Maps & Projections
📋 What it is
Every flat map distorts the round Earth somehow; a projection is a choice about which distortion to accept.
🗣️ Coach says
Here’s the honest truth: you can’t flatten a globe without stretching something. The famous Mercator map makes Greenland look as big as Africa — but Africa is 14 times larger! Knowing your map’s “lie” makes you a smarter reader.
🧠 Memory hook
Every flat map lies a little — a projection just picks WHICH lie. Mercator stretches the poles.
😂 Giggle
How do mountains stay warm in winter?
They wear snow caps!
😲 Whoa!
On a Mercator map Greenland looks about the same size as Africa, but Africa is really about 14 times bigger.
✅ Quick check: Why does every flat world map distort the Earth in some way?
Say your answer out loud first — then reveal.
Because the Earth is a sphere, and you can’t flatten a curved surface without stretching size, shape, or distance somewhere.
Understanding projection distortion makes students critical map readers, not passive ones.
