About the hand copied newspaper made by science and technology, how to do the hand copied newspaper

A hand-copied newspaper is another form of newspaper that can be circulated, viewed, and posted. In school, hand-copied newspapers are a good form of activity in the second classroom, and PPT has the same effect, but unlike PPT, hand-copied newspapers are purely handmade, only one page, so the content should be reasonably arranged. Hand-copied newspapers, like blackboard newspapers, are also a mass propaganda tool.

It's the equivalent of a miniature version of a blackboard newspaper.

The brief content of the scientific and technological hand-copied newspaper is as follows:1. Scientific and technological innovation is endless.

2. Science and technology education should start from the child.

3. Scientific and technological innovation and popularization of science are the common cause of the whole society!

4. Today's little inventors, tomorrow's big scientists.

5. Carry forward the spirit of science, popularize scientific knowledge, and disseminate scientific ideas and methods!

6. Everyone participates in the science and technology festival, and I am the master of my science and technology festival!

7. As modern primary and secondary school students, we should get closer to science, explore new knowledge, make our lives better, and learn science seriously, love science, and make science make our lives better.

8. Science mainly deals with unknown fields, and its progress, especially major breakthroughs, is unpredictable; Technology is working in a relatively mature field and can make more accurate planning.

9. The wings of science fly the dream of science.

10. Decorate life with innovation and integrate science and technology into ideals.

The development of science and technology has brought great convenience to our lives, and now from the previous carriage to the current reporter, from the original steam train to the current high-speed rail location, from the ancient clothes exchange to the current mobile phone payment, all factors have shown the change of the times, the development of science and technology, and the change of people's lives.

I think technology has brought a lot of convenience to the world, and the convenience of changing the world can be divided into three categories.

The first type of communication changes, we all know that ancient things are very inconvenient, what flying pigeon transmission is not only very slow and very easy to lose the new construction, resulting in a lot of tragedy, and then look at the current mobile phone computer, WeChat MMS is very fast, and there is no need to let people run around. It can be seen that the changes in communication have brought a lot of convenience to people.

The second type of traffic changes, I know from my father, he wants to go back to see his grandparents when he is working, it is very difficult, because the train has just opened at that time, so the train runs very slowly, often have to drive for several hours to facilitate what high-speed rail, subway, plane, car, etc., have made the original ten hours into the current hours, but also let those parents who miss their children, those who can't wait to reunite with their parents children children a little earlier.

The change of the third type of payment from the book I learned that people in ancient times were to take what they didn't want to find others, in exchange for what they needed, to modern times people gradually began to use currency to buy things, although currency is relatively simpler than the method of bartering a lot of things, but the currency is too easy to lose, some paper money is easy to tear, causing a lot of losses, and some lawless people use some means and hungry counterfeit money to deceive people, but since the mobile phone payment came out, These shortcomings and doubts are gone, mobile phones are more convenient than currency, you only need to take a mobile phone when changing jobs, and you don't have to worry about losing the money in your mobile phone, this is because modern smartphones have payment passwords, with passwords, the battle of beans steals yours'The phone can't take out all the money in the phone.

Technology makes life better, and its development is a earth-shaking change for people, and I hope that science and technology will go further and make our lives better.

Cigarettes are knotted. Wrap the outside of the cigarette tightly with cellophane, tighten the ends tightly, and then tie the cigarette in a knot so that it will not break or break.

If there is no cellophane wrapping, the pressure of the cigarette is concentrated in a few places when it bends, and it will burst there. The glass paper has a strong tensile force, and it distributes the pressure evenly throughout the cigarette, so it will not break. After untying the knot, you only need to straighten and flatten the cigarette to return to its original appearance.

Make a periscope.

To make a periscope, you only need two small square mirrors of the same size and a piece of cardboard. If your small mirror is ten centimeters long and seven centimeters wide, then you should prepare a piece of cardboard with a width of 4 7 = 28 centimeters. The length of the cardboard can be decided for yourself according to the conditions.

The cardboard is longer, and the periscope can be made taller.

Three parallel lines were drawn on the cardboard, each with a distance of seven centimeters, as shown in the diagram. Cut off the blacked-out parts. Use a knife to make a mark along the dotted line (be careful not to cut through).

Then, use the edge of the table to fold it so that it becomes a rectangular box, and Danfeng glues it with kraft paper.

Glue the small mirror with white tape as shown in the picture below (so that the angle between the small mirror and the long carton is equal to 45°). Two small mirrors are aligned in parallel. In this way, a periscope was made.

If the small mirror in your hand is less than 10 centimeters long, you can calculate the size of the carton according to the Pythagorean theorem, provided that the angle between the mirror and the carton is 45°. It's fun to use a periscope to ** the scenery outside the window, and you can also use it to hide and seek. Of course, periscopes were made primarily for scientific research and national defense.

Scientists use periscopes to observe the launch of rockets in the basement; When conducting atomic physics experiments, researchers use periscopes to observe dangerous experiments that are radioactive through a thick protective wall. When the submarine sails underwater, it must also use a periscope to observe the situation on the sea surface. <>

<> who invented the periscope is now impossible to find. The earliest ancient book in the world to record the principle of periscope is the Huainan Wanbi Technique in China in the second century BC. The book records such a passage: "Take a large mirror and hang it high, and put the water tray under it, and you will see the neighbors." ”

In ancient times, under the eaves of some ancient temples in the deep mountains of our country, a large bronze mirror is often hung obliquely, if a basin of water is placed on the ground within the temple gate, the mirror is aligned, this is made into a simplest periscope, and the sheep intestine path and passing pedestrians outside the temple gate will be reflected in the water.
