. The performances that they brought to children today are called "Charming Science Class". It is a veritable "scientific experiment show" that is both thrilling, fun, and interesting. Welcome to one of the 30 special science popularization activities of the 20th Popular Science Dharma.

The spacious multifunctional classroom was full of nearly 200 children, and they stared at the movements of the two teachers on the stage. I saw Pei Jingru shook the magic book in his hand and trembled in the air, and when he opened it, the patterns in the book all turned into colors. "Wow, it's amazing, this is really a magical book!" "Well, it's strange, how did it transform? I didn't see it clearly!" His eyes and face were surprised, full of doubts about the scene in front of me.

"The classmates are quiet, and the performance is not over yet. Please look at the magic book in Teacher Pei's hands. What new tricks can you change!" Looking at the eyes of the children looking forward to, Kang Panpan reminded them to continue to pay attention to Pei Jingru The magic book in your hand. Then, Pei Jingru repeated the movement just now. When the book unfolds again, the patterns in the inside disappeared, and the whole became a stack of thick white paper. "It's interesting, I also want a magic book like this!" A child whispered to his classmates.

Pei Jingru and Kang Panpan's wonderful magic opening performance suddenly suffered the appetite of the classmates. The content of the "Charming Science Class" in the next enable students to open the eyes.

"Classmates, I have watched the TV series" Journey to the West ". What is the hottest place in it? Do you know?" "Flame Mountain!" The children in the audience said in unison. "Very right, next, Mr. Kang will perform the" Flame Palm "to the students, please pay attention to observation." Pei Jingru's voice just fell, and I saw Kang Panpan stretched out his arms and put his palms in the water bowl on the table. Wet, then sprayed on the burning, then lit the fire, and a group of flames rose on the palm of her palm instantly. The children under the audience exclaimed, and some suddenly stood up from the seat. "Is such a big fire burned out?" "The flame burned directly in the palm, it must be painful!" When he discussed and touched his head, the flame in Kang Panpan's hand went out. She showed her palm to the children in the audience, easy to be free, everything was not damaged, and the children were even more strange to see these.

"Classmates, why didn't the flame burned to my hand? First, because my hand just dipped in a special water, it formed a protective film; the other was because the flame was burning, The temperature of the inner flame is low. My hand is exposed to the flames of the fire, so it will not be burned. Do you understand the truth? "" Understand! "The children answered loudly. "Then let me ask everyone again, can you do such an experiment at home?" "No." The teacher is led by the teacher to do it, and you must not do it at home, otherwise there will be danger of causing fire and burns! "

In the following "Magic Magic Water" experiment, Pei Jingru and Kang Panpan invited several students from the audience to complete them together. The children stepped onto the stage and poured the colorless and transparent water into different glass measuring cylinders. At this time, the miracle happened, and the water in the three measuring tube quickly became yellow, red, and blue. Explained the scientific principles of "magic magic water" to the students, and the children in the audience were once again dumped by the charm of science. "Experiments are fun, science is really interesting!" Chen Mengyuan, a second -year student, watched the "Scientific Experimental Show" performance, could not hide his inner excitement and excitement.

Happy time is always short, unknowingly, this vivid popular science lesson is about to end. The children seemed to have not been addicted yet. They reluctantly left the classroom, but it can be seen that science has quietly entered their young hearts and will bring them joy and hope.

"Thank you for this popular science cable event, providing us with an opportunity to communicate with children, so that we can bring vivid and interesting scientific knowledge to more young people, thereby stimulating their scientific interests, enhancing their scientific science Consciousness, cultivate their innovative spirit, the state requires schools to strengthen scientific education, actively organize and support teachers and students to carry out a variety of popular science activities, we are also willing to contribute to the development of the popular science cause! " One member, Pei Jingru said his voice.
