I remember when I was in graduate school, three Japanese professors came. Once I had dinner with him. When we wiped our hands with paper, they slowly took out handkerchiefs from their pockets, wiped their hands easily, and then folded them back.
These details, I felt very shocked at the time!
Later, I founded this science museum, learned a lot of scientific experiments with the Japanese, and made a video with only 2 or 3 minutes. In fact, it took a long time to make it.
Later, I learned the story of the god of sushi, and I learned their citizens' spirit of pursuing perfection.
In order to do a good job in science and education, they have produced many science and education programs for children to cultivate their scientific thinking methods.
I have shared with you before "Ah! Design, thinking like a crow, Pythagoras device, etc.
Many links in these programs are not simply instilling knowledge points, but guiding children to observe, think and finally draw conclusions.
Recently, a popular science program for Japanese children, Square of Science, was discovered by NHK TV. I think it is comparable to "Ah! Design, think like a crow and other good programs.
What I like most about this program is that it will guide children to discover the laws, beauty and wisdom hidden in daily life from ordinary things around them from a brand-new perspective.
The difficulty span of this program is still a bit large, but the activities inside can allow young children to participate with their parents.
Official website recommended the age from 3 to junior high school, but as an adult, I am still very happy and feel incredible.
Different from the previous programs of the Department of Science Education, the Science Square does not cram scientific knowledge, but focuses on cultivating children's eyes to discover science from daily life.
For example, do you know what an object looks like when it is enlarged?
For example, do you know what stripes are like on zebras?
For another example, do you know which side of the banana is facing up?
When you see the above three questions, do you suddenly have a brain like mine, and you also have such doubts. What do they look like?
In fact, there are many "incredible" things around us that can't be ordinary.
Next, Xian Dad will take you to experience this cartoon, and the way to watch it is introduced at the end of the article ~
Look in the middle.
This program is to help children notice the "incredible" places through various methods and angles of discovering scientific problems, and make the scenery that was once commonplace in their eyes look different.
The episode that impressed me deeply was Looking from the Middle.
Do you know what the strawberry will look like if it is cut in the middle?
This program interviewed many people. See what they think of strawberries ~
A little boy thinks that strawberries are red around and there are particles in them.
The little girl thinks that the center of strawberry is white and hollow, and the surrounding is red.
A young woman thinks that the center of strawberry is pure white and gradually turns red.
Everyone draws different strawberries, some have lumps inside, some have holes inside, and there are white stripes in the middle ... What do strawberries look like after being cut?
Don't worry about the answer, here you can find a blank piece of paper and draw a picture with your child.
This is really a place to play children's imagination! Maybe there will be a surprise ~
The following is a picture drawn by my colleague's daughter (the strawberry shell is too big to finish). She said the strawberry was red next to it and white in the middle.
Actually, strawberries are cut like this. Is it what you think?
If children are interested and want to continue this game, they can find other fruits to solve the problem.
The program didn't end here, and more in-depth research was conducted.
If we look closely, we can see that there are many white stripes on strawberries. What are these white stripes?
When watching the video, you can also ask your child. This is a scientific question! Will inspire children to explore ~
From another angle, cut the strawberry horizontally, and you can see that the center of the strawberry is a little red, the surrounding color is white, and there are white stripes outside. What are the white stripes of strawberries?
The project also uses a special machine to observe the inside of strawberries in three dimensions ... horizontal rotation ... vertical rotation. ...
Here we can clearly see the structure and trend of the internal veins of strawberry, which are responsible for transporting water and nutrients from the top to the surface of strawberry.
In order to confirm this observation, the program made further experiments. In a glass of water, add the pigment, and then put the strawberry with branches into the cup.
If the white stripes bring nutrients into the particles on the strawberry surface, the blue water should reach the particles on the strawberry surface.
The experiment began.
First, let the strawberries stay overnight in the blue liquid. When you cut the strawberry, you can see that the roots of the strawberry are blue and the stripes are dyed blue.
However, the experiment has not yet achieved its goal, so the program makes strawberries absorb more blue water.
Four days later, we cut strawberries again. This time, we can see that the white stripe is dark blue, and it is dyed to the tip. The particles on the surface of strawberries are also blue.
White stripes may bring nutrients into the grain. ...
What are the lines on the surface of strawberries? You can think about it ~
Look, in this short 10 minute, the children guessed and explained, and gained a lot of incredible new knowledge, which is very good ~
How many corn kernels are there?
Another episode, which I like very much, is how many corn kernels there are.
The protagonist of this episode is corn, and this theme shocked me again! A corn, do you know how many corn there are?
This project requires children to count the number of corn kernels on a corn.
What is the real motivation for such a boring thing to go on? I'm still curious when I think about it. I took you to count the rice grains before, and there were also people. )
Soon the children finished counting, and the number of corn grains on each corn was different. Next, the children put corn on the table according to the number of grains.
By observing the corn, the children found many conclusions.
Some children say that the number of corn kernels is roughly between 450 and 600, and most of them are around 500.
Some children also said that the grains on the corn with more grains are smaller, and the grains with less grains are bigger.
Another boy said that the number of grains in this 1 1 corn is even.
Is this an accident?
In order to avoid mistakes, next, use another method to calculate the number of corn particles.
There are 10 corn kernels in a row, which is arranged in 10 row, so it looks very clear.100 ... 200 ... 300 ... 400 ... 500, plus the last digit, the number of corn kernels is 534, which is still an even number.
Let's look at it from another angle. From the top, then from the bottom, and now from the side, the corn is continuously arranged neatly.
Is every column even? Let's count together.
The results after counting tell us that not every row of corn grains is uniform.
But in this process, another feature is found, that is, the number of columns of corn is even, so are all corn even? Find a corn count.
By calculating the number of columns of corn, it is found that the number of columns of corn is even. Why is this?
Next, a child breaks the corn from the middle and looks at the cross section of the corn together.
The number of corn kernels visible in the cross section is the number of columns, so it is 16 if calculated.
Next, let's take a closer look at this section. Did you find anything different?
Yes, we can see that it is divided into two parts from the root and finally has two studs. Two corns form a group.
This is the secret of "even number", have you found it? You did a good job. Son, there is a surprise here. Archimedes rushed out of the bathtub.
Taking advantage of common things around me and taking children to discover their scientific knowledge is one of my favorite points. I used to give students interesting annual ring lessons, using wood.
Small rings are printed with information about climate, geography, diseases and pests of different times, from which children can analyze a lot, just like the "wrinkles" on the forehead of the old man.
last words
In addition, there is an animated short film in the middle of each film, which is the original painting drawn by the famous picture book writer Shinto Yixiao. The music is lovely.
It will also mention some doubts that children often have.
For example, why is the day after tomorrow tomorrow?
Why do people get bigger and bigger, not smaller and smaller?
Also, can the spilled milk in the cup return to the cup?
Children's imagination is always imaginative, but it's just a manifestation of children's thinking, don't you think?
In this way, this program decomposes complex scientific concepts into experiments or games that children can understand, and guides them step by step.
Moistening things silently, children have subtly gained the scientific spirit of dare to question, dare to explore, boldly assume and seriously verify.
The only regret is that the Chinese subtitle version has not been found yet. Parents of younger children can take their children to play games after reading it.
Older children can guess while watching, and most of the content can still be understood ~
