아이들의 과학 흥미와 호기심을 키우는 부모의 비법 정리

I was born in Ulleungdo.

 Those so-called friends on land went to taekwondo gyms and stuff, but in my case, there was nowhere to go.

 That's why it's so, so boring.

 So, if you're bored, science isn't far away.

 Living expenses are immediately helpful.

 I want to give you an experience like this.

 First of all, there are people whose laundry smells musty.

 That sour smell is coming from the clothes.

 So, if we do our laundry using the common detergent, all of those smelly ingredients are turned into soap, so there won't be any smell .

 The reason why water bubbles burst is because the water wall becomes too thin in this empty space .

 If you put it in, the wall will remain thick because water won't evaporate .

 It is possible to create much larger drops.

 In this way, science can be applied to play as well .

 wow.

 Oh, the car doesn't explode right away.

 Wow.

 Look over there.

 hello.

 This is Garden Family Bruce Pin, bringing you only actionable educational insights .

 Everyone, today's garden guest is.

.

.

 We invited Professor Gwangryeol Lee, author of Elementary 1 Science.

 hello.

 hello.

 Hello Garden Family subscribers! My name is Gwang-Yeol Lee, and I am a researcher and lecturer in the Department of Science at Korea University .

  We are  researching nanotechnology that can solve environmental and energy problems.

 And I occasionally appear on Naver Channel and YouTube to  inform the general public about the usefulness of science, and this time I am also taking on the role of an educator who introduces science to children .

 In fact, aren't you teaching students who could be called our country's best students at Korea University right now ? When you look at the school, is there anyone like K who is good at social skills beyond studying and who you really look forward to in 5 years ? Now, I teach undergraduate students at Korea University and also provide master's and doctoral degrees at the graduate school .

 I'm kind to those friends I consider to be the best among the students .

 Are you nice? yes.

 It's good.

 And I'm not lying.

 When a result comes out, there is absolutely no sign of using that result to take advantage of others .

 He does more.

 Than others.

 And there is a tendency to teach and lead friends around you along .

 They are leaders.

 Friends who share what they have and  grow together with those around them do well.

 Those friends are now professors and  some of them rise to high positions in companies.

 Being kind is in some ways a social trait, but in our lab,  there are things we all have to do in common.

 For example, there are processes such as going together to clean, or washing and drying the dishes when they are in the experimental equipment that they used.

 Excellent children,  if they have time left, clean and put away the tools that others are using.

 It's altruistic.

 It's very selfless, and in the end, because you helped them, when they're really having a hard time and doing important work, other friends will help them too.

 So we do bigger things and achieve better results .

 Well, when I worked alone, I did three things.

 If I live alone and do three things, I join forces to do one or two more.

 Then, if it becomes five, this guy will have great achievements later on .

 Based on that, we can move on to the next step.

  It  may seem like an altruistic act at the time, but it actually benefits you.

 So in a way, it's clever now.

 He is young, but he is not calculating or clever.

  You can see that he is originally a kind person and has a heart to help others.

 So people aren't stupid.

 hmm.

 I feel it.

 I know that.

 I  want to work with him more because I know he is a kind and generous person .

  Even at an excellent school like Korea University, such children are excluded.

 The essence of that organization .

 Yes, that's right.

 So I've been in the US and been in a lot of different groups, right? About 20% of people are good .

 In any group, the ratio does n't seem to change much.

 yes.

  What is the big difference between children who excel in classwork and those who don't?  I've been showing signs since I was in the third grade of elementary school.

 is it so.

 yes.

 You only need to watch it for about 20 minutes.

 20 minutes? yes.

 Children with poor concentration cannot last 20 minutes.

 I'm in the third grade of elementary school.

 I go to elementary schools and give lectures.

 If you tell children a fun story, a lot of them will start learning like this after just 20 minutes .

 Ah, just listen in front and shake your body like this.

 All the children dance like this now .

 Some people look at me like this until the end  .

 And when we make eye contact, our eyes sparkle and we keep making eye contact until the very end .

 Meat nods and asks interesting questions.

 When and where will you learn concentration? Of course, there are innate temperaments as well.

 I don't mean the IQ you get from your parents.

 It's temperament.

 You can be born with the temperament to calmly listen to others and focus on your studies .

 And  although the temperament itself may be that of a child who likes to just jump in, the  ability to concentrate and listen during class can be learned at home.

  Friends in science or KAIST have interesting problems.

 If there is a math problem that needs to be solved, you have to solve it for three to four hours .

 I think that the difference is that you keep worrying about problems that can't be solved .

 The desire to focus and see it through to the end.

  The professor said that I did this much for my child's concentration and to help him/her finish the task .

 Could that be the case?  I  don't think anything I do will make a big difference.

 But when you're focused, it doesn't bother you.

 For example, I know a student in graduate school who is solving a very difficult problem .

 Even if it takes two or three weeks, I just  watch that guy work hard.

  Do n't let that get in the way.

 Then, those friends continue to focus like this and solve the problem.

 If your child is not playing a game on their phone, reading a book, doing math problems, or doing something related to schoolwork, you need to know how to wait a little past mealtime .

 In my case, my parents were a bit like that.

 When you were little, you used to make animals out of your car and stuff like that.

 Then, Mom and Dad, please prepare the food and wait a moment.

 This is not something you should eat quickly before washing.

 That was n't the case for me.

 This is important right now .

 From my perspective, when I  told my parents that I would finish this in a little while, they allowed me to do it all.

 Being undisturbed doesn't mean you should be cocky .

 It's about making my intentions clear  to my parents, but also letting them know that I need to focus on what I'm doing .

 That's the art of conversation .

 Right? In my parents' case, even when I was very young, they never made me do anything.

 Let me tell you a little bit about how I grew up.

 I was born in Ulleungdo.

  There were no cars in those days.

 To Ulleungdo.

  There  was not a single difference between the water and the celestial bodies.

 So, if you want to go to another neighborhood, you have to walk.

 I also remember taking a boat and going to another town .

 Those so-called friends on land went to taekwondo gyms and stuff, but in my case, there was nowhere to go.

 That's why it's so, so boring.

  That's why I 'm bored, so I have to find something fun to do on my own .

 It takes effort to do fun things.

 Going to the back line and breaking off something like bamboo and using it to make a water gun, a firearm, an arrow, a fishing rod and fishing, all of these processes require my effort.

 If you want to create something more performant, you need knowledge.

 For example, when I make a fireball and shoot it, I need to put a tail in front so that it flies straight to where I want it to .

 yes yes.

 You learn things like that by practicing them yourself.

 If I wanted to know a certain principle, my father would give me an encyclopedia of science books and other things .

 There were a lot of books at home.

 So, that's where I get the knowledge I need and then I try to apply it.

 yes.

 I tied something to the end of an arrow and shot it, and it flew straight and far.

 Then, you talk to your father and mother .

 If I do this and that, my father and mother will listen to it all .

 I think I continued to build my confidence while doing that.

 Parents My parents' characteristic was that they didn't interfere, but they always watched over us.

 I need some strength as I keep watching.

 But it falls apart.

 Then, if you look at it, there is another difference.

 My father went to the mountain again to take pictures.

 And my father also likes books now .

 If there is an interesting fact in a book, you  must tell it to your family.

 We also listened to it intently and talked to each other, and realized that there was a lot in the book.

 I guess I have to learn from books.

 I think I learned that attitude.

 Oh, Professor, if it's not a big deal, then your father and mother graduated from prestigious universities, and it  's not like that at all.

 So I am a very blessed person.

  I'd  like to talk about the viewing experience first.

 When kids were little, the thing they asked most was, "What is this?" How come it 's the most common? Right? But I think the role of parents is really important at this time .

 I don't know or I can't be bothered.

  The moment you tell them to stop talking nonsense, they will shut their mouths and never ask questions again.

 The reason this is important is that a scientist who doesn't give up is not a scientist.

 And there is no such thing as innovation without a spirit of giving up .

 Even if parents don't know much about something, they  can still praise their child when he or she asks such a question.

 That's a very good question.

 Let's try to find the answer together.

 Just by searching in books or on the Internet and going through the process of finding the answer together, you're  teaching me how to resolve my own questions when I have them .

 If parents read it in advance, when their children ask questions, mom and dad will already have a very positive attitude about the past and be able to answer.

 hmm.

 But what if a parent is the type of person who avoids the question by saying, “I hate science” or “Go ask that teacher” when the child asks a question?   What would happen to the child with such a parent? Wouldn't you have an attitude like, "If even your mom doesn't know, then it's only natural that you don't know anything ?" It's the same with things like cleaning and laundry that parents usually do.

 How can I become better at cleaning ? If you show an attitude of thinking and searching for the scientific principles hidden in it,  children will naturally think that they should do this.

  There really is so much science in the world.

  You might end up thinking like this.

 I think that kind of attitude is very important .

 My father didn't teach me anything in particular .

 yes.

 For example, create a woman.

 If you make a dog house, you have to cut it down.

 The tree.

 Then, it shows where to hold and where to use,  but from my perspective, wouldn't it be better to keep doing it like this? So  when your father tells you to try it once, you try it and it doesn't work out well.

 Dad, you get hit a lot.

 But then you start to wonder why that is.

 Why did it turn out like that? hmm.

    I think if I had naturally started asking myself questions when things got difficult, I would have gotten better results.

 When the results came out, I created my own logic.

 How did you do this? When I was in first grade, my homeroom teacher said something like that to me .

 When I write an answer, my answer is a little different from my other friends'.

 In the answer, please include the reason why.

 He was a friend who always wrote down the reasons.

 He said that he always wrote, "This is because of this and that" rather than just ending with a short answer   .

 In fact, the professor  asks Y questions to make his students, whom he cherishes, think like this.

 It makes me think more.

 You're a scientist because you do something for students.

 It's not always about coming up with a successful idea.

 Fail a lot.

 You'll probably fail a lot.

 So I show my students all the questions that I fail at.

 Kakao Talk is a bit on fire, but what if it were like this ? What would happen if this happened? I draw what's in my head on paper, then take pictures to show you, and show you the whole process.

 So, you said 2080 earlier? You see that and you follow it like I did.

  You keep asking questions and thinking, "Isn't this how it should be?"  And among them, I eliminate the most nonsensical ones first, and then test the ones that make the most sense later.

 That 's the teaching method I give to my students.

 My children are the garden.

 Jeongwon will later tell you something like this, Professor .

 I wish my dad had said something about his behavior that sparked his interest in science .

 Well, in that sense, I went home today and said to my wife, well, science is not far away .

 Oh, living is really helpful .

 I want to give you an experience like this .

 In that regard, can I ask you for a few tips? Well, first of all, there are people who have a musty smell in their laundry.

 Where does this musty smell come from? It 's because our bodies now produce oil.

 That's an organic acid.

 Organic acids.

 But now bacteria are eating this and shortening it .

 They all cut and eat it themselves and create short organic acids.

 Vinegar smells bad.

 yes yes.

 That vinegar is also an organic acid.

 That sour smell is coming from the clothes.

 So, the smell is created by bacteria and it is because of the organic acid .

 So this is a mountain.

 You should hear this.

  When an acid and a base meet, they are neutralized.

 In fact, when you use an alkaline detergent, it gets neutralized and creates a soap-like ingredient.

 yes yes.

 Then it won't smell like snow .

 So, if we use commonly used soda, or now called baking soda, or baking soda to do laundry, all of those smelly ingredients are converted into soap, so there will be no smell .

 yes.

 yes.

 Now imagine your child going outside and playing with bubbles .

 It would be nice if the bubbles could be this big, but the ones that kids have are useless.

 This kind of nonsense is over.

  It's so frustrating.

 When making a non-agricultural product, if you add sugar, sugar is very friendly with water.

 Sugar is sticky.

  There is something called hydrogen bonding between sugar and water.

 Then you don't have to know.

 But now we like each other .

 Because of this, the water doesn't evaporate well.

 The reason why water bubbles burst is because the water wall becomes too thin in this empty space .

 If you add sugar, the walls will remain thick because water will not evaporate.

 It is possible to create much larger drops .

 In this way, science can be applied to play as well .

 wow.

 Oh, it doesn't burst even if you kick it.

 Wow.

 Look over there.

 Also, if you close the bathroom door and take a shower, wo n't the mirror become dirty and you won't be able to see your face ? yes.

 When that happens, if you apply something like shampoo there and wash it with water, that area will look clean.

  Let me tell you why that is .

  Whether it's shampoo or soap, they all contain a lot of active ingredients.

  The so- called activator is the tail of the oil component .

 hmm.

 And the head part is so-called hydrophilic, meaning it likes water.

 If you think of it as having a head that likes water and a tail that likes oil,  when you apply this to a mirror, the glass will hang on to this head part .

 When you look in the mirror, the tail is towards us.

 Right? So this tail hates water.

 Because it's oil.

 That's why water droplets don't form.

 Now, we can apply it in that way .

 So, for example, if you go to the swimming pool and your goggles get wet, you can wipe them with shampoo or something like that and they won't get wet.

 In the case of the soap we use, yes, yes.

 It looks kind of the same.

 It has a head and a tail, and there is Na+ in the head part .

 It is a sodium cation, but tap water contains a calcium cation, which plays the role of two sodium cations .

 So when there are calcium ions in water, one calcium atom ends up with two tails .

 What if we look at the molecule since it has two tails ? It all just looks like a bunch of oil .

 That's why soap bubbles form in water .

 This is now soap .

 And now, after the water droplets in the water dries, a white precipitate forms.

 That one has calcium carbonate in it.

 Limestone.

 But these soapstones and limestones  are both weakly basic and weakly alkaline.

 So what should I do about the alkaline properties ? If you apply an acid such as vinegar or citric acid, you  can completely clean the faucet.

 You can use this kind of neutralization reaction to clean things like that.

  Just having these things can make life a lot more fun and useful.

 hmm.

 Is n't there science all around us? This is the science of life.

 Science is not useless.

 If you look at the contents here, there are  so many things to do at home, such as cleaning and playing.

 Kids really need to try this.

 If you try, it will remain in your body.

 Things I've done for fun .

 And what were the things that I really enjoyed doing? And things that I can explain in a language that I know.

 These are the things that are truly self- knowledge.

 I don't know about anything else, but I hope that parents who watch today's video and want to make science education more interesting  remember this one thing .

 Could you please give me some advice? yes.

 In order to fully benefit from education, not only in science but also in any subject,  who should be the subject of education?    Many parents like it when their children read a lot of books, not just the things they find out on their own because they are curious and the things they do with their own hands and bodies.

 There  won't be much left.

 Even if it is just a little bit of knowledge, the things I have internalized will last a long time .

 And if there is a strong sense of joy that comes with that experience, things  like your parents' smiling faces or things you did because you had so much fun may be remembered for a long time .

 And I need to be able to explain .

 hmm.

 A concept that cannot be explained is not something you know.

 So, what I can explain is that these are things that children remember for a very long time.

 So, what parents need to do is  help their children gain these experiences and gain knowledge.

 Rather than interfering too much, parents need to create an environment, provide tools and materials, watch over them, and respond positively when their children approach them.

  Isn't that what parents need to do now? And more importantly than all of this,  I think it's important that the family values ​​continue to be maintained.

 Does life end when you finish studying? No.

 There should be no conflict between a child's class and the peace and happiness of our family  .

 Shouldn't we fight over studying ? hmm.

 So, I think the ultimate value we should pursue is how we can make children study with enjoyment, and by allowing them to  spend a lot of time with their parents while they are growing up, so that the family can share those experiences and grow together in the same space and time    .

 Everyone, how did you like today's video ? If you found today's video helpful, please subscribe and like .

 We would also like to ask for your continued interest in Professor Lee Gwang-yeol's Elementary Daily Science .

 Oh, it really contains  a lot of scientific knowledge that can be applied in everyday life and interesting stories, so I highly recommend that you read it .

 Professor, thank you for your valuable time today .
