Earth Day has become the set date of April 22nd every calendar year. Since its inception back in 1970, it is celebrated to call the world's attention to our care of the Earth. As the day has evolved, teachers have found it a rich source of tie-ins for Science, Social Studies and Health curricula at varied grade levels, as well as Math and the Language Arts.
