100,000 Whys 10 fourth grade essays after reading

After reading it, you can first introduce some of the content of this book, and then write about what you have learned through this book.

Body. I really enjoyed watching "100,000 Whys" because it made me realize how small I was, the depth and wonder of the world. It seems to be close at hand, but yet out of reach.

Adults always say that the world is beautiful because there are many "whys". So I began to work hard for the "why" and dig out the mysteries of the world. One by one, "why" filled every station in my life.

The book is divided into six sections: My Animal Friends, The Wonderful Universe, The Mysteries of the Earth, The Amazing Nature, Rivers, Lakes and Seas, and The Kaleidoscope of Plants. And my favorite thing is the wonderful universe.

The universe is boundless, and there are many unknown stars for us to explore and excavate. How old do you know the universe? I know that astronomers have calculated that the age of the universe is about 12 billion to 15 billion years old, and the exact time is uncertain.

The Hubble Space Telescope measured the universe to be 13 billion 14 billion years old.

Do you know how galaxies come about? I know that most galaxies are formed by the gas clouds produced by the large ** that attract each other and install them. If gas clouds swirl around each other, spiral galaxies are created; If the gas clouds do not spiral, then all the gas clouds transform into stars, forming air-free stars ——— elliptical galaxies.

100,000 Whys took me into the universe, learned about the universe, and let me know the mysteries of the universe. It made me fall in love with galaxies and with this world full of mysteries. I love you, Universe!

Every "why" of Brother Lu is a part of the process of growing up, a golden key, a pair of dreamy and warm wings, a small sailboat in the ocean of knowledge, and a bosom friend who will never forget to accompany the seller. "100,000 Whys" grew up with me.

The 100,000 Whys is a book about the science of life, and it will make me understand many truths, as long as every time I open the 100,000 Whys, I will have a curiosity in my heart.

Whenever I open the book "100,000 Whys" and see that there are many profound questions on it, I become curious. "100,000 Whys" is a series of popular science knowledge books, with countless contents. From astronomy and geography to trivial matters in life, each article tells us a small scientific truth.

It not only helps me broaden my horizons and increase my knowledge, but also increases my interest in learning, which is really a good helper for me. Before, I didn't know about the Nine Planets and the Milky Way at all. "100,000 Whys" introduces us to the formation of celestial bodies.

I learned that Venus, Mercury, Saturn, Jupiter, Mars, Earth, Uranus, Neptune, and Pluto are the nine planets in the solar system. The Milky Way, on the other hand, is made up of many nebulae like the solar system. The Earth we humans live on is just a "little star" in the universe.

100,000 Whys often introduces us to interesting natural phenomena, such as how the "four seasons" of the year are formed. What color is under the seabed? Why is sea water blue?

Wait a minute. I discovered a lot of scientific truths and solved some mysteries in my heart. One of the articles I was most interested in in this book was "Why do you want to hit three inches and seven inches when you hit snakes?"

The book says that the snake is beaten three inches because three inches is the easiest place to break the snake's vertebrae, so once it is broken, the organs behind it are also destroyed. Hit the seven inches because the seven inches are the part of the snake's heart, and if the heart is broken, of course the snake will die. During the holidays, I often traveled to the mountains with my parents, and I heard that there are many snakes in the mountains, and if I run into them, I know how to deal with them.

100,000 Whys also answers some questions in daily life, such as: Why are apples both laxative and antidiarrheal? The reason is that apples are rich in organic acids and a particularly high amount of fruit and vegetable gum; Why brush your teeth at night?

Because the bacteria in the mouth can cause food crumbs to spoil and ferment. In short, "100,000 Whys" is a good book, it made me realize that the world is so colorful, and the knowledge is so intellectually interesting; It taught me that science is power and knowledge is wealth. I like "100,000 Whys", when you open the book, the interesting knowledge stories make you confused; I love "100,000 Whys", which is a fun, informative and inspiring book series, which fascinates me deeply.

In the wilderness of nature, how many paths lead to the peak of knowledge of nature, I will follow this path, wander in the ocean of knowledge, and be a useful person.

"100,000 Whys".

I recently read the book "100,000 Whys", it tells me the story of the earth and the universe, and it can take me to many interesting places. For example, is the Milky Way a river? What is the universe, etc., these sparked my curiosity.

There are many parts in this book: interesting facts about the earth, mysteries of the universe, the vast earth, the vast ocean, the wonderful sky, etc., all of which have enriched my knowledge. For example:

How old is the Earth? Are there mountains under the sea? Is the snow clean?

There is a little observer behind each content, the world is really wonderful and easy to test you, making our extracurricular knowledge more colorful!

In the end, I learned that we need to protect every plant and tree around us, save water, and protect the resources around us. I enjoyed reading this book very much.

Reading "100,000 Whys" has a feeling.

5,000**, 7,000 how, 100,000 why. "I'm sure everyone has seen "100,000 Whys", it may be about plants, animals, and ...... about the universeBut have you ever thought about these questions: Can water blow up houses, why can't water burn?

When I opened the book, I felt a magical force that brought me in. When I didn't open the book, I thought that science was far away from us, maybe in the science base or in the universe and nature. And when I opened this book, I discovered the science that surrounds me.

Is there opaque water and iron? When did humans start making fire? Is it warm with three shirts, or warm up with one shirt that is three times thicker?

Why does a beer glass squeak when it opens and foam bubbles? What is soup? Why does milk turn sour......These problems happen all around us.

In daily life, there will be a life stove every day, someone will light a kerosene stove, someone will cook potatoes, many people can do these things very skillfully, but few people can answer the above questions.

For example, do you warm up with three shirts or one shirt that is three times thicker?

The answer is to warm up with three shirts.

The key to keeping warm is how much air is between the shirtsAir is a bad conductor of heat, so the more air between the shirts, the thicker the "air clothes" that make our bodies feel warm.

Three shirts are like three "air clothes", and a shirt three times as thick is just one "air clothes". ”

These are these questions that no one thinks about in life and only does. And when you open this book, you will think that these ordinary little things contain so many scientific principles.

Open the book. The author introduced us to various scientific principles, but the author did not use such blunt science and techniques, but humorously introduced to us the blunt scientific principles, and the blunt scientific principles in his pen were like alive and full of life.

I learned a lot during such a short trip, for example, I learned to introduce what I wanted to introduce in various ways, such as listing numbers, giving examples, analogies, ......I hope I can write such an interesting book in the future.

100,000 Why 400 Words for Fourth Grade After Reading:

During the summer vacation, my mother bought me a copy of "100,000 Whys", which is really a very good book! There was a lot of knowledge in it, and I felt like I had entered an ocean of knowledge. This book "What to Ask 100,000" is the work of Liang Chang, a former Soviet writer Mi Yilin Wuheng.

The book is divided into six parts, which can also be said to be six "stations", as well as appendices. It contains knowledge about water, fire, food, metals, mirrors, animals, plants, and more.

I never imagined that in just one house, the author would discover so many observable things and ask so many questions. He must have looked at the object from all angles and kept notes. I'm still far from that and I really admire Miylin!

This "100,000 Whys" is very different from the popular science books I used to read.

This book is like "knowledge" snowballing, and the further you read it, the bigger the snowball of knowledge becomes. At the end of the reading, everything was condensed together, which made me understand that everything is closely connected, such as animals and plants, water and fire, etc. Unlike other popular science books, they are all described one by one according to specific things.

So, I like this book "100,000 Whys" even more.

By reading this book, I understood that science is all around us. In the future, I will carefully observe and think about it. This is the biggest takeaway from reading this book.
