Content of sci-tech handwritten newspaper

I believe many people have written handwritten newspapers at school. Now let's take a look at the contents of the scientific handwritten newspaper!

Scientific and technological manuscripts

Technology is everywhere, and its benefits are often reflected in our lives. Telephone, let the people of the whole country speak freely; Refrigerator, let human realize the dream of long-term preservation of food; Airplanes enable people to save time and get to their destinations faster. Can't all this reflect the convenience brought by science and technology to mankind?

Since the first industrial revolution, there have been countless scientific and technological achievements. For example, Watt invented the steam engine in the first scientific and technological revolution, which gradually abandoned human labor, greatly improved the labor force and entered age of steam. Edison invented the electric light in the second scientific and technological revolution, which was a great milestone in the utilization of electricity by human beings. Since then, age of steam has entered the era of electricity. The third scientific and technological revolution invented a series of high-tech products, such as computers and mobile phones. The appearance of these products marks that we have entered the information age, which is the largest and most far-reaching scientific and technological revolution in human history so far.

The amphibious underwater train is fixed on the subgrade of the elevated track underwater railway with the help of guide wheels, and the train can run smoothly in deep water with the help of vertical and horizontal stabilizers used by submarines. The underwater train is equipped with an advanced linear engine to drive the train to run fast in the water.

In the next few decades, we may emigrate to other planets in the solar system. NASA is preparing to implement several Mars programs, and the expert group believes that humans will land on Mars around 2022. The permanent lunar base can be used as the launch base for this space program. But humans still have a long way to go to perform outside the solar system.

Traveling in the solar system, handwritten newspaper materials

I had a good dream when I slept at night. I dreamed of traveling in the solar system with the Monkey King. ? In my dream, Wukong came out of nowhere and ran up to me, smirking and asking, Do you want to see things in space? ? Of course I would. So, Wukong took me into the air. ?

The wind blew through my ears. When he was about to fly out of the atmosphere, Wukong pulled out a hair and turned it into two big bubbles filled with oxygen. Each of us got on the bus and immediately felt as smooth as breathing on the earth. Head on, we saw the moon. The surface of the moon is bare, and there are large and small pits everywhere. If there are legendary Chang 'e and Moon Rabbit, they must be very lonely. Looking back, I found that the earth is like a blue crystal ball suspended in space, which is very beautiful.

Scientific ideas and handwritten newspaper materials

Some time ago, several big brothers of a group of British space enthusiasts put a piece of potato and beef pie on a weather balloon and sent it to the stratosphere of the atmosphere. The stratosphere is hot and cold, approaching the distance of space. The weather balloon is equipped with a camera, which can take pictures of pies. These bosses want to see if the molecular structure of the pie can be changed at an altitude of 30 kilometers. After a wonderful and thrilling space trip, the pie returned to Britain safely, and the bosses found that its taste was no different from that of ordinary pie. Whether his molecular structure has changed quietly is still under further analysis.

Spread the wings of science and fly the dream of science.

Reconnaissance satellites are satellites that steal military information. Standing high, seeing far, listening and eavesdropping, he is a veritable super spy. Satellites use reconnaissance equipment, such as photoelectric remote sensors or radio receivers, to scout, monitor or track targets from space orbit in order to collect information of ground, ocean or air targets.

The electromagnetic wave information radiated, reflected or emitted by the target collected by reconnaissance equipment is recorded and stored in the return cabin with film and tape, and recovered on the ground; Or transmitted to the ground receiving station in real time or in time delay by radio, and then processed by optical equipment and electronic computer to extract valuable information from it.
