The Shape of the World Challenge

Here's the catch. You have to argue both sides of the oldest debate in science — using nothing but 6th grade math.

01

Prove the Earth is round.

Using only 6th grade math, make the strongest case you can that the Earth is a sphere. Think about shadows, distances, shapes, and what you can measure yourself.

02

Prove the Earth is flat.

Now flip it. Using only 6th grade math, make the strongest case you can that the Earth is flat. Take it seriously — the best answers are the ones that are hardest to dismiss.

The point isn't which answer is "correct." The point is learning to think in the unknown — to see patterns, build an argument, and hold two opposing truths at once.
