2. What is the Eratosthenes experiment?
Students measure
the circumference of the Earth
using simple means
Use ISE eLearning
tool to find
local noon
At that time they
measure the
shadow shaped
by an
one-metre stick
and they note it
They contact a
school on the same
medieval and they
exchange data
Using their data and their schools they succeed in measuring the
circumference of the Earth
