Lulu and El Castillo
Did you know there is a pyramid in Mexico that can tell time? This video models how the light and shadow effect on the pyramid El Castillo in Chichen Itza, Mexico tracks time-the spring equinox and the agricultural planting season during zenith passage. The video links include instructions for making and using the model yourself. Visit our Educational Resources page for details.
