Exploring Space is about space, which contains many rich resources. Some asteroids, which actually contain many resources. This also explains the distribution of the universe. The distance between some galaxies makes us feel ashamed. For example, a star that is very close to us is several light years away, which means that even if we can travel through the universe at the speed of light, it will take several years to get there. This means that if we want to explore other mysteries in the universe, we need very advanced technology so that we can enjoy the universe.
The mysterious sun is also very interesting. The scale seen in the previous picture, look at those planets, not necessarily much bigger than our earth, but it is only after reading this book that we know that Jupiter and Saturn are hundreds of times bigger than the earth! These make us feel inferior. And the planet named after water, fire, wood and earth once puzzled me. Is mercury full of water? Is Mars full of fire?
Now I know, these are just metaphors. Gold, water and Mars are made of rocks, while Jupiter and Saturn are made of gas. This is unthinkable. Gases can form planets. Does this mean that there may be oxygen on it? So can we live on it? These are just fantasies.
I am most interested in whispering. Those imaginary aliens are horrible and scary. But this book didn't scare me too much. But I really don't know how to describe this, so I just skipped it.
My first book, The Unsolved Mystery of the Universe, uniquely shows many scenes that once made us fantasize. It has a lot of astronomical knowledge. I once saw an Adventure in the Sun Age, which also talked about some knowledge about space. The farther away from the sun, the colder the weather. It is cold that can make a piece of steel smash when it falls from a height of one meter. But this book is a bit sad.
It can be said that this book has great feelings for me. And I can also produce great ideas from it, but although they are all illusory.
Look! What a great benefit a knowledge book has brought us. In this era of paying attention to science, if we don't learn more science, we will definitely be gradually forgotten by this era and will only fall behind little by little. Choose a good popular science reading, I believe it will bring you unexpected gains!
Reflections on reading popular science books II. I read a set of China Children's Encyclopedia, which is divided into four volumes. It can take you to eight places to play. These eight places are: China House, World Park, Global Village, Space Museum, Zoo, Botanical Garden, Science Palace and Sports Museum.
I learned many animal secrets in the zoo. Many animals can disguise themselves in different ways. Animals usually use protective colors, hidden colors and mimicry to disguise their bodies and paralyze their enemies to protect themselves. For example, zebras are disguised as protective colors; Lizards disguise themselves with hidden colors; Red mantis is disguised by mimicry; Poisonous arrow frog disguised as warning color ...
Most animals in nature live alone or live in groups and do not need to cooperate with another animal. But some animals can't live independently, and must rely on the help or sacrifice of other creatures to maintain their own survival. This is the habitat, health and parasitism of * * *. Such as the birth of termites and flagellates; Ascaris is a typical parasite; Clownfish and anemones are the habitat of * * * ...
In addition to natural plants, there are some high-tech plants in the botanical garden. And there are many kinds of cultivation methods! There are also soilless cultivation, such as greenhouse cultivation, and nutrient solution pools to make tomatoes grow into tomato trees, so that we can eat fresh tomatoes all year round. There are also anti-season plants and transgenic plants. What's even more amazing is space seeds. Scientists send seeds to spaceships and let them travel in space with astronauts. When the seeds returned to the earth, they mutated, and then better plant varieties were obtained through optimized cultivation. Isn't it amazing?
This China Children's Encyclopedia is worth reading!
As a primary school student, reading more popular science books at ordinary times is very helpful for our thinking growth. I read a popular science book "Encyclopedia of Students' Exploration" today.
The Encyclopedia of Students' Exploration is a very thick book, which contains three major contents: natural exploration, scientific research and historical review. We know that human beings live in nature, which is mysterious and colorful and contains many profound truths. The current scientific progress of mankind is only the tip of the iceberg to solve the mystery of nature, so human beings must constantly explore nature and understand the mystery from it in order to enhance their wisdom.
Secondly, the students' exploration encyclopedia also tells us to do scientific research, which also gives many examples of scientific experiment steps, and makes it clear that scientific experiment is the best way to verify the theory. As the saying goes, "practice is the only criterion for testing truth", and scientific experiments are also the only way to test scientific theories.
Then there is a historical review. The encyclopedia of students' exploration points out to readers that only by constantly reviewing history and drawing lessons from it can human beings move forward.
Generally speaking, we primary school students should spare more time to read useful extracurricular books to enhance our knowledge and promote our development.
Reflections on reading popular science books 4 I read the book "Why 100,000 are in Space" this summer, from which I learned a lot of scientific knowledge. For example, the largest celestial body in the solar system is a comet, commonly known as a comet, which consists of a coma head and a coma tail, of which the coma head consists of a nucleus and a coma. The diameter of the comet nucleus is about 10 km, and the huge air mass around it is huifa, with a diameter from tens of thousands to hundreds of thousands of kilometers. Wei Hui is even longer, reaching hundreds of millions of kilometers.
I also know why the sun shines and heats up. This is because the sun is a star and the largest celestial body in the solar system. This big gas ball has been releasing a lot of light and heat. It is because of the sun that the earth has warmth, light and life. The surface temperature of the sun is about 6000 degrees Celsius, and the central temperature is150,000 degrees Celsius. This is due to the intense atomic reaction inside the sun. The sun consists of more than 70 elements, the main component of which is hydrogen. The high temperature and pressure inside the sun are the interaction between emotional nuclei there, thus releasing a lot of light and heat.
I also know that Mars is one of the eight planets in the solar system, and scientists call it the twin brother of the earth. This is because Mars has many characteristics similar to that of the Earth.
Looking through a telescope, you will find that Mars is just a sphere. Its poles are white polar crowns, just like the snow-covered north and south poles on the earth. Mars, like the earth, revolves around the sun at a certain angle. In addition, a day on Mars is 39 minutes and 35 seconds longer than a day on Earth. The difference is that a year on Mars is 687 days, which is 1 of a year on Earth. Nine times. Like the earth, there is an atmosphere on Mars.
The universe is magical. When I grow up, I must become a scientist to study the mystery of Mars. Can humans live on Mars in the future? Please believe me, I will study hard!
Reflections on reading popular science books 5 I read "2 1 century children's encyclopedia" this week, mainly introducing many knowledge such as exploring the universe, aquatic world, film and television world, transportation and architecture, electronic world and so on.
Among them, my favorite part is the part of invention and exploration, from which I learned a lot of knowledge. For example, Bell in Britain discovered an interesting phenomenon when he was studying the visual language of deaf people. When the current is cut off, the spiral coil also clicks with the sending code, which inspired him. So he devoted himself to the research of telephone. After many experiments, he finally invented the telephone, so that people who are far away from Wan speak as if they were standing opposite.
Another, do you know who made the most primitive canoe through continuous efforts and opened the first page of human shipbuilding? Inspired by ancient natural phenomena, human beings have a certain understanding that water can generate buoyancy for objects in it. People used floating objects in the water to resist floods, and since then, mankind has begun a new chapter in conquering the ocean.
From these two stories, we can see that science is around us. As long as you are good at discovery, diligent in thinking, and constantly trying to make mistakes, you can make great achievements. In this way, we can make life more exciting!
After reading this popular science book, I was fascinated by the book Insects. It turns out that there are so many mysteries in the insect world. I know: how cicadas break their shells in the morning; Dung beetles belongs to me how to roll a dung ball; How ants eat aphid secretions. It is also clear that the moth's son is wrong. Bees catch caterpillars not as their own sons, but to arrange food for future generations.
The first time I read Insects, it somehow attracted me. This is a popular science book describing the birth, labor, hunting and death of insects. The text is plain, fresh and natural. Humorous narration makes people laugh ... humanized bugs appear, what a strange and interesting story!
Watching, these bugs gradually became clear. I thought: If we protect the environment and don't pollute it, will these bugs still exist? Now the environment is deteriorating, will it happen again in the future? I carefully thought about the relationship between them, and this reading, Insect Story opened a brand-new door for me.

The first time I read Insects, it somehow attracted me. This is a popular science book describing the birth, labor, hunting and death of insects. The text is plain, fresh and natural. Humorous narration makes people laugh ... humanized bugs appear, what a strange and interesting story! Fabres's Insect Story makes me feel like a dream. Those specific and detailed words make me feel the presence of magnifying glasses, humidity, stars and insect smells from time to time, as if I were there. These bugs gradually became clear. I thought: If we protect the environment and don't pollute it, will these bugs still exist? Now the environment is deteriorating, will it happen again in the future? I carefully thought about the relationship between them, and this reading, Insect Story opened a brand-new door for me.
Now let's follow Fables' footsteps and go to the insect world to find out. There are singing cicadas, vibrant crickets, flashing fireflies, United and enthusiastic caterpillars, capable bending bees and funny nut elephants ... you will be moved by their friendship, shocked by the perseverance of these little guys and cheered by their various stunts.
After reading this book, I have a deep feeling: in the small insect world, it is as colorful as we humans, full of excitement and killing; Full of warmth and cold; Full of unity and cooperation, but also full of killing each other.
"Insect Story" gave me a lot of inspiration: dung beetles told me to persevere; Dendrolimus punctatus told me to unite and cooperate with my classmates and make great achievements. Mantis told me never to give in; The nut elephant told me to be meticulous; Spider told me to face different problems in different ways; The wasp told me to protect myself; Scorpion told me to learn to confuse my opponent and win.
Fabres observes insects very carefully. It is said that once Fables found an ant nest, so he bent down to observe the villagers' curiosity about what he was doing and surrounded them. When the sun went down, the ants all returned to their nests. Only when Fabres came to his senses did he discover the villagers around him. This shows that Fabres's devotion to his work and his love for insects. It was this love that made him friends with insects and wrote about them.
In fact, nature is the best encyclopedia, which always brings us endless beauty. A small flower in the field, a big tree by the roadside, a white cloud in the sky … all have endless stories.
As long as you find it with a pair of discerning eyes, you will get unspeakable surprises and happiness.
Reflections on reading popular science books 7 Today, my mother borrowed a book from the library and caught my attention. The book is called: 100,000 Why.
I couldn't wait to grab it and read it with relish. My mother smiled and said, let me ask you a question. Don't look if you can't answer! All right! I said confidently, OK! Question, can plants sleep? Huh? You're kidding. How do plants sleep? I don't understand, the book in your hand can answer you! Mom smiled and said, I'll look through the catalogue right away, ha! I found it! Plants can sleep!
I looked at the popular science book in my hand with admiration: 100,000 Why.
This book is really my good helper! The contents are full of magic, such as eating sardines will lead to longevity, and the touch panel of vampire fish can stick to other creatures to absorb its food-blood. In the ocean, animals kill each other to survive. In this book, you can explore the mystery and get to the bottom of it, and it can even help you solve the most difficult problems. In this book, all kinds of mysteries of nature can be solved. I love this book because it helps me solve problems and solve all mysteries.
After reading this book, I became smarter; After reading this book, I became a doctor; After reading this book, I was praised by others, ah! This popular science book: a hundred thousand whys-it's my secret recipe!
