5 Measuring the circumference of the Earth
Over 2,000 years ago Eratosthenes made a remarkably accurate measurement of the earth's circumference. This project is a recreation of that measurement and requires collaboration of students in places at different latitudes on the earth to make shadow measurements, share data, use a spreadsheet (optional) to make comparisons, and then replicate and share their results.
