The purpose of this study is to develop a lesson plan that will facilitate the instruction of socioscientific issues and the acquisition of twenty-first century skills. To this end, a lesson plan comprising four hours of instruction was devised and presented in comprehensive detail. Three distinct activities were devised and executed as part of the lesson plan. The initial activity is the Nuclear Energy Panel Event, which serves to elucidate the nature of nuclear energy. The second activity is the 6 Thinking Hats Technique and Different Perspectives on Nuclear Energy Activity, which permits the consideration of the nuclear energy issue from a multitude of perspectives. The third activity is the Let's Create Dilemma Cards Activity with Canva, in which a nuclear energy poster was designed to facilitate comprehension of the positive and negative aspects of nuclear energy. Aspects that were liked, disliked, and wanted to be changed in the implemented activities were determined by the activity evaluation form applied to the students. According to the findings obtained from the activity evaluation form, students expressed positive opinions about the activities implemented. It is thought that the designed and implemented lesson plan will serve as an exemplary socioscientific lesson plan for teachers and teacher candidates.
