But Mo Fei thought he was going to mess up, and he held him in his arms, not letting him move, the little guy was “hurried” and wanted to escape the bondage of his mother.
No! Let me go, I am going to save my sister!
“Wow!” Suddenly, the little servant came over with his sister’s excited cheers. He suspiciously stopped the action, raised his small head and looked at the past.
Of course, the small postal exchange is more attached to the model. He just saw that his sister and father are looking around the big bottle.
If it’s an animated cartoon, there should be a lot of question marks on the little guy’s head at the moment: What happened? So excited for my sister?
At this time, the eggs in the glass bottles have already floated in some white water. Although it is only suspended in the water, this change is enough to make Xixi surprised.
“Papa, the eggs are floating!” Xixi turned his head and excitedly reported to Dad.
“I haven’t fully floated yet, try adding some salt to it.” Yang Yi encouraged Xixi to finish the experiment.
Of course, there is no need to repeat the following experiments. It is nothing more than adding more salt to make the eggs surface.
Xixi is more curious, is there any magic, let the eggs float out of the water?
This is not. After growing up, Xixi, who hasn’t asked why for a long time, asked Dad today with great interest: “Papa, why is this?”
This scientific principle is not difficult to explain. The hard part is how to explain it to Xixi to listen and understand. Xixi now doesn’t understand what buoyancy is, what is gravity or density.
Therefore, Yang Yi pondered a bit, first said: “Xixi, do you think it is heavy, or is the egg heavier?”
Xixi thought about it with his little head, but he chose water.
“Because it’s heavy, I can take it hard!” Xixi pointed to the glass bottle filled with water and said seriously, “But the eggs are good!”
Yang Yi understood his own loopholes and he took two identical cups and eggs and started to demonstrate.
“Look, I am putting eggs in a cup, adding water to a cup, but the water I added is about the size of an egg.” Yang Yi smiled and handed two cups to Xixi. “Look now, Which one is heavier?”
However, this weight difference is still very small, and Xixi has measured it a bit, but it doesn’t matter.
Yang Yi had to go to the kitchen to weigh the weight of the small electronic scales, compare the weight data of the two, Xixi finally got the answer.
“Now do you think that water is heavier or is the egg heavier?” Yang Yi asked with a smile.
“Eggs are heavy!” Xixi reacted quickly, keeping up with Dad’s thinking speed.
“In addition, do you think the same size of iron is heavier? Or is the same size of wood heavier?” Yang Yi said.
Xixi didn’t have to experiment and knew how to answer this question. She only listened to her crisp response: “The iron is heavier!”
“That’s right. Under the same size, the iron is heavier than the wood, and the egg is heavier than the water. The reason we call it heavy is called its density!” Yang Yi is still made of iron and wood. The metaphor, “meaning that it is stuffed with more and heavier things in this small body.”
Xixi seemed to understand and nodded.
It’s really hard to explain, but Yang Yi feels that if he says too much, Xixi will know more about it in the subtleties, and he will be able to understand some of his scientific knowledge later.
“Well, this dense egg can sink to the bottom because it is heavier than water. You say yes?” Yang Yi said with a smile.
This Xixi can understand that the little girl has a little bit of a serious face.
“Then we add salt to the water, the salt will be integrated into the water, so when we drink salt water, we will feel the salty taste.” Yang Yi made a relatively fresh metaphor, “It is like, we are back With a schoolbag loaded with things, now we have to open the zipper and continue to stuff things inside, so will it become heavier?”
“Yes!” Xixi continued to nod.
“So why is this?” Yang Yi smiled and asked Xixi a small question.
“Because, because…” Xixi really couldn’t understand, and now, in the face of Dad’s problem, she was confused.
Mo Fei listened with a sigh of relief. When she saw Xixi saying that she understood it, she couldn’t answer her mouth with a mouth open. She couldn’t help but say: “Don’t your father just say it? Because its density has increased, So it has become heavier!”
Yang Yi smiled and said: “It doesn’t matter, we understand now that after adding salt, the salt water will be heavier than water!”
“I know, I know, because it has salt!” Xixi, now, actively rushed to say.
“Yes, if you continue to add salt, it will become heavier!” Yang Yi is not going to talk about the concept of more profound solubility for the time being, just saying, “Because salt water becomes heavier, when it is heavier than eggs, Will the light egg float up?”
Xixi listened to the dance, and I don’t know if I really understood it. Anyway, it was continuous.
“We can see today’s findings on a wider range of examples!” Yang Yi laughed. “For example, do you think that swimming in the sea? For example, in summer, we go to the seaside in Binhai District. Is it easier to swim in the freshwater swimming pool of our home, and it is easier to float in the water?”
Xixi Where do you remember these two feelings? However, although she couldn’t compare which of the two swimmings was easier to float, Xixi understood what Dad had to say.
I saw little girl, smiled and said happily: “I know, I know, because the sea is salty! There is salt!”
“Yes!” Yang Yi gave a thumbs up with praise.
“Papa, Papa, let’s play another experiment! It’s so interesting!” Xixi and other daddy finished these sensations and couldn’t wait to scream.
With such a big book, there must be a lot of interesting content!
Xixi smiled and fluttered, the little glaze 哐郯 哐郯 乜 乜 乜 乜 乜 乜 拧 拧 庑┑ 庑┑ 庑┑ 庑┑ 恚 恚 恚 恚 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是 是The eyes are full of envy and expectation.
I really want to play with my sister!
……
The shooting of «Yu Zui» has been going on for more than a month. Recently, the production team went south and went to Guangzhou to shoot some local shots. Guo Ziyi, as an important supporting role, followed the past.
However, the weather suddenly turned cold, and the news report said that it was a cold air that had not been seen for ten years, so that Tan Huizhen began to worry about whether the Guo Ziyi in Guangzhou, which is still south, would be frozen.
Not a popular saying on the Internet now: I am a wolf from the north, but frozen into a husky in the south?
Although this is a joke, there is still some truth!
Guandong Winter is cold and cold, although the temperature looks very high, but the high humidity of the air will make this cold as a bone, and the yin measurement seems to be as uncomfortable as drilling cold into the bone!
So, when Tan Huizhen called Guo Ziyi, he suddenly asked where the agent of Guo Ziyi is now?
“What do you ask Ding Xiang?” Guo Ziyi was alert. “She is in Jiangcheng! She still has classes, and it is impossible to follow me around before graduation.”
At this moment, Ding Xiang, who is sitting next to Guo Ziyi, nervously straightened and looked at Guo Ziyi in a dangerous position.
