Minerals- up Close and Personal!

Remember that a mineral is- “a naturally occurring, homogeneous inorganic solid substance having a definite chemical composition and characteristic crystalline structure, color, and hardness”. Whereas a rock is an aggregate of minerals. For example, basalt and granite are rocks, not minerals, because the composition can vary, and they are made up of many different crystals of several minerals. In addition, don’t confuse elements with minerals. An element is a single type of atom, as in hydrogen (H), sodium (Na), iron (Fe) and so on. Elements are shown on the Periodic Table used in chemistry. Minerals on the other hand, are combinations of atoms (elements), as in calcite, quartz, halite, etc. Although there are a few exceptions, such as copper, gold, silver, etc. that occur as “native minerals”, meaning that the mineral is composed of only 1 element. Review the definition of elements, rocks, and minerals in your text.Describe how your chosen mineral is used, and also conduct research to determine the geologic conditions in which it is formed, where it is found, how it is mined, its other uses, etc. Write a short essay about your findings.

How to Add Images to a Discussion PostReview your classmates posts before choosing a mineral to write about in order to choose one that that has not already been discussed.In the Topic Title text box for your post, enter the name of the mineral you have chosen.This is meant to be a creative assignment, so there is no single answer, rather each student’s primary post should be unique.Click on the Discussion in which you want to participate, then select “Start a New Thread”. After completing your post in the pop up window, select the “post” button at the bottom of the pop up window. Your post should now be visible in the discussion.Respond to the posts of at minimum three other students with insightful and meaningful comments and questions. Check back throughout the week for responses to your posts. Let’s have a useful discussion!
