The present proposal was designed as an interdisciplinary approach in purpose of fulfilling the tutoring need in the Global Warming phenomena. Research concerning students’ perception on the phenomena was utilized while realizing the proposal.  The tuition subject was planned on carefully designed problems of the real world and followed the 7E learning cycle model structure. Three different instruction models were employed, which are two experiments, a video of Antarctica and a documentary. Specifically, the first experiment relates to the contribution of CO2 to the Global Warming Phenomena, while the second one depicts the impact of the energy retention of the Earth to the temperature of the Earth and the glaciers and sea ice. This project was put into practice by third class, high school students, during the year 2007-2008 and was evaluated by the rest of the students’ community through a presentation by the end of the school year.
