Plan for the 2026-2027 school year with the calendar below!
Students in Mr. Griffith’s class recently got to experience a real-life “Camera Obscura” after a conversation about pinhole cameras sparked the idea to transform a classroom into one!
To create the effect, Mr. Griffith's room was completely darkened using cardboard and tape to block out windows and light sources. A sheet was then hung from the ceiling to act as the projection surface. After calculating the correct aperture size based on the distance from the doorway to the sheet, a small opening was cut into a piece of cardboard.
When the aperture was opened, sunlight reflecting off objects outside traveled through the opening and projected an image onto the sheet inside the dark room. Students were amazed to see the outdoor scene appear upside down and reversed, even watching people move past them on the other side of the door in real time!
The art activity also helped students connect the experiment to science concepts about the human eye. Just like the camera obscura, the eye uses the pupil as an aperture and the retina as the surface where images are projected. The brain then processes that information so we see the world right side up.
Such a fun and engaging hands-on learning experience!

This week, we are recognizing Mr. Douglas Meyer, a teacher at Logan Elm High School!
