Requesting a scientific observation diary for sixth grade students

"Autumn is here, autumn is here, the soybeans are full in autumn..." October in the golden autumn ushered in the peak harvest season. Look (with photos of picking edamame), at the planting base of Mudu No. 5 Primary School, a group of red scarves are working in groups of two and three, some plucking, some picking, and some carrying, picking the fruits of their labor. Fruit, everyone is very busy. There were bright smiles on the faces of the team members. No, I don’t know who took the lead in singing the song, and laughter suddenly floated over the base...

In the spring of 2002, the school’s Young Pioneers were in the original On the basis of in-depth implementation of various activities, a small labor planting base was opened according to local conditions. The purpose is to provide opportunities for team members to engage in planting activities within their capabilities, gain direct perception and development of skills, fun, etc., and at the same time allow them to both hone their skills and Train your will, increase your knowledge, and subtly achieve the effect of educating people. Unexpectedly, after more than two years of perseverance, planting actually became popular, which brought some unexpected harvests and became a special activity of the school's Young Pioneers.

Meticulous division and vigorous reclamation

There is half an acre of vacant land in the northeast corner of the school, which has been idle for a long time. Spring is here, and compared with the blooming flowers and lush trees elsewhere on campus, the feeling here is too vivid. The Young Pioneers Brigade felt it was a pity that it was deserted and decided to open it up for students to try planting. Firstly, it would further change the appearance of the campus, and secondly, it would allow the team members to engage in practical activities. The whole school counselors and squadron leaders discussed it at a meeting and got an immediate response.

Suddenly, the wasteland became lively, with measuring tapes and lines drawn with lime... Before long, half an acre of wasteland was neatly divided into 12 squadrons, and each class from grades three to six had 12 squadrons. Contract a piece. The next day, members of each squadron who enthusiastically signed up to join the planting team brought sickles, shovels, hoes, buckets from home... to reclaim the wasteland.

The sixth-grade students are so strong that they turned over a lot of soil with just one hoe. Are there any small stones? It doesn't matter, I was thrown far away in an instant; the fifth grade students are the most serious, they manage scientifically, work in line, divide work and cooperate, they are so fast, a piece of land will be completed soon; it is really not easy for a few chubby students in the fourth grade, their faces are full of pain They were all red, their feet were firmly planted on the ground, and they were hoeing again and again. They were sweating and didn't even bother to wipe it off. Although the third graders were young, they were not vague at all in their work. They first sprinkled water on the dry mud, and then As soon as the hoeing went down, all the mudbags turned over obediently. While working, they reminded other team members to be more aggressive and not to act recklessly. Hey, do you think it's annoying?

Songs slowly sounded on the base: "Love to work since childhood", "Labor is the most glorious", "I am the little master of the school"... After plowing the land, picking up small stones, and sprinkling water, the wasteland was instantly transformed. New look: ridges and ridges appear before our eyes. Then, the team members began to fertilize the wasteland. They worked enthusiastically one by one, and the singing became louder and louder, floating farther and farther away.

Sowing intensively and cultivating with confidence

The soil that has been fertilized and baptized by rain is black and oily, and looks beautiful. The team members are clamoring to sow seeds,

There is no other way, just satisfy them.

Each squadron is fully responsible for buying seeds, selecting seeds, and sowing seeds, and the responsibility lies with everyone. Since they had no experience in planting at the beginning, the team members felt everything was new and made a lot of jokes: when planting Chinese cabbage, some took the lettuce as Chinese cabbage to sow; when arranging garlic, some students inserted a whole head of garlic into it. In the soil; some of the seeds I bought are already out of season...

Looks like I have to ask for advice. In the following period, the team members asked teachers, parents, and farmers for advice, and the harvest was quite big: for example, after the Qingming Festival, they can start planting edamame, eggplant, peppers, tomatoes, pumpkins, etc.; in summer, due to the high temperature, they can plant small Cabbage; in autumn, after the white dew, it is suitable to plant spinach, radish, garlic, peas, coriander, etc.

Since I have mastered the golden idea of ??combining planting with the season, everything that follows will be much smoother. Team members continue to experience the joy of labor and planting in person.

As soon as they are free, the team members go to the labor base. Some practice turning the soil, some watering at the right time, some pulling weeds, fertilizing, and catching insects in time, and some bend down to see if the seeds they planted have germinated. Look at the seedlings to see if they have grown taller, and count how many more leaves they have sprouted. Should they be divided? Looking at the well-growing labor base, the team members are all confident, not to mention how happy they are. !

Tasting the harvest with joy and smiles

Seeing that the eggplants have bloomed (with photo of eggplant blossoms), I counted a small watermelon lying in the leaves (with photo of watermelon). The body of the gourd is slowly getting longer (with a photo of the slender gourd), and the waistline of the pumpkin is getting thicker and thicker (with a photo of the big pumpkin)... watching the seeds planted by myself taking root, sprouting, blooming, and bearing fruit, the harvest day is getting closer. , the happiness of the team members was beyond words.

After patiently nurturing and anxiously anticipating, we finally waited for the day of harvest. The whole class is dispatched in a swarm to see which class has the best labor base! look! The soybeans in this class are plump, and the green vegetables in that class are shining; the radishes here are slender and watery, and the cabbages there are attractive in color; amidst the cheers, small round watermelons appear in front of everyone; there are surprises In the middle, several big pumpkins were carried out... Those who harvested and those who watched had bright smiles on their faces. The baskets were lined up one by one. The junior headquarters weighed each class's harvest one by one and carefully recorded it. Amidst bursts of cheers, these baskets were sent to the school cafeteria.

At noon the next day, the chief counselor came to the cafeteria and announced through the loudspeaker: "Students, let me tell you good news. Our planting base has achieved a bumper harvest this season. The vegetables you eat now They are all the fruits of our own labor. These vegetables are very fresh, and they are very meaningful to us. They are rarely tasted." After hearing this inspiring speech, the students cheered again and tasted them with seriousness. From time to time, the school reporter walked among the crowd: "Excuse me, what do you think of the taste?" "It tastes great!" "It's so fresh"...

Looking around, the cafeteria is full of smiling faces; Listen carefully, there are "tsk" sounds all around...

Establishing examples and commending and carrying out activities to temper

Strike while the iron is hot has the best effect. At the flag-raising ceremony, the Young Pioneers reported on the planting situation, commended the team members who worked hard and sweated under the scorching sun in the previous stage, and called on the entire school to learn from them and carry out a series of "happy labor" activities throughout the school. The school specially issued a "Letter to Parents" explaining the event and asking parents to actively cooperate.

Soon after, the counselors received feedback sheets from parents: Some said that since their children joined the planting group, they have got rid of the habit of wasting money and are much more sensible than before; some said that their children have become more sensible than before; Really understand the meaning of the Tang poem "It's noon on the day of hoeing, and the sweat drops and fall into the soil"; some said that they understood the difficulty of farmers' life; some said that the little emperors and princesses in the past always opened their mouths with food and clothes. In terms of skills, parents take care of everything, but now they can learn to do self-service tasks such as washing hair, washing clothes, making beds and rooms, and can even help parents with housework within their capabilities, such as lunch Setting up tables and watering flowers in the house; some said that their children even planted trees and planted vegetables in front and behind the house with their parents. Some children even took the initiative to learn to cook and cook at home...

Looking at the school again: the team members exchanged their labor experience with each other and felt the joy of labor... The more details such as picking up garbage and being helpful, conveyed a gratifying message: the team members generally got Through exercise, they generally felt the happiness that labor brought to them, and generally developed good labor habits.

In-depth education activities and improved overall quality

Planting activities brought endless joy and sweetness to the team members. In the diaries and compositions of many students, they reveal their love for planting activities and their nostalgia for happy labor.

A classmate wrote in his diary: As soon as I ran into the house after school today, I happily said to my mother: "Mom, we had spinach soup at school today. It was so delicious!" My mother was serious. Said: "You like to drink spinach soup, then mom will make it for you tomorrow!" "No, that's not what I mean.

Mom, you don’t know that the spinach you eat today was grown at our labor base! "My mother smiled and said: "Yes, labor is the most delicious! ”

It’s true that labor can educate people! The school’s youth headquarters lost no time in providing work guidance, and each squadron also launched a series of interesting and informative evaluation activities from the planting activities. Such as the bean picking competition , fruit platter competition, "Labor is the Most Glorious" theme team activity, etc. The holiday labor team composed of sixth-grade students sold the picked vegetables and other vegetables at the small market to conduct social practice and carry out experience activities. I pooled the money I earned with my own pocket money to buy fruits and cakes, and went to visit the grandparents in the nursing home in Mudu Town. This was well received by parents and the society. A counselor from the squadron said sincerely: “Labor practice has improved. It improves the ideological and moral, cultural and scientific, physical and psychological qualities of the team members, and also improves their self-care and self-reliance abilities. The labor base is a good place for students to show their abilities! ”

What makes the teacher most happy is that the mantra “Labor is the most glorious” often hangs on the children’s lips. Their living ability and labor quality have been improved, and they all understand that they are family members. As a member of society, school, and society, we understand that we have rights, obligations, and responsibilities to care about things around us, and all of this is due to the development of planting activities.

What started out as an idea has now taken root and blossomed on the campus of Mudu No. 5 Primary School, bearing fruit. The school has also taken this opportunity to pay more and more attention to labor education and find ways to broaden the scope of labor education. Channels. The school continues to strengthen the construction of the campus labor base, and has purchased a series of basic tools for students to practice, trying to create conditions for the improvement of students' labor skills, and the characteristic activities of the school's Young Pioneers are gorgeous. Flowers. We believe that in the near future, the teachers and students of the Fifth Primary School will take good care of this Qiba, so that it will continue to be nourished and bloom more vividly and more attractively. This special activity of the Young Pioneers will also become the school's characteristic activity. A beautiful sight on the road to labor education! My mother once gave me this riddle: "Nanyang Zhuge Liang, sit firmly in the army tent. Arrange the Bagua array and catch the flying general alone. "This riddle tells us: Spiders only eat living things, don't they eat dead things? This aroused my interest, and I did an experiment.

I caught a spider from the corner I put a small spider into a box (with small holes around it and a glass cover for easy observation). Before the spider could weave its web, I picked up a dead bug and a dead fly and put them in. In front of the spider, the spider ignored it, and then bumped the box with my hand, and the spider crawled in other directions.

In order to fully understand whether the spider can eat dead flies, the next day, I came to the box again. I looked forward and saw that the dead insects and flies were still in their original places, but there was a web in the corner of the box, and the spider was lying quietly on the web. At this time, I thought: The dead flies and dead insects were not eaten yesterday. Isn't it because there is no net? So, I picked up the dead fly and gently placed it on the net, but the spider was still motionless. Then, I gently touched the edge of the net with a pen. Hey, the spider seemed to have After a while, the spider crawled toward the center of the web again and touched the dead fly on the web with the tip of the pen. My body, the web began to tremble, and the spider began to crawl towards this side. I took the pen tip back, and the spider stopped. Just like last time, after a while, the spider crawled towards the center of the web again. Oh, I finally understood! : It turns out that spiders rely on the trembling of their webs to produce feelings, and they hunt by weaving their webs.

In order to confirm that spiders rely on the trembling of their webs to produce feelings, I did it again. Experiment. Place the tip of the pen on a dead fly on the web. After shaking for a long time, the vibration of the web becomes stronger and stronger. The feeling of the spider seems to be getting stronger and stronger. The spider rushes over. When the spider touches the fly, I When I retracted the pen tip, I saw that the tail of the spider quickly sprayed out sticky silk to tie up the fly. Then I watched the spider's back move as if it was sucking the fly. After a while, there was only a complete empty shell left on the web. This experiment proves that spiders eat moving insects.

Our detective team went to libraries and bookstores to read a lot of books about spiders. The book "General Zoology" said: Spiders are. Carnivorous animals whose food is mostly insects or other arthropods.

But the mouth has no roof of the mouth, so it does not swallow solid food directly, but sucks it slowly. When insects and other animals touch the web, they will struggle hard on the web, causing the web silk to tremble and the spider will soon notice it. The spider will crawl towards the prey along the longitudinal silk, wrap the prey with the spider silk, and fix it on the web. First, it uses its chelicerae. The venom glands inside secrete venom and inject it into the body of the captured prey to kill it. The digestive enzymes secreted by the midgut are then infused into the tissue of the prey torn by the chelicerae, quickly decomposing it into juice, and then sucked into the digestive tract. , and finally the remaining body shell was eaten and completely abandoned on the spider web. This fully proves that flying insects make the spider web tremble, and the trembling of the web will produce feelings, and the spider will capture the prey when it feels. Therefore, it is confirmed that spiders only eat live animals, not dead insects.

Broadly speaking, any work that discusses scientific and technological content is called scientific writings, such as original works, briefings, comprehensive reports, progress reports, literature reviews, reviews, monographs, compilations, textbooks and popular science Readings, etc. But among them, only the original treatises and their briefs are original, major, first-rate, and involve intellectual property rights such as creations and inventions.

Others are of course important, but they are all processed, developed, and written for specific application purposes and objects. The following will only talk about some experiences in writing original papers, and also talk about some experiences in how to make academic reports. When discussing the writing of original papers, we are not prepared to talk about the various regulations and rules related to manuscript writing. What Dingde Culture Workshop talks about today is the problems and experiences that are easy to occur in writing, as well as the standard issues of writing ethics and writing content.

The requirements for essay writing are described below in order of the article structure.

(1) Title

Scientific papers all have titles and cannot be “untitled”. The title is generally about 20 words. The size of the topic should be consistent with the content, try not to include subtitles, and do not use the first report, the second report, etc. The questions should be written in a straightforward tone without using exclamation points or question marks. Scientific paper titles should not be written in the language of advertisements or news reports.

(2) Signature

Scientific papers should be signed with the real name and the real employer. It mainly reflects responsibility, achievement attribution and facilitates follow-up research by future generations. In the strict sense, the author refers to the person responsible for the entire process of topic selection, argumentation, literature review, program design, establishment of methods, experimental operations, data collection, summary, writing, etc., and should be the person who can answer the relevant questions of the article. Nowadays, it is common to list all the people who have participated in the work, and then they should be arranged in order of their contribution. Signature must be signed with the consent of the individual. The academic supervisor can either be listed as the author or give general acknowledgments depending on the actual situation. Executive leaders generally do not sign.

(3) Introduction

It is a fascinating statement, it is very important and must be written well. A good introduction often allows readers to understand the development of your work and your position in this research direction. It is necessary to write down the basis, foundation, background, and research purpose of the topic. It is necessary to review the necessary documents, describe the development of the problem, and the text should be concise.

(4) Materials and methods

Write down experimental objects, equipment, animals and reagents and their specifications according to regulations, write down experimental methods, indicators, judgment standards, etc., and write down Experimental design, grouping, statistical processing methods, etc. You have been reminded of the above details.

(5) Experimental results

Should be highly summarized, carefully analyzed, and logically presented. We should discard the rough and select the essential, discard the false and retain the true, but we should not make subjective choices because it does not meet our own intentions, let alone cheat. Only the data obtained when the technology is unskilled or the instrument is unstable, the data obtained when the technology fails or the operation error occurs, and the data obtained when the experimental conditions are not met can be discarded. Moreover, the reasons must be noted in the original records when problems are discovered, and they cannot be arbitrarily eliminated due to irregularities in the summary and processing. When discarding this type of data, experimental data under the same conditions and at the same period should be discarded together, and you should not discard only those that are not to your liking.

(6) Discussion

It is a more important part of the paper and a more difficult part to write. We should look at the overall situation, grasp the main controversial issues, and discuss them from perceptual understanding to rational understanding. Analyze and reason about the experimental results, rather than repeating the experimental results. You should focus on discussing the results and viewpoints in relevant domestic and foreign literature to express your own opinions, and in particular, you should not avoid opposing viewpoints. Hypotheses and development ideas for this topic can be put forward during the discussion, but the proportion should be appropriate and should not be written as "science fiction" or "imaginative".

(7) Conclusion or conclusion should write clear and reliable results and conclusive conclusions. The text should be concise and can be written point by point. Don’t use vague words like “summary.”

(8) References

This is a very important and problematic part of the paper. The purpose of listing references is to allow readers to understand the ins and outs of the research proposition and facilitate search. It is also to respect the work of predecessors and to have an accurate positioning of their own work. So there are both technical and scientific ethical issues here.

Almost throughout a paper, references need to be cited. For example, the introduction should cite the most important and directly related literature on the topic; the methods should cite the methods adopted or used for reference; the results should sometimes cite data that are compared with the literature; and in the discussion, the above should be cited. Various supporting or contradictory results and opinions related to this article.

(9) Acknowledgments

Directors, technical collaborators, those who provide special reagents or equipment, financial sponsors and those who have made important suggestions are all objects of acknowledgment. Acknowledgments should be sincere, real, and not vulgar. Don't give thanks in general, don't just thank the professor but not others. Before writing acknowledgments, you must obtain the consent of the person being thanked, and you cannot use the banner as a tiger skin.

(10) Abstract or synopsis

Briefly summarize the full text in about 200 words. Always put it at the beginning of the chapter. Be well written and attractive. It should make readers feel as if they have seen a miniature of the full text after reading the abstract, or want to continue reading the relevant parts of the full text after reading the abstract. In addition, several keywords should also be given. The keywords should be really key academic words and should not be made up of general words.
