Is the fastest way to turn ice into water?

This one seems to be quite interesting, much more interesting than charades.

The children were all very happy, and they tilted their heads to think.

Luo Wenfei preemptively said: "I know, take the ice to the sun." ”

Li Han said: "This is a way. But even if the sun is so big, it will take a few minutes for the ice to turn into water. It's not the quickest way to do it. ”

"Well, I'll think about it again. ”

"I see. A chubby kid said, "Add another convex lens." The convex lens has a converging effect on the sunlight, and when it shines on the ice, it can make the ice melt faster. ”

Yes, you know that.

Li Han praised: "It's so smart, I know a lot." You can do this to speed up the melting of the ice, but unfortunately it's not the fastest. We want the fastest way to do it, think again. ”

"I see, put the ice cubes in the red-hot pot. ”

"No, it should be thrown into a hot furnace. The temperature inside was so high that the ice melted into water in an instant. ”

"I see, you can use lasers. ”

The children each have their own way.

Li Han smiled: "Everyone is right, but unfortunately it is not the fastest way." ”

None of that?

The children continue to think.

The teachers who were busy fishing for lobsters also noticed Li Han's problem, and they were also thinking.

It stands to reason that there is only one way to turn ice into water, and that is high temperatures.

The higher the temperature, the faster it melts.

The common hot conditions, the children seem to have said, but none of them are correct.

The teachers thought about it and found that the solutions they could think of seemed to be exactly what the children were talking about.

None of them are right, which is a bit puzzling.

At this time, the teachers couldn't help but be a little puzzled and curious.

All of them paid attention to Li Han and the children, and they wanted to know, what was Li Han's method?

The children couldn't say the fastest way, and Li Han was not surprised.

Because the fastest way is not a normal way, you have to think outside the box.

It doesn't make much sense to let the children continue to guess, and Li Han decided to announce the answer.

He picked up a dead branch and wrote the word "ice" on the ground, and then asked the children what the word was.

The children all know each other, and they all say the word "ice".

Li Han said again: "Very good, everyone knows each other. So, let's take a closer look at my next move. Look closely. ”

"Yes!" the children replied in unison.

Many teachers also came over curiously, and they also wanted to see what Li Han's next move was?

Li Han used a dead branch to "wash" the side of the "ice" and slowly erased it.

Then, pointing to the rest, ask the children, "What's the word now?"

The word was simpler, and the children replied in unison, "Water." ”

Li Han said with a smile: "Yes, it's the word 'water'." So, do you now know the answer to my question?"

Well?

Children are a little confused, and they need time to think about it.

But all the teachers were pleasantly surprised.

I see.

If you remove the side of the word "ice", won't it become "water"?

This is indeed the fastest way to do it.

However, this is a solution that they could not have imagined in any way.

Why?

Because their minds simply can't think in this direction.

Now, they know the answer.

This gave them a sense of enlightenment, as if they had been empowered, and felt that their minds had become more active in an instant.

This is why they were pleasantly surprised.

What excites them even more is that when the children figure it out, it seems that it will have a greater effect on the children's thinking ability.

Thinking outside the box, this is definitely thinking outside the box.

Breaking the conventional thinking is undoubtedly very important for children.

Deng Cui said happily: "Li Han, your question is really wonderful, it will be of great help to children to break their minds." How the hell did you come up with this riddle?"

The rest of the teachers are also sighing in their hearts, worthy of being the author of "Tortoise and Hand Race", "The Wolf is Coming", "Song of the Goose", and "Compassion for Nong", and even a riddle is so different.

Riddles, which of course are also riddles.

It's just that in previous lives, this kind of problem was generally called a "brain teaser".

Brain teasers cannot be answered by conventional ideas, and they must break the conventional thinking and find another way.

It is indeed very helpful for children to exercise their thinking outside the box.

And this world does not yet have the concept of "brain teasers", there are only various riddles that are solved with conventional thinking.

All kinds of brain teasers are naturally gone.

Li Han said with a smile: "My main reason for this question is to break those conventional riddles and exercise the children's unconventional thinking." ”

Deng Cui and the teachers nodded straightly, and Deng Cui said, "Indeed, indeed." This is indeed a very good exercise for children's unconventional thinking. ”

At this time, the children also figured out why it would be the fastest way to remove the word "冫" from the word "ice"?

After thinking about it, the children were excited.

This kind of riddle is interesting, interesting, and fun. It's much more fun than charades.

"Brother Li Han, you come out with another one, another one, we still have to guess, it's like this. The children said.

Li Han smiled: "Okay, then there will be another one, you all listen to it." In autumn and winter, why do geese fly south to spend the winter?"

"I know that. Because geese are migratory birds, it is too cold in the north in winter, so they have to go to the warmer south to spend the winter. ”

That's how the kids answered.

I have to say that children still know a lot about these common sense issues.

But obviously this will not be the answer Li Han wants.

Teachers are also thinking. With the experience of the first question, they already know that the answer will definitely not be what the children say.

That's conventional thinking, and you have to break the conventional thinking.

It's just that even if I know that I need to think outside the box, the answer is not easy to think.

The teachers thought for a while, but there was no answer. In the end, I could only wait helplessly for Li Han to announce the answer.

After the children guessed for a while, Li Han said the correct answer, "Because if you use it, it's too slow." Therefore, the geese choose to 'fly'. ”

Yes?

This time, even the teachers were stunned for a moment after hearing Li Han's answer, and then they reacted.

The teachers who reacted all laughed, and Deng Cui said, "Classmate Li Han, even we almost didn't react this time. Interesting, very interesting. And only you can come up with such a strange riddle. Li Han, do you have more riddles like this?"

Li Han said: "A lot!"

And so many more?

Deng Cui and the rest of the teachers were all very surprised, and Deng Cui said: "Li Han, this kind of riddle is really very interesting, and it can really exercise the children's unconventional thinking. Since Li Han still has many such riddles, he can write them all and publish a book. It will be very popular. ”

Hmm? Publishing a book?

This one... Li Han didn't think about it.
