One morning when I went out to school, I suddenly found a gecko on the wall in front of my house. Its hands and feet are tightly sucked on the wall, so I can easily climb up the wall without falling down. I think I can design a kind of shoes like gecko's hands and feet. This kind of shoes is called "Gecko Shoes".

This kind of shoes is very convenient. Workers don't need to bring safe and unreliable ladders when painting walls and decorating. All you need to do is put on a pair of very safe "gecko shoes" and you can start work. It can not only attract like a gecko, but also lower your center of gravity and keep you stable, so that you can brush backwards and not fall off. Press the red button on the left shoe to move freely, and then you can get off. When I grow up and invent this kind of shoes, I will definitely give them to the workers and masters!

The infinite scenery of nature gives us infinite inspiration. We should observe the scenery in nature more and give birth to countless fantastic ideas to benefit mankind!

How to write my invention composition should be about 350 words, homework help. My invention is a little girl who loves to invent. No, I'm fiddling with my new invention again. I want to make a chocolate-flavored "drink" this time, but I can't drink it because its pigment material is ink. Now, let me introduce my production process in detail. First, I poured half a bottle of water (tap water), and then I began to drink. Then I put half a chocolate and half a sugar, and then I stirred it with a wooden stick. Finally, put a corn-flavored jelly, soak it for about half an hour, or even longer, and take it out with a fork, so that it has the smell of corn. All right! The whole thing is basically completed, and it will be done in the fermentation period for one night! What are the bad consequences of drinking this new drink? I haven't found it yet. I'm going to try it. However, I declare that it is by no means poison, but my masterpiece and my second invention. The first kind is sour grapes, with grape juice and strawberry juice, which tastes good. Similarly, I haven't tried it, and I don't know the result. I hope it's just an animal drink, and it won't have any side effects. If it can sell well in the pet market, my invention can be regarded as an achievement. O(∩_∩)o I hope I can help you! O(∩_∩)o Please give a compliment or adopt it in time. Thank you very much (*^__^*)

Last night, I had a dream that I was in the twenty-third century.

I looked around and found an uncle waving to me. I hurried over. He saw me coming towards him and said to me, "Hello, little friend, you must be confused, right?" Take it easy. I brought you here with a transporter. I want to show you my newly invented skirt. I'm Dr. Li.

"Say that finish, he took me into a laboratory.

When I walked into the laboratory, I saw a fluorescent yellow skirt. There are three little flowers on the skirt. The first one is blue, the second one is yellow and the third one is green.

I asked Dr. Li doubtfully, "Did you invent this skirt?" Dr. Li naturally replied, "Yes.

"I added," except for three little flowers, it's no different from an ordinary skirt.

"Dr. Li said," don't underestimate these three little flowers, they have a great role! Look at this little fluorescent yellow flower. It plays a role in emitting light.

When you want to join a tour group or need lights at night, just press the fluorescent yellow flower and the skirt will emit fluorescent yellow light.

""How can that skirt shine? " I asked.

Dr. Li replied, "that's because this skirt has been absorbing light during the day." When you press that little flower, the skirt will release the light absorbed during the day, so the skirt will shine. "

"I said," Oh, so that's it! In this way, this skirt goes along the road. Isn't this saving the strength of the country? " Dr. Li said: "This is one of the reasons why this skirt can make everyone like it.

"Dr. Li said," This skirt is also waterproof! If you press the blue flowers, this skirt will make you float in the water.

""What the hell is going on? " I asked.

Dr. Li said, "Because when you press the blue button, your clothes will be filled with gas and lift you up like a life jacket.

""wonderful, wonderful! "I can't help praising it.

"Wonderful, wonderful!" My mother came to me and said it was a dream. I thought about the skirt I saw in my dream several times. Finally, I made up my mind that I must invent this skirt when I grow up.

Composition of bat inventing radar 350-word composition of bat inventing radar Many inventions of human beings are based on animals. What I know is: from dragonflies to airplanes, from small fish to submarines, from car accidents to the preciousness of life.

I am also a primary school student who loves learning. I have made many discoveries in my life, such as thinking of radar from bats.

One night, I was in the corner of my house and something like a little mouse was crawling there. I looked at it and it jumped down and squeaked. I looked at it again.

It turned out to be a little bat. I put it in a house with a lot of money and some bells. The bat stayed in it for a long time without making any noise. I think the radar on the plane may be copied from bats! I wonder why it is difficult for bats to touch anything. It turns out that bats don't need eyes to walk at night, but only use their ears and mouths to find their way. First of all, they make a sound from their mouths, which is called ultrasonic waves. Whenever they meet obstacles, this sound will be reflected back to their ears, so that bats will not meet obstacles. I think bats are really smart animals, so I thought of the radar invented by humans. The plane is equipped with radar, so as long as they emit ultrasonic waves, they will encounter obstacles.

I think of radar from bats, and there are still many secrets in nature waiting for us to explore.

So I will study hard and invent something great when I grow up.

Watt's invention composition is about 350 words. Students, you have all heard of Watt.

Today I will introduce Watt's early steam engine to you.

Watt is a scientist with fruitful scientific research results. He has the courage to explore and is very interested in invention.

When he grew up, when he was repairing the steam engine, he found that the steam engine at that time had a lot to improve, so he decided to make a steam engine himself.

After repeated experiments and numerous setbacks and failures, he finally built a steam engine with excellent performance.

Students, after listening to this story, do you have any experience and feelings? I know.

I am aware of scientists' unremitting spirit and determination to succeed.

This little story makes me feel that the efforts of scientists have helped us. When we do something, we must experience setbacks and failures. If you have no determination and perseverance, then you can't do anything. If we have determination and strong fighting spirit, no one can match us, because we are the best.

How good would it be to invent a smart pen? There are many kinds of pens in the world, and the number is countless. I love fantasy and want to invent a multifunctional pen.

This pen looks like a small rocket, and the main color is silver.

There are four buttons on this pen: red, white, blue and green.

The function of the red button is to make the microcomputer in the pen change the original elements of the pen, thus replacing the colors of the pen, such as red to blue, blue to green, green to yellow, yellow to black, black to red and colorful.

This can save time for changing pens.

The function of the white button is to allow the microcomputer to change the refill and miniature eraser at will. If you make a mistake, you don't need an eraser. Just press the white button, and you can eliminate the typo.

This can save time in finding an eraser.

The function of the blue button is to let the microcomputer record its own information.

Even if you lose this pen, the person who finds it will press the blue button and get your message, and it will be returned to its owner.

So I'm not afraid of losing my pen.

The function of the green button is to let the microcomputer record what the teacher said so that we can review it better.

Maybe the current technology can't make such a pen, but I firmly believe that as long as we study hard and work hard, our dreams will come true!

One Sunday, I finished the homework assigned by my teacher and picked up a book at home to read when I was idle.

Suddenly, I saw the lid of the kettle keep jumping. I poured water into the thermos, and suddenly an idea flashed through my mind. If the water boils and I can't see it, won't the kettle melt? Our family once burned a kettle because the whole family was not at home at that time.

I have to find a way to prevent the kettle from melting. I had a brainwave. If you tie a bell to the lid of the kettle, then tie a small rope to a nail, and then nail the nail to the wall, won't the bell ring when the water boils? I'll do it first and see if I can succeed. I mean it. I'll do it in order. First, I will tie the bell to the pot cover, then nail the nail to the wall, and then I will hang a thin and long rope on it. I put the water in the pot. After a few minutes, the bell really rang and the wire was not broken. I jumped up and down happily and told my father my little invention. Dad said with a smile.

"Hearing my father's praise, my heart is as sweet as honey.

Since then, my kettle has never melted.

From the case of Home.sanwen8.cn, I understand a truth: It is not easy to achieve excellent results, and it takes hard work.

Whatever you do, you can't give up halfway. You will succeed as long as you are patient.

Scientists have done many experiments with frog eyes.

According to the frog's eyes, scientists invented the "electronic frog's eyes".

Because frogs have strange eyes, they are keen to see moving things, but they "turn a blind eye" to static things. Scientists got inspiration from frog's eyes and invented "electronic frog's eyes".

This kind of "electronic frog eye" can accurately identify objects with specific shapes like real frog eyes.

After installing electronic frog in radar system, the anti-jamming ability of radar is greatly improved.

This radar system can quickly and accurately identify aircraft, ships and missiles with specific shapes.

In particular, it can distinguish between true and false missiles and prevent false confusion.

Electronic frog eyes are also widely used in airports and traffic arteries.

At the airport, it can monitor the take-off and landing of aircraft, and give an alarm in time if it is found that the aircraft is about to collide.

On the main road, you can direct the vehicles to prevent them from colliding.

From this, I think there are many things in nature that we need to learn. As long as you observe carefully and think carefully, you can get greater gains.

...

I want to invent something through animals. Scientists have invented many things from animals and plants! I also want to learn from scientists.

Gecko's hands and feet are very attractive. It can easily climb the wall without falling.

I want to design a kind of shoes like gecko's hands and feet. The name of this kind of shoes is "Invincible Suction".

Very convenient. Workers don't need to bring ladders when painting walls. They just need a pair of shoes with "invincible attraction" to start work. It can not only absorb energy, but also reduce your weight. Even if you paint the wall upside down, it won't fall off. There are two buttons on the right side of the shoes. Press the green button, it will let you move up and down on the wall without falling off. Press the red button to get off.

Is it convenient for you? When I really invented "invincible suction", I will definitely give it to those workers who wash the ground and build houses.

Nature is really a good teacher for human beings. I will carefully observe the things around me and design more gadgets.

The ballpoint pen I want to invent brings convenience to mankind, but what can ballpoint pen do besides writing? I want to invent an intelligent ballpoint pen. If you write a wrong word, it will automatically change the correction fluid to help you correct the typo. If you are unhappy, it will automatically tell you a joke to cheer you up.

There is a small translation machine in it, which can translate other languages into Chinese and into what animals and plants say, so that we humans can communicate with animals and plants.

This pen also has a camera to see what you are thinking.

It will present what you think in front of your eyes through the display screen.

In addition to these functions, he can generate electricity automatically. In the process of writing, it will automatically generate electricity and save the excess electricity.

How's it going? My smart ballpoint pen is not bad.

Edison invented the electric light. Before the electric light appeared, kerosene lamps or gas lamps were widely used as lighting tools.

Because this kind of lamp burns kerosene or gas, the black smoke is very thick, the smell is pungent, and it is inconvenient to add fuel, so the lampshade is often scrubbed.

More importantly, this kind of lamp is easy to cause fire, which will lead to great disaster.

For many years, many scientists have tried their best to invent a safe and convenient electric light.

/kloc-At the beginning of the 9th century, a British chemist made the world's first arc lamp with 2000 batteries and two carbon rods.

But this kind of lamp is too strong and can only be installed in streets or squares, which is not used by ordinary families.

Numerous scientists have racked their brains to make a cheap and durable household electric light.

This day has finally arrived.

1879101October 2 1 day, an American inventor finally lit the world's first electric lamp with practical value after long-term repeated experiments.

Since then, the inventor's name, like the electric light he invented, has entered thousands of households.

He is Edison, who is praised as "the king of invention" by later generations.

1847 In February, Edison was born in Milan, Ohio, USA.

He has only studied in school for three months in his life, but he is studious and diligent in thinking. His invention has created many achievements 1000, such as electric light, phonograph and movie camera, and made great contributions to mankind.

When Edison 12 years old, he was addicted to scientific experiments. After his tireless self-study and experiments, at the age of 16, he invented an automatic telegraph that sends signals every hour.

Later, the automatic counting machine, the first practical typewriter, double and quadruple telegrams, automatic telephones and phonographs were invented one after another.

Edison was not satisfied with these inventions. 1in September, 878, Edison decided to attack the fortress of electric lighting.

He read a lot of books about electric lighting and made up his mind to make cheap, durable, safe and convenient electric lights.

He started the experiment with an incandescent lamp.

Put a small piece of heat-resistant thing in a glass bubble, and when the current burns it to a white-hot level, it will give off heat and glow.

His first thought was charcoal, so he put a small piece of charcoal wire into a glass bubble, and the glass bubble broke as soon as it was electrified.

"What is the reason?" Edison picked up the carbon wire broken in two and looked at the glass bubble again. After a long time, he suddenly remembered: "Oh, maybe it's because there is air in it. The oxygen in the air helps the carbon wire burn and makes it break immediately!" " So he used his own hand-made air extractor to extract the air from the glass bubble as much as possible.

Once it is electrified, it will not go out immediately.

But eight minutes later, the light went out.

In any case, Edison finally found that incandescent lamps are very important in a vacuum, and the key is carbon wires, which is the key to the problem.

So what kind of heat-resistant materials should we choose? Edison thought about it. Platinum has the highest melting point and strong heat resistance! So Edison and his assistants tried platinum several times, but this kind of platinum with higher melting point prolonged the luminous time of the electric lamp a lot, but it was still not ideal to turn it off automatically and then glow from time to time.

Undaunted, Edison continued his experimental work.

He tried various rare metals such as barium, titanium and indium, and the results were not very satisfactory.

After a while, Edison made a summary of the previous experimental work and wrote down all kinds of heat-resistant materials he could think of, a total of 1600.

Next, he and his assistants began to test 1600 kinds of heat-resistant materials in different categories. You can try it, and platinum is the most suitable one.

Due to the improved air extraction method, the vacuum degree in the glass bulb is higher and the life of the lamp is extended to 2 hours.

But this kind of platinum lamp is too expensive. Who wants to spend so much money on a light that can only last for two hours? The experimental work fell into a trough, and Edison was very upset. In a cold winter, Edison sat by the fire and looked at the burning coals. He couldn't help saying to himself, "Charcoal …" The charcoal bar made of charcoal has been tried. What should I do? Edison felt hot all over, so he pulled down the scarf around his neck. Seeing this scarf made of cotton yarn, Edison suddenly had an idea in his mind: Yes! Cotton yarn has better fibers than wood. Can you use this material? He quickly tore off a cotton yarn from his scarf and baked it on the fire for a long time. Cotton yarn turned into charred charcoal.

He carefully put this carbon wire into the glass bubble, and after testing, the effect is really good.

Edison was very happy, and then he made a lot of carbon filaments from cotton yarn and did many experiments in succession.

The life of the light bulb was extended by 13 hours, and then it reached 45 hours.

As soon as the news spread, it caused a sensation all over the world.

The share price of London Gas plunged, and the gas industry was in chaos.

People have a hunch that lighting gas lamps will soon become history, and the future will be the era of electro-optics.

Everyone congratulated Edison, but Edison didn't look happy at all. He shook his head and said, "No, we have to find other materials!" " ""What, you haven't worked for 45 hours? " The assistant asked in surprise.

"no! I hope to open 1000 hours, preferably 16000 hours! " Edison replied.

As we all know, it is good to shine for more than 1000 hours, but what materials can we find? Edison knew what he was doing.

According to the nature of cotton yarn, he decided to look for new materials from plant fibers.

So, the marathon experiment began again.

Edison experimented with all kinds of plant materials he could find, even horse mane, human hair and beard were used for filament experiments.

Finally, Edison chose bamboo as a plant.

Before the experiment, he took out a bamboo and observed it with a microscope. He jumped for joy.

So, put the carbonized bamboo filament into the glass bulb, and after electrifying, the bamboo filament bulb lights continuously 1200 hours! Edison finally breathed a sigh of relief, and his assistants congratulated him one after another, but he said seriously, "There are many bamboos in the world, and their structures are different. We should choose them carefully! " Edison's scientific attitude of pursuing perfection deeply touched him, and his assistants volunteered to visit various places.

After comparison, a kind of bamboo produced in Japan is the most suitable, so it is imported from Japan in large quantities. ...
