Rivers and Streams part of Cutting Edge:Introductory Courses:Activities
This lab activity has students collect stream data in the field and calculate flow velocity, discharge and gradient. Additional activities include plotting clast size on a Hjulstrom Diagram, and unit conversions.

Prework for Rivers and Streams Lab (Intro Geology) part of Quantitative Skills:Activity Collection
This activity is part of a collection under development by participants in a June 2006 workshop. Tested versions will be available soon. In order to give Introductory Geology (Physical Geology) undergraduate non-majors students experience and confidence in using basic algebra to calculate very simple stream flow properties, we use a prework assignment prior to the Rivers and Streams Lab. Prework is a worksheet assigned 2 weeks in advance, which asks students to calculate velocity and discharge as well as unit conversions and calculations of stream load. The questions are put into the context of activities they completed earlier in the semester during visits to the stream (on campus) so questions are relevant to their previous experiences. The prework timeframe gives students the opportunity to seek extra help from their instructor prior to the lab period in which they will make additional measurements, similar calcualations and interpretations of their data.

General Geology part of Cutting Edge:Introductory Courses:Courses
General Geology at CSU Chico is an introduction to physical geology in which students learn about the origin of the earth, rocks and minerals, development of geologic landforms and processes. The lab component of this course includes hands on activities to explore these topics.

General Geology part of Quantitative Skills:Courses
This is the lab section of the introductory physical geology class. Lab activities are designed to be hands on activities for students to better understand broad topics discussed in the "lecture" section of the course. Lab sections do not always correlate with lecture sections or instructors, so our 15-18 sections must be run uniformly, generally by graduate student TA's. Activities include identification of rocks and minerals, map activities, 2 off campus fieldtrips, rivers and streams, groundwater, and earthquakes.
