Integrating Quantitative Activities in Rivers and Streams Lab

This study explores the incorporation of quantitative activities in an introductory geology lab at CSU Chico, focusing on stream measurements and analysis. Activities include stream velocity determination, rock identification, and contour line interpretation. Pre-work calculations cover stream velocity, discharge, and volume, with opportunities for data comparison and analysis. The lab culminates in field trips to study the geology of Upper Bidwell Park, examining erosion, transportation, and deposition processes in rivers and streams.

Presentation Transcript

  1. Attempts at Integrating Quantitative Activities in “Rivers and Streams” Lab for Introductory Geology at CSU Chico Rachel Teasdale, CSU Chico

  2. The Syllabus- with Streams Activities

  3. Week 1: Campus Walk • Activities: • “preview” a variety of future lab topics • graded, but general enough for students who add the course late • establishes a sense of course rigor/expectations • the first set of (simple!) quantitative experiences. Lab 1 Activities: Stream measurements on campus Rock ID (TA’s ID) intro to contour lines/topo maps piezometer water levels intro to seismograph

  4. floating orange (or stick/pinecone) 100’ Week 1: Campus Walk • Stream Activities: • Determine pace • Use pace to measure 100’ along creek • Determine velocity of creek • Measurements collected from Big Chico Creek, on campus

  5. Week 9: Fieldtrip Geology of Upper Bidwell Park • rock ID • outcrop sketches/ interpretations • topo maps • stream velocity

  6. The Syllabus- with Streams Activities

  7. Pre-work Calculations • stream velocity • stream discharge • stream volume (in 24 hours) • weight of water & unit conversions • questions using dissolved solids & unit conversions Fig 9.3, Lutgens & Tarbuck , 8th Edition Week 12: Pre-work • Pre-work review of • concepts (hopefully covered) in lectures and • calculations used to describe stream flow. • opportunity to seek help with calculations from TA’s before the Rivers & Streams Lab.

  8. Week 12: Pre-work … and start entering data to be used in lab to compare Week 1 & Week 13 data

  9. Week 13: Rivers & Streams • Stream Activities: • Measure stream width, depth • Calculate discharge • Consider data quality/applicability up/down stream • Measure cobble sizes (& ID rock type) • Use Chico Quad to determine stream gradient

  10. Week 13: Rivers & Streams Erosion Avg velocity (cm/s) Transportation Deposition Diameter of clasts (mm)

  11. Week 13: Rivers & Streams Comparison of data • From January to that collected in April • From previous semester (Fall data = Sept/Nov) • NEW STUFF: • Compare one year’s worth of data to previous years • Compare our data with California Department of Water Resources BIC station

  12. Other ideas? (AKA HELP!!!!)
