Webinar: Measure the Earth with your Students

Presented by Charles Woodford

Over 2000 years ago, Eratosthenes found an ingenious way to measure the circumference of the Earth with amazing accuracy. This experiment, which can be adapted to elementary or secondary levels, is a multidisciplinary project which shows the power of ingenuity to solve problems. It combines concepts in math, geography and astronomy and allows students to make an amazingly accurate measurement of the Earth - something they probably never thought they could do! We’ll show you how to do this project with your students and maybe even collaborate with schools around the world.

Join us to learn how to do this measurement on September 22, during the fall equinox! 

Registered participants will also have access to the resources and recording of the live webinar.
