Project SPECTRA! is a science and engineering program focusing on how light is used to explore the Solar System. Project SPECTRA! emphasizes hands-on activities, like building a spectrograph, as well as the use of real data to solve scientific questions. Lessons are available for middle school students, which can be easily adapted for use with high school or elementary students as well. Each lesson has a front page listing national standards in science and mathematics, prior knowledge required, materials, and time needed to complete the lesson.
