An essay on scientific and technological gizmos 10

My little inventionClass 4 (1) Lai Yun Instructor: Lu Lihua.

I'm a lively and cheerful little girl, and I love to use my brain. My little invention - "Household Three-proof Quantitative Grain Bucket" won the first prize of the 8th Municipal Science and Technology Competition and the third prize of the 25th Provincial Science and Technology Competition.

When the host shouted my name to announce that I had won, I was ecstatic, I had won! Brand new medals sparkled around my neck, shining like the sun. At this moment, my blood was boiling, and tears came out of my eyes with excitement.

Because I have won honor for the school, added glory to my parents, and added glory to Huiyang! At this time, I remembered the hard work of my instructor, Director Li Yibing, and I will never forget it. Standing on the podium, a pleasant ** rings in my ears.

From time to time, I will hear the voice of praise, and my heart is like eating a bucket of honey, sweet! When I learned that my work had been patented, I couldn't help but jump and my family applauded.

This success not only belongs to me, but also to my instructor, Director Li, who has given me a chance to succeed because of his patient guidance. This success has taught me that as long as you have perseverance, faith, and perseverance, you will definitely win!

In 2030, I found that the oil was gone, so I went to refill it.

On the way, I noticed that the noise from the car was harsh and distracting, and the exhaust fumes polluted the environment. When I went to work, I found that the paper I used to write on was very soft, and it was easy to scratch when I wrote.

When I got home, I started working on three things: a solar-powered silencer, a solar-powered refueling meter, and a solar-powered hard and soft meter. They are the size of a watch, with three functions linked together and seven keys on them; The top two are refueling type and refueling, anything can be refueled, the car can add oil, the watch can add electronics, and people can add strength; The middle two holes are silencing type and silencing, plus one hole, you just need to press the silencing button, a water injection will be sprayed out of the hole, after being sprayed by this water, there will be no sound, there is no noise in the car, no sound in the person, no noise in the camera; The following three are soft and hard, soft and hard selection, and light emission, whatever is exposed to this light will become soft or hard, the stone will become soft like bread, the paper will become hard, and you can't cut it with a knife, but you can still write and be very light.

These three things are convenient and affordable.

If the electricity is gone, it will remind you: "The electricity is gone, the electricity is gone." Until you hear it. At this time, you only need to put this watch into the matching solar safety electric baton, and after half a minute, there will be electricity.

At the same time, this watch also has the function of an ordinary watch, and it can watch TV.

The matching safety electric baton can be made bigger and smaller like a golden hoop bar. Press the button on the electric baton, and you can also use it as a police electric baton to catch thieves.

It's all just a fantasy, but in order to make it happen, I have to study hard.

When I'm at home, I always take the initiative to do whatever I can, such as washing dishes, mopping the floor, and wiping the table. What I am most afraid of doing is mopping the floor, a few houses are dragged down and my hands grind out blood blisters, cabinets, tables and other narrow places are not easy to mop, and they are not clean. Once, while mopping, I thought how nice it would be if I had a pair of mop shoes to wear on my feet and mop the floor!

So, I designed a mopping tool that was both lightweight and didn't bend over – the shoe flip-flops.

Production method: 1. The slippers should be larger than the shoes you usually wear, so that they can be easily worn on the shoes.

2. Use rag strips as mop strips on the soles of shoes, and nail a thick layer of plastic bottom on the mop strips, which is both waterproof and durable.

3. Use a cloth shell and a tarp to make an upper, and install a zipper on the back root of the upper, which is easy to put on and take off. Connect the upper to the sole and the slip-flop is ready.

My science and technology gadget essay.

Well, when I touched it lightly and fell to the ground, the lid immediately broke, and all the biscuits inside leaked out, which was very difficult to clean up. Also, if the biscuits are left for a long time, the biscuits will be easy to spoil, and I can't eat them, so I have to throw them away, so I hurt my brain, and finally thought of a perfect solution.

I don't know anything about cookies, but I still know a thing or two about boxes. The lid of the biscuit box is not tight because there is air in it, and the biscuit is easy to spoil, also because it comes into contact with air, as long as there is no air in the biscuit box. But how can I empty the air, when I opened the drawer to look for information, I opened the drawer and suddenly there was a gust of wind, by the way, make a small hole under the lid, and make a drawer-like thing on the side, as long as you keep pulling the drawer, the air will be pumped out along the small space, and the air in the box will be emptied, so that the lid will not fall off so easily, no matter how many cookies you buy are only put in such a box, you are not afraid of breaking.

And you don't have to remember how many times you have to use it to evacuate the air, you just have to keep pulling and pulling, and when you can't pull it, the air in it will be gone, and you don't have to worry about not being able to pull it out, just pull it gently.

How's it like, my tech everyday life gadgets are both practical and simple!
