"The truth is born after a hundred question marks" PPT courseware 7

Apple falls to the ground (Newton's discovery)

An accidental event can often trigger a spark of thought in a scientist.

It was a warm evening in the late summer of 1666. In Ullsthorpe, Lincoln, England, a young man with a book under his arm walked into the garden of his mother's house, sat under a tree, and began to bury his head. Read his book. As he turned the pages, something shook in the branches above him. One of the most famous apples in history fell and hit 23-year-old Newton on the head.

It happened that that day, Newton was thinking hard about a question:

What force keeps the Moon in its orbit around the Earth and the planets in their orbits around the Sun?

Why did the apple that hit him in the head fall to the ground?

Students read the text aloud:

1. Mark the serial number of each natural paragraph

2.Which point of view is the text centered around?

3.How many parts is the text divided into?

4. How many things are written in the text?

The text is divided into three parts:

Part One (1): Get straight to the point and put forward your point of view. It is clearly stated that "truth is born after a hundred question marks" itself is "truth".

The second part (2-6): Use examples to prove the point. This is the main part of the article. First, it briefly points out the discovery of scientific truths. Those theorems, laws, and doctrines were all solved by the discoverers and creators. "After hundreds of question marks" was obtained. Then, three representative examples in the history of scientific development were derived. Finally, the three typical examples were summarized.

The third part (7, 8) summarizes the full text and reiterates the point of view. It points out that science is neither mysterious nor far away. The key lies in "knowing the subtleties and seeing the subtle things", constantly exploring, being good at independent thinking, and having a perseverance spirit.

Read the last two paragraphs of the text freely and talk about your own feelings?

Dudupinpin

In the history of science, there are many such examples, which show that science is not mysterious and the truth is not far away. As long as you know the subtleties, are good at asking questions and keep exploring, then you will be able to discover the truth after you answer a few question marks.

Of course, the ability to see subtle things, be good at asking questions, and constantly explore does not arise out of thin air. As the mathematician Hua Luogeng said, scientific inspiration cannot come by waiting. If there are any accidental opportunities for discoveries in the field of science, then this kind of "accidental opportunity" can only be given to those who are prepared, to those who are good at independent thinking, and to those who have the spirit of perseverance. people.

What did you gain from studying this text?

1 Understand the general law of scientific discovery: truth is born after a hundred question marks.

2 Understand the idea of ​​​​the article: put forward your own point of view at the beginning, then use three specific examples to illustrate that this point of view is correct, and finally elaborate on the starting point of view.

3. The "accidental opportunity" of scientific discovery can only be given to those who are prepared, and will not be given to any lazy person. I hope that students can also be "people who are scientifically prepared."

Central idea:

The text mainly uses facts to argue that as long as you know the subtleties, are good at asking questions and continue to explore, and persevere in pursuing the roots, you can discover the truth in real life.

write like an angel:

Please think about how to write a paragraph that imitates the text and uses specific facts to illustrate a point. For example, "Where there is a will, there is a way", "Hard work pays off", "Modility makes people progress, pride makes people fall behind" and so on.
