Mineral Mine

There are several ways that minerals can emit light in addition to the light that is emitted from exposure to daylight or the light from normal light bulbs. Some of these ways involve special lamps that emit non-visible ultraviolet light (at least not visible to humans).Light from these ultraviolet lamps reacts with the chemicals of a mineral and causes the mineral to glow; this is called “fluorescence”. If the mineral continues to glow after the light has been removed, this is called “phosphorescence”.®(Property of Amethyst Galleries, Inc., )

Based on the above information, what type of minerals are on display in this exhibit?

Choose a partner. One person will wait outside of the room while the other goes in.

Partner 1: Choose a rock to describe. Write a detailed description of the rock when the black light is on. Use as many physical characteristics of your chosen rock as you can;however, you may not list its location, what case it is in, or what it is next to. You will have two minutes to complete your task.

Description:

After two minutes, hand your description to yourpartner waiting outside and time how long it takesthem to find your rock. Partner 2 must describe the location, what case it is in, and what it is next to.
