On Monday, August 21, 2017 there will be a Total Solar Eclipse. This will be the first time the Moon's umbra has touched the continental United States since 1979 and the first totality to span the country coast-to-coast since 1918. From within parts of Oregon and through 14 states to South Carolina, the Moon will completely hide the Sun for a few brief moments, turning daytime to an eerie kind of near-twilight, where the Sun's ghostly corona, bright stars and planets, and other phenomena associated with total eclipses become fleetingly visible. Every part of the country will see at least a partial eclipse. This eclipse offers a chance for virtually every elementary teacher in the United States to participate in a rare and special teaching opportunity. It also allows educators to enhance their science instruction while increasing the level of science literacy in their classrooms by employing a cross-content approach. This article examines how to derive the greatest level of literacy from the eclipse via interdisciplinary lessons.
