Today we used the sun and special sun print paper in an exciting experiment of light, shadow and color!
Sun print paper uses ultraviolet light from the sun to change the color pigments in the paper. By casting shadows from an object, like leaves, buttons or keys, we can create designs, which will, unaffected by the light, at first stay blue while the rest of the paper becomes more pale or faded. After we submerge the paper in water the first reaction is being stopped and as the paper dries, which is the development stage, the colors reverse!
How did we create our fascinating
and beautiful sun prints?
Step 1: Arrange your materials on a sheet of clear acrylic glass
"This says I love Mama!" - Soren about a small wooden heart
"I want a baby heart and a leaf." - Fay
"Open door! I got all of them. I got key. I got another key. For that door." - Connor, arranging keys on the acrylic glass
Step 2: Place the arrangement on top of the sun print paper and expose it to direct sunlight for about 5 minutes. Watch closely as the color on the paper fades!
Step 3: Quickly submerge the paper in water and then let it dry in a dark place
"I want to see it change colors." - Soren
We also enjoyed the sunshine in the outdoor classroom today!
