The main objective of the physical geography is to give a meaning to the natural environment. It is only possible with the implementation of the observation method to make the students perfectly understand the physical geography topics, in laboratory environments allowing the participation of all senses in teaching activity. In physical geography teaching, observation method is only applicable with the trips as its laboratory is natural environment. There is a need for new methods in teaching of physical geography topics to motivate the students, increase their interest towards the topics, bring them different perspectives, make the complex issues easier to understand for them, let them have quick and permanent learning and to make the abstract concepts concrete for them. There have been carried out studies and different theories to this effect. We have developed a new strategy using the latest technology against the problem of difficulties in observation-trip method in secondary schools. The basis of our strategy is to create a learning environment with "Physical Geography Teaching with 3D Simulation" model. With this model, the students will be able to experience the fieldwork and the teacher will be able to use the observation method.
