Today, our classroom transformed into a mineral
identification lab! Students were excited to examine a collection of
"mystery rocks," each with its own unique set of clues. To
discover what was inside these hidden specimens, they put their geology skills
to the test with a series of exciting experiments.
Testing the Clues:
Color:.
A classic first step! Students
carefully observed the color of each mineral.
Using the Mohs Hardness Scale, they tested how easily a mineral
could be scratched, revealing its strength.
They rubbed each rock on a streak plate to see the color of its powder, a key
identifier.
Students observed how the minerals
reflected light, learning about metallic and non-metallic types of luster.
A simple but effective test for certain
minerals, they used a magnet to see which rocks were attracted to it.
Under a special
light, some rocks glowed, adding another fascinating layer to their
investigation!
