Science and technology, as the name implies, is science and technology. Everyone should be familiar with science and technology, because it is used and served by us and it is closely related to our lives. It not only gave me

Children bring us spiritual pleasure and physical comfort. In this rapidly developing society, science and technology represent a kind of spirit as well as a kind of strength. It represents an innovation and a text.

Ming. It is an important symbol to measure a country's comprehensive national strength, and science and technology occupy an important position in any field.

Science and technology are widely used, including military, biological and aerospace.

Technology has been integrated into life and enriched it. In the street, at home, in the classroom and in the shop, technology has brought convenience to people. It can be said that human beings created science and technology, and science and technology also created human beings, human beings and technology.

Are interdependent. Our food, clothing, housing and transportation are inseparable from technology. Let me take you into the wonderful life of science and technology.

Clothes make the man, and everyone needs clothes to dress himself.

Take a closer look at the clothes we wear. Acrylic, silk and pure cotton ... are slim, warm and healthy ... countless, which bring us warmth, comfort, health and happiness. And the production of these clothes is far from complete.

Without technology, let's talk about warm clothes, which can make you feel warm. In the cold winter, you can feel the warmth without wearing a thick down jacket and a thick sweater, just wearing a light and soft warm clothes.

Warm. You see, isn't this the convenience brought by technology?

Let's see what we eat. Now, we should pay attention to everything we eat, that is health! With the progress of society and the development of human beings, everyone is eating.

The concept of food has also changed, not only pursuing good taste, but also requiring food to be healthy and nutritious. Nowadays, many people eat high-tech foods, such as protein powder, calcium tablets and dietary fiber. These are all developed by scientific and technological personnel.

From the investigation. Today, we talk about a high-tech food: vegetable juice drink. Vegetables are an important source of vitamins and minerals and a guarantee of life and health. In terms of nutrition and health care, vegetables can provide comprehensive nutrition.

Nourish, prevent and even treat nutritional deficiency. However, because the taste of vegetables is not accepted by most people, scientists and technicians improved vegetables and made a delicious vegetable juice drink, which became ideal.

Future drinks.

Let's take a look at the most common material for building houses-cement. Cement is a brown-gray powder made of limestone and clay, which will harden when mixed with water.

Often. In recent years, with the development of new technology, functional cement has been continuously developed. There are many kinds, such as glass glue, light glue, rubber glue, sugar glue, color-changing glue and so on.

Cement has its own characteristics and is the crystallization of science and technology. Today I'm going to introduce you to a magical cement: color-changing cement. This kind of cement is not only an ideal building material, but also can be used to forecast the weather, and it also has "gas"

Like cement. "

It is called blue when the weather is dry; Once wet, it turns purple; If it rains, it will become a bright rose after absorbing water. It changed color because cobalt dioxide was added to the cement. Listen,

Isn't it amazing? In fact, this is also the surprise and convenience brought by technology.

Speaking of cement, let's talk about cars. Whether traveling or taking a bus, the car is a convenient and important means of transportation.

Perhaps the small technology you invented, after being modified and perfected by experts, has become a veritable scientific and technological product, and can also make great contributions to the future society and mankind.

Students, science and technology is a magical and great cause, which brings infinite joy and convenience to our lives, allowing us to understand, discover and create science and technology. I believe that technology comes from life, and life cannot be separated from technology. Let's use our wise eyes to discover technology!
