*  Complete the sentence, "Most rocks are made of _________."

*  Explain what a mineral is, listing the characteristics that all minerals share. 

*  Use simple laboratory tools (copper penny, hand lens, scratch plate, streak plate, dissecting needle) to investigate the properties of minerals.

* Given several samples of different minerals, classify them based on their properties.

*  Describe what is meant by the following terms used to describe mineral properties

           q hardness         q luster         q streak         q specific gravity (similar to density)    
   
      q cleavage         q color       q solubility       q odor

* Explain how to evaluate the mineral properties listed above for a given mineral sample. 

* Using a mineral identification key, determine the name of a given mineral sample based on its properties.  (For fun, visit the online mineral identification key provided by the Mineralogical Society of America!)
