A Creative Solar Printing Science Project

This is one of my favorite springtime projects to do with the kids. We learn how the sun can cause a chemical reaction.

You can buy this special paper that has been treated to create images with various objects and the sun. You place the object(s) on a piece of paper and then put the paper in sunlight for 1-2 minutes. The solar printing is finished when exposed areas of the paper turn white. The area underneath your object will be blue since the sun didn't hit that area. Take the paper out of the sunlight and remove the objects. Run water over the paper and then let it lay to dry.
