PROBLEM: Can you recognize local uses of aggregates?

HYPOTHESIS:

MATERIALS: Earth Science - Aggregates 

PROCEDURE: Look at samples and describe their characteristics. Review the different rock labs to help identify the components of the aggregates.  Use size, sorting, and roundness to help describe the constituents. Can you tell how the sample may be used (i.e. in flower beds, stairs)?
