Description:

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth. Note: This experiment can only be done at solar noon twice a year; at the spring and autumnal equinox. These are the two times the sun is directly over the equator. You can do this experiment one or two days before or after the equinox to work around cloudy days. This resource includes a corollary story related to Christopher Columbus and his journey to India as well as winter and summer safety tips.
