"If Lao Tzu hadn't seen this picture, he would definitely misunderstand it, saying that it was a strange stone or an asteroid, or even thinking that it was a shot put used in physical education class. But now~ hehe......"

Zhu Lang had read this part of the content in the science textbook, and naturally knew what it was, so he said loudly: "Observation is a basic method of scientific research, but sometimes it is not enough to rely on the observation of sensory organs. This is a picture of the surface of a grain of sand, but seen under an electron microscope. ”

Bei Bei looked at the hexagram below worriedly, and when he saw that the position was lit up, and the treasure chest appeared under the light blue light, it sang loudly: "I know, you must be able to do it, and you will definitely be able to answer correctly." Sure enough, you got it right, you're amazing! ”

Zhu Lang glanced at Bei Bei and said indifferently: "Your level of praise has dropped!" It's too bland. ”

"I will definitely work hard to learn Chinese knowledge ~ improve literary literacy!" Bei Bei hurriedly made a statement. Seeing Zhu Lang stepping on the next hexagram - 'leaving the position', the question emerged, so he hurriedly translated: "Experimental verification: Where does the white mist on the popsicle come from?" ”

Zhu Lang pursed his lips and muttered: "Pediatrics~ Of course, others say that it came out of the popsicle." But I already knew the answer, and the method of verification is also very simple! ”

He turned to Beibei and asked, "Do you want to experiment?" Where to do it? You need lab equipment! ”

Bei Bei pointed at his short limbs and shouted: "Oh~, behind, the stone platform in the center has risen again!" ”

Zhu Lang turned his head and found that the sunken stone platform had returned to its original state, with a plate on it, and inside the plate was a popsicle, surrounded by a trace of 'white mist', and there was a piece of plastic film on the side.

"This is for me to experiment, right? I got the answer and then said it? ”

"If you know the answer, you can't say it first, you have to draw conclusions through experiments. Go ahead and do it! ”

Zhu Lang came to the stone platform and picked up the popsicle, only to see that the "white mist" on the popsicle was misty, and it really looked like it came out of the popsicle. He wrapped the popsicle in plastic wrap, and after a few moments, the 'white mist' still appeared, indicating that it did not come from the popsicle.

Zhu Lang tilted his head and asked, "Do you need to explain the reason?" ”

Bei Bei pondered and said, "Explaining the reason, maybe the treasure chest obtained can open something better." ”

Zhu Lang was overjoyed, and hurriedly ran to the 'departure position' and replied loudly: "The white mist on the popsicle is not coming out of the popsicle. There is water vapor in the air, and when the water vapor encounters the low temperature of the popsicle, it will liquefy and condense into very small water droplets, and a large number of small water droplets gather together to form a 'white mist'. That's it! ”

As soon as Zhu Lang finished speaking, the 'departure' was lit up, a red light appeared under his feet, and the treasure chest reappeared.

Zhu Lang ran to the 'Gen position', and the question that came out made him difficult: "Can a paper pot also boil water?" Proven experimentally. ”

"Beibei, I'm going to have to do an experiment again, troublesome!"

"The paper pot used for this experiment takes a little time to boil the water. The experimental equipment on the stone platform is available. ”

Zhu Lang slapped his thigh and shouted, "Made, I really regret it!" After the experiment just now, I should have eaten that popsicle, maybe it would be beneficial! ”

Bei Bei was stunned and hesitated: "Can you eat it?" ”

As he ran towards the stone platform, he said, "I didn't say that I couldn't eat it!" It's wasted~ It's gone! ”

On the stone platform are candles, matches, tripods, oily paper, transparent glue, scissors, colored pens, and a glass of water.

Zhu Lang muttered to himself in embarrassment: "Made, the teacher didn't demonstrate it at the beginning, and the paper pot boiled water?" The paper pot will be burned, right? …… Oh, the junior high school physics teacher said that the boiling point of water is lower than the ignition point of paper, and as long as there is water in the paper pot, the paper pot will not be ignited. The key is to make a paper pot made of oily paper so that it does not leak. What to do? Cut the oilskin paper into pieces and glue them together with transparent glue? It's not good! If you want the paper pan to be watertight, you should minimize the seams of the paper pan, and then use transparent glue to stick it tightly on both sides inside and out. But how do you get to reduce the seams? Think of a way, no need to cut the oilskin paper, there is not a single seam, and finally fix it with transparent glue to ensure that there is no leakage......"

Zhu Lang lowered his head to find a way, Bei Bei was so anxious that he jumped up and down, but unfortunately it couldn't prompt, so he could only do it in a hurry.

Zhu Lang folded and gestured with the oily paper for a while, and suddenly realized: "Use the whole oilskin paper to make a paper pot 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, erect it, fix the overlapping part with transparent glue, and trim it with scissors on the left side, and the whole paper pot is a whole. In this way, the paper pot will not leak at all. ”

Then he hurriedly got busy according to his own ideas. The diameter of the tripod is very small, and Zhu Lang made the bottom of the paper pot into a square slightly larger than the diameter of the tripod. A few minutes passed, and a paper pot made of a whole sheet of oilskin paper appeared in front of him and Beibei.

Bei Bei was pleased: "It's really a whole~ If the oily paper is not broken, the water will not leak!" ”

Zhu Lang poured a small half cup of water into the paper pot, about 1~2cm deep, and then put the paper pot on the tripod, lit the candle, and fixed it. He moved the tripod over 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." ”

Then, he said loudly: "The 'paper pot boiling water' experiment begins!" ”

Bei Bei asked: "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?" ”

Zhu Lang looked at the smart dog and said secretly: "I don't know this common sense yet?" Isn't that part of the assessment? …… Made, I almost fell into the pit! This kind of assessment is full of pitfalls. ”

Thinking of this, he was alert and corrected his attitude, and hurriedly explained to Beibei: "The water boils to 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. ”

After another few minutes, the water in the paper pot began to bubble, and then boiled in his thousand calls.

"Wow~ The water is really boiling! A paper pot can really boil water~" Bei Bei shouted.

Zhu Lang hurriedly shouted: "The experiment of 'paper pot boiling water' is complete!" ”

With Zhu Lang's words, the "Gen Position" was successfully lit, emitting a blazing white light, and the treasure chest loomed.

"Yay~ Success!" Zhu Lang held his scissor hand high, circled the stone platform, and then ran to the last hexagram.

Zhu Lang stepped on the 'exchange', and the question emerged, and Beibei's translation sounded: "Curiosity is the starting point of science, try to ask 3 questions like a scientist." ”

Such a question is simply not too simple, Zhu Lang cleared his throat and said solemnly: "Scientists are people who love to think and ask questions. Great scientific discoveries often begin with questions, and curiosity is the starting point of science. There are many, many questions in the world of science, such as why do birds fly freely in the sky? Why do people feel lighter in water? Why does the sun always rise in the east? Why can geckos crawl freely on smooth glass windows? …… That's it! ”

As soon as his words fell, the 'exchange' was lit up, the runes flowed, and the green glow shone.

After working for so long, Zhu Lang sighed: "Beibei, it's not easy, there is still one last step left." ”

"Those who travel a hundred miles are half ninety, and when they get here, they must not relax, 'insist that the green mountains will not relax, and the roots will be in the broken rocks.'" Thousands of blows are still strong, and the wind blows from east to west, north and south. 'Keep up the good work!' ”

Zhu Lang was speechless, and thought: "Nima, this smart dog is progressing quite fast~ Biting the text and chewing the words, the poems and epigrams are slippery......"

As the last hexagram is lit, it is a pure white light. Then, the light of the entire array flickered, the runes flowed, and the brilliance gradually faded, and finally, the stone platform sank, the center of the Bagua pattern lit up, and the yin and yang fish rotated. The black eyes of the 'Yang Fish' flickered, while the white eyes of the 'Yin Fish' did not respond.

Zhu Lang waited for a while, but still didn't wait for the prompt of 'task completed', and then he realized that Bei Bei was smiling.

"Made, it's a joke!" Zhu Lang sneered and walked towards the black 'fish eye'.

As Zhu Lang's footsteps stepped on the black 'fisheye', another question emerged: "What is science?" ”

Zhu Lang suddenly realized and said secretly: "This mission is to open the door to 'science', of course, to answer questions related to science. There are two 'fisheyes' here, one is science and the other is 'metaphysics' that complements science. And to open the door to 'science', it is necessary to know 'what is science'. ”

Zhu Lang was no longer entangled, and replied loudly: "Science is to observe and discover problems, ask questions, and ask 'why'; science is to use your brain and hands to study problems, answer questions, and explore 'why'." To be inspired by nature and life, to imagine, to create inventions, so as to serve the practice of life, this is science! That's it! ”

As Zhu Lang's last words fell, the black "fish eyes" on the ground no longer flickered, but emitted dazzling colored light, and a familiar light gate slowly rose from the Bagua Array. This light gate is exactly the same as the light gate that enters the assessment space.

Zhu Lang looked at the light gate in a daze, thinking about whether this was a means of science and technology, or a means of formation in 'Fantasy', and Beibei's voice came from his ears: "Congratulations, the task is complete, this assessment has passed, and your intelligence has been recognized." However, we still need to guard against arrogance and rashness, and continue to work hard! ”

The light gate disappeared, and the stone platform did not rise again, Zhu Lang looked at the space for a while, and asked excitedly: "Beibei, now that the event is over, you can open the treasure chest, right?" ”

"Who~ Nine treasure chests have appeared, you go and open them one by one."

Bei Bei didn't say anything about 'character' this time, which made Zhu Lang's excitement break through a few layers of heaven, and he excitedly touched the treasure chest at his feet.
