In this lesson, students will create their own "camera obscura" out of a cardboard tube to explore and reinforce the fact that light travels in straight lines.
Cameras are now as ubiquitous as the cell phone. Billions of photos have been uploaded to the Internet now that everyone has one in their pocket. But
how exactly does a camera work?
The linked science lessons in this unit will look at the evolution of cameras through the lens of Physics. In this lesson, we will learn that light travels in straight lines, and it is this property that allows cameras to work. To explore this property, we will create our own "Camera Obscura."
This lesson is part of an integrated project called "Photographic Self Portrait." In this project, students examine how photographic self-portraits visually communicate who they are.
