Science Buddies: "Ask an Expert"

My daughter is in 5th grade and this is her first science fair project to do and she has decided to do it over sun printing. We are just starting the project which is all Due in Jan. 2013. She has not done the project yet but she is wanting to do some research on it for her research paper, where would be some good places for her to look. We tried following the link provided in the project but wasn't sure where to go from there.

Any help would be greatly appreciated
Thank You,
Brenda

There are a lot of sources out there for information on sun printing, starting with the wikipedia page about it": http://en.wikipedia.org/wiki/Sun_printing

Of course, you won't want to use wikipedia as a "source", but it lists several primary sources at the bottom that would be ok.

One thing to note that makes it a lot easier to search for background information on "sun prints" is that they are essentially the same chemistry and process as blueprinting. A quick google search for "blueprinting chemistry" leads to numerous interesting and useful links.
