Topics such as quantum physics, elementary particles, relativity theory, cosmology and others are among the most important branches of modern physics that are currently being studied and researched by scientists and physicists worldwide. Due to their complexity and the need for advanced scientific knowledge, these topics are not fully incorporated into the school curriculum and are taught as specialized courses in physics departments at universities. However, providing education on modern physics concepts to interested high school students is of great importance. A better understanding of phenomena and knowledge of the surrounding world, familiarity with new technologies and scientific innovations, the development of analytical and critical thinking skills, problem-solving abilities, and fostering a sense of motivation in acquiring knowledge can all be the effects of proper and accurate teaching of these subjects. Unfortunately, the Iranian schools curriculum do not have sufficient capacity for students to learn material beyond the textbooks and the learning process is limited to the prescribed textbooks. Developing educational content in the field of cutting-edge scientific knowledge for interested high school students can have a significant impact by using various methods such as self-study materials, e-books, creating films and animations, and other approaches. Therefore, in this research, we have focused on designing two self-study educational contents on the topics of dark matter and elementary particles for interested students in high school. Our aim has been to present the content in a coherent and understandable manner, using simple and elegant language consistent with the students' previous knowledge from textbooks. The prepared educational texts have been reviewed by experienced university professors and physics teachers in schools, and we have considered their valuable feedback to address any existing issues in the material. Finally, we presented the designed educational content to a group of high school students. The students provided us with feedback on the quality of the designed content by reading the text, answering the designed questions, and participating in the survey. In the end, based on the results of the eva‎luations, we made the necessary corrections in the text for better comprehension. In order to ultimately reach the desired content in accordance with the research objectives.
