How to be a field geologist: an in-class exercise to introduce students to basic outcrop analysis part of Cutting Edge:Geoscience in the Field:Activities
This in-class exercise is designed to give students practice analyzing outcrops before they go on a field trip. First, students watch a short video tutorial on analyzing an outcrop. Then, they are given a color photograph of an outcrop and a hand sample and complete a field notebook entry for the outcrop.
Evaluating the lines of evidence for plate tectonics part of Integrate:Workshops:Teaching the Methods of Geoscience:Activities
In this in-class exercise, students compare several lines of evidence that support the ideas of continental drift and plate tectonics. Before the class meeting, each student is given a preparation assignment in which he/she studies one "continental drift" and one "ocean floor data" map. In class, students divide into teams of 3, with each team member having prepared different specialties. They discuss their respective maps and look for spatial patterns among the data.
OCEA10: Introduction to oceanography part of Cutting Edge:Oceanography:Courses
Even though the majority of the Earth's surface is covered by seawater, the average person is less aware of what is happening in the ocean than what is happening on land. In this course, we will work together to answer several fundamental questions: Which factors control life in the ocean? How do we know what we know about the ocean? What's at the bottom of the ocean? How does the water in the ocean move? How are human activities and climate change altering the ocean? OCEA 10 provides an introduction to the ocean environment, including geological, chemical, physical, and biological oceanography topics.
Field studies, Central California part of Integrate:Workshops:Teaching the Methods of Geoscience:Course
Field studies of Central California is an introductory field geology course for community college students. Students meet for 3 hours per week of lecture, take one 4-day field trip to the Eastern Sierras to study volcanic and glacial processes, and take one 3-day field trip to Morro Bay to study coastal processes. Major topics include plate tectonics, rock identification, outcrop analysis, map interpretation, volcanic processes, glacial processes, marine taxonomy, and coastal geology, all with an emphasis on Central California.
Developing meaningful and manageable research opportunities for community college students: lessons learned from semester #1 part of Geoscience in Two-year Colleges:Supporting and Advancing Geoscience Education in Two-Year Colleges:Workforce, Transfer, and Careers:Preparing Students in Two-year Colleges for Careers:Essays
Each semester, there are a handful of students in the science building every day working at the tables outside of the classrooms, dropping by office hours with hand samples, and asking questions after class related to, but beyond the scope of, the topic covered that day. They are the "repeat offenders" who have taken several courses in the department and are hungry for more. But when I say "more", I don't mean yet another rock identification lab or plate tectonics lecture...
