Explore How Light Is Needed to See Things

Subject Area

Overview

Explore how light moves and describe how an object in a dark space only becomes visible when light moves into the space and illuminates it. Interactive activities, time-lapse videos, and images are used to enhance student observations as they identify objects in the path of light or follow the path of light from its source.

Support materials include: Handouts and Teaching Tips. This resource was developed through WGBH’s Bringing the Universe to America’s Classrooms project, in collaboration with NASA.

The associated lesson plan Let's Explore Light provides more support for teachers and students, including handouts and materials for diverse learners.
