### 科学启蒙：重构教育叙事

Mark Rober 以一场充满震撼感的实验开场：将液氮灌入两升装的塑料瓶并拧紧瓶盖，使其发生“剧烈的、自发的、快速的解体”。这一看似简单的实验背后，其实蕴含着深刻的物理学原理。当液氮气化时，体积膨胀了 700 倍，由于塑料瓶无法承受如此巨大的内部压力，最终导致“能量释放”。

这不仅是展示实验，更是在传递一种教学范式。正是这种压力构建了物理过程，而这也是大炮发射炮弹、Nerf 发射器发射飞镖、以及 T 恤大炮发射 T 恤的底层逻辑：通过构建压力并在一个方向上突然释放，推动目标物产生加速度。这种通过现象演示直观地理解世界的框架，正是引发“顿悟时刻”（aha moment）的关键。

<summary>Original English Source</summary>
I want to start off tonight
with a two-step experiment.
For step one,
I've got a two-liter bottle here.
It’s half-filled with liquid nitrogen
that’s negative 320 degrees Fahrenheit.
As you can see, it's violently
boiling off into a gas,
just like boiling water does
on a hot stove,
because to this freezing-cold
liquid nitrogen,
the nice comfy air
in this room is super hot.
But here’s the catch:
the gas form of nitrogen
occupies 700 times
the volume of the liquid,
so you’ve got to be really careful,
as it’s turning into a gas
you don’t trap it in a small container --
like if the lid was screwed on top here.
So then for step two,
I'm going to go ahead
and screw the lid on top.
And when I do, if everything
goes according to plan,
the contents of this bottle
should experience
what we refer to at NASA
as an “energetic, spontaneous,
rapid disassembly.”
(Laughter)
It's going to explode.
(Laughter)
All right, here we go.
Put that on.
OK, now, this is going to be --
Oh, you know what?
What the heck, might as well
throw these on top.
(Laughter)
This is going to be real
boring until it's not.
If you don't like loud noises,
cover your ears.
But according to my calculations,
things could get real interesting here
in about three, two, one.
One.
(Laughter)
One.
I said one.
I’m just kidding -- it’s really impossible
to actually calculate exactly --
Whoa!
(Cheers and applause)
Let’s go!
(Applause)
How's your jet lag now?
(Laughter)
Alright, my apologies,
my friends in the front row,
you should be warned,
it will get worse before it gets better.
(Laughter)
I'm like science Gallagher up here.
So a lot of people would look at that --
Thank you, yeah.
You keep those as souvenirs, actually.
Please don’t throw them back
the whole time.
A lot of people look at that and be like,
"Oh, neat, the ping-pong balls exploded."
But what actually happened
is so much cooler.
Because as more and more
of that nitrogen turned into a gas,
those gas molecules
got more and more crowded
as they pushed back
on the plastic molecules
comprising the walls
of the two-liter bottle.
And then eventually,
the pressure got so great,
it got so crowded,
the walls of the two-liter bottle
lost the game of molecular Red Rover,
and all the gas came rushing out.
But where could it go?
Because it can’t go down
or to the sides --
trash can's too thick.
Therefore, the only option is to go up,
and since all the ping-pong
balls are in the way,
they just happen to go along for the ride.
But here's the really cool part.
This is exactly how
cannons fire cannonballs.
It's how Nerf blasters fire Nerf darts.
It's how T-shirt cannons fire T-shirts.
And for my friends in the front row,
it’s how straws fire spit wads.
I'm just kidding.
(Laughter)
The trick for all those is you
simply build up enough pressure,
you suddenly release it in one direction
and plop whatever you want in the way
to go along for the ride.
And I love when I get
like, that aha moment.
When I understand the world around me
with a new framework.

### 隐藏蔬菜：激活好奇心

Mark Rober 提出了一种名为“隐藏蔬菜”（hiding the vegetables）的教学风格。他认为，教学中最致命的错误是使用那些抹杀好奇心的术语，例如“考虑一个体积为 V 的刚性容器”。这种抽象和枯燥的描述，只会让学生对科学失去兴趣。相反，教学的核心应该在于“让它变得重要”。

所谓的“隐藏蔬菜”，是指将科学原理“伪装”在极具感官刺激的活动中，让学生在不知不觉中掌握复杂的概念。例如，制作一个 15 吨的果冻池来演示科学方法；通过障碍训练场演示松鼠终端速度（terminal velocity）的原理；或者通过制作极其复杂的 Glitter Bomb 投递包裹来演示微控制器的工作方式。这种教学方法之所以有效，是因为当学生的注意力被极具吸引力的内容所吸引时，他们会对其中的科学知识产生深度的关联。他强调，学习最有效的方式是将其与“粘性经验”（visceral experience）挂钩。

<details>
<summary>Original English Source</summary>
But even more than that,
I love giving that to other people.
This is why, for the last
15 years, once a month,
I've uploaded a free science
or engineering video to YouTube
to my now 75 million subscribers
who also have a taste
for those aha moments.
And the videos --
(Applause)
The videos can range anywhere
from an elephant toothpaste volcano
that sets a world record
to a satellite that's orbiting
above us right now that we built,
that you can upload
your picture to for free,
and it will display it on a screen
and then give you a selfie in space
with the Earth photobombing you.
(Laughter)
Or even a soccer goalie [that]
moves back and forth at 40 miles an hour,
and then we track
your shot so effectively,
not even the world's
greatest player can score on it.
(Laughter)
Sorry, Ronaldo.
(Laughter)
And 16 billion views later,
what I've learned is I can't teach you
if I don't have your attention.
But if I can get your attention
with something remarkable,
well, now I suddenly have something
to attach the learning to.
This is why it kills me if someone's like,
"Oh, I don't like science
because it's boring."
But at the same time, I get it.
Because instead of learning about pressure
the way I did with these ping-pong balls,
a lot of the times
it’s something like this --
with curiosity-murdering phrases
like, "consider a rigid
container of volume V."
(Laughter)
It’s a freaking trash can, all right?
(Laughter)
And don’t get me wrong,
there is a time and a place for equations,
but for a generation that is growing up
on TikTok and YouTube,
you have to make it matter
with something that gets them
to lean forward in their seat.
Something that ignites a little
curiosity fire in their brain.
And we need that today more than ever.
I like to call this style of teaching
“hiding the vegetables.”
(Laughter)
For example, it's really boring
if you make a video
about the scientific method.
But what's not boring
is if you make a video
about a 15-ton Jell-O pool
you can actually belly flop onto.
And in the process,
I'm going to sneak in
all six steps of the scientific method.
What's also really boring is memorizing
an equation about terminal velocity.
But what's not boring
is you point out that squirrels
are one of the only mammals
that can survive a fall from any height
at their terminal velocity.
And then, in an effort to keep them
from stealing all your birdseed,
you set up an eight-part Ninja Warrior
obstacle course in your backyard,
and in the process,
what you might find
is they will voluntarily
demonstrate this principle for you.
(Laughter)
It's a very true story.
(Laughter)
There's also a ton of super boring
microcontroller tutorial videos online.
So when someone came by
and stole a package from my porch,
I decided to dedicate a year of my life
to making the world's least boring
microcontroller tutorial video.
Step one: you make
a bait package like this.
And on the outside, you have something
like a picture of headphones.
But inside, instead of headphones,
you have this contraption.
And at the top there is a cup that spins
a pound of the world’s finest glitter.
You have four phones that will record,
then upload their footage
to the cloud in real time,
and as the pièce de résistance:
a very uncharitable amount of fart spray.
(Laughter)
That's foreshadowing.
And then step two:
you have the thief come by,
and when he lifts the lid,
takes it home --
of course -- it sprays the glitter
followed by the fart spray.
I should point out, by the way,
this whole video was sort of
a modern-day homage
to the greatest film of a generation.
I'm talking, of course,
about "Home Alone."
And so the thief here, who’s pretending,
is none other than my buddy
Macaulay Culkin.
(Laughter and applause)
And so then for step three:
what you and Macaulay are going to do
is you're going to make 20 of these,
put them on porches all across America,
and it won't take long
before you start getting back
some incredible footage like this.
(Video) Hello.
Machine: Keep the change,
you filthy animal.
Person 1: Whoa!
Machine: Hello.
You guys give up?
Or are you thirsty for more?
(Fart spray)
Operation “Whoever Smelt It,
Dealt It” initiated.
(Laughter)
Person 2: Oh.
Machine: Operation
"Butt Trumpet" initiated.
(Laughter)
Person 2: Oh.
(Fart spray)
Person 2: Alright, alright.
Alright, we get it, OK.
Smells like ... in here.
(Laughter and applause)
Mark Rober: By the way, I was watching.
And when that thief was about
to lift the lid on the glitter bomb,
not a single one of you was looking down
or was on your phones.
I had your undivided attention.
And that makes for the most
fertile brain soil,
because learning is best when
it’s attached to a visceral experience.
Basically, if you feel something here,
you remember it here.
This is why memorizing
a boring equation is hard.
But you know, remembering
that song you sang as a teenager
that made you feel
all those feels, that’s easy --
and you remember every single lyric,
you know, 30 years later.
And to be fair, I didn’t come up
with this style of teaching --
all great teachers know this.
For me, it was Mr. Malloy.
He was my high school statistics teacher.
Hello, Mr. Malloy,
if you're watching this.
And he was great,
not just because he had a killer
Doctor Evil impression --
(Laughter)
Or because, and I mean this
with all sincerity,
he had way better hair than whatever
I was trying to figure out here.
(Laughter)
He was great because he made it matter.
Like encouraging us to use
what we learned in statistics
to predict where our
arch-rival soccer team
was going to kick their penalty kicks.
And it worked.
He was so good at attaching
emotions to learning.
He was so good at hiding the vegetables.

### 系统性革新：科学教育的破局

在分享了自己对教师职业的敬意以及对现行科学教学资源陈旧的痛点后，Mark Rober 宣布了一项重大计划：他与团队历时两年半，研发了一套完整的 3-8 年级科学课程。该课程不仅涵盖了所有州级的科学标准，更融入了其过去 15 年来总结出的“隐藏蔬菜”教学精髓。

这套课程包括了引人入胜的演示视频、简洁易用的课堂幻灯片以及经过精心策划的科学实践实验，目的是让教师能够以低成本、高效的方式激发学生的科学兴趣，并将教师定位为课堂的“英雄”。最核心的是，他宣布这套完整的课程体系将完全免费。他强调，这不仅是一次教学方法的 disruption，更是为了培养下一代能够解决复杂问题的科学探索者，让科学学习变得如同魔法般引人入胜。

<details>
<summary>Original English Source</summary>
And the thing is, with a really good
teacher, their impact is immeasurable.
Just like Mr. Malloy impacted his students
and we're now, in turn,
impacting the world.
That's why I love teachers.
I think they have the most
important job on the planet.
In fact, please.
(Cheers and applause)
I've said for like a decade,
my dream job is to be
a middle-school science teacher,
and I will be.
But until that time --
and buckle up,
because this is the first time
the world is hearing about this --
for the last two and a half years,
myself, with a team of about 50 people,
including some of the best
science teachers in the country,
have been secretly working
on a full science curriculum,
and it uses all the tricks I’ve learned
from the past 15 years
on how to hide the vegetables.
(Cheers and applause)
And the reason we're doing this
is because it breaks my heart
when I see teachers who
get paid salaries [that],
as a society, we should be ashamed of,
spending their own money
on resources that totally suck.
(Applause and cheers)
So it's got everything they'd need,
from banger videos the kids
are going to beg to rewatch,
that demonstrate the science --
yes, that is a wrench in an MRI machine,
because how else am I supposed to talk
about the invisible magnetic
fields all around us?
It's got ready-to-teach
classroom slide decks
that are super clean and easy to use.
And then it’s got these really thought-out
curated science demos
where the kids get to viscerally
interact with the science
that the teachers can make
just with stuff they have
lying around their classroom.
The idea is that together
we teach the classroom,
and the teacher becomes the hero,
as we engage the students
in real science and engineering
they actually care about.
We're starting with grades
three through eight.
It exceeds all the state
science standards,
but most importantly,
it’s exactly what science class
is meant to be:
super freaking fun.
(Video) Your teacher and I are about
to launch this class into hyperdrive.
Let’s go!
[You've never]
[Had a class]
[Like this]
We’ll build stuff,
ask a ton of questions
and even smash a few things along the way.
If everything goes according to plan,
you'll see the world around you
in an entirely new way.
Kristin Bell: Oh my God,
that’s crazy.
MR: Buckle up. It’s going
to be a wild ride.
It's basically magic,
but science.
Which makes it cooler than magic.
Mr. Beast: I knew it felt too light.
MR: What do you guys want to do now?
(Cheers and applause)
The world has evolved,
and teaching science
is long overdue for disruption.
I'm happy to report that of the teachers
who are assigned to teach the pilot
lessons to their students,
because of our ability to explain
complicated things simply
and for our very unique experience
in solving the science motivation gap
for 15 years,
95 percent of the teachers
said that when we're done,
they would want this to be
their full science curriculum.
And so the idea is you combine
incredible teachers
with incredible resources
to get this explosive output,
sort of like you'd expect to see
if you combine this bucket
of boiling water
with this trash can
of freezing-cold liquid nitrogen.
(Laughter)
So to all those teachers
out there in the trenches,
I want you to know
reinforcements are on the way.
In fact, a bunch of the videos and lessons
are already available right now,
and we'll finish the rest
over the next four years,
because I know this will be the most
important thing I do my whole life.
And even though this is going to cost us
$60 million to make,
my official declaration tonight
is every single lesson plan,
every teacher training,
every original class demo
will cost exactly zero dollars
and be 100 percent free
for all teachers forever,
as we work to ignite
those brain fires of curiosity
in the next generation
of big problem solvers.
(Cheers)
Thank you so much.
(Cheers and applause)
Thank you.
(Cheers and applause)
Thank you.
(Applause)
