Laboratory 3B: Mineral Identification
Due Points 15 Questions 17
Time Limit None Allowed Attempts 2
Instructions
ATTENTION : You must complete Laboratory 3A: An Introduction to Minerals BEFORE you complete this lab. Lab 3A will teach you about
the characteristics we use to describe minerals. Lab 3B will have you use the characteristics to identify minerals.
If you do not first complete Lab 3A, Lab 3B will be difficult/impossible.
Terry has filmed a video (see below) that will introduce you to mineral identification techniques used in this lab to classify 14 unknown mineral
specimens.
This lab guides you through identifying 14 common minerals. We have given you 2 attempts. This means that you can submit the whole quiz up to 2 times.
You should answer all the questions about each mineral before you submit the first time. Then, you should receive feedback about which questions you got
wrong and can go over the questions with your T.A. during your weekly discussion session. Then you can complete the 2nd attempt to correct previous
errors.
NOTE: Canvas appears to autosave your answers to the quiz. If you've made progress and need to take a break for whatever reason, you should be able to
exit the quiz without submitting. When you return to the quiz, your answers should be saved. There is no timelimit besides the time that the quiz opens and
closes.
