Last summer・・・
I also want to use TRIZ like my elder brother.
"One day, a screw that stuck to a magnet
was magnetized. How should we do tomagnetize the screw? I want to study
about it as my summer homework."Son
1st Grader,Junior High"It is interesting!
The personification might beable to be used.
Let's try together!"

We looked up only the "Meaning of the word“ in a dictionary.
When the magnetic field is applied from the outside tothe material, the phenomenon of the object's wearing
magnetism is called a magnetization.

A variety of methods will be useful for me.
In the following research,
I want to accomplish it by myself.

My teacher didn't
understand my report.
I was very sad.

Son
This research was
too hard for me.

MotherWhich is father’s purpose?
A solution of the problem?
Or a brainwash of themethodology?
We should reflect for easy
understanding of our report.
And, I should have added
and subtracted“volume” and “speed”.

On the other hand, I want
the teacher to listen toan unknown methodology
in sincerity, “What's this?”

①Enjoy it together not teaching.
②Using the method isn‘t the purpose.
③Moderate “Volume” and “Speed“.
（ Don‘t be too greedy. Don’t work too hard. ）④Continue the motivation of“Curiosity” and “Happiness”.
⑤ Praise and Admitting.
Let's do creative imagination in a different field or daily life!

Personification and SLP are very useful.
