Providing sun-safe environments, schedules, and activities; teaching and modeling sun-safe behaviors; and implementing a sun-safe school policy are ways that schools can help protect children from sun overexposure and lay the foundation for a healthy lifestyle at an early age. This article presents the SunWise program and examples of classroom activities that can be used as part of a solar science curriculum. The structure of the school day enables SunWise lessons to be taught and implemented right away. The SunWise tool kit provides maximum teaching flexibility--elements can be used as stand-alone teaching tools or to complement existing classroom activities and/or school curricula. The tool kit's activities are standards-based, inquiry-based, and innovative in their design. Furthermore, they provide another vehicle through which classes and schools can involve parents and the community in a common cause.
