Geologists are like detectives or sleuths. They examine the circumstantial evidence after the fact — at the 'scene of the crime' so to speak — and try to reconstruct what happened. Geological formations contain clues to their historical origins.  Geologists, like detectives, must find and organize these clues in order to reconstruct a formation’s history.  This is how they study the changing structure of the earth, its composition, and the forces that have shaped it over eons.

The format for this class includes lectures (with numerous color graphics), video clips, reading, laboratory experiments, and investigative homework assignments.

  • The curriculum consists of several geological disciplines:

    • Physical Geology: Earth’s interior, erosion, deposition, landforms, mountains, volcanoes.
    • Historical Geology: History of the earth, fossils, ancient geographies, geologic column.
    • Minerology & Petrology: Properties of rocks and minerals.
    • Structural Geology: Tectonic structures, deformational forces which shape rocks, etc.
    • Geophysics: Earthquakes, internal structure, magnetic field, heat flow, pressure, gravity.
    • Hydrology: Water cycle, groundwater, caves, rivers, lakes, glaciers, etc.
    • Economic Geology: Mineral resources such as ores, fossil fuels, building materials.

The section on rocks and minerals is an expanded 6-week unit which involves a closer look at their origins and properties.  Students will be testing and examining specimens from a collection kit which they will purchase for the class ($75).  They will also learn how to develop their own collections.  

In place of exams, students will incrementally develop a booklet on the geology of their state—its tectonic history, rocks, minerals, underlying strata, surface features, earthquakes, hydrology, and geologic resources.  The project is divided into several bi-weekly homework assignments which are synchronized with the lessons.  This will provide students with the opportunity to use and apply their knowledge in a more concrete way.

This class is open to students age 13 and up.  Material and homework assignments are scaled according to grade level.

Geology is part of CLRC’s Earth Science series, which also includes Astronomy (one semester) and Meteorology (one semester).

NOTE:  Owing to delays in delivery, parents are strongly encouraged to order books and equipment at least 3 weeks before class begins.  These materials will be needed the first week of class.

"My daughter loved Dr. DiPuccio's Geology class! The cumulative format of the class was very helpful, and Dr. DiPuccio's enthusiasm and presentation of the material inspired her with a love for the subject. This was one of her favorite classes ever!"

William DiPuccio, Ph.D.

william-dipuccio-clrcBill DiPuccio  recently served as an instructor in Physical and Earth Science at Heritage Classical Academy near Akron, Ohio. He has been teaching science since 2002 including a position as science instructor and department head for five years at St. Nicholas Orthodox School, a classical school in Akron, OH. He has designed and taught laboratory courses in biology, earth science, astronomy, chemistry, and physics for elementary school, middle school, and high school. Bill has also, trained elementary school teachers, and taught numerous summer and weekend science camps.

Bill has a Ph.D. in historical theology and a professional background in meteorology, engineering (ultrasonic and electromagnetic polymer joining processes, automation) and graphic design. His academic interests and publications can be found on his blog,
