Friday Science

To wrap up "All Those Secrets of the World" we discussed how in the 1400's people thought the world was flat and that by sailing toward the horizon they would eventually fall off the edge of the world. Christopher Columbus figured out that the earth was a sphere by observing a butterfly and orange.

On a flat world, a ship (or puppet) would always be seen,
it would just get bigger the closer it got.

With a spherical world, you wouldn’t see the ship as it begin to sail.

You would then begin to see the top most part of the ship
or puppet ears in our demonstration.

Finally you would see the whole ship or puppet.
