Scale Ladder
Order explicit educational scale anchors from microscopic to planetary while keeping synthetic reference values separate from subject measurements.
Smallest → largest
Reorder the five reference anchors.
Use the up/down buttons; no dragging is required.
- A few micrometres
The reviewed Mycobacterium tuberculosis record gives a typical 2–4 µm length. The 3 µm marker is the midpoint used only for this ordering exercise.
Open Mycobacterium tuberculosis in SEM - Hand-scale object reference
A 0.1 m object-scale marker is a synthetic educational reference. It is not a measurement of the linked Wollo opal.
Open Wollo Opal Play-of-Color - Built-structure reference
A 100 m marker is a synthetic built-scale reference. It is not a measurement of the Brooklyn Bridge.
Open Brooklyn Bridge Cable Web - Landscape-pattern reference
A 10 km marker is a synthetic landscape reference. It is not a measured width of the linked Erg Chech subject.
Open Erg Chech Dune Patterns - Planetary reference
A 10,000 km marker is a rounded planetary-scale reference. It is not a new measurement claim about The Blue Marble.

Reference anchors and assumptions
A few micrometres — ≈3 × 10⁻⁶ m
The reviewed Mycobacterium tuberculosis record gives a typical 2–4 µm length. The 3 µm marker is the midpoint used only for this ordering exercise.
Hand-scale object reference — 10⁻¹ m
A 0.1 m object-scale marker is a synthetic educational reference. It is not a measurement of the linked Wollo opal.
Built-structure reference — 10² m
A 100 m marker is a synthetic built-scale reference. It is not a measurement of the Brooklyn Bridge.
Landscape-pattern reference — 10⁴ m
A 10 km marker is a synthetic landscape reference. It is not a measured width of the linked Erg Chech subject.
Planetary reference — 10⁷ m
A 10,000 km marker is a rounded planetary-scale reference. It is not a new measurement claim about The Blue Marble.
Visual-literacy scoring rule
Correctness is not the finish line.
After every choice, the game explains the evidence boundary and asks you to name the observable clue separately from the representation or relationship classification. No answer changes canonical BVU data.
