Lessons activity is in: 
  • a clear sunny day
  • sunprint paper including a piece of flat plastic
  • flat plants and other objects to lay on the paper
  • tray of water

Collect flat plants, or other objects, to arrange. Spend time deciding on the design.
When ready, take the paper from its packaging and arrange the plants on it, then if possible lay a piece of plexi over to make them very flat and to stop them from blowing away.
Wait until the paper turns from blue to almost white.
Then take off the plants and immerse the paper in a tray of water. Wait until it turns back to blue, then remove from the water.
Dry the paper.

The sun exposes the parts of the paper that are not in the shadow of the plants.
The water fixes the design.
