Chapter 81 Natural Science

After ten days of classroom teaching, the students in the school received their first big lesson in life.

The so-called big class is a class where more than a hundred students attend together.

There is no way, only Song Yang can teach nature class.

So he can only take this class in the form of a large class.

Of course, with more than 300 students in total, it would be too taxing to gather them all together.

In the end, we were divided into two classes, one in the morning and one in the afternoon.

In the small square in front of the teacher, a podium over one meter high was set up.

More than a hundred students gathered in the audience.

Not far away was a construction site where a dock was being built. The people who were under construction stopped what they were doing and looked at Song Yang with curiosity.

Everyone doesn't know what nature is.

And I have never heard of teaching more than a hundred students at a time.

In addition to the students, there are also two teaching assistants in this big class, Wei Nan and Gongsun Qi.

Wei Nan's student is in the audience now. On the one hand, he is helping Song Yang maintain order, but on the other hand, he is also curious about what nature is.

"Classmates, our class is called Nature."

"So what is nature? What do we learn in nature class?"

"Nature is the principle of everything in the world."

"The purpose of studying nature is to let everyone understand all things in the world and understand the essence of nature."

"Nature is all-encompassing, including astronomy, earth, biology, physics, chemistry and many other contents."

"Studying nature is an important means for us to understand nature, understand nature, and use nature."

"You may not understand what I say yet, but it doesn't matter, through our continuous learning."

"You will understand what nature is and what use nature is to us!"

Song Yang delivered a speech to open the class, but the students' reaction was not strong.

Most of them looked confused and had no idea what Song Yang was talking about.

Even people like Wei Nan and Gongsun Qi who could read didn't know what Song Yang was talking about.

Song Yang looked at the confused children in the audience and said with a smile:

"Do you know why it rains?"

Song Yang's question immediately aroused the children's interest.

"It's the Dragon King sneezing!"

"No! It was Master Rain who cast the spell!"

"I heard my father say that rain is the tears of water girls."



A small question, got a variety of strange answers.

When the students' voices became quieter, Song Yang pressed his hands to silence everyone.

"What you said is totally wrong!"

"Rain is actually a natural phenomenon."

"When the cloud layer reaches a certain thickness, the water droplets that make up the clouds will naturally fall and form rain."

"Rainwater is water vapor on the ground that forms when exposed to sunlight. The water vapor evaporates and rises into the air. When it encounters cold air in the air, the water vapor condenses into water droplets."

Song Yang's words made the underground students confused again.

Not only the students, but also Wei Nan and Gongsun Qi were in a state of confusion.

What are these things, clouds, water bottom, water vapor condensation?

Never heard of it!

"Are you confused? Isn't it amazing?"

"But that's part of the natural sciences."

"After our study, you will gradually understand the truth."

Song Yang calmed everyone down by asking a small question, and he was quite satisfied.

Suddenly, a voice broke the silence.

"My lord, how do you know the reason for the rain?"

"Seeing is believing, and hearing is believing. Have you ever seen it with your own eyes?"

Under the stage, a young man suddenly asked a question.

Song Yang took a look and found out that this kid was the naughty guy in their class, his name was Chu Zian.

His father, Chu Xiang, was an official in Jiangzhou Xuezheng Yamen.

But he died during the natural disaster.

Now Chu Zian lives with his mother.

Chu Zian is also a child of a scholarly family and has learned to read and write since he was a child.

I am eight years old this year and have already finished studying three hundred thousand.

Although his temper is a bit naughty, his grades are the best in the class.

Moreover, Song Yang was very familiar with him. This boy was the first person Song Yang saw after he came to this world.

He also gave Song Yang a bowl of porridge.

Song Yang hooked his hand and asked Chu Zian to come to the podium.

"Zian, you asked a very good question."

"I can know the reason why it rains because I understand the reason."

"But this principle is still relatively profound for you."

"As long as you learn slowly, you will understand."

"And when you all have mastered the truth, I will lead you to do experiments and prove the correctness of the truth through experiments."

Song Yang touched Chu Zian's head and said.

Chu Zian seemed to understand, but was obviously not satisfied with Song Yang's statement.

Song Yang also wanted to prove his statement now, but the tools were limited.

At this moment, I suddenly felt that it was not very wise to talk about rain.

After all, there is no way to verify...

"Students, do you know why there is a rainbow after it rains?"

Song Yang had an idea and suddenly thought of rainbows from rain.

"Is it the magical Rainbow Bridge?"

"Definitely not! The prince will definitely say that this is natural!"

This time the children no longer expressed their original opinions.

Chu Zian didn't say anything and just looked at Song Yang.

Song Yang smiled and said: "Rainbow is a natural phenomenon and it belongs to the optics part of natural science."

"When sunlight strikes water droplets in mid-air, the light is refracted and reflected, forming an arched colorful spectrum in the sky. From the outer circle to the inner circle, there are seven colors: red, orange, yellow, green, blue, indigo, and purple.

.”

Song Yang threw out another theory.

The students were still confused, and Wei Nan and Gongsun Qi still didn't understand.

Chu Zian frowned and looked at Song Yang, feeling that he was a bad person who deceived children.

Water droplets in the air?

Where are the water drops?

This time Song Yang was confident, he patted Chu Zian and said with a smile: "This time I can prove it to you through experiments."

"Ah? How to prove it?" Chu Zian asked curiously.

Song Yang looked at the sky. At three o'clock in the morning, the sun was already high.

It's a good time to do experiments now.

So Song Yang walked back to the desk and picked up a glass of water.

"Look carefully, don't blink."

Song Yang smiled and took a big drink of water.

Then……

"puff!"

I saw Song Yang spraying into the sky.

Suddenly water mist splashed.

"this!"

"It's a rainbow!"

"I saw it! It's a rainbow!"

"My lord, you turned out to be a rainbow!"

Chu Zian was so close that he could see Song Yang's "spouting" rainbow at a glance.

The boy was dancing excitedly.

"The water mist I sprayed just now turned into tiny water droplets in the air. The sunlight shone on the water droplets, reflecting the color of the sun."

"How about it? This is a rainbow. This is natural science. Isn't it interesting?"

Song Yang held the water glass and looked at Chu Zian and the children in the audience.

Wei Nan and Gongsun Qi on the side looked stunned.

It turns out that nature is just such a little trick!

They seemed to have seen it before when watching street performers...

But the children didn't think so. They all thought the prince had turned into a rainbow.

The colorful colors did appear.

There was constant discussion for a while.

The children's curiosity about natural science was immediately raised.

Of course, Song Yang's small experiment also caused a certain waste of fresh water resources in the new city for some time to come.

So many parents got into fights because their unlucky children sprayed dry clothes hanging in the yard...
