The Streak Test is a better test than looking at a mineral's observable color.
The Light Test is one that tests "light transmissivity". We were able to see whether a mineral's transmissivity was transparent, translucent, or opaque.
The magnetism test was a test that tested just that... A mineral's magnetism!
We used a fingernail, a penny and a nail to measure a mineral's resistance to abrasion (fancy way of saying we were testing the hardness of a mineral). We measured using Mohs Scale. The scale ranged from a 1 (soft), 5 (medium), to a 10 (hard).
