his paper deals with the concepts of (femtosecond) and its applications, which is a unit of time that represents one millionth of a billionth of a second, and is one of the most important scientific discoveries of the Egyptian scientist Ahmed Zewail, for which he won the Nobel Prize in Chemistry, as this discovery contributed to understanding the mechanics of interactions. Chemical, as it was possible to benefit from   in many applications in the field of medicine, such as: treatment of eye diseases, dental fillings, and early detection of diseases, as well as in military applications. Of the prizes,  it is in the field of practical application, and   a unit of time equivalent to a billionth of a billionth of a second.  It is also called the fastest light laser in the world.  It has implications for the development of optical computers and mobile phones. The curricula of natural sciences are entrusted with dealing with the concepts of (femtosecond) and (Autosecond) and their applications in all stages of education,   This is also a global trend recommended by international projects and international conferences.   Accordingly, this paper recomm-  e nded the need to review the standard levels document for the content of science allotted for the stages of general education, as well as the standard academic standards document for the student teachers in the scientific departments in the College of Education.   Therefore,  it includes these concepts and their applications, and to suggest teaching methods based on the integration between science and technology to teach these concepts. Because of its impact on the development of creative and future thinking among learners, which in turn contributes to the development of societies, and the achievement of sustainable development.
