Dependent Variables- The amount of material dissolved over time
Control Variables- 
-The amount of acid dripped on materials
- Shape of material
-Same solution of acid
- The way each material is measured for mass
- Same Location

Independent Variable: Materials tested - granite, concrete, limestone, and bronze.

Dependent Variable: The change in mass of materials (granite, concrete, limestone, and bronze) after being dissolved by acids at 24 hours, 48 hours, and 72 hours

Control Variables: Amount of acid combined with materials; amount of water combined with acid; Time intervals that dissolved material is observed; Temperature of acid and water; pH value of acid rain solution
