Nanomaterials with their amazing and useful properties are becoming more popular in human life day by day, and getting to know the properties of these particles can have a significant impact on the quality of human life. The void of concepts related to nanotechnology as one of the effective techniques in achieving the goals of sustainable development is very felt in the experimental science laboratory books of secondary school and it is very important to include the basic concepts of this science in the teaching materials of different educational levels. Teaching any concept in a practical and laboratory manner has a great impact on the deep learning of that concept, and nanotechnology as a science that has experimental and laboratory origins, in this research, we designed a simple experiment to prepare magnetic iron oxide nanoparticles in the school laboratory, in order to familiarize students with Nano science is practical and finally, by identifying the structure of these materials by magnet and scanning electron microscope (SEM), we explain the concept of nano and its importance in sustainable development and its different applications in life.
