The EcoTeens Program is a hands-on, science based enrichment program offered by the Franklin Park Zoo. The program is open to youth in Boston Public Schools grades 9 - 11, and is designed to teach students about natural history and conservation issues, and to provide them with opportunities to develop leadership skills. Youth participate in the out-of-school time program during weekly after-school sessions, as well as every other Saturday sessions. In the 2008 program, they could choose to participate in one session (January through March, or April through early June) or in both sessions
