In the formation space, four people and one dog condensed and formed, and the light gate had long disappeared, and the stone platform had risen.

Zhu Lang pressed the stone platform with his hand, and the task light curtain unfolded, displaying a line of text: 'Submit an observation report. ’

Yeon-yeon hurriedly stepped forward and spread out the notebook on the stone platform. The light curtain sweeps over, and an 'observation report' is projected on the mission light curtain.

Theme: "I am curious" about nature.

Activity: Observe the 'stone' blooming, "I'll ask a question".

Panelists: Zhu Lang, Yanyan, Kiki, Binbin.

Observation Notes:

1. The shape of the raw stone flower is peculiar, like a colored stone, like a pebble and has life. The raw stone flower plant has gray, green, brown and other colors, and the fleshy leaves are thick, and the two pairs of leaves are connected to form an inverted cone, and there is a crack in the middle.

2. Raw stone flowers produce flowers at the top of the plant, with yellow, white, pink, red, purple and other colors, and the flower diameter is 3 cm. When flowering, the flowers cover almost the entire plant, which opens in the afternoon and closes in the evening. The flowers are brightly colored and very beautiful, and have a high ornamental value. [Attached: 1-minute fast-shot video.] 】

"Babe, play the video."

The change of Shishenghua for most of the day is shortened to 1 minute, which clearly reproduces the complete process of Shishenghua from flowering to closing, vivid and intuitive, which is irreplaceable by language description, and the effect is also leveraged.

The three friends were confused by the 'video', and Bin Bin questioned loudly: "Captain, where did the video come from?" ”

"When you went to visit, I asked Bei Bei to record it."

"Can you still ask Beibei to help? You're cheating! ”

"Bei Bei agrees, otherwise you can see the process of the stone flower blooming so intuitively? I paid the price to get it, and you still don't accept it if you watch it for free, it's really unconscionable! ”

"At what cost?"

"Confidential!"

Binbin was speechless, his lips opened and closed and he couldn't hold back half a word, and his face was flushed.

Zhu Lang now knows how cool it is to spit out the word 'confidential', no wonder Bei Bei used 'insufficient authority' to deal with him at a critical moment, isn't he also as depressed as Binbin?!

"Things often change over a long period of time, and using a fast camera to observe the change time will greatly 'shorten' the change time, which is vivid and intuitive, and is a common means of observing the growth of plants. Congratulations to the prodigal son, the video works very well and rewards 100 points. ”

"Haha, there are points again, the more the merrier~"

At this time, the mission light curtain gives the trial event reward: submit an observation report and reward 200 team points.

Zhu Lang looked around and said loudly, "Let's start asking questions." ”

Yeon-yeon raised her hand and asked, "Captain, is there a conditional limit to the questions raised?" For example, can only ask questions related to the active task? ”

Zhu Lang scratched the back of his head, couldn't answer, tilted his head and looked at Beibei: "You explain to everyone." ”

Bei Bei said casually: "The question is open-ended, you can know the answer or not, as long as it is a valuable question." ”

Kiki was the first to jump out: "I'll come first: what is curiosity?" What does it have to do with learning science? What is the relationship between things in nature and things in everyday life? Why is there thunder and lightning in the sky? Where does the rain come from? How is the wind formed? ”

"I also have a lot of questions: Do caterpillars have eyes? Why do we smell flowers? Why are there no trees in the grassland? How do mushrooms grow? Yanyan said glutinously.

The corners of Binbin's mouth twitched, and he pulled Mu Mu's skin: "My question is about animals: why did the kitten fall from a height and be unharmed?" Why can geckos crawl on smooth walls? Why do chameleons change color? Why can we hear bees but not butterflies? ”

Zhu Lang glanced at the expression of the 'sour wood man' and couldn't help laughing.

……

"Captain, it's your turn!" Kiki poked Zhu Lang's arm.

Zhu Lang was about to speak, when a line of text appeared on the light curtain: "The captain explains what 'curiosity' is." ”

"Don't let me ask questions?" Curiosity'? Lao Tzu had to organize the language. He was silent for a moment and then spoke: "Curiosity is a strong desire to explore new things, and it is driven by curiosity to ask questions to my parents when I was a child, and to ask questions to my teachers after school. The French writer François once said: Curiosity makes scientists and poets. Scientists have had a strong curiosity since childhood, so Luban observed blades of grass and invented saws; The Wright brothers observed flying birds and invented airplanes; Edison had a strong curiosity from an early age and became an inventor when he grew up; Morgan observed the genetic variation in Drosophila and discovered the XY chromosome in the cell. ”

"Congratulations to the prodigal son, your explanation of curiosity is accurate, and the examples you give are reasonable, and you will be rewarded with 100 points."

The two little girls were shocked by Zhu Lang's words again, and there were signs of little stars emerging in the two pairs of big eyes, and Binbin immediately shouted: "You haven't said your problem yet!" ”

"Eh~ I've been thinking about several questions for a long time: What are scientists curious about? What questions have been raised? Why do birds fly in the sky? How many legs does a dragonfly have? When can I see a rainbow? ”

Zhu Lang saw that everyone was thinking, so he asked Beibei, "Beibei, do we need to answer the question we asked?" ”

"You don't have to answer now, you just know how to ask valuable questions."

"Then let's start answering today's question, Babe, what's the question this time?"

The light curtain flickered, and a few lines of text emerged.

1. Name the scientist in question.

(1) Who was curious about the apple landing, so he discovered gravity?

(2) Who was curious about the steam coming out of the kettle and improved the steam engine?

(3) Who has been withdrawn since childhood, likes to play with the compass, has a strong curiosity about it, and founded the theory of relativity?

(4) Who was curious about the chandelier shaking and invented the clock?

(5) Who is curious about hens hatching chicks and tries to hatch eggs for a day?

2. Answer the following questions:

(1) Why do birds fly in the sky?

(2) How many legs does a dragonfly have?

(3) When can I see a rainbow?

"I know, I know, the apple falls, gravity — Newton."

"Well, I also know that chandelier swings to invent the clock - Galileo."

"I know two: Watt's modified steam engine, Edison's hatching eggs."

"I know the rest: Albert Einstein created the theory of relativity."

So, Zhu Lang said to Beibei: "Beibei, in the order of the title, the names of scientists are: Newton, Watt, Einstein, Galileo, Edison. ”

"Congratulations, 50 Team Points Reward. Please keep up the good work. ”

"This time I got team points, so the points I got earlier are my personal points." Zhu Lang secretly thought, and then beckoned: "Partners, let's discuss the following three questions before answering, and strive to be accurate and complete." ”

"I went back yesterday and read about insects, and I'll answer." Yeon-yeon didn't answer yesterday, and she went back to tutor on the relevant knowledge. Then, word by word, she said: "Dragonflies are also insects, 3 pairs, 6 legs. ”

"Birds fly only when they have wings." Kiki added.

"Ostriches also have wings and can't fly, which means they have to weigh lightly." Binbin is not far behind.

After all, Zhu Lang is about to graduate from junior high school, and his general science knowledge is more comprehensive than that of his teammates, and he also joined the discussion: "Some insects and birds are good at flying, and having wings and light weight are the main reasons, but there are some reasons that cannot be ignored: First, they need air. If there is no air, the bird does not have the motivation to rise. Without air, birds cannot fly. Secondly, many of the structural features of birds themselves are also suitable for flight. ”

"Well, yes, the bird's bones are hollow and lightweight." Yeon-yeon softly agreed.

"The bird's body is streamlined and has feathers on the surface of the body, which reduces air resistance." Kiki also actively chimed in.

"Birds have particularly well-developed pectoral muscles, which can powerfully drive the wings to flap and provide strong power." Yeon-yeon added again.

Zhu Lang read the introduction of the Wright brothers in the extracurricular books, and brought out the knowledge in it: "Human beings once dreamed of realizing the flight of human beings, and the ancients once tied wings to their bodies and jumped from a high altitude, but they did not succeed, why is this?" This is because the person weighs too much and must have large enough wings if they want to fly. But to drive such large wings, humans need to have more developed muscles, which humans cannot do. ”

Zhu Lang and the two beautiful girls discussed.

"Airplanes were developed by studying the flight of birds."

"The fuselage of the aircraft is made of alloy material, which is light and strong, the engine provides the power, and the propeller creates lift, which allows the huge body of the aircraft to rise into the air."

"It's a helicopter with a propeller. Many planes don't have propellers now, how do they fly? ”
