This week, in our discussion board, we’re looking at physical properties of minerals that can be tested in the field. You’re going to choose ( Streaks,hardness, crystal form, color, etc.) and then select the 1 that you think is most important.

Back up what you say! It’s not enough to have an opinion – you have to back it up! What makes you think that streak is the most useful? Or what made you decide that color would be most helpful..

Just a discussion question – which need to be one to two paragraphs.
