This interdisciplinary activity combines chemistry and art through the construction and use of a pinhole camera. We focused on the chemistry of the black and white photographic process as the science component of this activity. The reactions involved are good examples o photochemistry and multiphase chemical reactions, since the light sensitive materials (silver halides) are in the form of a gelatin emulsion of microscopic crystals.
Information on the history of photography and the chemistry of black and white photography, references and sources of additional related activities, and student photographs taken with pinhole cameras are available as supplementary materials. The material can be accessed as a pdf file using Acrobat Reader, or as one Microsoft Word document, eight JPEG documents, asn two GIF documents. The JPEGs and GIFs can be viewed using Photoshop. The word and photoshop documents have been compressed into sit (for Macintosh) and zip (for Windows) files.
Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
Take JCE along on your outreach missions. Copies of the Journal, guest access to JCE Online, our publications catalog, and more are available for your participants.
