Why should you be interested in earth science?
Please view this short video on U-Tube
My primary professional interests are in geoscience education. I want to bring as much of the vastness and complexity of the earth to my students both in and out of class. As part of that, I am involoved in several projects that are trying to reach out to, not only my students, but also the Waubonsee community.
- Waubonsee Community College is an Educational Affiliate in the IRIS consortium (Incorporated Research Institutions for Seismology), a group dedicated to exploring the earth's interiori and using geophysics and earthquake science. As part of this membership we received an AS-1 seismograph, which has been collecting data since June of 2005. The AS-1 is prominently displayed in our Science Building, and its data is used in our Earth Science and Geology classes and labs. You can see a real-time view of our data here.
- Click here to see how our AS1 has contributed to the IRIS (IRI) regional network of seismometers
- Click here for a list of recent earthquakes
- Click here for an interactive viewer of data from the most recent earthquakes
- I am interested in the issue of sustainablity, and improving the sustainability of myself, my stidents, and the Waubonsee community. I gave a presentation in our Asset Earth seires on sustainability, the powerpoint slides can be found here(I have removed images that might have copyright issues). A list of readings and webites can be found here.
- Waubonsee Community College, in cooperation with the City of Aurora, the Illinois State Museum, and the Illinois State Geological Survey, undertook a systematic archeologic dig to uncover a rumoured mastodont (this is not a typo) under Mastodon Lake in Phillips Park, in Aurora, IL. We didn't find the rumoured mastodont left after the WPA project in the 1930's, but we did uncover significant background data and samples which provides a clearer understanding of the paleoenvironment the Aurora mastodonts lived in, 10,000 to 13,000 years ago.

This 3 credit course is designed so the student will demonstrate a familiarity with the basic vocabulary of meteorology, geology, and some oceanography. The student will demonstrate an ability to examine earth science information through critical reading, writing, and discussion. In doing so, the student will realize the wonders and complexities of the fragile Planet Earth upon which they are a steward. The student will be able to more fully understand the stewardship role they are undertaking by developing an understanding of the geologic concepts and data that are at the core of current discussions of topics such as climate change, environmental hazards, and sustainable resource management. Specific objective sheets will be distributed which should be used as study guides for exams. IAI: P1905
This 3 credit course is designed so the student will demonstrate a familiarity with the basic vocabulary and concepts of modern astronomy. The student will demonstrate an ability to examine astronomic information through critical reading, writing, and discussion. Through an understanding of ideas and concepts in astronomy, the student will be able to more fully understand the complexities of one of the fundamental questions of humankind: What was the beginning of the universe like? Along the way, students will discover the contents and composition of our solar system, our own galaxy, and some of the galaxies in the great beyond, and perhaps beyond the edge. Specific objective sheets for each exam will be distributed, which should be used as a study guide. IAI: P1 906
This 3 credit course is designed so the student will demonstrate a familiarity with the concepts and basic vocabulary of physical geology. The student will demonstrate an ability to examine geological information through critical reading, writing, and discussion. The student will gain an appreciation of the geologic materials and processes that govern, and have governed their familiar physical landscape. Specific objective sheets will be distributed which should be used as study guides for exams. IAI: P1 907
A laboratory course meant to be taken concurrently with Introduction to Physical Geology (GLG 100). Weekly laboratory work will involve mineral and rock identification, topographic and geologic map exercises, and some field work. IAI P1 907L
(GLG101, Spring 2011)
This course is an introduction to the origin and structure of the earth through a study of the evolution of its life and continents over the last 4.6 billion years. Emphasis is placed on the formation and interpretation of sedimentary rocks for the purpose of understanding how they, and the fossils contained within them, record changes in the Earth’s environment and processes over time. Plate tectonics and extinctions recorded in rocks are studied to understand how they reflect environmental changes in the Earth's ocean, atmosphere, and surface. Required field trips are an integral part of the course. IAI: P1 907L
This course is intended to address issues that have not traditionally been considered in most environmental discussions. In so doing, this course will contribute to a better trained environmental scientist, a more informed student, and future elector to be able to solve critical local and global environmental issues in the new millennium. These issues include recognition and mitigation of geologic hazards (floods, landslides, subsidence, earthquakes, and volcanoes), groundwater contamination, the source and supply of energy and mineral resources, as well as global warming and climate change. IAI: P1 908
Geology of the National Parks develops geological background, concepts and principles through the study of selected national parks. Students articulate the reasons why sites are designated as national parks, monuments, and seashores and the role that geology has in determining that status. Basic geologic concepts discussed are minerals, rocks, geologic time, sedimentary environments and rivers, plate tectonics, volcanoes, weathering, mass wasting, earthquakes, and glaciers and glaciation. Human interactions and archeology are presented where appropriate. IAI: P1 907
This course in Physical Geography is designed so the student will demonstrate a familiarity with the basic vocabulary and a working knowledge of the dimensions and processes of many of the environments and systems of the Earth. This will be accomplished by examining the fundamental atmospheric, tectonic, and geomorphic processes that are part of the dynamic, yet fragile planet Earth. IAI: P1 909L
