For this activity you will need to watch the short video(s) for each mineral. You have been provided with key characteristics for each mineral on the page with the mineral videos. You will need to identify each mineral by comparing that information with the table below to determine the mineral name. Once you have determined the mineral name you will need to create an excel table with the following columns and in this order:

Sample Number, Luster, Hardness, Fracture/Cleavage, Streak, Color, Other properties, and Mineral name.  You will be submitting this completed table. You need to put the samples in numeric order in the chart.

Each mineral with the corresponding information is worth 3 points.
