The possibility of an integrated approach to the natural sciences on the basis of physics is proved. From generalized ideas accepted in modern science, such as the theory, the principle, the physical picture of the world, the idea of integration based on fundamental concepts emerges. The essence of the fundamental concepts from the positon of philosophy, psychology, physic is revealed. Possible approaches of fundamental concepts formation in the natural sciences course in a profile school are shown.
