Composition on tur waste into treasure 1

Disposable chopsticks are one of the most common items in our daily life. After use, we throw them into the trash can. Have you ever thought about turning useless disposable chopsticks into treasure? Recently, our class held an activity-disposable chopsticks turn waste into treasure!

This activity is a group of four people. A week later, it will be exhibited in the class. After the discussion in our group, we decided to make a set of tables and chairs model. And the heavy responsibility of production falls on me.

After eating a hearty lunch on Saturday, I got busy: first, I made a small chair, and I set the length of the chair as 4.5 cm. After measuring the length with a ruler, I marked it with a knife, and then cut it bit by bit with an art knife. Although the quality is good (both ends of the cut chopsticks are smooth), the speed is very slow. So, I'm going to use scissors to cut, which is sure to be fast, but then, a new problem arises: the quality is not good again, and the two ends of chopsticks are not smooth and uneven at all. Alas! what can I do? I racked my brains, but I couldn't think of anything. Suddenly, an idea flashed through my mind! Yes, I have already started. Why didn't I think of that? Cut with scissors first, and then trim the sides of chopsticks with a utility knife. Isn't that enough? I can't help laughing at my good idea to myself. After one chopstick was made, I made three more, and then put the four chopsticks together and glued them together. Thus 1 chair surface was completed, and I was really flattered to see the first step after I made it. But the following difficulties are even greater. The next step is to install the chair legs. You know, one side is composed of a semicircle, which is uneven. The contact area is very small, and it is very difficult for the chair feet to stand on it. I set the length of the chair foot as 2 cm. After correction, I used glue to drop a drop on the contact surface of the chair foot. Then I pressed it tightly with my hand, never relaxing, and kept blowing at the contact point. It took twenty or thirty seconds to assemble a chair leg. It took quite a long time to complete the matching of four chairs. Finally, I didn't finish eating the table. I secretly cheered myself up: "Come on! One more thing, it will be over soon! " I stretched myself and got busy again. I thought about it and decided to fix the length of the table to 8 cm and the width to 10. After half an hour of "fine construction", a table was finally completed. However, when I look at the table from left to right, the more I look at it, the more uncomfortable it becomes. Just destroy it, and then rebuild it carefully and make a small table again. This time, the more I look at it, the more pleasing it is. Alas! I am really a child prodigy! Ha ha ha ha ... hey hey! Sorry, blow your own horn.

In the process of making, how many times I almost broke the model that was about to be completed because of impatience; How many layers of glue have I got on my hand? How many times did the model fall apart because it was not glued properly? ...

Disposable chopsticks can also be made into many things, such as small lanterns, heat insulation frames, rattan frames and so on. You can try it if you are interested! Surprise is waiting for you!

Combination 2: Turn waste into treasure

"Oh, how about selling it to me cheaper, 4 yuan?" "No, I'm already losing money." ..... In laughter and bargaining, we started the long-awaited flea market.

The students brought a dazzling array of things. Some people brought toys, some books, some people brought their favorite decorations, some people brought delicious snacks … I also brought many toys and comic books myself.

At first, everyone went to other classes and booths to find what they liked, and I forgot to bring money! Well, I have to "wait for the rabbit" at my booth first. Just when I was desperate, a man came to my booth. I was ecstatic to see this client. The customer looked at it and asked, "How much is this monopoly?" I said happily, "Not expensive, 15 yuan will do." After listening, he said impatiently, "Just 10 yuan." I thought about it and said, "All right." So he smiled and handed me 10 yuan, and I finally earned my first bucket of gold.

The flea market is over, everyone bought their favorite things, and I bought a lot of good things myself. Each of us is also very happy, because we have turned all the things we cried for our parents to buy into treasures and sold them.

Come to think of it, who hasn't seen something we like before and then cried for parents to buy it? If our parents don't buy it for us, we will be angry. Maybe we just want to buy it for a while, and we haven't thought about what will happen to this item in the future. Maybe this item will be thrown in a dark corner in the future. Maybe it will only be thrown into the trash can, and no one will find it with the garbage that people throw away. Instead of having such a tragic ending, why not bring it to more people who like it in some way?

If we observe carefully in life, there are actually many things we buy on a whim. If we turn waste into treasure, we can bring happiness to more people and protect our planet.

Composition three turns waste into treasure

Cherishing resources is the responsibility of all of us, and patriotism is the obligation of everyone in China. From now on, we should cherish every drop of water and every inch of land.

In the past, there was a piece of land in my garden full of weeds. In summer, dad piled the harvested wheat straw on it; In winter, grandpa put cotton and firewood there, littering and disorganizing. Once, I asked my mother, "Mom, why not plant some flowers or big trees?" Why do you have to plant grass here? Grass is neither beautiful nor fruitless. ""In the past, there were seven poplars growing on this land. When our house was built, it was used in the house. If you don't take care of it for a long time, it will grow grass. "Mother looked at this wasteland, as if remembering the past, and said meaningfully," Let's clean it up today and let it shine again, shall we? " I excitedly said yes, you get the sickle, and we will pull the grass together. "Mom seems to have recovered for a long time and said with a smile." Yes, yes. "I am happy to promise, quickly to find a sickle.

A small piece of land, my mother and I quickly cleaned it up. We planted several kinds of strawberries on this land, as well as cucumbers, beans and watermelons. A few days later, my mother bought two apple trees in the market and planted them on the trees. I think I smell red apples.

In the warm spring breeze, in a few days, strawberries germinated, and cucumbers, beans and watermelons also poked their heads out to explore this wonderful world. I am so happy that I will come and enjoy the fruits of my mother's labor as soon as I have time. My mother and I often water and fertilize them, and care for the little buds carefully, just like protecting the little life. The weather is getting hotter and hotter, and the strawberries actually bear fruit, first green, then red. I picked a strawberry and chewed it in my mouth. There are sour, sweet and sour. It's delicious. At this time, cucumbers and watermelons also have yellow flowers. This is to open your eyes and enjoy this beautiful world. I don't know when bees and butterflies came to join in the fun. They danced, teased all kinds of flowers and played.

The hot summer has finally come, and my long-awaited watermelon is finally ripe. Mother picked the watermelon, washed it first and then cut it with a kitchen knife. I think watermelon must be very painful because it is bleeding. Red water flows out of its body, revealing red "meat" and black seeds. "Have a piece and taste it. What do you think?" My mother's words interrupted my thoughts, so I quickly grabbed a watermelon and put it to my mouth and took a bite. How sweet!

Cherish resources, love your country and your hometown, and start from your side. Cherish the land, not only add luster to the motherland, let the land glow with vitality, but also have the harvest of labor, how good!

Composition four turns waste into treasure

I recently read an article in a book that Germany uses garbage incineration to generate electricity. Because there was not enough for them to burn, they imported a lot of rubbish. Garbage used to make people laugh at it, but now it is skillfully used. Turning waste into treasure is really wisdom.

The morning breeze slowly brings a bit of comfort. Just after drinking a bottle of Anmuxi, I was about to throw it into the trash can when suddenly an interesting idea came to my mind-why not convert it into a homemade pen container? Thinking of this, I quickly opened the desk drawer and took out the knife in the toolbox, ready to show my talents.

How to operate? Sitting in front of the "console", I suddenly had a flash of light-first open a few "small windows" for the bottle! I carefully picked up the knife and used its blade to draw the outline of a "small window" within a quarter of the bottle. This time I drew a circular outline. After drawing the outline, poke a small hole in the line first, and then cut the whole piece along the outline. As a result, a hollow circle with even lines appeared on the bottle. This box is used to put black pens.

Next, in the same way, I cut a heart-shaped and a square hollow pattern on the front and back of the bottle respectively. These two squares are used to put pencils and rulers respectively. In addition, I specially cut a small rectangle as wide as my eraser on the right side of the bottle. Why by width? Because I consider that the length of the eraser will get shorter every time I wipe it. If I cut it according to the length, it won't be suitable for a while.

After the pen container is finished, I can't wait to put what I want into it through the grid. When they are all seated, at first glance-how beautiful! Frankly speaking, it's not worse than the one bought in the mall!

After a while, I turned the bottle I was going to throw away into a pen container for my use, and it didn't cost me a penny, and it also saved the energy consumed by making pen containers in the factory. This time, I really realized the utility and fun of "turning waste into treasure". It not only brought me happiness and a sense of accomplishment, but also improved my practical ability. I looked at the exquisite pen container I made, and I was filled with emotion.

Composition five turns waste into treasure

The day before school started, it rained continuously. It's nearly noon after checking my homework and packing my schoolbag. I found my mother and grandmother busy preparing lunch in the kitchen. Suddenly found my desk, dirty and messy, full of eraser mud and waste paper. So I decided to clean up the battlefield myself. I brought the biggest trash can in my house and threw the waste paper balls in one by one. In the blink of an eye, a big trash can is full, which can't meet my needs completely. I have too much rubbish. Just when I was worried about what to do, grandma called me with a delicious lunch. "MengMeng, how did you throw away all the paper? This paper is a treasure, it can be used to sell money and buy useful things, and it is environmentally friendly, killing two birds with one stone! " Grandma said seriously. "Yes, grandma! You are really my great strategist! " I immediately suddenly realized, "I don't know, what's the selling price now?" How much is a catty? "My mother heard my conversation with my grandmother in the kitchen and said with a smile," My father's company just sold sorted newspapers and paper heads years ago, and the purchase price was 1 yuan a catty. The premise is that it is neatly placed. "After listening to my mother's advice, I immediately put waste paper and newspapers in the trash can, folded them one by one and piled them up according to the size of the paper. Half an hour passed, and another hour and a half passed. My mother joined my tidying team, and my room was clean and tidy. There are four piles of redundant books, newspapers and waste paper, which are arranged neatly like small peaks. " Mom, I think I will be a monopolist this afternoon. How many pounds do you think this is? How much can I sell it for? I want to buy super easy-to-use mechanical pencil, and I want to buy beautiful colored paper ... "I described my purchase plan happily.

After lunch, my mother and I immediately drove the packed four Bao Shu to the recycling station near our home. The first scale actually showed "16kg", and the boss really gave me 32 yuan money as promised. I am sweating profusely. Although it is raining in Mao Mao outside, my mood is sunny. Today, I finally figured out the relationship between gold and KG: 1KG= 1 kg =2 kg.

It turns out that the knowledge of mathematics is floating around us, and children who are interested can use it immediately as long as they observe it carefully. Only by working hard and using our little brains can we reap fruits and be happy.
