1. Pacific NW Geology

2. Course Goals 1.Analyze geologic features for rock type and depositional history and interpret the geologic history 2.Develop place-based guided-inquiry field trips and lab exercises for secondary students that is aligned with content standards 3.Describe the basic chronology of geologic events in the Pacific Northwest of North America. 4.List and describe the key geographic/geologic regions of the Pacific Northwest 5.Construct a conceptual W-E cross-section of the Pacific NW for various times in the geologic past 6.Analyze earth science literature written for geologists and the general public, extract the key points, and restate it in both written and picture form to be understandable to secondary students Content skill/knowledgeTeaching application

8. What past events are recorded in this salt marsh?

9. What to do… Students should make observations about: Students should make observations about: –The layers they observe –The grain size variation throughout –“Breaks” in the lateral continuity of the layers –Any weathering they observe –FOSSILS?!

13. The World during the Precambrian http://www.earthscape.org/t2/scr01/scr01ab.html Before 540 million years ago Millions and millions of year ago, during the Precambrian, our world was a different place. Most of the world was covered with water; only some of the land we see today was visible in Precambrian time. The northeast portion of land, on the North American continent, was at the surface. (see the map at the right.) http://www.scotese.com(Alt & Hyndman, 1995) What our world looked like in the Precambrian. 1

14. Life in the Precambrian (Plants and Animals) http://www.paleoportal.org Life during the Precambrian was sparse, nothing like today! Life was small! The most common form of life was blue-green algae (blue-green algae is like the green scum that grows in fish tanks). This blue-green algae was amazing, as it breathed, taking in carbon dioxide (what you breathe out) and expelling oxygen (what you breathe in). During the many millions of years of the Precambrian, blue-green algae created a whole lot of oxygen that then allowed more small life to form. Rocks showing layers of algae that are from the Precambrian. Near the end of the Precambrian there were very few invertebrates (animals without a backbone) living. These invertebrates looked like mutated jellyfish and worms. (Alt & Hyndman, 1995) Invertebrate fossil 3
