Classroom activity:
The Ultraviolet Project

Teachers gathered in the courtyard to see the effect of the sun on ultraviolet sensitive beads and to discuss how these could be used in the classroom.

As the beads absorb ultraviolet rays, the colors intensify. Teachers moved in and out of the sun to see the effects on the beads.

They discussed various ways that these beads might be used to demonstrate the effect of ultraviolet rays emitted from the sun and to demonstrate the different amounts of protection from harmful ultraviolet rays.

Instructor Richard Sedlock tests the effectiveness of his sunglasses against UV rays.

The Ultraviolet Project is an activity developed by Rod Benson.
