Tomorrow will be our test on Chapter 3: Minerals. You should be able to calculate the density of a substance given its mass and its volume. The units for density will need to be properly treated as well. And you should certainly know what we mean by a substance and how a substance is different from a mixture.
Your decisions about the identities of the minerals you tested yesterday should be based on the observations you made. In the Conclusion section of your lab sheets you should make clear how you reached your decisions for each of the three minerals you tested. Because it is not easy to determine density and exact values for hardness on Moh's Scale with our equipment, you may not be certain of your choices. But you should be able to make the best choice from the list of minerals that you were given. Assignments:
