Make amazing white on blue prints with your favorite objects! Just place leaves, flowers, shells, or whatever you choose on the photosensitive paper and place in the sun. Remove the objects after a couple of minutes and rinse the paper to "fix" it. Congratulations, you've made a permanent piece of sun art! Kit includes 15 or 30 sheets of 5 1/2" X 7 1/2" sun-sensitive paper.

What's included?

• 15 or 30 sheets of 5 1/2" X 7 1/2" sun-sensitive paper

How does it work?

The sun print paper is coated with light-sensitive chemicals, which react to light waves and particles when exposed to light. When you place objects on the paper, they block the light and turn white while the paper around them remains blue. Water stops the process and fixes your images on the paper.

What does it teach?

Learn about the nature of sunlight and how light-sensitive chemicals work. From here, launch a discussion about how color photos are developed, as each layer of chemicals on the film react to photons of different color.

Experiment

Test your sunscreen! Cut a sheet of sun sensitive paper into squares. Collect sunscreens with different SPFs and spread one on each square. Expose them to the sun, and see what happens! Record your data and document your research. Is a sunscreen with 45 SPF more effective than one with a SPF 15?
