Here are the steps we had to follow to make our prints:
1) Select different objects.
2) Take photo paper quickly out
of the black bag and arrange the objects on the blue side of the photo paper. 3) Put plexi on top of arranged objects so they stay in place.
4) Expose to the sun until paper turns almost white. 1-5 minutes depending on sunlight. Do not overexpose.
5) Rinse paper in water (change water ever so often). Let dry.

This is a great activity to be done in small teams to promote cooperation, e.g., two students work together and discuss first what objects they want to place on the photo paper and how they want to arrange them. They can also take on different jobs, e.g., one member of the team checks the color of the paper when it is exposing in the sun, the other team member rinses the paper in water.
