Mineral Identification; Mineral Key:  Using the key, identify the mineral samples by testing for the various physical properties.  You will create your own dichotomous key to identify 6 mineral samples.  (120min) Practice how to use a dichotomous key.  It will be on the lab practical portion of the Regents Exam.
Rock Classification -- Geo Tour.  An introduction to the three classifications of rocks.  (80min)


Rock ID:  No handouts for this lab.  This was a practical exam demonstrating your ability to correctly classify rocks into the three categories of igneous, sedimentary, or metamorphic.  (160min) Click here for a review sheet on classifying rocks.
Physical and Chemical Weathering. Chop up an apple, drop crushed chalk and a whole piece of chalk into dilute acid, and drop alka-seltzer tablets into different temperatures of water. (80min)


Virtual River:  River Discharge.  Be sure to scroll to the bottom and click on River Discharge, not River Flooding.  (40min)
