Hello I am a student teacher in Australia and I am trying to design a lesson plan on making and using pinhole cameras. I want the students to be able to make their cameras cheaply and quickly. Has anybody tried using black foam core? What would be the recommended minimum thickness of cardboard? Can a piece of coke can be used for the shutter? My students are year 9/10 (about 15 years old). Any suggestions for my lesson plan will be greatly appreciated.
Regards, Lisa
