What are some uses?
Test the Effectiveness of Sunglasses
Test the effectiveness of sunglasses by placing them in
the sunlight and covering the detector with the lenses. If the beads
remain white, then the sunglasses are blocking harmful ultraviolet rays.
Test the effectiveness of Sunscreen.
Spread a layer of a commercial sunscreen on the detector tube,
place it in direct sunlight and observe if the beads change color or
remain white. Try this experiment with a number of sun blocks and sunscreens
with different SPF ratings.
Other investigations that could be conducted using the UV-Detector
include testing the effectiveness of UV absorbing window film, transparent
colored filters, windshields of most automobiles, TV screens and computer
monitors. These are only a few of activities that can be conducted
using the UV-Detector however; a much more extensive program has been
developed as an interactive CD-ROM
The UV-Detector comes complete with easy to follow instructions,
an explanation of how the detector works and a series of suggested activities
for its use. A smaller version of the UV-Detector is also available in
an economical pack of five
