Steve Spangler Science® Nature Print Sun Paper (30 Pack)
Make amazing white on blue prints with your favorite objects! Just place leaves, flowers, shells or whatever you choose on the photo-sensitive 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!<br>Recommended for children ages 6 and up.<br><br>How Does It Work?<br>The nature 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.<br><br>What Does It Teach?<br>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.<br><br>Science Fair Connection:<br>When the Sun Sensitive Paper reacts to ultraviolet light, it’s a pretty fantastic demonstration of UV-reactive materials. However, this awesome demonstration isn’t, by itself, a science fair project. To create a science fair project using the Sun Sensitive Paper, all you need to do is identify and use a variable. A variable is an aspect or factor of the experiment that you can control and alter. Here are some examples of variables that you could use:<br><br>Test different sunscreen brands or SPFs by spreading the sunscreen on the paper.<br>Try to find the best pair of UV-blocking sunglasses.<br>Once you identify your variable (don’t let us hold you back, if you have better ideas, use those!), start conducting your experiments. Make sure that you keep all other factors the same, though. Otherwise, you’ll have multiple variables!<br><br>What’s Included?<br><ul OLDSTYLE=color:black><LI>30 sheets of 5 inches x 7 inches sun sensitive paper</li><li>Make amazing white on blue prints with your favorite objects</li><li>Learn about the nature of sunlight and how light-sensitive chemicals work</li><li>Great Science Fair experiment</li></ul><br> <!-- STEM STEAM science light art artistic lights UV-reactive light-sensitive light waves fun learning sunlight sun color colors ultraviolet ultraviolet light sunscreen testing sunscreen test test tests paper nature papers nature print prints chemicals chemistry experiment experiments STEM STEAM science light art artistic lights UV-reactive light-sensitive light waves fun learning sunlight sun color colors ultraviolet ultraviolet light sunscreen testing sunscreen test test tests paper nature papers nature print prints chemicals chemistry experiment experiments -->

What will you learn about light, shadow, and photography? Before cell phones, computers, and even the first cameras, the Cyanotype was the origin photo-reproduction process. It uses ultraviolet light (UV) from the sun to change the color pigments in the paper. By Casting shadows from an object you might find, like a feather or a handful of buttons, you can create designs unaffected by the light that at first stay blue.
