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.

Respuesta :

The order is: C, A, B

The statement of the problem:

How can we prove Earth is round and calculate its circumference?

Hypothesis:

If the sun casts shadows at different angles at the same time of day in different places, we can determine how much Earth curves.

If the Earth was flat, the angle measured at different places at the same time of the day would be the same.

Observation:

In Syene, the sun's rays are vertical at noon. At the same time in Alexandria, the rays are 7.2 degrees from the vertical.

Thus, the correct order is: C, A, B.
