Ding Xuecheng, as the group leader, naturally arranged tasks for others: "Partners, the second part of this activity has begun, let's first familiarize ourselves with other people's observation notes, and then let Bei Bei put together the notes of the four of us." If there is a gap, add it; If you feel that something is wrong, you can bring it up and discuss it. ”

After a while, everyone finished reading. Ding Xuecheng called Beibei: "Beibei, sort out the four notes." ”

The light curtain flashed, and the notes that had just been divided into four small pieces merged together, removing duplicate content and merging into a single observation note.

Theme of the event: Into Nature

Task: [Observe] What's in nature? What are some interesting natural phenomena in nature?

Panelists: Bobo, Yeonyan, Kiki, Binbin.

Observation Notes:

1. There are sun, moon and stars, earth, mountains, rivers and lakes, flowers and trees, birds, beasts, insects and fish. The sky, land, sea, and underground are home to a wide variety of animals, plants, and microorganisms.

2. There are many interesting natural phenomena in nature, such as wind, rain, thunder and lightning, the change of seasons, typhoons, earthquakes, volcanoes, rainbows, the morphological structure of plants, the strange abilities of animals, etc.

"Beibei, why is it so little?" The four of them asked in unison.

A passage appeared on the light curtain, apparently Bei Bei showed it to everyone.

"This is an abstract generalization, the first observation activity, you observe so much, everything is a cursory look, that is not observation, that is called browsing. Observation should have a clear purpose, be targeted, and study in detail with questions, rather than simply looking at a botanical garden or a zoo. The purpose of this activity is to guide you on how to observe, learn how to make observation notes, and prepare for future activities. Observation records should be realistic, not imaginary and exaggerated, and if you can't write, use pictures or pinyin instead. The outstanding performance of this event was Bobo, who took the question to see if there was mud under the sand and gravel at the bottom of the river. ”

Ding Xuecheng was a little secretly proud, both benefited and praised; The three friends looked at each other, and felt harsh at the sentence "Observation and recording should be realistic, not imaginary and exaggerated", and some of the things they recorded were imaginary, and they couldn't help but feel hot at the root of their ears; At the same time, I don't quite understand how Bei Bei said that Bobo "observed whether the bottom of the sand and gravel at the bottom of the river is mud" did it, Bei Bei didn't explain, and they didn't want to ask in detail, they were all repeating the meaning of the previous paragraph.

After being silent for a long time, the four of them seemed to understand the meaning of the words on the light curtain: this activity is to let everyone watch it casually, and then remind you - observation is not like this!

The thick lips of the polite flesh pursed out: "This is the teasing of Hongguoguo!" Why don't we start by observing a thing, for example, ants? It must be Bobo who didn't figure out the mission of this event, and he teased us! ”

"You, you're talking nonsense...... That's what I was tasked with! Ding Xuecheng almost went crazy, "This fat face is so hateful, everything is aimed at me!" ”

"Bobo is not mistaken, you see, this passage is telling us that there are many, many things in nature, and they are wonderful, and we need to keep learning." Qiqi was a little disgusted by polite words, and opened her mouth to support Ding Xuecheng.

"Well, I thought the same way, at first I felt that there were too many things to observe, there was no clue, everything seemed to be very complicated, for example, observing an earthworm, we only know what it looks like and what it lives in the soil, whether it has eyes, what it eats, how it digests food, whether it sleeps or not, whether it will die if it is broken, etc., we don't understand. It takes a lot of time just to observe this, so how can we observe everything in nature at once? Yeon-yeon tilted her head and said so much in one breath, she was a little tired and panting.

Seeing that everyone didn't support him, Binbin buried his head and sulked.

Ding Xuecheng knew that now was the critical moment to complete the task, so he didn't care about the polite attitude, so he immediately made a summary.

"Bei Bei arranged this activity to let us understand the richness and wonder of nature, so as to have a strong interest, study hard, to find, to discover, to explain, to explore the mysteries, to apply the knowledge of nature to the reality of life, to make our lives better!"

"Congratulations Bobo, the fundamental purpose of science is to serve the practice of social life, and is the driving force for the development of human civilization and society, and 100 points will be awarded."

Ding Xuecheng hurriedly checked his task attributes, and sure enough, the points had increased by 100 points, and now it was 32602, and he shouted happily: "Okay, partners, through discussion, we understand that we should carefully study the problem when observing in the future, and the future task may be a single problem, and we will not be as overwhelmed as we are today." Now, we're ready to start the third part of the activity – answering questions. Bebe, what's the problem this time? ”

Four questions are shown on the light curtain in a row:

1. How many pairs of fins do freshwater fish have? Where does it grow?

2. What kind of creatures do ants belong to? How many pairs of feet are there?

3. What is the difference between the front and rear legs of a hare? Why is the tail short?

4. Why can't I see the stars during the day?

Seeing everyone contemplating and thinking, Ding Xuecheng's brain also spun, and he thought in his heart: "I want to rely on these questions to complete the task and get points, and all questions are only valid if I answer them, I must get the right to summarize." ”

After the partners thought about it, Ding Xuecheng spoke first: "First the corresponding observer will talk about the idea, then everyone will discuss and supplement, and finally I will summarize." The first problem is in the river, and I've observed, that the small fish have a pair of fins under the gills (thorax) and a pair of fins near the vent of the abdomen, so it's two pairs. Do you have anything to add? ”

"I've seen Dad kill fish, it seems like this."

"I've also seen the fish that my mother bought, saying that someone else caught it in the river, just like Bobo said!"

"Who doesn't know, the role of fins is to control the direction of fish when swimming in the water, I have already read it in popular science books!"

"Congratulations Bobo, answer correctly and reward 10 points." At the same time, Ding Xuecheng's answer is revealed under the first question on the light curtain - freshwater fish have two pairs of fins, one on the chest and one on the abdomen.

Yanyan stood up and said softly: "The second question is mine, I have carefully looked at the ants, there are a bunch of antennae on the head, there are 3 pairs under the body, 6 feet, one pair on the chest, two pairs on the abdomen. Do you have anything to add? ”

"You haven't said what kind of genre it belongs to!"

"Bugs."

"No, reptiles."

"You don't read much, it's insects, I've read popular science books."

Ding Xuecheng felt that although this fat face was not pleasing, his book knowledge was still very good, so he hurriedly summarized: "Okay, I agree with Binbin's point of view, ants belong to insects and have 3 pairs of legs. ”

"Congratulations Bobo, answer correctly and reward 10 points." At the same time, Ding Xuecheng's answer appeared under the second question on the light curtain.

Kiki immediately jumped out and said hurriedly: "The third problem is mine, I can see clearly in the woods, the hare has short front legs and long hind legs, and like a frog, it jumps and walks. After speaking, he also learned to walk like a rabbit and jumped up.

Yeon-yeon: "Why is the rabbit's tail so short?" ”

Kiki said as a matter of course: "It's born like that, it's all short!" ”

"Did you get bitten off?" Yeon-yeon was a little unsure.

"No, I've read popular science books,...... But it doesn't seem to be said in the book, anyway, I don't think it's right. Bobo, you say! ”

Ding Xuecheng knew the phrase "the tail of the rabbit can't grow", but why "can't grow", he really didn't think about it. He remembered Kiki's bouncing appearance just now, and a flash of inspiration flashed in his mind: "The rabbit's tail is too long, and it has a big tail like a squirrel, isn't it inconvenient to jump?" ”

"Cut~, aren't the squirrels also jumping and walking?"

"Did the long-tailed rabbits all be eaten?"

"No, I've never seen a rabbit with a long tail! Or rather, rabbits that don't have long tails. ”

Ding Xuecheng had to guess: "Unless the rabbit controls its tail not to grow in order to escape from natural enemies!" ”

"Haha, laugh at me, can you control your body from growing?" Binbin pointed at Ding Xuecheng and laughed so much that tears flowed out.

"Bebe, our answer is: rabbits have short front legs and long hind legs, jump forward, and don't let their tails grow long in order to escape."

"Congratulations Bobo, answer correctly, reward 50 points, very good, science is inseparable from conjecture, and bold conjectures that conform to reality are necessary."

As soon as Ding Xuecheng's words fell, the answer appeared under the third question on the light curtain.

"Yay~ Answer correctly!"

"Huh?"

"Oh~!"

"How is that possible? Can I politely deny it? Cut, you'll only guess, the blind cat meets a dead mouse! ”

"......, why does this baby have such a character? If you don't change it in the future, Lao Tzu can't help it......" Ding Xuecheng wanted to cry without tears, and shouted wildly in his heart.

He turned his head to stare at the fat face: "The last one is yours, how is it written in your popular science book?" ”

The three of them looked at Bin Bin in unison, his face turned red, and he stammered: "No, I didn't see this problem~ I think it's because the sun didn't shine on the stars, so I can't see it." ”

The two little girls didn't know the answer, so they looked at Ding Xuecheng, meaning to let him answer.

Ding Xuecheng had no way out, his brain turned sharply, "I can't see, I can see it, I should see it but I can't see it......"

"Cut, I thought you could get it right again, it's not the same, what's the use of tongue twisters? Maybe my answer is right! ”

"By the way, do you think the actors in the stage lights can see the audience?"

"The lights don't shine on the audience, of course they can't see it."

"yes, it's still my answer!"

"People who aren't under the lights can see the audience, right? The audience can see each other~"

"This ......"

"Beibei, my answer is: under the sun, the ambient light is too strong, far more than the light emitted by the stars, and the light of the stars is covered by the strong light, so it is invisible."

"Congratulations to Bobo, the answer is basically correct, and 30 points will be awarded. The optic nerve of a person is stimulated by strong light and does not respond to low-light stimuli, so it cannot be seen. ”

Bei Bei showed the full answer, Bin Chubby blushed, and stopped talking.

At this time, a line of big words floated out on the light curtain: This event is over, goodbye!

Then the three of them turned into three light clusters and disappeared, Ding Xuecheng breathed a sigh of relief, and finally asked the question that had been pressed in his heart for a long time: "Beibei, how did they go?" How can it be turned into a ball of light and disappear? What is this place? How do I get back? Can I use my points? ”

"Don't rush, take your time, tell you everything you can tell!"
