Rock Solid? An ordinary piece of rock looks solid. But take a closer look at certain types of rock, sandstone or limestone, for example, and you will see many tiny openings called pores. Pores can be thought of as veins through which oil, gas and water can flow. Have
each student bring a small piece of rock to class. Examine the rocks under a microscope to
see which are most porous. Use library resources to categorize the rocks and determine
which would most likely contain oil.
