Reflection: Lesson Planning Weathering, Erosion, and Deposition - Section 4: Explore


Weathering From Acid 

The rocks I use for this activity are white rock I purchase at Home Depot.  The rock must contain some amount of limestone, but not every rock has the same amount.  You can purchase limestone chips online which would probably work as well.  If you purchase white rock and they aren't working, you can always dip them in baking soda before putting them on the trays for the kids.  The white rocks are already chalking so they students would not know it was baking soda.  The purpose is for them to see that acids will eat away at rock causing weathering.
