| Unifying Concepts and Processes | Constancy, change and measurement | K-12 | Scale includes understanding that different characteristics, properties, or relationships within a system might change as its dimensions are increased or decreased. |
| Physical Science | Light, heat, electricity, and magnetism | K-4 | Light travels in a straight line until it strikes an object. Light can be reflected by a mirror, refracted by a lens, or absorbed by the object. |
| Transfer of energy | 5-8 | Light interacts with matter by transmission (including refraction), absorption, or scattering (including reflection). To see an object, light from that object-emitted by or scattered from it-must enter the eye. | |
| Science in Personal and Social Perspectives | Science and technology in local, national, and global challenges | 9-12 | Individuals and society must decide on proposals involving new research and the introduction of new technologies into society. Decisions involve assessment of alternatives, risks, costs, and benefits and consideration of who benefits and who suffers, who pays and gains, and what the risks are and who bears them. |
| Content Area | Grade Levels | Content Standard | |
|---|---|---|---|
| Physical Sciences | Light Energy | 3-5 | Recognize that light travels in a straight line until it strikes an object or travels from one medium to another, and that light can be reflected, refracted, and absorbed. |
| Physics | Electromagnetic Radiation | 9-10 | Recognize and explain the ways in which the direction of visible light can be changed. |
| Technology and Engineering | Communication Technologies | 9-10 | Explain how information travels through different media, e.g., electrical wire, optical fiber, air, space. |
| Communication Technologies | 9-10 | Identify and explain the applications of laser and fiber optic technologies, e.g., telephone systems, cable television, medical technology, and photography. | |
