Lesson 1 · Free

Why can't the wind blow the haze away?

A pop-up storybook lesson about the Sumatra haze. Your child makes a guess, checks two sources, builds a cause-and-effect chain and tries a hot-tea experiment with you. Then they teach it back.

How it works

Seven steps from wondering to explaining

Every Yufena lesson follows the same seven steps. Kids get a clear path. Grown-ups get a simple prompt at each one.

  1. 1

    Ask

    Kids
    Notice something puzzling and ask a big question.
    Parents
    Write the question down together. Every question counts.
  2. 2

    Guess

    Kids
    Say what you think before looking anything up.
    Parents
    Don't correct yet. Ask, “Why do you think that?”
  3. 3

    Find out

    Kids
    Collect clues from the story, maps and pictures.
    Parents
    Read each fact together and point at the picture.
  4. 4

    Check

    Kids
    Compare your guess with what you found.
    Parents
    Celebrate a changed mind. That's what scientists do.
  5. 5

    Chain

    Kids
    Link the causes: this happened, so that happened.
    Parents
    Listen for “because” and “so”.
  6. 6

    Try it

    Kids
    Do a small, safe experiment at home.
    Parents
    You handle anything hot. Ask for a prediction first.
  7. 7

    Teach back

    Kids
    Explain it to someone in one minute.
    Parents
    Be the student. Ask one curious question.

Thinking skills that last

Each lesson is one story, but the habits carry over to every subject.

  • Curiosity

    Questions become adventures, not interruptions.

  • Reasoning

    Linking causes and effects with “because” and “so”.

  • Research

    Checking two sources before deciding what's true.

  • Visual thinking

    Maps, chains and drawings that make ideas visible.

  • Explaining

    Teaching it back in their own words.

We don't promise higher marks or exam results. We build thinking habits that help in every subject, and in everyday life.

Learn together

Screen time you share, not screen time alone

Yufena lessons are made to be explored side by side. You don't need to be a science expert. The lesson tells you what to ask.

  • A prompt at every stepTap “Parent note” on any page for a question to ask, and what a good answer sounds like.
  • About 15–20 minutesShort enough for a weeknight. Long enough to really think.
  • One screen, two explorersSit together, read aloud and take turns. The best part is the talking.
An example page from the haze lesson, with the parent note open

In the dry season, farms and peatland burn in Sumatra and Kalimantan. The smoke rises high into the sky.

For the grown-upAsk: Where does the smoke go after it rises? A good answer: up into the air, then wherever the air moves.

From the founder

Why I started Yufena

Hi, I'm Norman, and I'm a dad who gets asked a lot of big questions.

My son asks his at the busiest moments: in the car, at bedtime, halfway through dinner. For a long time I just looked up the answer. It was quick, and it was forgotten by morning.

So we started doing it differently. We turn each question into a small adventure: a story, a guess, a few clues, a kitchen-table experiment, and a chain of “because” and “so”. Then he explains it back to me. Those are the answers that stick.

Yufena Explorers is those adventures, shaped so any curious family can share them. I hope you enjoy exploring together as much as we do.

Questions parents ask

Good to know

What age is Yufena for?

Children aged 7 to 9. Younger siblings can join in with help, and older kids often enjoy leading the teach-back.

How much time does it take each week?

A story lesson takes about 15–20 minutes. During the pilot, families also join one live Zoom session a week.

What device do we need?

A tablet or laptop works best. On a phone, turn it sideways. Sound is optional, and there is nothing to install.

How much does the pilot cost?

The pilot price is still to be confirmed. Sign up to hear first. Nothing is charged until you say yes.

Is it safe?

Experiments use everyday household items. Anything hot is handled by a grown-up, and safety notes appear right on the page.

What about my child's privacy?

The free lesson needs no account and stores nothing about your child. This site uses no tracking, no cookies and no ads. If you join the pilot, we only use your details to talk to you about the pilot.
