Day 47: I Saw the Sign

Friday, 17 October 2014


We took a little camera obscura I made outside today. It was super easy to see the sun’s image on the back wall of the box. When we turned to less bright objects, however, they were tough to see. These girls, though, not only saw the sign but then broke into song.

This short activity is a great way to demonstrate how simply a pinhole camera forms images. I only wish our image was brighter. Maybe a larger pinhole would be helpful.

This day last year: Day 47: Ray Tracing
