The Palestinian – Israeli Environmental Secretariat (PIES) and Hazeva Field Study Center maintained in the summer of l998, a five-day ecological field laboratory in Sheizaf Nature Reserve for Israeli and Palestinian youth.  The group contained fifteen Palestinian and fifteen Israeli participants, ages l5 to l6.      The aims of the field laboratory were to expose Israeli and Palestinian adolescents to each other, in an exciting and interesting environment in a framework which would necessitate cooperation.  Sheizaf Nature Reserve was chosen because of its existing educational and scientific base.  It is located on the peaceful border with Jordan in an area suggested for international nature reserve cooperation, (together with the Jordanian Dana Nature Reserve), and in an area without political controversies.       The participants were exposed to different habitats in the desert over the course of their five-day field study.  They chose research subjects and developed their own research methods.  They asked questions, collected information and analyzed their data.  Finally, they summarized and presented their findings on posters.  All the activities, the learning as well as the social activities, were done in mixed teams.       The guides were both researchers who worked in Sheizaf Nature Reserve and social guides, experienced in guiding activities for Israeli and Palestinian adolescents.  The laboratory was managed in English.  A professional photographer videotaped the project and produced a video movie.
