The experiment of Eratosthenes

Students will measure the region of the Earth using the method followed by Eratosthenes in the 3rd century BC. – Students learn how to measure Earth’s circumference using simple mathematical formulas.

Cognitive domain (processes)
to think critically and creatively: Students are informed about the innovative idea that Eratosthenes had to measure the region of the Earth.

Cognitive domain (knowledge)
procedural knowledge: Students learn how Eratosthenes actually did his measurement and attempt to repeat it.

Affective
to respond and participate: Students follow the teacher’s instructions and try to measure the region of the Earth on their own.

Psycomotor
to imitate and try: Students follow step by step Eratosthenes’ process and measure the region of the Earth in the same way.

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.

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

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