Sun-Sensitive Paper for Solar Art
The sun allows life on Earth to survive and thrive. You can show your students the power of the sun with photosensitive paper, making art with solar rays.
Humans use solar power for many practical reasons, such as providing eco-friendly energy to our homes, but teaching students the power of the sun can be challenging because it’s hard to see the sun’s rays. Using photosensitive paper in your science lessons can make this more tangible for students. With Steve Spangler’s Sun-Sensitive Paper, you can turn sunlight into beautiful works of art. Your students can create white-on-blue prints with any of their favorite objects.
Try placing leaves, flowers, shells or any other item you can think of on the photo-sensitive paper and leave it laying in the sun. Remove the objects after a couple of minutes and rinse the paper in water to reveal a piece of sun art. Your students will be amazed at how the paper turns white wherever the object was placed, encouraging a discussion about the science behind the art.
Recommended for children ages 6 and up.
What Does It Teach?
Kids can learn about the nature of sunlight and how light-sensitive chemicals work. You can talk about how photos are developed as each layer of chemicals on the film react to photons of different color. This can also help students understand the different uses and impacts of sunlight.
•This kit includes 30 sheets of 5-by-7-inch (12.70 by 17.78 centimeters) Sun-Sensitive Paper.
How Does UV-Sensitive Paper Work?
The paper is coated with light-sensitive chemicals, which react to light waves and particles when exposed to the sun. When you place objects on the paper, they block the light and turn the sheet white, while the paper around the area remains blue. After the silhouette appears, dunking the sheet in water stops the process in its tracks, preserving your images on the photosensitive paper.
A Perfect Science Fair Display
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 a science fair project on its own. To create a science fair project using light-sensitive paper, you need to identify and use a variable. A variable is an aspect or factor of the experiment that you can control and alter.
Need ideas for variables that you could use? Test different sunscreen brands or SPFs by spreading the sunscreen on the paper or try to find the best pair of UV-blocking sunglasses. Once you identify your variable (the possibilities are endless, so if you come up with better ideas, go with those), start conducting your experiments. Make sure that you keep all other factors the same or you’ll end up with multiple variables that will invalidate your experiment.
Frequently Asked Questions
Can you explain how I “set” the image?
It is really easy to set any image, all you have to do is place it on the sheet by itself. If you were to use tape on the edges, then the tape would leave its imprint on your image as well.
What types of objects work best?
Any object will work as long as it blocks the sun. Objects that are semi-permeable or ones that don’t lie flat against the paper may let some light through to cause the developed image to be less defined.
What size is the paper?
You get 30 sheets that measure 5 1/2” by 7 1/2”, which is just the perfect size for your class.
How long does it take to work?
It works best if you leave the image in the sun for about 2 minutes and then bring it in without allowing the covered part the be exposed to sunlight. Let the paper sit in some water for about a minute and then your image should be ready to displayed.
