Eratosthenes determined the circumference of Earth by conducting an experiment Put his steps in order as they correlate to the scientific method?

Answer 1

1. State the problem: How can we prove Earth is round and calculate its circumference?

2. Make a 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.

3. Make observations and collect data: 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.

Answer 2

Make a 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.

Conduct an Experiment: Measure the angle of a shadow at high noon in Syene and Alexandria.

Make Observations: 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.
