Day 69 - Seasonal Sunprints Holiday Experiment - Burlington Science Center

The Science Center gives a holiday break experiment to every student K-5 in the Burlington Public Schools.  This year’s experiment is called “Seasonal Sunprints.” Be sure to watch Ms. Pavlicek and Mr. Musselman’s video introducing the experiment and some exciting things you can do with your sunprints!

Seasonal Sunprints are made with photosensitive paper that changes color when exposed to sunlight. It can be used to create artistic patterns or as a tool to investigate the sun’s energy!
Sunprint directions:
  1. Pick FLAT objects you want to print. Lightweight objects can be held in place with plastic wrap.
  2. Place or pin objects on sunprint paper and keep covered until ready to expose to the sun. A dark trash bag works well for this.
  3. When ready, uncover and keep in sunlight until paper turns a very pale blue. (About 2 minutes)
  4. Remove objects and soak sunprint paper in plain water for 1 minute.
  5. Dry flat and think about the questions to the right while you wait.
Here are some questions to explore about your sun sensitive paper:
  • Why do you think a dark trash bag keeps the sunprint paper from changing until you are ready?
  • Would a light color trash bag protect the sunprint paper from changing too?
  • Sunprint paper doesn’t change under light from most light bulbs. How could sunlight be different from lightbulb light?
  • Why do you think plastic wrap can be used to hold lightweight objects in place?
  • What other materials could hold lightweight objects in place without affecting the sunprint?
The Burlington Science Center wishes you a wonderful holiday and new year full of investigations!  
                                Ms. Pavlicek, Mr. Musselman and Mrs. Hogan
We would like to thank videographer and Science Center IA, Charloette Hogan for filming our video.
