Rocks Made of Air

Pores are small openings that allow air and moisture to permeate the surface of a material. Porosity is the measure of these voids relative to the solid structure. Porosity is a significant consideration in many fields, including ceramics, hydrogeology, construction and metallurgy.The independent variables in this experiment are the kinds of rocks, and the dependent variable is the amount of water they retain. The constants are the containers, the amount of water and the conditions. The goal of this project is to explore the concept that rocks are not completely solid or exactly alike.Rocks have pores of varying sizes, and water fills these pores seeming to “absorb” the moisture like a sponge.
