Eratosthenes determined the circumference of Earth by conducting an experiment. Put his steps in order as they correlate to the scientific method.
T
Conduct an Experiment: Measure the angle of a shadow at high noon
in Syene and Alexandria,
Make Observations: In Syene, the sun's rayfare vertical at noon. At
t the same time in Alexandria, the rays are 7.2 degrees from the
vertical
Draw Conclusions: The angle represents the amount Earth curves
11. between Syene and Alexandria. This is 1/50 of a complete circle and
1/50 of Earth's circumference.
