Example Once, the teacher left us a special assignment-let's use waste materials to make a work with scientific and technological content.
after much thought, I decided to "build a boat". When I got home, I found waste foam plastic as the hull, old toothpicks instead of steel nails, windows painted in blue water, and small red flags made of Jinlong fish oil labels.
everything conforms to the principle of waste utilization. A catamaran passenger ship was finally made.
I put the boat into the pool with great interest, but to my disappointment, it floated on the water without moving. How can I make it run? I've been thinking hard for a long time.
suddenly my eyes lit up. One day not long ago, I used several soap boxes. When the boat was playing in the bathtub, I suddenly found that one soap box was driving, but the other soap boxes were floating there.
I was very curious. I picked it up and found a small piece of soap stuck under it. Thought: is this little piece of soap at work? Yes, why not give it a bold try? I cut a piece of soap with a small knife and stuck it to the bottom of the boat, but I didn't see the boat move.
eh? What's wrong? Oh, maybe it's stuck in the wrong place? I readjusted it several times and still didn't move. At this time, I was a little disheartened.
I thought, forget it. Just at the moment when I was about to give up, "I have to think about it for months. Ninety-nine times the conclusion was wrong, but the hundredth time I was right."
Einstein's famous saying echoed in my ears for a long time. Yes! How can you do things by halves? I pulled myself together and tried again and again. Finally, I dug a slot under the waterline at the stern and stuck a small piece of soap on it.
when the boat enters the water again, wow! I saw it sailing straight ahead slowly. Looking at the moving boat, I muttered, "Why can soap make the boat move?" Hearing this, dad patiently explained, "It's because the surface tension of soap is greater than that of water."
it suddenly dawned on me. Through this experiment, I finally understand a truth: only by boldly trying can I succeed. 2. Describe a small-scale composition
The topic is "Explaining a small-scale production", which limits the composition style to a description-oriented style. Therefore, students should first understand the concept of an exposition before writing, what is an exposition, how to write an exposition, and several commonly used methods of explanation. In addition, I would like to remind everyone that it is best for the article to reflect the scientific spirit and innovative consciousness.
The first topic requires a brief introduction of a small production, such as greeting cards, bookmarks, handicrafts, etc. First, you should choose which small production to introduce, and then introduce its structure, characteristics and significance of its existence to everyone. Attention when writing: 1. Be sure to pay attention to the order of instructions to avoid clutter; 2. Try to use metaphors, which can make the language vivid and vivid.
The second topic is to write about the making process of a small handicraft. Of course, the writing order must be written according to the making order. Students who like to make small crafts by hand may wish to write this topic. If you want to write this article well, you need to pay attention to: 1. Be clear about the production process of this handicraft; 2. Be detailed and appropriate, such as the key steps of manufacturing the handicraft.
Homework
Dance on campus
Author: Qi Shanshan
When you see the topic, you will think that I am narrating a dance. Oh, no, I am introducing a piece of arts and crafts that I created alone. The name of my arts and crafts work is Dance on Campus, which is a very beautiful art work with relief effect. In this painting, I adopted the creative method of cutting, pasting and describing, which is my original creation. Can you make this method? No? If you want to learn, then do it with me-the first paragraph introduces the work "Dance on Campus" and invites everyone to participate interactively. This opened the prelude to the article.
first, let's prepare the materials: a piece of cardboard for shirt packaging, some candy wrappers, a mooncake box, scissors, glue and the covers of some old magazines. The first step is to prepare the materials. This paragraph is abbreviated.
are you ready? Ok! It's time for the second step. Let's be two dancers. First, fold the two pieces of candy paper forward and backward respectively, and then twist it to tie the upper part in a knot and unfold the lower part. In this way, the bodies of two children in flowered skirts are ready. Then, cut out the heads of two little girls on the cover of the old magazine and put them on the newly-made children, huh! Just right. Then the body and head are combined and glued to the cardboard together. Ha ha! Look, how beautiful these two little girls dance! The second step is to make dancers by cutting and pasting. The technique of production is detailed and has strong maneuverability.
what is the third step? By the way, let's do the environment for dancers to dance. There are many contents in this step. We want to build buildings, sky, lawn, audience, sun and so on. Take out the magazine with buildings on the cover, cut out a building like a teaching building and stick it on the upper right of the cardboard, which is enough to show that this is a campus. Then paint the top of the building blue with crayons. This is the sky. Plus the green lawn and enthusiastic audience. Then do it, draw a green lawn around the dancers with crayons, cut out eight or nine children in magazines and paste them around the lawn respectively. You see, these children have different shapes. Some of them sit on the lawn with their heads up and their hands behind their backs. Some sit on the lawn with their hands on their thighs; Others are dancing around, as if learning to dance. How interesting it is! Next, it's time for this red mooncake box to go on stage. Cut it into a circle with scissors. This is a round sun. We stick it on the upper left of the cardboard, then cut some thin yellow paper strips and stick it around the sun. This is the light of the sun. The third step is to create an environment for dancers to dance. Here, buildings, spectators, the sun, etc. are cut and pasted; The sky and grass are painted by brush, and the combination of production methods reflects the author's innovative consciousness. This paragraph is the key part of the production, so the author writes it in detail, and the production process has a strong sense of hierarchy.
The main part of the screen has been completed, so don't relax, because there is still one last process-this section is a transition section, which is simple and smooth, and naturally connects the above with the following.
that's the fourth step: find out what's missing. The intense work just now may make us forget some small things, and small things are also very important. We need to calm down, find and supplement them to get the best results. By the way, isn't it more interesting to fly a few swallows over the heads of the audience? We can cut a few swallows of different sizes with purple glossy paper and stick them in the sky above the children's heads; Also, there should be trees on campus. Let's cut a big trunk, stick it on the lower right corner of the cardboard, and then stick it into branches with yellow paper strips. Where are the leaves? Wouldn't it be wonderful to stick the leaf specimens we made in science class to the branches? Oh! A big tree was made again. Look, is the campus life in the painting strong? Ouch! I forgot, how can there be no music at the dance? Got it! We can use watercolor pens to draw a string of staff notes on the lawn. The flowing music is euphemistic under the blue sky. The fourth step is to find out what is missing. The young author decorated the picture with swallows, trees and music. These swallows, trees and music used for decoration seem to be handy, but in essence, the author wasted a lot of thoughts to make them serve the theme of painting well and make the scene more campus life. Finding out what is missing reflects the rigorous scientific spirit of the young author.
In this way, an "exquisite dance on campus" has been made. There are people here who have things, feelings, scenes, movements and stillness, and even I can't help but admire them. Students, look, how did I do? You all say yes, then you should do it quickly. 3. Write a composition about small production
My small production
I have done many small productions, among which my most proud work is the tumbler.
The materials needed to make a tumbler are: an egg, a small awl, a box of watercolor pens, a piece of red cardboard, double-sided tape, fine sand and wax. First, stick a small hole in one end of the egg with a small awl, pour out the egg white and yolk slowly, and then rinse it with clear water. Next, put some fine sand in the eggshell and drop a few drops of wax to solidify the fine sand together. Fold a cone-shaped hat with red cardboard and stick it on the egg shell with double-sided adhesive. Finally, draw on the face of the egg shell. It's hard to draw on eggshells! I first draw a pair of watery eyes on my face with a watercolor pen, and then draw a nose and a small cherry mouth. It's finished. If you look at it carefully, it's really "good looks". I began to check the performance of the tumbler, shook it and stood up again. I shouted excitedly, "Success!" Every time I see this tumbler, I feel a sense of accomplishment.
It also gives me the spirit of learning that a tumbler is not afraid of difficulties and setbacks and never falls down. 4. 3 words composition about small production
Today, when the teacher assigned homework, every student was asked to make a "small production" at home on weekends.
When I got home, I began to think about what to do. Suddenly I saw an empty mineral water bottle on the opposite table, so I had a brainwave and thought, can I turn this bottle into a vase for arranging flowers? So I told my father the idea, and my father agreed and said it was a good idea. First, he helped me cut off the mouth of the empty bottle with scissors, and then he gave it to me to do. The first thing I did after I took the scissors was to cut the top half of the bottle into a belt about one centimeter wide in the vertical direction, and then roll the plastic belts out into spiral petals by hand, and then beautify the bottom half of the bottle. Stick beautiful patterns cut from New Year pictures on the bottle.
I'm going to start making flowers. I'm going to make a flower core with plastic paper first, and then insert a long plastic tube in the middle of the flower core. I draw two petals on white paper first, then paint the petals with my favorite color and stick them next to the flower core, then cut them into leaves with green gold paper and stick them under the flowers, and then repeat the previous method to make flowers with different colors. I'll * *. Finally, the flowers are made into vases first, and such a small production-vase is completed. This small production looks simple, but it is really not easy to do. I spent more than three hours before and after.
In this way, a beautiful vase is finished. 5. Writing and making composition

Four hundred words in grade four < P > Today, the teacher left us a manual class assignment to develop our own hands-on ability to make a small production. I went home, thought for a long time, and finally found inspiration on TV, so I decided to make one (whatever it is). So I started the production process.
First of all, I found all kinds of materials needed for production, and got busy (what to write here, such as origami, pasting, etc.). When I was making the key steps, I encountered difficulties, so I asked my father for advice, and under his careful guidance, I was able to successfully complete my work, and a sense of accomplishment came to me. The next day, I brought my little production to the class, and my classmates kept asking me questions. I was extremely proud. (Expand yourself)
Later, the appraisal results came out. My work didn't win the prize, but it was rated as excellent, but I was not discouraged, because I saw that some students' works were really exquisite, and even as a competitor, I couldn't help praising them. I hope I can have a chance to communicate with them, learn from each other and make progress together.
conclusion (almost, 3 words)
ah! So tired, adopt it! Hand-made composition
What is the happiest thing in life? Some people will say sleeping, some people will say studying, and some people will say playing games. And I think there are many happiest things in life, among which doing manual work is what I think is the happiest thing!
today, I'm addicted to manual labor. I made a small bookmark. If you can't do it yet, you can make a small bookmark with me. The materials you prepared are: greeting cards, glue, brushes, rulers, scissors and red silk thread.
First of all, I chose a greeting card with an aerial image of China. First, I cut out the part with an aerial image of China, cut it into a shape similar to that of a small wooden door, and then cut all the corners into circles. Why do I have to choose a greeting card with space pictures? That's because learning should be as aggressive as the space shuttle, so as to have "combat effectiveness". )
Then, I cut out a little girl from other greeting cards and put her on the top of the "door", which added a lot of color to this bookmark. I also cut a dialog box that we usually use for conversation from the remaining greeting cards. I wrote the word "Come on" in the dialog box, because learning is to be promoted step by step, and we should keep coming on. Then I cut out a puppy from the greeting card and put it on the back of the bookmark, because this year is the year of the dog! I also posted two small candies in the lower right corner, because learning should be fun and full of sweet smiles! In fact, this is also the inspiration I got when I watched the teacher give us a demonstration and put a bunch of flowers on the bookmark. )
At this point, my "great project" has been completed by more than half, and I looked at my classmates when I was glad. Everyone is working in full swing, and some students are constantly borrowing.
