This 2 night, 3 day earth education program’s goal is to increase student knowledge of four key ecological concepts (energy flow, cycling of matter, interrelationships of living things, and change over time) and to deepen their feelings for the earth through observation, discovery, solitude, and immersion activities. The program begins two weeks before the visit when a map and letter arrive, inviting the class to become Earthkeepers. At the Earthkeepers Training Center (Cooper) they participate in a series of staff-led activities and students earn two of four keys that unlock boxes that reveal the secrets to becoming an Earthkeeper. Back at home and school the students earn the last two keys of the program by pledging to use less energy, fewer materials, visiting new natural areas, and sharing their knowledge and experiences with others.
