Students get to explore how photography works without darkrooms! In cyanotyping, the UV rays from sunlight will develop the specially prepared paper, turning a deep blue. Students will experience the amazement at making their own photographs. You can use the provided negatives, or make your own with transparency paper and a laser printer. This lab is appropriate for students in middle school and high school.
This is part of a series of lessons on Light in Science from Mr. Ripps.
