Digital Twins: Copy a Real Place

Find out how real places get copied into 3D, then explore a spot in our school and plan its stop on our virtual tour.

A giant statue used to stand in this cliff. It was destroyed on purpose. But people can still explore it in 3D today. How? Guess with the person next to you.

Your mission today

Match real places to the reason they got a twin.
Try two ways to scan a building in 3D.
Explore your spot in our school like a reporter.
Plan your tour stop: hotspots, sounds, and a map.
Share your stop with the class.

Step 1

What Is a Digital Twin?

A digital twin is a 3D copy of a real thing or place. It's so detailed you can walk through it and explore it, almost like being there.

A digital twin isn't a photo of a place. It's a copy you can explore.

Tap each real thing to see its twin and why someone made it.

If you could make a digital twin of any place in the world, what would you pick? Why?

Step 2

Why Copy a Real Place?

Museums and history experts don't make twins just for fun. Each twin solves a real problem. There are three big reasons:

It could be lostFires, wars, and storms can destroy a place.

It's already goneSometimes a place is destroyed before anyone saves it.

It's hard to visitDistance, money, or safety keep most people away.

Match each place to its reason

Which reason feels most important to you?

Why? One sentence.0 / 200

A digital twin can outlive, out-travel, or out-repair the real thing.

Step 3

How Do You Make One?

There are two main ways. Try both on this building, seen from above. Gray dots are spots the computer isn't sure about yet. Pink dots are locked into the 3D model.

Pick a method, then start scanning.

Model: 0% done

A thousand photos or a million laser pings: either way, something real becomes something you can explore.

Step 4 · Get up and go

Be a Real-Space Reporter

Heritage experts decide what's worth showing in a famous temple. Today you do the same job for a real spot in our school. You don't invent anything. You notice what's really there.

My spot

The space your instructor gave you

Before you go

I'll ask before going into an office or staff-only area.
I'll stay quiet near any room with people working in it.
I won't take photos of people.
I'll stay with my group and my adult.

Stand still for one minute

1:00Look and listen. Don't talk.

Something I see that I never noticed Something I hear Something older or newer than everything else

Ask an expert

Ask an adult who knows this space. Write their job, not their name.

Who? (their job) My question The coolest thing they said

Step 5 · Back in class

Plan Your Tour Stop

A great tour stop isn't the whole room. It's the 2 or 3 things a visitor will remember.

3 hotspots

A hotspot is a real object a visitor can click to learn more: a trophy case, a mural, a sign, a machine.

The real objectWhat a visitor sees or learns when they click it

The hook

What's the first thing a visitor should notice when they arrive?

Sounds of this space

If a visitor stood here for 30 seconds, what would they hear?

Map it from above

Draw the walls and big objects. Then tap to drop the ★ where visitors arrive, and dots 1, 2, 3 on your hotspots.

My big idea

When a visitor arrives at my space, I want them to

Step 6

Share Your Stop

Tell the class about your stop.

Fill in your plan in step 5 first.
