This paper presents a collaborative educational experiment "The Death of the Dead Sea: A Problem Based Learning" that was applied in two governmental high schools in Ramallah, Palestine in the school year 2006-2007. The students' role was to raise awareness to the phenomenon of the saltiest lake that shrinks towards extinction. In spite of the enormous challenges in Palestine, the project was achieved successfully. Students learned cooperatively to fully understand the problem, its causes, consequences and possible solutions. The learning process oriented learners toward meaning-making over fact-collecting. They expressed their own views and opinions in creative modes and outcomes and celebrated their work in an exhibition that illustrated the problem to other students, teachers and to the local community.
