The issue of energy is one of the major issues that have plagued humankind in today's world. The traditional fuel energy is decreasing day by day, the harm caused by the environment to human beings has become increasingly prominent. The world has turned its attention to renewable energy, hoping that renewable energy can change human's energy structure and achieve long-term sustainable development. Therefore, to enhance students' ability to learn, practice and explore energy from a young age is of great significance and far-reaching significance. The following is the author's lesson in the use of solar energy for my colleagues reference. First, the activities of the target 1. Experience solar energy development and utilization of science
