As an extension to a science unit on light and color, students in 5th grade constructed pinhole cameras out of oatmeal boxes and are taking pictures with them. We have one small light leak in each camera (the pinhole) and the exposure time is between 2-3 minutes. 5th graders have shown they can stay very still and quiet for that amount of time! We are also experimenting with ghost images and movement. Unfortunately we cannot control for variables like the weather and sunlight!
