Becoming a stepmother of three children gives me space

Xiaobao was very enthusiastic about scientific research and continued to make the mud boat. The two little guys stared with wide eyes and watched the mud boat sink to the bottom of the water again.

Obviously,

He only has spirit, but no strength.

"Or not."

Xiaobao scratched his head, wiped his nose, rubbed it on his clothes, continued to make the mud boat, and continued to sink the boat.

Xiao Yunxi decided to give them a vivid physics lesson, otherwise the last clean piece of clothing belonging to Dabao on Xiaobao would be destroyed!

"Do you know why a boat floats?"

Niuniu is in charge of being cute, shaking her head like a rattle, Xiaobao is scratching his head, and Goudan is a genius of logic:

"Because a boat is a boat, it floats on the water."

Seems to be fine!

Xiao Yunxi smiled and said:

"Let me first tell you the story of Cao Chong weighing an elephant."

Dabao was attracted to come over. The stories his mother told were very interesting. The stories about Zhao Rou and Mai Li, and the friendship between Guan and Bao all contained profound life philosophy.

"There was a Prime Minister Cao who took his friends to see an elephant. The elephant was so tall and huge that its legs alone were as thick as the pillars of a large hall."

Xiaobao exclaimed:

“Are elephants really that big?”

Xiao Yunxi nodded:

"It really is. People can't even reach the elephant's belly. It's so huge."

"So...is elephant delicious?"

Dabao:!!!

Xiao Yunxi: I want to see the punishment!

"Elephants are not tasty. Besides, they live in the hot south. You can't eat them."

Xiaobao had a very regretful expression. This kid's mind was full of eating.

"When Prime Minister Cao saw how big the elephant was, he curiously asked how heavy it was. No one could come up with a solution, but Prime Minister Cao's son Cao Chong came up with one. Can you guess what it was?"

Gousheng scratched his head:

"Build a really big scale to weigh it."

"But the elephant is alive?"

Xiaobao raised his hand and said excitedly:

"Chop him into pieces!"

Xiao Yunxi felt that interacting with Xiaobao was a mistake.

"Cao Chong led everyone to the riverside, pointed to a large boat, and said that if they could pull the elephant onto the boat, they could measure its weight."

The aunts were also listening to Xiao Yunxi's story, and when they heard this, they raised questions.

"Can the boat be weighed?"

"That's right, how can a boat weigh an elephant?"

Everyone looked confused, only Dabao seemed to be thinking about something. Xiao Yunxi asked him:

"Have you thought of a solution?"

Dabao pondered for a moment:

"Pull the elephant onto the boat and stabilize the boat at the mark where the boat's side is level with the water. Then bring the elephant back to shore and load people onto the boat until the waterline is level with the mark. Then weigh the people and add up the weight to get the weight of the elephant."

Xiao Yunxi gave Dabao a thumbs up.

"Excellent! Cao Chong's method is the same as yours, but do you know the principle behind it?"

Dabao shook his head.

The fact that he could come up with this method was a summary of common sense in life, but he didn't know the specific principles.

Xiao Yunxi told him:

"It's buoyancy... The buoyant force on an object in water is equal to the weight of the water displaced, so the total weight of a person is the same as that of an elephant."

"What is buoyancy?"

"Kites can fly, boats can swim, and Kongming lanterns can soar into the sky. This is all because of buoyancy. As long as the buoyancy is strong enough, a piece of iron can swim in the water, and a person can fly into the sky."

The two silly brothers Xiaobao and Goudan opened their eyes wide:

"Really? Can people go to heaven?"

"Of course, as long as the buoyancy is strong enough, you can do it. Mom will show you how."

Xiao Yunxi picked up two pieces of mud of similar size, rolled one into a solid ball, and kneaded the other into a small rectangular mud boat, making it as big as possible.

The mud ball sank to the bottom of the water, and the mud boat floated on the surface.

"Ah! The mud is really floating!"

"Mom is so awesome!"

"Auntie is amazing."

"It's very cold."

The little ones showed their support, and Xiao Yunxi was elated:

"Do you know why a small mud boat can float but a mud ball can't?"

The little ones shook their heads. Xiao Yunxi looked at Dabao, who thought for a moment:

"Is it buoyancy?"

"Yes, it's buoyancy,"

"Why do the same pieces of mud have different buoyancy?"

Xiao Yunxi picked up another piece of mud of almost the same size and put it in the mud boat. The mud boat still did not sink. She added more mud balls, but it still did not sink.

The little ones cheered excitedly, while Dabao seemed to be lost in thought.

"Buoyancy is related to volume, or shape. Of two identical mud balls, the larger one has greater buoyancy, which is why it can float on water. Do you want to fly into the sky?"

"miss you!"

"If you want to, you have to study math well, because math is the foundation of science. To learn math first, you need to learn addition, subtraction, multiplication and division. Have you memorized the multiplication formulas I taught you?"

"..."

Xiaobao was acting cute, he obviously didn't remember, but Niuniu raised her hand:

"Mom, Niuniu remembers."

"Then Niuniu recites it to mother."

Niu Niu is young, but she has a very good memory. Although she needs Xiao Yunxi's reminders for some things, it is surprising that she can remember so much.

As for Xiaobao, his face was red, and he felt a little embarrassed to be outdone by his sister.

Xiao Yunxi rewarded Niuniu with a piece of candy and patted Xiaobao's head.

"Xiaobao, keep working hard. If you can memorize the multiplication table, I'll make you a new dish."

When Xiaobao heard that there was food, he immediately became excited.

"I will work hard!"

Interest is the best teacher.

Xiaobao and Gousheng thought it was amazing that the mud boat could float and hold two mud balls without sinking. They even yearned for Xiao Yunxi's idea of ​​a person flying into the sky.

So I studied very seriously, and soon I memorized all 10 Arabic numerals, and even roughly understood what addition and subtraction meant.

Time passed quickly. The children learned addition and subtraction of single-digit numbers, and the moisture in the tofu was almost compressed. Xiao Yunxi's teaching class was temporarily offline.

Move the stone off the wooden box, open the wooden board, lift the gauze, and the white and tender tofu will appear before your eyes.

"so white."

"so beautiful."

“Just looking at it makes me want to eat it.”

"Yunxi, how do you eat tofu?"

Everyone was talking about it, the taste of soy milk was still lingering in their mouths. I guess the tofu would taste good too, right?

Seeing that it was lunchtime, Xiao Yunxi prepared a tofu feast.

Cut the tofu into cubes, fry it a little, sprinkle some salt on it, and you have a delicious fried tofu.

Coat it with egg liquid and fry it in oil, then add some sauce and simmer it for a while, and you will have a simple version of pot-fried tofu.

Stir-fry the pork belly until the meat is cooked, add the tofu and stew it, it is braised tofu.

Fry the Sichuan peppercorns until dry and fragrant, then remove and crush them. Add the minced meat and chili sauce and stir-fry until fragrant. Add water, add the tofu and cook until thickened. This is Mapo Tofu without the soul of the bean paste.

Cabbage, tofu and vermicelli noodles, meat and tofu soup, stuffed tofu, and the main dish is tofu rolls.

Make a dish of scrambled eggs with tomatoes, which the kids love, and then add a meat dish and lunch is ready.

The village chief and Uncle Tang came back just in time for dinner.

The dishes were divided into two groups, one table for men and one table for women and children. Everyone ate the tofu feast and praised it highly. They never expected that cheap soybeans that no one eats could be used to make such delicious tofu.

The maid brought Mrs. Zhou's food, and the portion was obviously larger than yesterday. It was because he owed her a favor.

Xiao Yunxi delivered food to Hu Zi and his mother, and also took the opportunity to check on Hu Zi's mother's condition. She had internal injuries, so it would be best if she could undergo surgery as soon as possible to avoid any accidents.

I agreed with Dr. Lu to have surgery today, but I haven't seen him since morning. I don't know if he can successfully get all the necessary items for the surgery.
