Eratosthenes’ measurement of the Earth’s Circumference

Students will measure the Earth’s circumference based on Eratosthenes’ experiment, which he carried out at 3rd century B.C.

Cognitive domain (processes)
to think critically and creatively: Students learn about the innovative way Eratosthenes used to calculate Earth’s circumference.

Cognitive domain (knowledge)
procedural knowledge: Students understand how exactly Eratosthenes performed his measurement and attempt to repeat it.

to respond and participate: Students follow the guidelines given by the teacher and perform the measurement of Earth’s circumference themselves.

to imitate and try: Learners follow the same procedure as Eratosthenes did and try to measure Earth’s circumference exactly as he did.
