Chapter 83: Opening the Door to Science (Part II)

The crowd made a false alarm and high-fived in celebration. Then he stepped out of the crowd and stretched out his left hand to press the "dry position", and the question that came to him was: "Please give an example of 'science is all around us'." ”

Since this is a team activity, one person answers incorrectly and the whole fails; No matter how confident Binbin was, he had to resort to collective intelligence. And Ding Xuecheng said that "I have learned this part of knowledge earlier", so Binbin looked at Ding Xuecheng.

Ding Xuecheng whispered a few words, everyone nodded, and Binbin said loudly: "Answer the question of the cadre position: the table tennis ball is deflated, and hot water can restore it; When the wind blows, the little windmill will turn; When the caterpillar grows up, it becomes a flower butterfly...... These seemingly ordinary things contain scientific truths, and science is all around us. That's it! ”

"Yay~ The dry position is lit up! Binbin, keep up the good work......" The two little girls cheered and jumped.

Binbin's right hand pressed to the "Gen position", and the question that came out made everyone feel embarrassed: "Can a paper pot also boil water?" Proven experimentally. ”

"Bebe, this is a matter of Binbin. If he wants to do an experiment, he has to take his hand away; If you take it away, it will fail, how do you get it? ”

"You do it instead of him~ You prepare for the experiment, Binbin says 'the experiment begins', and then you start the experiment, and after the experiment is completed, Binbin says 'the experiment is finished'. If the experiment is successful, the 'Gen Position' will be lit up. ”

Binbin said anxiously: "You guys hurry up, I will be very tired if I hold this position for too long!" ”

Yanyan said softly: "There is no experimental equipment!" ”

"Bobo, how did you get the magnifying glass last time?" Kiki asked, rolling her eyes.

"Rented with points." Ding Xuecheng hurriedly replied, and then raised his head and asked Beibei: "Beibei, you can also rent experimental equipment this time, right?" ”

"Yes, 10 points."

"Bring it quickly."

"Deduct 10 points, please go to the next laboratory table to complete the experiment."

The four of them turned their heads to look at both sides of the stone platform, and sure enough, a laboratory table slowly rose from the ground, and some experimental equipment was placed on the table.

The three of them hurriedly ran to the test table.

Kiki pointed to the experimental equipment and said first. "There are candles, matches, tripods, oily paper, transparent glue, scissors, colored pencils, and a glass of water."

Yanyan was embarrassed and asked, "Paper pot boiling water?" The paper pot will be burned, right? ”

Ding Xuecheng: "No, as long as there is water in the paper pot, the paper pot will not be ignited." The key is that the paper pot made of oilskin paper does not leak, let's get started. ”

Kiki: "Cut the oilskin paper into pieces and glue it with transparent glue." ”

Yeon-yeon: "If you want the paper pot to be water-tight, you have to minimize the seams of the paper pot, and then use transparent glue to stick it tightly on both sides inside and out. But how do you get to reduce the seams? ”

Bin Bin shouted from afar: "I have a way, I don't need to cut the oily paper, there is not a single seam, and finally fix it with transparent glue, absolutely no leakage!" ”

Ding Xuecheng and the two girls both looked at Bin Bin and asked in unison, "What's the way?" ”

"Make a paper pot out of a whole piece of oily paper and make a square box. First draw a square pot bottom in the middle, then fold it in half along the bottom of the pot, after erecting it, fix the overlapping part with transparent glue, and trim it with scissors on the left side, and the whole paper pot situation will be a whole, and there will be no leakage at all. Do you understand? ”

The two girls were confused when they listened, but Ding Xuecheng understood it at once, and hurriedly did what Binbin said. The diameter of the tripod is very small, and Ding Xuecheng made the bottom of the paper pot into a square slightly larger than the diameter of the tripod.

The three of them cooperated, and 5 minutes passed, and a paper pot made of a whole piece of oilskin paper appeared in front of the four people.

The two girls exclaimed: "It's really a whole~ If the oilskin paper is not broken, the water will not leak!" ”

Ding Xuecheng poured a small half cup of water into the paper pot, about 1cm deep, and then put the paper pot on the tripod and shouted to everyone: "Okay~ light the candle." Binbin, you're ready to start experimenting! ”

Binbin replied: "The 'paper pot boiling water' experiment begins!" ”

Yeon-yeon lights the candle, and Kiki secures the candle.

Ding Xuecheng moved the tripod above the candle flame, breathed a sigh of relief, and said: "The candle flame is small, and the water can't be put too much, otherwise it will take too long, and it will not be easy to boil the water." ”

Kiki was full of questions: "The candle flame burns the center of the bottom of the paper pot, it can't burn the side, but it will also burn the bottom of the paper pot, right?" ”

"Hmm~ I think so too!" Yeon-yeon agreed.

"When the water is boiled, it boils, about 100°C, and the temperature remains the same; This temperature is much lower than the ignition point of the paper, as long as there is water in the paper pot, the paper pot will not be lit. You can rest assured to see the results~......"

After another 4~5 minutes, Binbin complained bitterly, and the water in the paper pot also boiled in a thousand calls.

"Wow~ The water is really boiling!" Kiki screamed.

Yeon-yeon's eyes widened and said, "The paper pot can really boil water~"

Ding Xuecheng shouted excitedly to Binbin: "Binbin, the experiment is successful!" ”

Binbin also forgot about the sore arm, and hurriedly said, "The experiment is over!" ”

With Binbin's words, the "Gen Position" on the stone gate was lit up.

Binbin ran over and high-fived Ding Xuecheng to celebrate each other, and Qiqi took Yanyan's hand and danced happily.

Ding Xuecheng said to Yanyan: "It's our turn!" Do you come first or do I come first? ”

"I'll come first~ Tell me the answer in a moment, I don't want to cause everyone to fail because of me!"

After Yanyan finished speaking, she walked to the stone platform and stretched out her right hand and pressed it on the "Kan Position". The question that arises is: "What is this?" Then a picture of what looks like the surface of a stone ball, with a pitted surface that appears to be a meteorite.

Kiki pointed to the enlarged picture and said, "It's a strange stone!" ”

Yanyan just wanted to say "It seems to be an asteroid", but Ding Xuecheng stopped her and signaled her not to speak.

Binbin touched the back of his head and hesitated and said, "It seems to be the shot put used in physical education class." ”

Ding Xuecheng had read this part of the content in a science textbook, so he naturally knew what it was, and said to Yanyan: "Observation is a basic method of scientific research, but sometimes it is not enough to rely on the observation of sensory organs, and in scientific research, it is often necessary to use some scientific instruments. This is a picture of the surface of a grain of sand, but seen under an electron microscope. If you look at the picture below, the device that is much more complex than a microscope is the electron microscope. ”

Everyone looked closely again, was shocked, and exclaimed in unison: "Almost wrong! If it's wrong, it's over......"

Yanyan glanced at Ding Xuecheng gratefully and said, "The answer to the Kan position question: This is a photo of the surface of the sand grains. That's it! ”

The three friends looked at the stone gate nervously, and the stump on the gossip pattern of the stone gate was lit up, and everyone was jubilant, with a feeling of dying and surviving.

Yanyan raised her left hand and pressed it to the "Kun position", and the question that emerged was: "There are stories of 'clairvoyance' and 'Shunfeng Ear' in myths and legends, as well as the stories of 'Monkey King making trouble in the Dragon Palace, borrowing the sea god needle' and 'Chang'e running to the moon', please use modern technology to prove that science is progressing, and we can also achieve the things in myths and stories." ”

Yanyan understood the long question, turned her head to look at Ding Xuecheng, and Ding Xuecheng told her the answer again.

Yanyan said with confidence: "The answer to the question of Kun position: the telescope and satellite in modern life are 'clairvoyance', and the telephone is 'Shunfeng Ear'; you can also go down to the bottom of the sea to explore with diving equipment, and you can go to the moon with Shenzhou spacecraft to investigate." This knowledge shows that science is progressing and that we can achieve what is in mythology. ”

"Oh ~ yes ~ Kun bit is also lit up! We are one step away from opening the 'door to science'......"

"Bobo, come on!"

"I'm sure Bobo is fine! We're going to make it~"
