S.T.E.A.M. Solar-powered Prints

A "cyanotype" is a photographic print made when UV light is exposed to a photo-sensitive paper.  It changes the chemical structure of the paper, but only the parts of the paper that are exposed to light.  When placed in water, the UV-altered areas remain a permanent deep blue color, while the chemicals on the surface wash away and expose white paper.


Attached are pictures of the incredible 4th grade cyanotype projects as part of our S.T.E.A.M. project.  Bravo!
