Grades 6-10. In Discovering Electrical Systems, students look inside some electrical devices they use every day, identify components they find, and investigate how some of these components function in circuits. Students then build simple circuits into which they install each new component to get a first-hand account of how it functions. This Student eGuide allows students and teachers 24/7 access to their STC-Secondary content for this unit. Access for 32 students per year for 60 months.

Grades 6-10. Light can be applied in many ways to achieve varied results. Flashlights and televisions are obvious examples of how we can harness the power of light. But what about adjusting our vision, experiencing optical illusions, or sending information? Can light be applied to situations like these? Building on a preliminary understanding of the characteristics and behavior of light, Researching Optical Systems invites students to apply their existing knowledge about light to explore different optical systems, such as cameras, optical fibers, lenses, mirrors, and spectroscopes; how they are designed; and how they work.

STC-Secondary™ is a 16-unit, inquiry-centered middle school science curriculum developed by the Smithsonian Science Education Center (SSEC).
