Cyanotype (sun print) is a photographic printing process that produces a cyan-blue print and is a great way to look at the structures of plant life. We can examine the lines and shapes of plant life by looking at the negatives left behind. Because the light sensitive paper is exposed by sunlight when objects are placed on the surface what is left is a clear outline and shape of the object. The 4th grade researchers used sun prints to investigate the structures of the plants in the leap area further. Comparing the structures captured to the sketches they made previously.
