On the way to take my children out for a long trip during the holidays, in addition to relaxing physically and mentally, another unexpected gain was that I discovered a documentary that my children and I love very much: "Thinking Like a Crow" is only about 10 minutes per episode,

In order to eat the food on the water,

crow noticed the small stones next to it,

throw them into the water with his mouth to raise the water level

"Think like a crow" is a popular science program specially produced by the Japanese NHK Education Channel. The program won the 55th Japan Science and Technology Image Award for Research and Development Excellence Award and the 2014 International Emmy Award.

is just like its name. This documentary hopes to guide children to learn to observe, think, reason independently, and then solve problems like crows.

My children and I felt after reading it:

• Easy and interesting knowledge;

• If we are Newton , it turns out that there are so many apples in life that we have ignored;

• Many Small experiments are also very convenient to operate at home. If possible, play with them and children will give you unexpected surprises.

seems relaxed and casual, but it is rigorous in design, and it always runs through four steps of scientific thinking: Observation - Hypothesis - Experiment - Research.

Each episode is divided into three sections, and the presentation method is different. Next, let’s take a look at it separately. The

section presents a total of 20 different phenomena in 20 episodes, all of which are based on some details that we are used to in daily life and are easy to ignore. They are simple and interesting.

For example, we all know that the train makes a "clang clang" sound when driving. But few people think: Why does have such a sound? Does all trains have this sound?

Observation:

Carefully observe the difference between the two tracks and you will find that if there are no gaps on the track of , there will be no "clang" sound when the train passes; on the contrary, if there are gaps on the track of , the "clang" sound when the train passes.

Assumption:

As soon as the wheel passes through the gap, it will make a sound.

Experiment + Research:

I thought it was over just observation. As a result, in order to verify this hypothesis, I also added simulation experiment : Leave a gap between the two tables at home and try to simulate the wheels with metal cylinders. When

enters the gap, it makes a "clang" sound

result is consistent with our assumption. Now, the puzzle of the train making a "clang" sound has been successfully solved.

Not long after watching this episode, when we went to the snow mountain to take the cable car 🚠, Jiujiu suddenly asked: Mom, why do our cable car always shake like this? Is the situation of

somewhat similar? I said to Jiujiu, "You look up and see carefully what the cable car has experienced when it shakes?"

For example, the little tortoise has grown up, and we can clearly see that its size has become much bigger. Its hard How did it grow up with tortoise shell ? Is the tortoise shell bigger as a whole, or is it that new tortoise shells grow layer by layer on the outside?

left: overall bigger; right: new layers of tortoise shells grow out of the outside, which is the case?

observation:

By comparing the tortoise photos with the tortoises when I was a child, it was found that there were 11 scales on the outside of

• , and there was no increase; there were 13 scales on the middle of

• , and there was no increase.

Assumption:

That is the first case - Turtle shell has become larger as a whole.

Experiment + Research:

Similarly, observation is only part of it. In order to verify the hypothesis (observation results), we need to continue to look for evidence.

enlarges the photos of the young tortoise to the same size as the current tortoise, and now there is a new discovery.

The width and narrowness of the black pattern are different

It turns out that the tortoise's shell becomes larger like this: ⬇

The size of the white part in the middle remains unchanged, but the black pattern is widening

Not only children, but we adults are also constantly being popularized. There are also many novel and interesting "secrets hidden in life" in this section.

One night, Jiujiu chose the picture book "Super Turtle". Jiujiu suddenly pointed to the turtle on the picture. He said, "This is a little turtle. You see, there are only a few circles of patterns on its back:

🔘 Mobius ring : an endless, endless ring, breaking people's understanding of space ⬇

Paper stick Rotate once and stick together, and get Mobius ring .

cuts along the middle to get a large ring

paper strip rotates twice and glues them together.

cuts along the middle to get two crossed rings

. This is like a magic trick for children!

I took the children to do Mobius band, and drew ant 🐜 on it, and let the children try to draw the route of the ant on paper along the ring.

Niu Niu said it was amazing. The ants kept walking and could walk to both sides of the paper! There are no more top and bottom.

We also tried to cut the Mobius ring by ourselves:

Jiujiu said, Ah turned into handcuffs. I immediately want to play "Police and Thief" 😂

Niu Niu said, if we cut again, let's see what it will become? Then try it!

Every time I "play" with the children, I will create sparks of thinking. The children are indeed "firmware upgrade" while playing!

In life, many artworks, sculptures, and buildings are also inspired by the Mobius Ring. If you see it again, you won’t feel unfamiliar. I guess you will probably know how to appreciate their beauty!

🔘 Ants "Draw the ground as a prison": ⬇

A line or a circle can block the ants' way

Many netizens said that it is because "Ants are afraid of the smell of marker " . Is this really the case?❓

Curious baby is online~ Jiujiu used chalk to draw a circle on the basketball court, and it actually circled the ants!

Let the child find the answer in his hands-on experiment. This is much more impressive than our unilateral mechanical input of the answer.

🔘Coins and wooden blocks floating on the water: ⬇

Coins will return to the middle position

Wooden blocks will always be close to the edge position

In the video, some give simple explanations, while others leave suspense. The child will ask, why?

I will tell them, I don't know either. Next time we play in the water, try it out by ourselves, maybe we can find the answer.

I think is much better for children to actively explore and think under the trend of curiosity than for adults to directly tell them an explanation full of mechanical concepts that they cannot understand. I have a lot of experience with

! Sometimes teammates will use many big words to explain to their children, such as surface tension , chemical structure ... The children are confused and even forget the original problem. An explanation that is too far from the understanding of children cannot benefit them at all!

Leave the problem to the children and remind them to observe and experiment by themselves and think about it by themselves. The process of exploring the answer will be full of rewards.

This part is Niu Niu and Xiaojiu’s favorite, and she burst into tears every time she laughs. Even if there is no specific plot yet, as long as you see these three "Yaredo" - the protagonist Dede Nion, they will inexplicably hit their laugh points.

This is the animation part of this film. The style of painting is cute, simple and interesting, without dubbing, only background music, and it still tests observation and understanding ability.

Although the three villains seem to be copied and pasted, their thoughts are very independent: will make a reasonable and well-founded hypothesis process, which is a bit nonsensical and a bit funny.

For example: Dedenion found a chair with with two legs short. How should I use this?

can be placed on bricks

or use slopes

For example: They found traces in front of the puddle - a straight line and footprints on both sides. Who left this?

Is it left by the dinosaur?

or was it left by a snake and a dog?

When a construction worker pushes the cart by, the answer to

is revealed.

For example: saw a round hole on the ice and connected to a straight groove, and they discussed, "How did this come about?"

was smashed by throwing an iron ball?

or the route of the submarine?

or is there a big shark passing by?

When the fisherman takes a long fishing net to catch fish, the answer to

is revealed.

I had a particularly big feeling when I was in school, the teacher who gave the answers directly must not be a good teacher, and this also applies to parenting. So, when a child asks a complex question, we can actually answer only a little bit, lead to observation and thinking.

These three wild "Yaredo" are like children with rich imagination and love to play pretend games. The world in their eyes is really different from the adult perspective! Everything they see, touch and feel every day is novel, so they want to know more and more.

Nothing is taken for granted! , whether it is right or wrong, thinking itself is a cool and meaningful thing.

This part is Aoi Yu takes everyone to do interesting small experiments, and the process is exactly the same as the scientific concept of this documentary:

• Observation: combines the experiment and asks questions;

• Hypothesis: aborts the experiment and gives three possible answers;

• Insert a short film, leaving time to think;

• Experiment + research: continues the experiment, verify it personally, and reveals the final answer.

is just at the end of the end, and it will arouse people's curiosity: only give a little explanation, and leave the rest to the audience to think and review the information themselves - Be a thinking crow .

has 20 independent experiments, no repetitions, the design is clear and concise, each of which is like a "prize competition", which makes me want to follow Youjiang to find out.

For example: Fix balloon on the cart, cover the balloon with a transparent box, and then push the cart. Guess what direction will the balloon tilt in?

Three options: 1. Facing back; 2. Facing forward; 3. Keep upright

Wujiu said, it must be leaning towards the body! Because of this, he has experience. Recently, he found that if he runs on , he can make a piece of paper press on his face and belly:

But the results of the experiment are exactly the opposite:

After a brief thought, let’s take a look at the truth!

Jiujiu is confused when you see this, why is ? Next time we will also find a box to try it out!

Another example: two burning candles, after one is destroyed, white smoke will appear. Then quickly use the burning candle to approach the extinguished white smoke. Guess what will happen?

Three options: 1. The one that is destroyed is ignited again; 2. The one that is burned is destroyed;

3. The one that is destroyed is ignited, and the one that is burned is destroyed at the same time, the one that is burned is destroyed

After a brief thought, let’s take a look at the truth!

? Why does it light up by itself? ? ? ? When the children saw this, big question marks appeared on their foreheads.

A colleague who has also watched an episode of this documentary said that even I don’t know the answer to those questions, let alone children, is simply desperate to death obsessive-compulsive disorder !

Hahaha, but this is exactly what I like about this documentary! Don’t give your children the answer, because they don’t understand, hahaha, not only will they not understand, but they will also lose the curiosity and interest that were originally ignited.

figured out a problem, but it doesn’t mean knowing the answer. Understanding requires a certain knowledge background and experience.

actively "find the answer" is much more rewarding than getting one answer directly. , and is not about your right or wrong thoughts. As long as you think, you will observe, and as long as you observe, you will discover the new world.

was ignited by the big names' parenting view and growth history. The interview documentary I finished in one breath, strongly recommend

BBC released the latest documentary last week, refreshing people's perception of infants and young children aged 0 to 2
