Little Rascal felt that the jar was not filled with anything good. In fact, it was the most disgusting thing in the world! Tong Tong did not understand why his sister and father were so interested in the jar. He even wanted to stop his sister from touching the terrible thing.
However, Murphy thought that he was going to cause trouble, so she held him in her arms and stopped him from moving. The little boy struggled and tried to escape from his mother's arms.
No! Let me go! I want to save my sister!
"Wow!" Suddenly, Tong Tong heard his sister's excited cheers. He stopped moving in confusion and raised his head to look over.
Of course, Tong Tong did not notice the details. He only saw his sister and father looking at the big jar carefully.
If this was a cartoon, there should be many question marks floating above the little guy's head at this moment: What happened? Why is my sister so excited?
Little Momo didn't notice that the egg in the glass bottle had already floated up from the muddy water. Although it was only floating in the water, this change was enough to make Xi Xi cry out in surprise.
"Papa, the egg is floating!" Xi Xi turned her head and excitedly reported to her father.
"It hasn't completely floated yet. Try adding more salt." Yang Yi encouraged Xi Xi and finished the experiment.
Of course, there was no need to elaborate on the following experiment. It was just adding more salt to make the egg float.
What Xixi was more curious about was what kind of magic could make the eggs float out of the water.
After growing up, Xi Xi, who had not asked about it for a long time, asked her father with great interest today, "Papa, why is it like this?"
This scientific principle was not difficult to explain. The difficult part was how to explain it to Xi Xi. Xi Xi did not know what buoyancy was, what specific weight or density was.
Therefore, Yang Yi pondered for a while and said, "Xi Xi, which do you think is heavier, the egg or the water?"
Xi Xi tilted her head and thought for a while. In the end, she chose water.
"Because it's very heavy. It's hard for me to lift it up!" Xi Xi pointed at the glass bottle of water and said seriously, "But the eggs are easy to get!"
Yang Yi understood his loophole. He took two identical cups and eggs and began to demonstrate.
"Look, I put an egg in one of the cups and water in the other, but the volume of the water I added is about the size of an egg." Yang Yi smiled and handed the two cups to Xi Xi. "Now look, which one is heavier?"
However, the difference in weight was negligible. Xi Xi weighed it in her hand, but she still couldn't figure it out.
Yang Yi had no choice but to ask for a small electronic scale used in the kitchen to weigh vegetables. After comparing the weight data of the two, Xi Xi finally had an answer.
"Now, which do you think is heavier, the water or the egg?" Yang Yi asked with a smile.
"The egg is heavier!" Xi Xi's reaction was very fast. She kept up with her father's thinking speed.
"In addition, do you think iron of the same size is heavier? Or wood of the same size is heavier? "Yang Yi asked.
Xi Xi didn't need to do an experiment to know how to answer this question. She replied crisply, "Iron is heavier!"
"That's right. Under the premise of the same size, iron is heavier than wood, and eggs are heavier than water. We call the reason why it's heavier is that it's denser!" Yang Yi still used iron and wood as an analogy. "It means that its small body is stuffed with more and heavier things."
Xixi nodded her head as if she understood something.
It was indeed difficult to explain, but Yang Yi felt that if he explained more, Xi Xi would also understand more subtly. In the future, she would also be able to understand some of the scientific knowledge he was talking about.
"That's good. The reason why this dense egg can sink to the bottom of the water is that it's heavier than water. Don't you think so?" Yang Yi said with a smile.
Xi Xi could understand this. The little girl nodded her little head with a serious face.
"Then we add salt to the water. The salt will be integrated into the water. That way, when we drink the salt water, we will feel the saltiness." Yang Yi made a relatively new analogy. "It's like we're carrying a schoolbag with things in it. Now, we have to unzip it and continue to stuff things in it. Won't it become heavier?"
"Yes!" Xi Xi continued to nod.
"Then why is that?" Yang Yi smiled and asked Xi Xi a small question.
"Because, because …" Xi Xi still didn't understand. At this moment, facing her father's question, she was confused again.
Murphy listened to the side with great interest. Seeing Xi Xi say that she understood for a while and then open her mouth but couldn't answer, she couldn't help but say, "Didn't your father say just now? It's because it's density has increased, so it's also heavier! "
Yang Yi smiled and said, "It doesn't matter. We now understand that after adding salt, the salt water will be heavier than water!"
"I know, I know, because it has salt!" Xi Xi actively rushed to say at this moment.
"That's right. If you continue to add salt, it will also become heavier!" Yang Yi didn't intend to talk about the more profound concept of solubility for the time being. He only said, "Because the salt water has become heavier, when it is heavier than an egg, then the lighter egg will float, right?"
Xixi's eyebrows danced as she listened. She didn't know if she really understood, but she kept nodding her head.
"Let's see if we can apply today's discovery to a wider range of examples!" Yang Yi smiled and said, "For example, do you think that swimming in the sea, like swimming in the sea in the summer, is easier to float in the water than swimming in our freshwater swimming pool?"
How could Xi Xi remember these two feelings? However, although she couldn't compare which of the two swimming was easier to float, Xi Xi still understood what her father wanted to say.
The little girl giggled and said happily, "I know, I know, because the sea is also salty! There's salt! "
"That's right!" Yang Yi praised and gave a thumbs up.
"Papa, papa, let's continue to play with other experiments! It's so interesting! "Xi Xi waited for her father to finish talking about these principles and couldn't wait to shout again.
It was such a big book, so there must be a lot of interesting content!
Xi Xi laughed in high spirits, while Tong Tong looked at her from the side. He couldn't understand these principles, but the little fellow felt that his sister was smiling so happily, so there must be something very interesting. His little eyes were filled with envy and anticipation.
He really wanted to play with his sister!
…
The shooting of "Yu Zui" had been going on for more than a month. Recently, the crew went to the south to shoot some local scenes in Yang Cheng City. As an important supporting role, Guo Ziyi also went there.
However, the weather suddenly turned cold, and the news reported that the cold air had not been seen in ten years. Tan Huizhen began to worry about whether Guo Ziyi, who was further south in Yang Cheng City, would be frozen to death.
There was a popular saying on the Internet: "I'm a wolf from the north, but I froze into a husky in the south."
Although it was a joke, there was some truth to it!
The cold in winter in Guangdong Province was humid and cold. Although the temperature looked high, the high humidity made the cold feel as if the cold air was going to penetrate into the bones, making people feel uncomfortable!
Therefore, when Tan Huizhen called Guo Ziyi, she suddenly asked where Guo Ziyi's agent was now.
"Why are you asking about Ding Xiang?" Guo Ziyi became alert. "She's in Jiang City! She still has schoolwork, so she can't run around with me before she graduates. "
At this moment, Ding Xiang, who was sitting next to Guo Ziyi, nervously straightened her back and looked at Guo Ziyi.
